[0002] This application contains a sequence list in a computer-readable form, which is incorporated herein by reference. Background of the Invention
[0003] Invention Field
[0004] This invention relates to animal feeds or animal feed additives containing polypeptides with protease activity and their uses. It also relates to methods for producing these proteases and for using proteases to improve animal performance and the nutritional value of animal feed. Background of the Invention
[0006] In the use of proteases (in vivo) in animal feed, and / or the use of such proteases for processing plant proteins (in vitro), it is important to note that protein is an essential nutrient for both animals and humans. Most livestock and many people obtain these essential proteins from plant-based protein sources. Important plant-based protein sources include, for example, oilseed crops, legumes, and cereals.
[0007] When soybean meal, for example, is included in the feed of monogastric animals such as pigs and poultry, a significant proportion of soybean meal is not effectively digested (the apparent ileal protein digestibility in piglets, growing pigs, and poultry such as broilers, laying hens, and roosters is only about 80%).
[0008] The gastrointestinal tract of animals consists of a series of segments, each exhibiting a distinct pH environment. In monogastric animals such as pigs and poultry, as well as many types of fish, the stomach is potentially highly acidic with a pH as low as 1–2, while the intestine has a more neutral pH of around 6–7.5. In addition to the stomach and intestine, poultry possess a crop preceding the stomach. The pH of the crop is primarily determined by the digested feed and is therefore typically in the pH range of 4–6. Protein digestion by a protease can occur throughout the digestive tract, provided that the protease is active and survives the conditions of that digestive tract. Therefore, proteases that are highly acid-stable and thus can survive in the gastric environment, while simultaneously being effectively active across a wide range of physiological pH levels in the target animal's digestive tract, are particularly desirable.
[0009] Since animal feed is typically formulated in granular form, where steam is used in the granulation process, it is desirable that the proteases used in animal feed remain active after exposure to the steam treatment.
[0010] In order to produce proteases for industrial use, it is important to produce proteases in high yields so that a sufficient quantity of the product can be obtained to supply the proteases at a favorable price.
[0011] Related technical specifications
[0012] Proteases from the S1 family are known in the art and are used in animal feed. For example, WO01 / 58275 discloses the use of acid-stable proteases from the subtilis protease family in animal feed. WO 01 / 58276 discloses the use of acid-stable proteases (10R proteases) derived from Nocardia spp. NRRL 18262 and proteases derived from Nocardia albopictus DSM 14010 in animal feed. WO 04 / 072221, WO 04 / 111220, WO 04 / 111223, WO 05 / 035747, and WO 05 / 123911 disclose proteases related to 10R proteases and their use in animal feed. WO 04 / 072279 discloses the use of other proteases in animal feed. WO 04 / 034776 discloses the use of Bacillus subtilis protease / keratinase, PWD-1 from Bacillus licheniformis, in poultry feed.
[0013] Soybeans and corn are two highly used protein sources in agriculture, and therefore, it is important that proteases exhibit good activity against these substrates. Numerous studies have disclosed the activity of proteases from various bacterial sources on soybean-corn flour, including species of *Kribbella* (WO 2013 / 026796), *Rhodotorula sacchariformis* (WO 2013 / 110766 and WO 2014 / 122161), *Saccharomyces viride* (WO 2013 / 189972), *Saccharomyces australis* (WO 2013 / 041689), and species of *Dactylogyrus* (WO 2014 / 096259).
[0014] Furthermore, proteases isolated from other bacterial species (e.g., Janibacter sp.) are known in the art. Thrash et al. performed a shotgun genome sequencing of the bacterium HTCC2649, as described in “Genome sequence of the Marine Janibacter Sp. Strain HTCC2649”, 2011, J. Bacteriol. 193:584-585, which has been submitted to EMBL / GenBank under accession number AAMN01000001. From this genome sequencing, the polypeptide with Uniprot number A3TJ83 (SEQ ID NO:2 in this paper) was annotated as a serine protease.
[0015] Yoshida et al. performed a whole-genome shotgun biopsy of the bacterium Austwickia chelonae NBRC 105200, which was submitted to the EMBL / GenBank / DDBJ databases. The peptidase (Uniprot:K6VM97, SEQ ID NO:9) from these databases was annotated with SEQ ID NO:5 (corresponding to the mature polypeptides of SEQ ID NO:2 and 4 in this paper) having 62.1% sequence identity.
[0016] Commercial products containing a protease and sold for use in animal feed include ProAct (DSM NP / Novozymes) (DuPont) (DuPont) (DuPont), Allzyme TM (Alltech) (BioResources, Int., Poultrygrow) TM (Jefo) and (Novus).

[0061] definition
[0062] Peptide activity against soybean-corn flour: The term "peptide activity against soybean-corn flour" refers to the protease activity of an enzyme against a 30:70 mixture of soybean and corn flour, determined using o-phthalaldehyde (OPA) assays as described herein. Examples of pH measurements are pH 3.0, 4.0, 5.0, 6.0, and 7.0. Examples of temperature measurements are 30°C, 35°C, 40°C, 45°C, and 50°C. Examples of time measurements are 2, 3, and 4 hours. Examples of enzyme concentrations are 50, 100, 150, 200, 250, and 300 mg enzyme protein / kg dry matter substrate.
[0063] In a preferred embodiment, the activity of the peptide against soybean-corn flour was determined by the following: Soybean-corn flour (1 g) mixed at a 30:70 ratio was added to a buffer solution containing 100 mM succinic acid, 100 mM HEPES, 100 mM CHES, 100 mM CAPS, 1 mM CaCl2, 150 mM KCl, and 0.01% Triton X-100 (10 mL). This buffer solution had been prepared and adjusted to a pH of 3.0, 4.0, 5.0, 6.0, or 7.0 after the soybean-corn flour substrate was mixed with the assay buffer. Then, an aliquot of the substrate slurry (2 mL) was mixed for 30 min. A solution dissolved in 100 μl of 100 mM sodium acetate buffer (9.565 g / L NaOAc, 1.75 g / L acetic acid, 5 mM...) was added. The protease (200 mg enzyme protein / kg dry matter) was prepared in CaCl2, 0.01% BSA, 0.01% Tween 20, pH 6.0; the sample was incubated at 40°C (500 rpm) for 3 hours; the sample was centrifuged (10 min, 4000 rpm, 0°C); and the supernatant was collected for analysis using o-phthalaldehyde (OPA) assay (referred to herein as the “soybean-corn flour assay”). In another preferred embodiment, as described in Example 4 herein, the activity of the peptide against soybean-corn flour was determined.
[0064] In one embodiment, the polypeptide of the present invention, such as SEQ ID NO:5, exhibits at least 30%, for example, at least 40%, at least 65%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 100% activity against soybean-corn flour at pH 4. In another embodiment, the polypeptide of the present invention, such as SEQ ID NO:5, exhibits at least 40%, for example, at least 65%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 100% activity against soybean-corn flour at pH 5.
[0065] Allelic variants: The term "allelic variant" refers to any of two or more alternative forms of a gene occupying the same chromosomal locus. Allelic variations arise naturally from mutations and can lead to polymorphism within a population. Gene mutations can be silent (without alteration in the encoded polypeptide) or can encode a polypeptide with a modified amino acid sequence. Allelic variants of a polypeptide are polypeptides encoded by allelic variants of a gene.
[0066] Animals: The term "animal feed" refers to all animals other than humans. Examples of animals include non-ruminants and ruminants. Ruminants include, for example, animals such as sheep, goats, cattle (e.g., beef cattle, dairy cows, and calves), deer, yank, camels, llamas, and kangaroos. Non-ruminant animals include monogastric animals, such as pigs (including but not limited to piglets, growing pigs, and sows); poultry, such as turkeys, ducks, and chickens (including but not limited to broilers and laying hens); horses (including but not limited to hot-blooded horses, cold-blooded horses, and warm-blooded horses), calves; fish (including but not limited to amberjack, arapaima, flounder, bass, bluefish, bocachico, cyprinids, catfish, cachama, carp, catfish, catfish, flounder, charfish, cichlids, cod, sunfish, golden snapper, croaker, eel, goby, goldfish, gudgeon, grouper, guapote, halibut, Java fish, and scad). Fish, lai, loach, mackerel, milkfish, silver perch, mudfish, mullet, paco, pearlspot, pejerrey, perch, pike, pomfret, bream, salmon, sampa, Canadian yellowtail, black perch, sea bream, shiner, sleeper shark, blackfish, sea bream, flounder, sashimi, sturgeon, ocean sunfish, sweetfish, trevally, tilapia, trout, tuna, turbot, white trout, whitebait, and whitefish); and crustaceans (including but not limited to shrimp and prawns).
[0067] Animal feed: The term "animal feed" refers to any compound, preparation, or mixture suitable for, or intended for, to be ingested by animals. Animal feed for monogastric animals typically includes concentrates along with vitamins, minerals, enzymes, direct-feeding microorganisms, amino acids, and / or other feed ingredients (e.g., in premixes), while animal feed for ruminants typically includes forage (including roughage and silage) and may further include concentrates along with vitamins, minerals, enzymes, direct-feeding microorganisms, amino acids, and / or other feed ingredients (e.g., in premixes).
[0068] Weight gain: The term “weight gain” refers to the increase in the live weight of an animal during a given period of time, such as the weight gain from day 1 to day 21.
[0069] cDNA: The term "cDNA" refers to a DNA molecule that can be prepared by reverse transcription from mature, spliced mRNA molecules derived from eukaryotic or prokaryotic cells. cDNA lacks the intron sequences that can be present in the corresponding genomic DNA. Early initial RNA transcripts are precursors to mRNA, undergoing a series of processing steps, including splicing, before becoming mature, spliced mRNA.
[0070] Coding sequence: The term "coding sequence" refers to a polynucleotide that directly identifies the amino acid sequence of a polypeptide. The boundaries of a coding sequence are generally determined by an open reading frame, which begins with a start codon (such as ATG, GTG, or TTG) and ends with a stop codon (such as TAA, TAG, or TGA). Coding sequences can be genomic DNA, cDNA, synthetic DNA, or a combination thereof.
[0071] Composition: The term "composition" refers to a composition comprising a carrier and at least one enzyme of the present invention. The composition described herein can be mixed with animal feed and can be referred to as "powdered feed".
[0072] Concentrates: The term “concentrate” refers to feeds with high protein and energy concentrations, such as fishmeal, molasses, oligosaccharides, sorghum, seeds and grains (e.g., whole or prepared from corn, oats, rye, barley, wheat, or by crushing, milling, etc.), oilseed filter cake (e.g. from cottonseed, safflower, sunflower, soybean, rapeseed / canola, peanut, or peanut kernel), palm kernel cake, yeast-derived materials, and distillers' grains (e.g., wet distillers' grains (WDS) and dry distillers' grains with solubles (DDGS)).
[0073] Control Sequences: The term "control sequence" refers to the nucleic acid sequence necessary for the expression of the polynucleotide encoding the mature polypeptide of the present invention. Each control sequence may be native (i.e., from the same gene) or exogenous (i.e., from different genes) for the polynucleotide encoding the polypeptide, or native or exogenous relative to each other. Such control sequences include, but are not limited to, precursors, polyadenylated sequences, propeptide sequences, promoters, signal peptide sequences, and transcription terminators. At a minimum, control sequences include promoters, as well as transcription and translation termination signals. These control sequences may be provided with multiple linkers for the purpose of introducing specific restriction enzyme sites that facilitate the linking of these control sequences to the coding regions of the polynucleotide encoding the polypeptide.
[0074] European Production Efficiency Factor (EPEF): The term "European Production Efficiency Factor" is a term used to determine production efficiency, taking into account feed conversion ratio, mortality rate, and daily weight gain. EEF is calculated as [(survival rate (%) × body weight gain (kg)) / (study duration in days) × FCR)] × 100.
[0075] Expression: The term “expression” includes any step involved in the production of a polypeptide, including but not limited to transcription, post-transcriptional modification, translation, post-translational modification, and secretion.
[0076] Expression vector: The term "expression vector" refers to a linear or circular DNA molecule that contains a polynucleotide encoding a polypeptide and that the polynucleotide is operatively linked to a control sequence provided for its expression.
[0077] Feed conversion ratio: The term "feed conversion ratio" refers to the amount of feed given to an animal to increase its body weight by a specified amount. Improved feed conversion ratio refers to a lower feed conversion ratio. "Lower feed conversion ratio" or "improved feed conversion ratio" means that the use of the feed additive composition in the feed results in a lower amount of feed being given to the animal to increase its body weight by a specified amount, compared to the amount of feed required to increase the animal's body weight by the same amount when the feed does not contain the feed additive composition.
[0078] Feed efficiency: The term "feed efficiency" refers to the weight gain per unit of feed when an animal is fed randomly or in a specified amount of food over a period of time. "Increased feed efficiency" refers to the increased weight gain per unit of feed intake resulting from the use of the feed additive composition according to the invention in feed, compared to animals fed without the present feed additive composition.
[0079] Forage: As defined herein, the term “forage” also includes coarse grains. Forage is fresh plant material, such as hay and silage derived from forage plants (grasses) and other forage plants (seagrass, germinated grains, and legumes) or any combination thereof. Examples of forage plants are alfalfa (lucerne), birdsfoot, brassica (e.g., kale, canola, turnip), radish), clover (e.g., mixed clover, red clover, ground clover, white clover), grasses (e.g., Bermuda grass, bromegrass, false oat grass, fescue, heath grass, Kentucky bluegrass, orchard grass, ryegrass, timothy-grass), corn, millet, barley, oats, rye, sorghum, soybeans, and wheat, and vegetables (e.g., sugar beets). Forage further includes crop residues from cereal products (such as corn stalks, straw from wheat, barley, oats, rye and other cereals), residues from vegetables such as beet tops, residues from oilseed products such as stems and leaves from soybeans, rapeseed and other legumes, and portions from cereal refining processes for animal or human consumption or from fuel production or other industries.
[0080] Fragment: The term "fragment" refers to a polypeptide in which one or more (e.g., several) amino acids are missing from the amino and / or carboxyl termini of a mature polypeptide; wherein the fragment has protease activity. In one aspect, the fragment comprises at least 173 amino acid residues (e.g., amino acids 16 to 188 of SEQ ID NO:2, SEQ ID NO:4, or SEQ ID NO:5), at least 177 amino acid residues (e.g., amino acids 12 to 188 of SEQ ID NO:2, SEQ ID NO:4, or SEQ ID NO:5), at least 181 amino acid residues (e.g., amino acids 10 to 190 of SEQ ID NO:2, SEQ ID NO:4, or SEQ ID NO:5), at least 185 amino acid residues (e.g., amino acids 9 to 193 of SEQ ID NO:2, SEQ ID NO:4, or SEQ ID NO:5), at least 190 amino acid residues (e.g., amino acids 7 to 196 of SEQ ID NO:2, SEQ ID NO:4, or SEQ ID NO:5), or at least 195 amino acid residues (e.g., amino acids 5 to 199 of SEQ ID NO:2, SEQ ID NO:4, or SEQ ID NO:5).
[0081] In another embodiment, the fragment comprises at least 174 amino acid residues (e.g., amino acids 16 to 189 of SEQ ID NO:11, SEQ ID NO:13, or SEQ ID NO:14), at least 178 amino acid residues (e.g., amino acids 12 to 189 of SEQ ID NO:11, SEQ ID NO:13, or SEQ ID NO:14), at least 182 amino acid residues (e.g., amino acids 10 to 191 of SEQ ID NO:11, SEQ ID NO:13, or SEQ ID NO:14), at least 186 amino acid residues (e.g., amino acids 9 to 194 of SEQ ID NO:11, SEQ ID NO:13, or SEQ ID NO:14), at least 191 amino acid residues (e.g., amino acids 7 to 197 of SEQ ID NO:11, SEQ ID NO:13, or SEQ ID NO:14), or at least 196 amino acid residues (e.g., amino acids 5 to 200 of SEQ ID NO:11, SEQ ID NO:13, or SEQ ID NO:14).

Non-limiting examples of separated substances include (1) any substance that is not naturally occurring, (2) any substance including but not limited to any enzyme, variant, nucleic acid, protein, peptide or cofactor that is at least partially removed from one or more of the naturally occurring components associated with it; (3) any substance that is artificially modified relative to a naturally found substance; or (4) any substance modified by increasing the amount of the substance relative to other components naturally associated with it (e.g., recombinant production in a host cell; multiple copies of the gene encoding the substance; and the use of a promoter stronger than the promoter naturally associated with the gene encoding the substance).
[0085] Mature polypeptide: The term "mature polypeptide" refers to a polypeptide in its final form after translation and any post-translational modifications such as N-terminal processing, C-terminal truncation, glycosylation, phosphorylation, etc. In one aspect, based on the SignalP program (Nielsen et al., 1997, Protein Engineering 10:1-6), the mature polypeptide is amino acids 1 to 203 of SEQ ID NO:2, and amino acids -200 to -171 of SEQ ID NO:2 are the signal peptide.

[0088] It is known in the art that host cells can produce mixtures of two or more different mature polypeptides (i.e., with different C-terminal and / or N-terminal amino acids) expressed from the same polynucleotide. It is also known in the art that different host cells process polypeptides differently, and therefore a host cell expressing a polynucleotide can produce different mature polypeptides (e.g., with different C-terminal and / or N-terminal amino acids) compared to another host cell expressing the same polynucleotide.
[0089] Mature polypeptide coding sequence: The term "mature polypeptide coding sequence" refers to a polynucleotide encoding a mature polypeptide with protease activity. In one aspect, based on the SignalP program (Nielsen et al., 1997, see above), the mature polypeptide coding sequence is nucleotides 601 to 1209 of SEQ ID NO:1, and nucleotides 1 to 90 of SEQ ID NO:1 encode a signal peptide. In another aspect, based on EDMAN N-terminal sequencing data and complete MS data of the polypeptide of SEQ ID NO:4, the mature polypeptide coding sequence is nucleotides 592 to 1200 of SEQ ID NO:3, and nucleotides 1 to 81 of SEQ ID NO:3 encode a signal peptide.
[0090] In another instance, based on the SignalP procedure (Nielsen et al., 1997, see above), the mature polypeptide encoding sequence is nucleotides 589 to 1200 of SEQ ID NO:10, and nucleotides 1 to 78 of SEQ ID NO:10 encode a signal peptide.

[0093] Obtained from or available from: The term "obtained from or available from" means that the polypeptide can be found in organisms from a specific taxonomic class. In one embodiment, the polypeptide is obtained from or available from the order Micrococcales (formerly known as Micrococcineae), where the term "order" is a taxonomic class. In another preferred embodiment, the polypeptide is obtained from or available from the family Intrasporangiaceae, where the term "family" is a taxonomic class.
[0094] If the taxonomic class of a polypeptide is unknown, it can be readily determined by a person skilled in the art by performing a BLASTP search of the polypeptide (using, for example, the National Center for Biotechnology Information (NCIB) website http: / / www.ncbi.nlm.nih.gov / ) and comparing it with the closest homologue. Unknown polypeptides that are fragments of known polypeptides are considered to belong to the same taxonomic species. Unknown native polypeptides or artificial variants, including substitutions, deletions, and / or insertions at up to 10 positions, are considered to originate from the same taxonomic species as known polypeptides.
[0095] Operable ligation: The term “operable ligation” refers to a construction in which a control sequence is positioned relative to the coding sequence of a polynucleotide such that the control sequence directs the expression of the coding sequence.
[0096] Granulation: The terms “granulation” and / or “granulation” refer to solid round, spherical and / or cylindrical flakes or granules, and the processes used to form such solid shapes, particularly feed granules and solid extruded animal feed. As used herein, the term “extrusion” (or extruding) is a well-known term in the art and refers to the process of forcing a composition through an orifice under pressure, as described herein.

[0098] Protease: The term “protease” is defined herein as an enzyme that hydrolyzes peptide bonds. The definition of protease also applies to the protease portion of the terms “parental protease” and “protease variant” as used herein. The term “protease” includes enzymes belonging to the EC 3.4.21 enzyme group (serine proteases). EC numbers are referenced to the 1992 Enzyme Nomenclature of NC-IUBMB Academic Press, San Diego, California, including supplements 1-5 published in *Eur. J. Biochem.* 223:1-5 (1994); *Eur. J. Biochem.* 232:1-6 (1995); *Eur. J. Biochem.* 237:1-5 (1996); *Eur. J. Biochem.* 250:1-6 (1997); and *Eur. J. Biochem.* 264:610-650 (1999). The naming conventions are regularly supplemented and updated; see, for example, the World Wide Web (WWW) at http: / / www.chem.qmw.ac.uk / iubmb / enzyme / index.html.
[0099] The proteases of the present invention and the proteases used according to the invention are selected from serine proteases of the peptidase family S1, as described in Biochem.J. 290:205-218 in 1993 and in the MEROPS protease database, issue 9.9 (August 23, 2013) (www.merops.ac.uk). This database is described in Rawlings, ND, Barrett, AJ, and Bateman, A., 2010, “MEROPS: the peptidase database,” Nucleic Acids Res. 38:D227-D233.
[0100] To determine whether a given protease is a serine protease or an S1 family protease, refer to the aforementioned manual and the principles described therein. This determination can be performed on all types of proteases, regardless of whether they are naturally occurring or wild-type, or genetically engineered or synthetic.
[0101] Protease activity: The term "protease activity" refers to proteolytic activity (EC 3.4). Peptides or proteases exhibiting protease activity are sometimes also designated as peptidases, prions, peptide hydrolases, or proteolytic enzymes. Proteases can be exopeptidases that hydrolyze peptides originating from either end or endopeptidases that function within the polypeptide chain. Endopeptidases exhibit activity against peptide substrates with N- and C-terminal closures, the specificity of which depends on the protease in question.
[0102] Several types of protease activity exist, such as trypsin-like proteases that cleave at the carboxyl terminus of Arg and Lys residues, and chymotrypsin-like proteases that cleave at the carboxyl terminus of hydrophobic amino acid residues. The protease of the present invention is a serine endopeptidase (EC 3.4.21) with a slightly alkaline optimal pH (optimal pH 8-9.5).
[0103] Any assay can be used to measure protease activity, employing a substrate that includes peptide bonds specific to the protease in question. pH and temperature assays are equally applicable to the protease in question. Examples of pH assays are pH 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12. Examples of temperature assays are 15°C, 20°C, 25°C, 30°C, 35°C, 37°C, 40°C, 45°C, 50°C, 55°C, 60°C, 65°C, 70°C, 80°C, 90°C, or 95°C. Examples of common protease substrates are casein, bovine serum albumin, and hemoglobin. In the classic Anson and Mirsky method, denatured hemoglobin is used as a substrate, and the amount of trichloroacetic acid-soluble hemoglobin is determined as a measure of protease activity after incubation with the protease in question (Anson, ML and Mirsky, AE, 1932, J. Gen. Physiol. 16:59 and Anson, ML, 1938, J. Gen. Physiol. 22:79).
[0104] For the purposes of this invention, assays described in "Materials and Methods" are used to determine protease activity, such as the Suc-AAPF-pNA assay and the Protazyme AK assay. For the Protazyme AK assay, when incubated with the protease, the insoluble Protazyme AK (azurin-crosslinked casein) substrate releases a blue color, and this color is determined as a measure of protease activity. For the Suc-AAPF-pNA assay, when incubated with the protease, the colorless Suc-AAPF-pNA substrate releases a yellow p-nitroaniline, and this yellow color is determined as a measure of protease activity.
[0105] The polypeptides of the present invention have at least 20%, for example, at least 40%, at least 65%, at least 70%, at least 80%, at least 90%, at least 95%, and at least 100% protease activity of the polypeptide of SEQ ID NO:5. In another embodiment, the polypeptides of the present invention have at least 20%, for example, at least 40%, at least 65%, at least 70%, at least 80%, at least 90%, at least 95%, and at least 100% protease activity of the polypeptide of SEQ ID NO:14. In another embodiment, the polypeptides of the present invention have at least 20%, for example, at least 40%, at least 65%, at least 70%, at least 80%, at least 90%, at least 95%, and at least 100% protease activity of the polypeptide of SEQ ID NO:20.

Version 6.1.0 is used. Optional parameters used are a vacancy opening penalty of 10, a vacancy extension penalty of 0.5, and an EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of the "longest consistency" annotated by Needle (obtained using the -non-simplification option) is used as the percentage consistency and calculated as follows:
[0109] (identical residues x 100) / (length of alignment - total number of vacancies in alignment)
[0110] For the purposes of this invention, the Niedleman-Wunsch algorithm (Needleman and Wunsch, 1970, ibid.) implemented in the Niedle program of the EMBOSS package (EMBOSS: European Molecular Biology Open Software Suite, Rice et al., 2000, ibid.) (preferably version 3.0.0 or later) is used to determine the degree of sequence identity between two deoxyribonucleotide sequences. Version 6.1.0 is used. Optional parameters used are a vacancy opening penalty of 10, a vacancy extension penalty of 0.5, and an EDNAFULL (EMBOSS version of NCBI NUC4.4) substitution matrix. The Niedle-annotated "longest consistency" output (obtained using the -non-simplified option) is used as the percentage of consistency and calculated as follows:
[0111] (Consistent deoxyribonucleotides x 100) / (Alignment length - total number of vacancies in the alignment)
[0112] Silage: The term "silage" refers to a fermented, high-moisture stored feed that can be fed to ruminants (cud-chewing animals, such as cattle and sheep) or used as a biofuel feedstock for anaerobic digesters. It is fermented and stored in a process called silage (ensilage, ensiling, or silaging) and is typically made from whole green plants (not just grains) of grasses or cereal crops (such as corn, sorghum, oats, rye, timothy, etc.) or legume crops (such as clover, trefoils, alfalfa, peas). Silage can be made from many field crops and, depending on the type, may use specific terms (oatlage for oats, haylage for alfalfa). Silage is made by placing cut green vegetation in silage pits, by piling it in large heaps covered with plastic sheets, or by wrapping large bales in plastic film.

[0128] Animal feed or animal feed additives containing peptides with protease activity
[0129] Soybeans and corn are two highly used protein sources in agriculture, and therefore it is important that proteases exhibit good activity toward these substrates. Furthermore, proteases exhibiting high activity across the entire gastrointestinal pH range (i.e., between approximately pH 3 and pH 7.5) would be of great significance, as they can be expected to degrade substrates more effectively shortly after ingestion and throughout most of the gastrointestinal tract.
[0130] Some proteases have been found to have surprisingly good pH-activity profiles for commercially relevant substrates (soybean-corn) and are significantly more active in a lower pH range (4-5) than protease 10R (SEQ ID NO:8), while maintaining comparable activity at neutral pH.

[0176] In one embodiment, the polypeptide has been isolated. The animal feed or animal feed additive preferably comprises or consists of the amino acid sequence of SEQ ID NO:5 or its allele variants; is a fragment having protease activity with a deletion of, for example, 30, 26, 22, 18, 13, 11, 8, or 5 amino acids from its N-terminus or C-terminus, or is a protease-active fragment comprising at least 173 amino acids, such as at least 177 amino acids, at least 181 amino acids, at least 185 amino acids, at least 190 amino acids, at least 195 amino acids, or at least 200 amino acids.

In another embodiment, the polypeptide has been isolated.
[0180] In a continuation of the fourth aspect, the present invention relates to animal feed or animal feed additives comprising one or more variants of SEQ ID NO:5, wherein the variant has protease activity and includes one or more substitutions, and / or deletions, and / or insertions or any combination thereof at positions 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49 or 50. In one embodiment, the number of positions including substitutions and / or deletions and / or insertions or any combination thereof in SEQ ID NO:5 is between 1 and 50, such as 1-45, 1-40, 1-35, 1-30, 1-25, 1-20, 1-15, 1-10, or 1-5 positions. In one embodiment, the number of positions including substitutions and / or deletions and / or insertions or any combination thereof in SEQ ID NO:5 does not exceed 10, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. In another embodiment, the number of substitutions and / or deletions and / or insertions in SEQ ID NO:5 does not exceed 10, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. In yet another embodiment, the number of substitutions in SEQ ID NO:5 does not exceed 10, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. In one embodiment, the polypeptide comprises one or more motifs VCG[E / Q]KVGQP (SEQ ID NO:15).
[0181] Amino acid alterations can be minor in nature, i.e., conserved amino acid substitutions or insertions that do not significantly affect protein folding and / or activity; small deletions typically of 1–30 amino acids; small amino- or carboxyl-terminal extensions, such as amino-terminal methionine residues; small linker peptides of up to 20–25 residues; or small extensions that facilitate purification by altering net charge or another function, such as multihistidine sequences, antigenic epitopes, or binding domains.
[0182] Examples of conserved substitutions are found in the following group: basic amino acids (arginine, lysine, and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine, and valine), aromatic amino acids (phenylalanine, tryptophan, and tyrosine), and small amino acids (glycine, alanine, serine, threonine, and methionine). Amino acid substitutions that generally do not alter specific reactivity are known in the art and are described, for example, by H. Neurath and R.R. Hill, 1979, in *The Proteins*, Academic Press, New York. Common substitutes are Ala / Ser, Val / Ile, Asp / Glu, Thr / Ser, Ala / Gly, Ala / Thr, Ser / Asn, Ala / Val, Ser / Gly, Tyr / Phe, Ala / Pro, Lys / Arg, Asp / Asn, Leu / Ile, Leu / Val, Ala / Glu, and Asp / Gly.
[0183] Alternatively, amino acid alterations have the property of changing the physicochemical properties of peptides. For example, amino acid alterations can improve the thermal stability of peptides, change substrate specificity, and alter the optimal pH.
[0184] Essential amino acids in peptides can be identified using methods known in the art, such as site-directed mutagenesis or alanine scanning mutagenesis (Cunningham and Wells, 1989, Science 244:1081-1085). In the latter technique, a single alanine mutation is introduced at each residue in the molecule, and the protease activity of the resulting mutant molecule is tested to identify amino acid residues essential to the molecule's activity. See also Hilton et al., 1996, Journal of Biochemistry 271:4699-4708. Alternatively, mutations in amino acids at hypothetical contact sites can be combined with physical analysis of the structure, such as by techniques like NMR, crystallography, electron diffraction, or photoaffinity labeling, to determine the enzyme's active site or other biological interactions. See, for example, de Vos et al., 1992, Science 255:306-312; Smith et al., 1992, Journal of Molecular Biology 224:899-904; Wlodaver et al., 1992, FEBS Lett. 309:59-64. The identity of essential amino acids can also be inferred from comparisons with related peptides.
[0185] S1 family peptidases comprise a catalytic triad in the order His, Asp, Ser. Mutations in any amino acid of this catalytic triad will result in changes or loss of enzyme activity or substrate specificity. For example, the amino acids in the catalytic triad of S1 protease 1 isolated from *Haloxylon ammodendron* HTCC2649 (SEQ ID NO:5) are His-35, Asp-62, and Ser-148. Similarly, the amino acids in the catalytic triad of S1 protease 1 isolated from *Terracoccus* sp. (SEQ ID NO:14) are His-35, Asp-62, and Ser-149. And the amino acids in the catalytic triad of S1 protease 1 isolated from *Nocturia flavum* (SEQ ID NO:20) are His-35, Asp-62, and Ser-149.
[0186] Single or multiple amino acid substitutions, deletions, and / or insertions can be made and tested using known mutagenesis, recombination, and / or truncation methods, followed by relevant screening procedures, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241:53-57; Bowie and Sauer, 1989, Proceedings of the National Academy of Sciences of the United States of America (Proc. Natl. Acad. Sci. USA) 86:2152-2156; WO 95 / 17413; or WO 95 / 22625. Other methods that can be used include error-prone PCR, phage display (e.g., Lowman et al., 1991, Biochemistry 30:10832-10837; US Patent No. 5,223,409; WO 92 / 06204), and region-directed mutagenesis (Derbyshire et al., 1986, Gene 46:145; Ner et al., 1988, DNA 7:127).
[0187] Mutagenesis / reorganization methods can be combined with high-throughput automated screening methods to detect the activity of cloned mutagenic peptides expressed by host cells (Ness et al., 1999, Nature Biotechnology 17:893-896). Mutagenic DNA molecules encoding active peptides can be recovered from host cells and rapidly sequenced using standard methods in the art. These methods allow for the rapid determination of the importance of individual amino acid residues within the peptide.
[0188] The polypeptide can be a hybrid polypeptide, in which a region of one polypeptide is fused to the N-terminus or C-terminus of a region of another polypeptide.
[0189] The polypeptide can be a fusion polypeptide or a cleavable fusion polypeptide, wherein another polypeptide is fused at the N-terminus or C-terminus of the polypeptide of the present invention. Fusion polypeptides are generated by fusing a polynucleotide encoding another polypeptide with the polynucleotide of the present invention. Techniques for generating fusion polypeptides are known in the art and include linking the coding sequences encoding the polypeptides such that they are within a frame and that the expression of the fusion polypeptide is under the control of the same promoter and terminator. Fusion polypeptides can also be constructed using integrin technology, wherein the fusion polypeptide is generated post-translationally (Cooper et al., 1993, EMBO J. 12:2575-2583; Dawson et al., 1994, Science 266:776-779).
[0190] Fusion peptides may further include a cleavage site between the two peptides. This site is cleaved upon secretion of the fusion protein, releasing both peptides. Examples of cleavage sites include, but are not limited to, those disclosed in the following literature: Martin et al., 2003, J. Ind. Microbiol. Biotechnol. 3:568-576; Svetina et al., 2000, J. Biotechnol. 76:245-251; Rasmussen-Wilson et al., 1997, Appl. Environ. Microbiol. 63:3488-3493; Ward et al., 1 995, Biotechnology 13:498-503; and Contreras et al., 1991, Biotechnology 9:378-381; Eaton et al., 1986, Biochemistry 25:505-512; Collins-Racie et al., 1995, Biotechnology 13:982-987; Carter et al., 1989, Proteins: Structure, Function, and Genetics 6:240-248; and Stevens, 2003, Drug Discovery World 4:35-48.
[0191] Carbohydrate molecules are typically attached to fungal-derived peptides during post-translational modifications. To aid in mass spectrometry analysis, the peptide can be incubated with an endoglucosidase to deglycosylate each N-linked site. For each deglycosylated N-linked site, an N-acetylglucosamine remains on the protein backbone.
[0192] In a fifth aspect, the present invention relates to animal feed or animal feed additives comprising one or more polypeptides having protease activity, wherein the polypeptide has at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100% sequence identity with the mature polypeptide of SEQ ID NO:11.

[0216] characteristic
[0217] Acidity / Alkalinity Characteristics
[0218] In some embodiments of the invention, the proteases of the invention exhibit beneficial properties with respect to pH, such as acid stability and optimal pH. Activity across a broad range of physiological pH (e.g., from 4-7) covers both the gastrointestinal tract (crown pH 4-6; stomach pH in pigs can sometimes be as high as pH 5-6) and the small intestine (pH 6-7). One embodiment of the invention is an isolated polypeptide exhibiting improved protease activity at 40°C between pH 3 and 7, for example, at pH 3.0, pH 4.0, pH 5.0, pH 6.0, and / or pH 7.0, compared to protease 10R.
[0219] Temperature-Activity
[0220] The temperature-activity profile of the protease can be determined as described in Example 3. Activity at low temperatures (37°C–50°C) can be advantageous for protein digestion in animals.
[0221] In one embodiment, the present invention comprises a protease having a temperature activity profile at pH 7.0 with a relative activity of 0.10 or higher at 37°C, a relative activity of 0.40 or higher at 50°C, or a relative activity of 0.80 or higher at 60°C, compared to the activity of a protease at 60°C (Comparative Example 3).
[0222] Another embodiment of the invention is an isolated polypeptide that has improved protease activity at pH 7.0, for example, 60°C or below, such as 50°C or below, 37°C or below, or between 37°C and 60°C, or between 50°C and 60°C, or at 37°C, or at 50°C, or at 60°C, compared to protease 10R at pH 6.5.
[0223] thermal stability
[0224] Thermal stability can be determined as described in Example 5, i.e., by using DSC measurements to determine the denaturation temperature (T) of the purified protease protein. d Td indicates the thermal stability of the protein: T d The higher the value, the higher the thermal stability. Therefore, in a preferred embodiment, the protease of the present invention has a T value. d The T d T higher than the reference protein d T d It is determined from purified protease samples (preferably having a purity of at least 90% or 95%, as determined by SDS-PAGE).
[0225] In a preferred embodiment, such as by residual activity and denaturation temperature T d The provided thermal properties (e.g., heating stability, temperature stability, thermal stability, steam stability, and / or granulation stability) or other parameters of the proteases of the present invention are higher than corresponding values (e.g., the residual activity or T of the proteases of SEQ ID NO:5 and / or SEQ ID NO:14). d More preferably, it is at least 101%, or at least 102%, 103%, 104%, 105%, 106%, 107%, 108%, 109%, or at least 110%. Even more preferably, the parameters of the protease of the present invention (such as residual activity or T) d The value is at least 120%, 130%, 140%, 150%, 160%, 170%, 180%, or at least 190% of the value of the protease in SEQ ID NO:5 and / or SEQ ID NO:14 and / or SEQ ID NO:20.
[0226] In yet another specific embodiment, the heat-stable protease of the present invention has a melting temperature T of at least 50°C. m (or denaturation temperature T) d The value of T was determined by differential scanning calorimetry (DSC) as described in Example 5 (i.e., at 20 mM sodium acetate, pH 4.0). In yet another specific embodiment, the T... mIt is at least 51℃, 52℃, 53℃, 54℃, 55℃, 56℃, 57℃, 58℃, 59℃, 60℃, 61℃, 62℃, 63℃, 64℃, 65℃, 66℃, 67℃, 68℃, 69℃, 70℃, 71℃, 72℃, 73℃, 74℃, 75℃, 76℃, 77℃, 78℃, 79℃, 80℃, 81℃, 82℃, 83℃, 84℃, 85℃, 86℃, 87℃, 88℃, 89℃, 90℃, 91℃, 92℃, 93℃, 94℃, 95℃, 96℃, 97℃, 98℃, 99℃ or at least 100℃.
[0227] Steam stability
[0228] Steam stability can be determined, as described in Example 6, by determining the residual activity of the protease molecules after steam treatment at 85°C or 90°C for a short time.
[0229] Granulation stability
[0230] Granulation stability can be determined, as described in Example 7, by using enzyme granules premixed with the feed. The feed is conditioned to 95°C using steam in the mixer. After conditioning, the feed is pressurized into pellets and residual activity is determined.
[0231] Sources of peptides with protease activity
[0232] The protease-active polypeptides according to the invention can be obtained from any genus of microorganisms. For the purposes of this invention, as used herein in conjunction with the given sources, the term "obtained from" shall mean that the polypeptide encoded by the polynucleotide is produced by that source or by a strain in which a polynucleotide from that source has been inserted. In one aspect, the polypeptide obtained from a given source is secreted extracellularly.
[0233] The polypeptide can be a bacterial polypeptide. For example, the polypeptide can be a polypeptide with protease activity derived from a Gram-positive bacterium such as Actinobacteria or a Gram-negative bacterium such as Proteobacteria.
[0234] In one instance, the polypeptide is a protease from bacteria of the class Actinomycetes, such as those from the order Micrococciles, or from the family Mesocystaceae, or from the genus *Hypertricis*, *Terracoccus*, or *Knoellia*.
[0235] The strains of these taxa are readily available to the public at many culture collections, such as the American Type Culture Collection (ATCC), the German Microbial and Cell Culture Collection (DSM), the Culture Collection of Fungi (CBS), and the Northern Research Center of the Patent Culture Collection of the Agricultural Research Institute (NRRL).
[0236] The probes described above can be used to identify and obtain the polypeptide from microorganisms isolated from other sources, including those from nature (e.g., soil, compost, water, etc.). Techniques for isolating microorganisms from natural habitats are well known in the art. The polynucleotide encoding the polypeptide can then be obtained by similarly screening the genome or cDNA library of another microorganism or a mixed DNA sample. Once a polynucleotide encoding a polypeptide is detected with this or these probes, the polynucleotide can be isolated or cloned using techniques well known to those skilled in the art (see, for example, Sambrook et al., 1989, above).
[0237] Polynucleotides
[0238] The present invention also relates to polynucleotides encoding the polypeptides of the present invention, as described herein. In one embodiment, the polynucleotide encoding the polypeptides of the present invention has been isolated.
[0239] Techniques for isolating or cloning polynucleotides are known in the art and include isolation from genomic DNA or cDNA, or combinations thereof. Polynucleotides can be cloned from genomic DNA, for example, by detecting cloned DNA fragments with shared structural features using well-known polymerase chain reaction (PCR) or antibody screening of expression libraries. See, for example, Innis et al., 1990, PCR: A Guide to Methods and Application, Academic Press, New York. Other nucleic acid amplification procedures can be used, such as ligase chain reaction (LCR), ligation-activated transcription (LAT), and polynucleotide-based amplification (NASBA). Polynucleotides can be cloned from strains of *Hypertricis*, *Terracoccus*, or *Knoellia*, or from related organisms of the *Micrococcus* genus, and therefore, for example, can be allelic or species variants of the polypeptide coding region of the polynucleotide.
[0240] Nucleic acid constructs
[0241] The present invention also relates to nucleic acid constructs comprising polynucleotides of the present invention operably linked to one or more control sequences, wherein the control sequences guide the expression of coding sequences in suitable host cells under conditions compatible with the control sequences.
[0242] The polynucleotide can be manipulated in many ways to facilitate polypeptide expression. Depending on the expression vector, manipulation of the polynucleotide prior to insertion into the vector may be desirable or necessary. Techniques for modifying polynucleotides using recombinant DNA methods are well known in the art.
[0243] The control sequence can be a promoter, i.e., a polynucleotide recognized by the host cell to express a polynucleotide encoding the polypeptide of the present invention. The promoter contains a transcriptional control sequence that mediates polypeptide expression. The promoter can be any polynucleotide exhibiting transcriptional activity in the host cell, including mutant, truncated, and heterozygous promoters, and can be obtained from a gene encoding an extracellular or intracellular polypeptide that is homologous or heterologous to that of the host cell.
[0244] Examples of suitable promoters for directing the transcription of the nucleic acid constructs of this invention in bacterial host cells are promoters obtained from the following genes: Bacillus amyloliquefaciens α-amylase gene (amyQ), Bacillus licheniformis α-amylase gene (amyL), Bacillus licheniformis penicillinase gene (penP), Bacillus thermophilus maltose amylase gene (amyM), Bacillus subtilis fructan sucrase gene (sacB), Bacillus subtilis xylA and xylB genes, Bacillus thuringiensis cryIIIA gene (Agaisse and Lereclus, 1994, Molecular Microbiology). Microbiology 13:97-107), Escherichia coli lac operon, Escherichia coli trc promoter (Egon et al., 1988, Gene 69:301-315), Streptomyces agar hydrolase gene (dagA), and prokaryotic β-lactamase gene (Villa-Kamaroff et al., 1978, Proc. Natl. Acad. Sci. USA 75:3727-3731) and tac promoter (DeBoer et al., 1983, Proc. Natl. Acad. Sci. USA 80:21-25). Other promoters are described in Gilbert et al., 1980, Scientific American 242:74-94, “Useful proteins from recombinant bacteria”; and in Sambrook et al., 1989, ibid. Examples of tandem promoters are disclosed in WO 99 / 43835.
[0245] Examples of suitable promoters for guiding the transcription of the nucleic acid constructs of this invention in filamentous fungal host cells are promoters derived from the following genes: Aspergillus nidulans acetamase, Aspergillus niger neutral α-amylase, Aspergillus niger acid-stable α-amylase, Aspergillus niger or Aspergillus awamori glucoamylase (glaA), Aspergillus oryzae TAKA amylase, Aspergillus oryzae alkaline protease, Aspergillus oryzae triose phosphate isomerase, Fusarium oxysporum trypsin-like protease (WO 96 / 00787), Fusarium moniliforme amyloglucosidase (WO 00 / 56900), Fusarium moniliforme Daria (WO 00 / 56900), Fusarium moniliforme Quinn (WO 00 / 56900). 00 / 56900), *Rhizopus mirtii* lipase, *Rhizopus mirtii* aspartic protease, *Trichoderma reesei* β-glucosidase, *Trichoderma reesei* cellobiose hydrolase I, *Trichoderma reesei* cellobiose hydrolase II, *Trichoderma reesei* endoglucanase I, *Trichoderma reesei* endoglucanase II, *Trichoderma reesei* endoglucanase III, *Trichoderma reesei* endoglucanase V, *Trichoderma reesei* xylanase I, *Trichoderma reesei* xylanase II, *Trichoderma reesei* xylanase III, *Trichoderma reesei* β-xylosidase, and *Trichoderma reesei* translational elongation factor. The promoter, together with the NA2-tpi promoter (a modified promoter from an Aspergillus gene encoding neutral α-amylase, wherein the untranslated pre-progenitor has been replaced with an untranslated pre-progenitor from an Aspergillus gene encoding triose phosphate isomerase; non-limiting examples include a modified promoter from an Aspergillus niger gene encoding neutral α-amylase, wherein the untranslated pre-progenitor has been replaced with an untranslated pre-progenitor from an Aspergillus nidulans or Aspergillus oryzae gene encoding triose phosphate isomerase), and its mutant, truncated, and heterozygous promoters. Other promoters are described in U.S. Patent No. 6,011,147.
[0246] In yeast hosts, useful promoters are derived from genes targeting the following: *Saccharomyces cerevisiae* enolase (ENO-1), *Saccharomyces cerevisiae* galactokinase (GAL1), *Saccharomyces cerevisiae* alcohol dehydrogenase / glyceraldehyde-3-phosphate dehydrogenase (ADH1, ADH2 / GAP), *Saccharomyces cerevisiae* triose phosphate isomerase (TPI), *Saccharomyces cerevisiae* metallothionein (CUP1), and *Saccharomyces cerevisiae* 3-phosphate glycerate kinase. Other useful promoters in yeast host cells are described in Romanos et al., 1992, Yeast 8:423-488.
[0247] The control sequence can also be a transcription terminator recognized by the host cell to terminate transcription. The terminator is operatively linked to the 3' end of the polynucleotide encoding the polypeptide. Any terminator that is functional in the host cell can be used in this invention.
[0248] The preferred terminator for bacterial host cells is obtained from genes targeting the following: Bacillus clausti alkaline protease (aprH), Bacillus licheniformis α-amylase (amyL), and Escherichia coli ribosomal RNA (rrnB).
[0249] Preferred terminators for filamentous fungal host cells are derived from the genes of: Aspergillus nidulans acetamase, Aspergillus nidulans o-aminobenzoic acid synthase, Aspergillus niger glucosylamylase, Aspergillus niger α-glucosidase, Aspergillus oryzae TAKA amylase, Fusarium oxysporum trypsin-like protease, Trichoderma reesei β-glucosidase, Trichoderma reesei cellobiose hydrolase I, Trichoderma reesei cellobiose hydrolase II, Trichoderma reesei endoglucanase I, Trichoderma reesei endoglucanase II, Trichoderma reesei endoglucanase III, Trichoderma reesei endoglucanase V, Trichoderma reesei xylanase I, Trichoderma reesei xylanase II, Trichoderma reesei xylanase III, Trichoderma reesei β-xylosidase, and Trichoderma reesei translation elongation factor.
[0250] Preferred terminators for yeast host cells are derived from the genes of *Saccharomyces cerevisiae* enolase, *Saccharomyces cerevisiae* cytochrome C (CYC1), and *Saccharomyces cerevisiae* glyceraldehyde-3-phosphate dehydrogenase. Other useful terminators for yeast host cells are described above in Romanos et al., 1992.
[0251] The control sequence can also be a stabilizer region of mRNA downstream of the promoter and upstream of the gene coding sequence, which increases the expression of the gene.
[0252] Examples of suitable mRNA stable regions were obtained from the following: Bacillus thuringiensis cryIIIA gene (WO 94 / 25612) and Bacillus subtilis SP82 gene (Hue et al., 1995, Journal of Bacteriology 177:3465-3471).
[0253] This control sequence can also be a pre-translation, which is the untranslated region of an mRNA important for translation in the host cell. This pre-translation is operatively linked to the 5' end of the polynucleotide encoding the polypeptide. Any pre-translation that is functional in the host cell can be used.
[0254] Preferred precursors for use in filamentous fungal host cells were obtained from the genes of Aspergillus oryzae TAKA amylase and Aspergillus nidulans triose phosphate isomerase.
[0255] Suitable precursors for yeast host cells were obtained from the genes of *Saccharomyces cerevisiae* enolase (ENO-1), *Saccharomyces cerevisiae* 3-phosphoglycerate kinase, *Saccharomyces cerevisiae* gluten-factor, and *Saccharomyces cerevisiae* alcohol dehydrogenase / glyceraldehyde-3-phosphate dehydrogenase (ADH2 / GAP).
[0256] The control sequence can also be a polyadenylation sequence, a signaling sequence operatively linked to the 3' end of a polynucleotide and recognized by the host cell during transcription as an addition of polyadenylate residues to the transcribed mRNA. Any polyadenylation sequence that functions in the host cell can be used.
[0257] Preferred polyadenylated sequences for use in filamentous fungal host cells were obtained from the genes of Aspergillus nidulans anthranilate synthase, Aspergillus niger glucosidase, Aspergillus niger α-glucosidase, Aspergillus oryzae TAKA amylase, and Fusarium oxysporum trypsin-like protease.
[0258] The polyadenylated sequences useful for yeast host cells are described in Guo and Sherman, 1995, Molecular Cellular Biology, 15:5983-5990.
[0259] The control sequence can also be a signal peptide coding region that encodes a signal peptide linked to the N-terminus of a polypeptide and guides the polypeptide into the cell's secretion pathway. The 5' end of the polynucleotide coding sequence can inherently contain a signal peptide coding sequence naturally linked to a segment of the coding sequence of the polypeptide within the translation reading frame. Alternatively, the 5' end of the coding sequence can contain a foreign signal peptide coding sequence relative to the coding sequence. In cases where the coding sequence does not naturally contain a signal peptide coding sequence, a foreign signal peptide coding sequence may be required. Alternatively, a foreign signal peptide coding sequence can simply replace the natural signal peptide coding sequence to enhance polypeptide secretion. However, any signal peptide coding sequence that guides the secretion pathway of the expressed polypeptide into the host cell can be used.
[0260] Effective signal peptide coding sequences for bacterial host cells are obtained from the genes of *Bacillus NCIB 11837* maltose amylase, *Bacillus licheniformis* subtilis protease, *Bacillus licheniformis* calc-lactamase, *Bacillus thermophilus* glutamyl-amylase, *Bacillus thermophilus* neutral proteases (nprT, nprS, nprM), and *Bacillus subtilis* prsA. Other signal sequences are described by Simonen and Palva, 1993, *Microbiological Reviews* 57:109-137.
[0261] The effective signal peptide coding sequences for filamentous fungal host cells are obtained from the genes of Aspergillus niger neutral amylase, Aspergillus niger glucosylase, Aspergillus oryzae TAKA amylase, Aspergillus oryzae cellulase, Aspergillus oryzae endoglucanase V, Aspergillus pubescens lipase, and Rhizopus oryzae aspartic protease.
[0262] Useful signal peptides for yeast host cells were obtained from the genes of Saccharomyces cerevisiae α-factor and Saccharomyces cerevisiae invertase. Other useful signal peptide coding sequences were described by Romanos et al. (1992, above).
[0263] The control sequence can also be a propeptide-coding sequence encoding the propeptide located at the N-terminus of the polypeptide. The resulting polypeptide is called a proenzyme or propeptide progenitor (or, in some cases, a zymogen). The propeptide progenitor is usually inactive and can be converted into an active polypeptide by catalytic cleavage or autocatalytic cleavage of the propeptide progenitor. The propeptide-coding sequence can be obtained from the genes of Bacillus subtilis alkaline protease (aprE), Bacillus subtilis neutral protease (nprT), Thermophilus laccase (WO 95 / 33836), Rhizopus oryzae aspartic protease, and Saccharomyces cerevisiae α-factor.
[0264] In the presence of both the signal peptide sequence and the propeptide sequence, the propeptide sequence is positioned immediately adjacent to the N-terminus of the polypeptide, and the signal peptide sequence is positioned immediately adjacent to the N-terminus of the propeptide sequence.
[0265] It may also be desirable to add regulatory sequences that regulate the expression of polypeptides relative to the growth of the host cell. Examples of regulatory sequences are those that cause gene expression to be turned on or off in response to chemical or physical stimuli, including the presence of regulatory compounds. Regulatory sequences in prokaryotic systems include the lac, tac, and trp operon systems. In yeast, the ADH2 or GAL1 systems can be used. In filamentous fungi, the Aspergillus niger glucosyl amylase promoter, the Aspergillus oryzae TAKA α-amylase promoter and the Aspergillus oryzae glucosyl amylase promoter, the Trichoderma reesei cellobiase I promoter and the Trichoderma reesei cellobiase II promoter can be used. Other examples of regulatory sequences are those that allow gene amplification. In eukaryotic systems, these regulatory sequences include dihydrofolate reductase genes amplified in the presence of methotrexate and metallothionein genes amplified with heavy metals. In these cases, the polynucleotide encoding the polypeptide will be operatively linked to the regulatory sequence.
[0266] expression carrier
[0267] The present invention also relates to recombinant expression vectors comprising the polynucleotide of the present invention, a promoter, and transcription and translation termination signals. Different nucleotides and control sequences can be linked together to produce a recombinant expression vector, which may include one or more convenient restriction enzyme sites to allow insertion or substitution of the polynucleotide encoding the polypeptide at these sites. Alternatively, the polynucleotide can be expressed by inserting the polynucleotide or a nucleic acid construct comprising the polynucleotide into a suitable vector for expression. In producing the expression vector, the coding sequence is located within the vector, such that the coding sequence is operatively linked to the suitable control sequence for expression.
[0268] Recombinant expression vectors can be any vector (e.g., plasmids or viruses) that can readily undergo recombinant DNA procedures and induce polynucleotide expression. The choice of vector will typically depend on its compatibility with the host cell to which it will be introduced. The vector can be a linear or closed circular plasmid.
[0269] The vector can be a self-replicating vector, that is, a vector existing as an extrachromosomal entity whose replication is independent of chromosome replication, such as a plasmid, extrachromosomal element, microchromosome, or artificial chromosome. The vector can contain any elements necessary to ensure self-replication. Alternatively, the vector can be one that, when introduced into the host cell, is integrated into the genome and replicates along with one or more chromosomes in which it has been integrated. Furthermore, a single vector or plasmid, or two or more vectors or plasmids (which together contain the total DNA of the genome to be introduced into the host cell), or transposons can be used.
[0270] The vector preferably contains one or more selective markers that allow for convenient selection of cells such as transformed cells, transfected cells, and transduced cells. A selective marker is a gene whose product provides resistance to biocides or viruses, heavy metal resistance, or auxotrophic prototrophs, etc.
[0271] Examples of bacterial selective markers include the dal gene in Bacillus licheniformis or Bacillus subtilis, or markers that confer antibiotic resistance (such as resistance to ampicillin, chloramphenicol, kanamycin, neomycin, spectinomycin, or tetracycline). Suitable markers for use in yeast host cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2, MET3, TRP1, and URA3. Selective markers for use in filamentous fungal host cells include, but are not limited to, adeA (phosphogluconoylaminoimidazolium-succinate carboxylamine synthase), adeB (phosphogluconoylaminoimidazolium synthase), amdS (acetamipase), argB (ornithine carbamoyltransferase), bar (glufosinate acetyltransferase), hph (hygromycin phosphotransferase), niaD (nitrate reductase), pyrG (orotate nucleoside-5'-phosphate decarboxylase), sC (adenosyl sulfate transtransferase), and trpC (o-aminobenzoic acid synthase), along with their equivalents. The amdS and pyrG genes of *Aspergillus nidus* or *Aspergillus oryzae*, and the bar gene of *Streptomyces hygroscopicus* are preferably used in *Aspergillus* cells. In *Trichoderma* cells, the adeA, adeB, amdS, hph, and pyrG genes are preferred.
[0272] Selective labeling can be a biselective labeling system as described in WO 2010 / 039889. In one aspect, the biselective labeling is the hph-tk biselective labeling system.
[0273] The vector preferably contains one or more elements that allow the vector to integrate into the host cell’s genome or to replicate autonomously in the cell independently of the genome.
[0274] For integration into the host cell genome, the vector can rely on a polynucleotide sequence encoding the polypeptide or any other element of the vector for integration into the genome via homologous or non-homologous recombination. Alternatively, the vector can contain additional polynucleotides to guide integration into one or more precise locations on one or more chromosomes of the host cell genome via homologous recombination. To increase the likelihood of integration at precise locations, these integrative elements should contain a sufficient number of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000 base pairs, and 800 to 10,000 base pairs, that have high sequence identity with the corresponding target sequence to increase the likelihood of homologous recombination. These integrative elements can be any sequence homologous to the target sequence in the host cell genome. Furthermore, these integrative elements can be non-coding or coding polynucleotides. On the other hand, the vector can integrate into the host cell genome via non-homologous recombination.
[0275] For autonomous replication, the vector may further include an origin of replication that enables the vector to replicate autonomously in the host cell in question. The origin of replication can be any plasmid replicon that mediates autonomous replication and functions within the cell. The terms "origin of replication" or "plasmid replicon" refer to the polynucleotide that enables a plasmid or vector to replicate in vivo.
[0276] Examples of bacterial origins of replication are the origins of replication of plasmids pBR322, pUC19, pACYC177, and pACYC184, which allow replication in Escherichia coli, and the origins of replication of plasmids pUB110, pE194, pTA1060, and pAMβ1, which allow replication in Bacillus.
[0277] Examples of replication origins used in yeast host cells include the 2-micron replication origin, ARS1, ARS4, a combination of ARS1 and CEN3, and a combination of ARS4 and CEN6.
[0278] Examples of useful origins of replication in filamentous fungal cells are AMA1 and ANS1 (Gems et al., 1991, Gene 98:61-67; Cullen et al., 1987, Nucleic Acids Res. 15:9163-9175; WO 00 / 24883). The AMA1 gene can be isolated and plasmids or vectors containing the gene can be constructed according to the methods disclosed in WO 00 / 24883.
[0279] One or more copies of the polynucleotide of the present invention can be inserted into a host cell to increase polypeptide production. An increased copy number of the polynucleotide can be obtained by integrating at least one additional copy of the sequence into the host cell genome or by including an amplifiable selective marker gene along with the polynucleotide, wherein cells containing an amplified copy of the selective marker gene, and thus additional copies of the polynucleotide, can be selected by culturing cells in the presence of a suitable selective reagent.
[0280] The procedures for connecting the elements described above to construct the recombinant expression vector of the present invention are well known to those skilled in the art (see, for example, Sambrook et al., 1989, ibid.).
[0281] host cells
[0282] This invention also relates to recombinant host cells containing polynucleotides of the invention operably linked to one or more control sequences that direct the production of polypeptides of the invention. A construct or vector comprising the polynucleotide is introduced into the host cell such that the construct or vector is maintained as a chromosomal integrase or as an autonomously replicating extrachromosomal vector, as previously described. The term "host cell" encompasses any progeny of a parent cell that differs from the parent cell due to mutations occurring during replication. The selection of the host cell depends largely on the gene encoding the polypeptide and its origin.
[0283] The host cell can be any cell that has been used to recombine and generate the polypeptide of the present invention, such as a prokaryotic cell or a eukaryotic cell.
[0284] Prokaryotic host cells can be any Gram-positive or Gram-negative bacteria. Gram-positive bacteria include, but are not limited to: Bacillus, Clostridium, Enterococcus, Bacillus aeruginosa, Lactobacillus, Lactococcus, Marine Bacillus, Staphylococcus, Streptococcus, and Streptomyces. Gram-negative bacteria include, but are not limited to: Campylobacter, Escherichia coli, Flavobacterium, Fusobacterium, Helicobacter, Coliform, Neisseria, Pseudomonas, Salmonella, and Ureaplasma.
[0285] The bacterial host cell can be any Bacillus genus cell, including but not limited to: Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus brevis, Bacillus circulans, Bacillus croceus, Bacillus coagulans, Bacillus sclerosus, Bacillus splenium, Bacillus stenosis, Bacillus licheniformis, Bacillus megaterium, Bacillus brevis, Bacillus thermophilus, Bacillus subtilis, and Bacillus thuringiensis cells.
[0286] The bacterial host cell can also be any streptococcal cell, including but not limited to: Streptococcus equina, Streptococcus pyogenes, Streptococcus mammae, and Streptococcus equine subsp. veterinaryis.
[0287] The bacterial host cell can also be any Streptomyces cell, including but not limited to: non-chromogenic Streptomyces, insecticidal Streptomyces, sky blue Streptomyces, gray Streptomyces and light blue Streptomyces cells.
[0288] DNA can be introduced into Bacillus cells via the following methods: protoplast transformation (see, for example, Chang and Cohen, 1979, Molecular Genetics and Genomics, 168:111-115), and competent cell transformation (see, for example, Young and Spizizen, 1961, Journal of Bacteriology, 81:823-829; or Dubnau and David Dubnau). Davidoff-Abelson, 1971, Journal of Molecular Biology 56:209-221, electroporation (see, for example, Shigekawa and Dower, 1988, Biotechniques 6:742-751), or conjugation (see, for example, Koehler and Thorne, 1987, Journal of Bacteriology 169:5271-5278). DNA can be introduced into E. coli cells via protoplast transformation (see, for example, Hanahan, 1983, Journal of Molecular Biology 166:557-580) or electroporation (see, for example, Dower et al., 1988, Nucleic Acids Res. 16:6127-6145). DNA can be introduced into Streptomyces cells via protoplast transformation, electroporation (see, for example, Gong et al., 2004, Folia Microbiol. (Praha) 49:399-405), conjugation (see, for example, Mazodier et al., 1989, Journal of Bacteriol. 171:3583-3585), or transduction (see, for example, Burke et al., 2001, Proceedings of the National Academy of Sciences of the United States of America (Proc. Natl. Acad. Sci. USA) 98:6289-6294). DNA can be introduced into Pseudomonas cells by electroporation (see, for example, Choi et al., 2006, Journal of Microbiological Methods, 64:391-397) or conjugation (see, for example, Pinedo and Smets, 2005, Appl. Environ. Microbiol., 71:51-57).Introducing DNA into Streptococcus cells can be achieved through: native competent cells (see, e.g., Perry and Kuramitsu, 1981, Infect. Immun. 32:1295-1297), protoplast transformation (see, e.g., Catt and Jollick, 1991, Microbios. 68:189-207), electroporation (see, e.g., Buckley et al., 1999, Applied and Environmental Microbiology 65:3800-3804), or conjugation (see, e.g., Clewell, 1981, Microbiol. Rev. 45:409-436). However, any method known in the art for introducing DNA into host cells can be used.
[0289] The host cell can also be a eukaryotic cell, such as a mammalian, insect, plant, or fungal cell.
[0290] The host cell can be a fungal cell. As used herein, “fungus” includes Ascomycota, Basidiomycota, Chytridiomycota, Zygomycota, Oomycota, and all mitotic fungi (as defined by Hawksworth et al., in: Dictionary of the Fungi, Ainsworth and Bisby, 8th ed., 1995, CAB International, University Press, Cambridge, UK).
[0291] The host cell for fungi can be a yeast cell. As used herein, "yeast" includes ascosporogenous yeast (Endomycetales), basidiosporogenous yeast, and yeasts belonging to the class Fungi Imperfecti (Blastomycetes). Since yeast classification may change in the future, for the purposes of this invention, yeast should be defined as described in *Biology and Activities of Yeast* (Skinner, Passmore, and Davenport, eds., Soc. App. Bacteriol. Symposium Series No. 9, 1980).
[0292] Yeast host cells can be cells from the genera *Candida*, *Hansenula*, *Kluyver*, *Pichia*, *Saccharomyces*, *Saccharomyces*, or *Yarrowia*, such as *Kluyveromyces lactis*, *Kluyveria*, *Saccharomyces cerevisiae*, *Saccharomyces sacchari*, *Saccharomyces davidiana*, *Saccharomyces douglas*, *Kluyver*, *Nordiya*, *Ovoyces*, or *Yarrowia lipolytica*.
[0293] The host cell of this fungus can be a filamentous fungal cell. "Filamentous fungi" includes all filamentous forms of the subphylum Eumycota and Oomycota (as defined above by Hawkesworth et al., 1995). Filamentous fungi are typically characterized by a hyphal wall composed of chitin, cellulose, glucan, chitosan, mannan, and other complex polysaccharides. Vegetative growth occurs through hyphal extension, and carbon metabolism is obligate aerobic. In contrast, yeast (such as Saccharomyces cerevisiae) grows vegetatively through budding of single-celled cells, and carbon metabolism can be fermentation.
[0294] The host cells of filamentous fungi can be cells from genera such as *Apertoire*, *Aspergillus*, *Bjerkandera*, *Pseudomonas*, *Aureospora*, *Coprinus*, *Coriolus*, *Cryptococcus*, *Filibasidium*, *Fusarium*, *Pyrophyllus*, *Pleurotus*, *Mucor*, *Pyrophyllus*, *Pleurotus ... or *Trichoderma*.
[0295] For example, the host cells of filamentous fungi can be *Aspergillus amblymorii*, *Aspergillus sulphureus*, *Aspergillus fumigatus*, *Aspergillus japonicus*, *Aspergillus nidus*, *Aspergillus oryzae*, *Bjerkandera adusta*, *Ceriporiopsis saneirina*, *Ceriporiopsis caregiea*, *Ceriporiopsis gilvescens*, *Ceriporiopsis pannocinta*, *Ceriporiopsis rivulosa*, *Ceriporiopsis subrufa*, *Ceriporiopsis subvermispora*, *Chrysosporium inops*, *Chrysosporium lucknowense*, and *Chrysosporium foetida*. merdarium), rent spores, Queensland golden spores (Chrysosporium queenslandicum), tropical golden spores, brown golden spores (Chrysosporium zonatum), gray-capped coprinus (Coprinus cinereus), hairy-skinned spores (Coriolushirsutus), rod-shaped spores (Fusarium), cereal spores (Fusarium), kuweiss spores (Fusarium), large-knife spores (Fusarium), grass spores (Fusarium), red spores (Fusarium), heterospores (Fusarium), albinofuss spores (Fusarium), acuminata spores (Fusarium), multibranched spores (Fusarium), pink spores (Fusarium), elderberry spores (Fusarium), skin-colored spores (Fusarium), pseudo-clastic spores (Fusarium), sulfur spores (Fusarium), round spores (Fusarium), pseudo-filamentous spores (Fusarium), patchy spores (Fusarium), specific humic molds (Fusarium), soft-haired humic molds (Fusarium), rice black molds (Mucor), thermophilic filamentous molds (Fusarium), rough spores (Nephrolepis), purpuric molds (Penicillium), Phanerochaete chrysosporium (Phanerochaete chrysosporium), radiata (Phlebia radiata), Pleurotus eryngii (Pleurotus) eryngii), terrestrial clostridium, Trametes villosa, Trametes versicolor, Trichoderma harzianum, Trichoderma corningensis, Trichoderma longibranchii, Trichoderma reesei, or green Trichoderma cells.
[0296] Fungal cells can be transformed through a process involving protoplast formation, protoplast transformation, and cell wall regeneration in a manner known per se. Suitable procedures for transforming Aspergillus and Trichoderma host cells are described in EP 238023 and Yelton et al., 1984, Proceedings of the National Academy of Sciences (Proc. Natl. Acad. Sci. USA) 81:1470-1474 and Christensen et al., 1988, Bio / Technology 6:1419-1422. Suitable methods for transforming Fusarium species are described in Maladier et al., 1989, Gene 78:147-156 and WO 96 / 00787. Yeast can be transformed using procedures described in the following literature: Becker and Guarente, in Abelson, JN and Simon, MI (eds.), Guide to Yeast Genetics and Molecular Biology, Methods in Enzymology, Vol. 194, pp. 182-187, Academic Press, Inc., New York; Ito et al., 1983, Journal of Bacteriology, 153:163; and Hinnen et al., 1978, Proceedings of the National Academy of Sciences of the United States of America, 75:1920.
[0297] Method of generation
[0298] The present invention also relates to a method for producing the polypeptide of the invention, comprising (a) culturing cells under conditions favorable to the production of the polypeptide, the cells producing the polypeptide in their wild-type form; (b) optionally isolating the polypeptide; and (c) recovering the polypeptide. In one aspect, the cell is an Alternaria haematomycete cell. In another aspect, the cell is an Alternaria haematomycete HTCC2649 cell. In another aspect, the cell is a Terracoccus cell. In another aspect, the cell is a Terracoccus sp. 273MFTsu3.1 cell. In another aspect, the cell is a Knoellia cell. In another aspect, the cell is a Knoellia flavus cell.
[0299] The present invention also relates to a method for producing the polypeptide of the present invention, the method comprising (a) culturing a recombinant Bacillus spp. expression host cell containing a polynucleotide encoding the polypeptide of the present invention, the polynucleotide being operatively linked to one or more control sequences that direct the production of the polypeptide under conditions favorable to the production of the polypeptide; (b) optionally isolating the polypeptide; and (c) recovering the polypeptide.
[0300] In one embodiment, the host cell for the Bacillus expression is selected from the following list, which consists of the following items: Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus brevis, Bacillus circulans, Bacillus clausii, Bacillus coagulans, Bacillus firmus, Geobacillus stearothermophilus, Bacillus lautus, Bacillus lentus, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus, Bacillus stearothermophilus, and Bacillus subtilis. Bacillus subtilis and Bacillus thuringiensis. In a preferred embodiment, the host cell for expression of the Bacillus genus is selected from the following list, which consists of the following items: Bacillus licheniformis, Bacillus amyloliquefaciens, and Bacillus subtilis.
[0301] These host cells are cultured in a nutrient medium suitable for producing the polypeptide using methods known in the art. For example, cells can be cultured by shake flask culture or by small-scale or large-scale fermentation (including continuous, batch, fed-batch, or solid-state fermentation) in a laboratory or industrial fermenter, said culture being carried out in a suitable medium and under conditions that allow for the expression and / or isolation of the polypeptide. This culture occurs using procedures known in the art in a suitable nutrient medium comprising carbon and nitrogen sources and inorganic salts. Suitable media are available from commercial suppliers or can be prepared according to publicly available compositions (e.g., in the catalogue of the U.S. Center for Type Culture Collection). If the polypeptide is secreted into the nutrient medium, it can be recovered directly from the medium. If the polypeptide is not secreted, it can be recovered from cell lysates.
[0302] The peptide can be detected using methods known in the art that are specific to these peptides. These detection methods include, but are not limited to, the use of specific antibodies, the formation of enzyme products, or the disappearance of enzyme substrates. For example, enzyme assays can be used to determine the activity of the peptide.
[0303] The polypeptide can be recovered using methods known in the art. For example, the polypeptide can be recovered from the nutrient medium through conventional procedures, including but not limited to, collection, centrifugation, filtration, extraction, spray drying, evaporation, or precipitation. In one aspect, fermentation broth containing the polypeptide is recovered.
[0304] Peptides can be purified by a variety of methods known in the art, including but not limited to chromatography (e.g., ion exchange chromatography, affinity chromatography, hydrophobic chromatography, focusing chromatography, and size exclusion chromatography), electrophoresis (e.g., preparative isoelectric focusing), differential dissolution (e.g., ammonium sulfate precipitation), SDS-PAGE, or extraction (see, for example, Protein Purification, edited by Janson and Ryden, VCH Publishing, New York, 1989) to obtain substantially pure peptides.
[0305] In terms of alternatives, the peptide is not recycled; instead, the host cell of the present invention expressing the peptide is used as the source of the peptide.
[0306] plant
[0307] This invention also relates to isolated plants, such as transgenic plants, plant parts, or plant cells, that include the polypeptides of this invention, thereby expressing and producing a recoverable amount of the polypeptide or domain. The polypeptide or domain can be recovered from the plant or plant part. Alternatively, the plant or plant part including the polypeptide or domain can be used as is to improve the quality of food or feed, such as improving nutritional value, palatability, and rheological properties, or disrupting anti-nutritional factors.
[0308] Genetically modified plants can be dicotyledonous (dicotyledonous plants) or monocotyledonous (monocotyledonous plants). Examples of monocotyledonous plants are grasses, such as meadow grass (bluegrass, Kentucky bluegrass); forage grasses, such as fescue (Festuca) and ryegrass (Lolium); temperate grasses, such as creeping bentgrass (Agrostis); and cereals, such as wheat, oats, rye, barley, rice, sorghum, and corn.
[0309] Examples of dicotyledonous plants include tobacco, legumes (such as lupins, potatoes, sugar beets, peas, beans, and soybeans), and cruciferous plants (such as cauliflower, rapeseed, and the closely related model organism Arabidopsis thaliana).
[0310] Examples of plant parts include stems, callus, leaves, roots, fruits, seeds, and tubers, as well as individual tissues that include these parts, such as epidermis, mesophyll, parenchyma, vascular tissue, and meristematic tissue.
[0311] Plant cells and specific plant cell compartments (such as chloroplasts, apoplasts, mitochondria, vacuoles, peroxisomes, and cytoplasm) are also considered plant parts.
[0312] Also included within the scope of this invention are such plants, plant parts, and offspring of plant cells.

[0315] Fermentation broth preparations or cell compositions
[0316] The present invention also relates to fermentation broth formulations or cell compositions comprising the polypeptides of the present invention. The fermentation broth product further comprises additional components used in the fermentation process, such as cells (including host cells containing genes encoding the polypeptides of the present invention, which are used to produce the polypeptides of interest), cell debris, biomass, fermentation medium, and / or fermentation products. In some embodiments, the composition is a cell-killing whole culture medium comprising one or more organic acids, killed cells and / or cell debris, and a culture medium.
[0317] As used herein, the term "fermentation broth" refers to a preparation produced by cell fermentation that undergoes little or no recovery and / or purification. For example, fermentation broth is produced when a microbial culture is incubated to saturation under carbon-limited conditions that allow protein synthesis (e.g., expression by enzymes of the host cell) and secretion of proteins into the cell culture medium. Fermentation broth may contain unfractionated or fractionated contents of the fermentation material obtained at the end of fermentation. Typically, fermentation broth is unfractionated and includes used culture medium and cell debris remaining after, for example, removal of microbial cells (e.g., filamentous fungal cells) by centrifugation. In some embodiments, fermentation broth contains used cell culture medium, extracellular enzymes, and viable and / or non-viable microbial cells.
[0318] In one embodiment, the fermentation broth formulation and cell composition comprise a first organic acid component (comprising at least one 1-5 carbon organic acid and / or its salt) and a second organic acid component (comprising at least one 6- or more carbon organic acid and / or its salt). In a specific embodiment, the first organic acid component is acetic acid, formic acid, propionic acid, its salt, or a mixture of two or more of the foregoing; and the second organic acid component is benzoic acid, cyclohexanecarboxylic acid, 4-methylvaleric acid, phenylacetic acid, its salt, or a mixture of two or more of the foregoing.
[0319] In one aspect, the composition comprises one or more organic acids and optionally further comprises killed cells and / or cell debris. In one embodiment, these killed cells and / or cell debris are removed from the cell-killing whole culture medium to provide a composition free of these components.
[0320] These fermentation broth formulations or cell compositions may further include preservatives and / or antimicrobial (e.g., bacteriostatic) agents, including but not limited to sorbitol, sodium chloride, potassium sorbate, and other agents known in the art.
[0321] The cell-killing whole culture or composition may contain the ungraded contents of the fermentation material obtained at the end of fermentation. Typically, the cell-killing whole culture or composition includes used culture medium and cell debris present after microbial cells (e.g., filamentous fungal cells) have been grown to saturation and incubated under carbon-limited conditions to allow protein synthesis. In some embodiments, the cell-killing whole culture or composition includes used cell culture medium, extracellular enzymes, and killed filamentous fungal cells. In some embodiments, methods known in the art can be used to permeate and / or lyse the microbial cells present in the cell-killing whole culture or composition.
[0322] The whole culture medium or cell composition described herein is typically a liquid, but may contain insoluble components, such as killed cells, cell debris, culture medium components, and / or one or more insoluble enzymes. In some embodiments, insoluble components may be removed to provide a clear liquid composition.
[0323] The whole-liquid formulations and cell compositions of the present invention can be produced by the methods described in WO 90 / 15861 or WO 2010 / 096673.
[0324] Composition
[0325] The present invention also relates to compositions comprising the protease of the present invention. Preferably, these compositions are enriched with such a protease. The term “enrichment” means that the protease activity of the composition has increased, for example, by an enrichment factor of at least 1.1, such as at least 1.2, at least 1.3, at least 1.4, at least 1.5, at least 2.0, at least 3.0, at least 4.0, at least 5.0, or at least 10.

[0336] Animal feed and animal feed additives
[0337] This invention also relates to animal feed compositions and animal feed additives. The animal feed compositions or diets have a relatively high protein content. Characteristics of poultry and pig diets are shown in columns 2-3 of Table B in WO 01 / 58275. Fish diets can be characterized as shown in column 4 of Table B. Furthermore, such fish diets typically have a crude fat content of 200-310 g / kg.
[0338] The animal feed composition according to the invention has a crude protein content of 50-800 g / kg, and further contains at least one or more proteases as described herein.
[0339] In addition, or alternatively (regarding the crude protein content mentioned above), the animal feed composition of the present invention has a metabolizable energy content of 10-30 MJ / kg; and / or a calcium content of 0.1-200 g / kg; and / or an available phosphorus content of 0.1-200 g / kg; and / or a methionine content of 0.1-100 g / kg; and / or a methionine plus cysteine content of 0.1-150 g / kg; and / or a lysine content of 0.5-50 g / kg.
[0340] In a specific embodiment, the contents of metabolizable energy, crude protein, calcium, phosphorus, methionine, methionine plus cysteine, and / or lysine fall within any one of WO 01 / 58275, Table B, ranges 2, 3, 4, or 5 (R.2-5).
[0341] Crude protein was calculated by multiplying nitrogen (N) by a factor of 6.25, i.e., crude protein (g / kg) = N (g / kg) x 6.25. Nitrogen content was determined by the Kjeldahl method (AOAC, 1984, Official Methods of Analysis, 14th edition, Association of Official Analytical Chemists, Washington, D.C.).
[0342] Metabolizable energy can be calculated from NRC publication *Nutrient Requirements in Swine*, Ninth Reprint 1988, National Research Council, Department of Agriculture, Animal Nutrition Society, Swine Nutrition Division. National Academy of Sciences Press, Washington, D.C., pp. 2–6, and the *European Table of Energy Values for Poultry Feed-stuffs*, Spelderholt Poultry Research and Extension Center, 7361DA Beckbergen, Netherlands, Grafisch bedrijf Ponsen & Looijen, Wageningen. ISBN 90-71463-12-5.
[0343] The dietary content of calcium, available phosphorus, and amino acids in a complete animal diet is calculated based on feed tables (such as Feed Table (Veevoedertabel) 1997, Chemical Composition Data (gegevens over chemische samenstelling), Digestibility and Nutritional Value of Feed (verteerbaarheid en voederwaarde van voedermiddelen), Central Veevoederbureau, Runderweg 6,8219pk Leylistard, ISBN 90-72839-13-7).
[0344] In a specific embodiment, the animal feed composition of the present invention comprises at least one plant protein as defined above.
[0345] The animal feed compositions of the present invention may also contain animal protein, such as meat and bone meal, feather meal, and / or fish meal, typically in an amount of 0-25%. The animal feed compositions of the present invention may also contain dried distillers grains with solubles, typically in an amount of 0-30%.
[0346] In a further specific embodiment, the animal feed composition of the present invention comprises 0-80% corn; and / or 0-80% sorghum; and / or 0-70% wheat; and / or 0-70% barley; and / or 0-30% oats; and / or 0-40% soybean meal; and / or 0-25% fish meal; and / or 0-25% meat and bone meal; and / or 0-20% whey.
[0347] The animal feed may include plant-based proteins. In specific embodiments, these plant-based proteins have a protein content of at least 10, 20, 30, 40, 50, 60, 70, 80, or 90% (w / w). The plant-based proteins may be derived from plant protein sources such as legumes and cereals, for example, materials derived from plants of the Fabaceae, Brassicaceae, Chenopodiaceae, and Poaceae families, such as soybean meal, lupin meal, rapeseed meal, and combinations thereof.
[0348] In one specific embodiment, the plant protein source is material from one or more plants of the Fabaceae family, such as soybean, lupin, pea, or bean. In another specific embodiment, the plant protein source is material from one or more plants of the Chenopodiaceae family, such as beet, sugar beet, spinach, or quinoa. Other examples of plant protein sources are rapeseed and cabbage. In another specific embodiment, soybean is a preferred plant protein source. Other examples of plant protein sources are cereals, such as barley, wheat, rye, oats, corn, rice, and sorghum.
[0349] Animal diets can be formulated, for example, into pastes (non-pelleted) or pellets. Typically, the milled feed is mixed and adequate amounts of essential vitamins and minerals are added according to the instructions for these types discussed. Enzymes are added in the form of solid or liquid enzyme formulations. For example, for pastes, solid or liquid enzyme formulations may be added before or during the ingredient mixing step. For pelleted feeds, the (solid or liquid) protease / enzyme preparation may also be added before or during the feed ingredient step. Typically, liquid protease / enzyme preparations include the protease of the present invention, optionally accompanied by a polyol (e.g., glycerol, ethylene glycol, or propylene glycol), and are added after the pelleting step, for example, by spraying the liquid formulation onto pellets. Enzymes can also be incorporated into feed additives or premixes.
[0350] Alternatively, proteases can be prepared by freezing a mixture of liquid enzyme solution and a leavening agent (e.g., ground soybean flour) and then freeze-drying the mixture.
[0351] In one embodiment, the composition includes one or more additional enzymes. In one embodiment, the composition includes one or more microorganisms. In one embodiment, the composition includes one or more vitamins. In one embodiment, the composition includes one or more minerals. In one embodiment, the composition includes one or more amino acids. In one embodiment, the composition includes one or more other feed ingredients.
[0352] In another embodiment, the composition comprises one or more polypeptides of the present invention, one or more formulation agents, and one or more additional enzymes. In one embodiment, the composition comprises one or more polypeptides of the present invention, one or more formulation agents, and one or more microorganisms. In one embodiment, the composition comprises one or more polypeptides of the present invention, one or more formulation agents, and one or more vitamins. In one embodiment, the composition comprises one or more polypeptides of the present invention and one or more minerals. In one embodiment, the composition comprises one or more polypeptides of the present invention, one or more formulation agents, and one or more amino acids. In one embodiment, the composition comprises one or more polypeptides of the present invention, one or more formulation agents, and one or more other feed ingredients.
[0353] In another embodiment, the composition comprises one or more polypeptides of the present invention, one or more formulation agents, and one or more components selected from the following list, which consists of: one or more additional enzymes; one or more microorganisms; one or more vitamins; one or more minerals; one or more amino acids; and one or more other feed ingredients.
[0354] The final protease concentration in the diet is in the range of 0.01-200 mg protease protein / kg diet, preferably between 0.5-100 mg / kg diet, more preferably 2-50 mg, and even more preferably 5-25 mg protease protein / kg animal diet.
[0355] Currently, it is considered to administer the protease at one or more of the following amounts (dosage ranges): 0.01-200; 0.01-100; 0.5-100; 1-50; 5-100; 5-50; 10-100; 0.05-50; 5-25; or 0.10-10 - all of these ranges are in mg (ppm) of protease protein per kg of feed.
[0356] To determine the number of mg of protease protein per kg of feed, the protease was purified from the feed composition, and the specific activity of the purified protease was determined using relevant tests (see Protease Activity). The protease activity of the feed composition was determined using the same tests, and the dosage, in mg of protease protein per kg of feed, was calculated based on these two determinations.
[0357] In one specific embodiment, the animal feed additive of the present invention is intended to be contained (or specified to be required to be contained) in animal diets or feeds at a level of 0.01% to 10.0%, more specifically 0.05% to 5.0% or 0.2% to 1.0% (% refers to g additive / 100g feed). Specifically, the same applies to premixes.
[0358] The same principle is used to determine the mg of protease protein in feed additives. Of course, if a sample of the protease used to prepare the feed additive or feed is available, the specific activity can be determined from that sample (without needing to purify the protease from the feed composition or additive).
[0359] Other enzymes
[0360] In another embodiment, the compositions described herein optionally include one or more enzymes. Enzymes can be classified based on the Enzyme Nomenclature manual from NC-IUBMB, 1992, and can also be found on the ENZYME website: http: / / www.expasy.ch / enzyme / . ENZYME is an information repository for enzyme nomenclature. It is primarily based on the recommendations of the International Union of Biochemistry and Molecular Biology Nomenclature Committee (IUB-MB), Academic Press, Inc., 1992, and describes each type of enzyme characterized, providing the enzyme with an EC (Enzyme Committee) number (Bairoch A. The ENZYME database, 2000, Nucleic Acids Res 28:304-305). The IUB-MB enzyme nomenclature is based on their substrate specificity and occasionally on their molecular mechanisms; this classification does not reflect the structural characteristics of these enzymes.

[0398] use
[0399] The present invention also relates to methods for using polypeptides or combinations thereof having protease activity (for example, for animal feed).
[0400] Uses in animal feed
[0401] The proteases of the present invention can also be used in animal feed. In one embodiment, the present invention provides a method for preparing an animal feed composition, the method comprising adding one or more proteases of the present invention to one or more animal feed ingredients.
[0402] According to WO 00 / 21381 and WO 04 / 026334, one or more proteases of the present invention can also be used in animal feed as feed-enhancing enzymes to improve feed digestibility and increase its utilization efficiency.
[0403] In another embodiment, the protease of the present invention can be used in animal feed or as a feed additive, wherein it can have a positive effect on the animal's digestive tract and thereby improve animal production performance, or improve animal health, such as reducing mortality, based on weight gain, feed conversion ratio (FCR), European Production Efficiency Factor (EPEF), European Production Effectiveness Factor (EFF). FCR is calculated as feed intake per animal relative to weight gain per animal.
[0404] In the application according to the invention, the protease can be fed to the animal before, after, or simultaneously with a diet. The latter is preferred.
[0405] In one specific embodiment, the form of the protease when added to or included in feed additives is explicitly defined. "Explicitly defined" means that the protease formulation is at least 50% pure, as determined by size exclusion chromatography (see Example 12 of WO 01 / 58275). In other specific embodiments, the protease formulation is at least 60%, 70%, 80%, 85%, 88%, 90%, 92%, 94%, or at least 95% pure, as determined by this method.
[0406] Specific protease formulations are advantageous. For example, it is easier to determine the correct dosage in feed for proteases that are substantially unaffected or uncontaminated by other proteases. The term "correct dosage" specifically refers to the goal of obtaining consistent and constant results, and the ability to optimize the dosage based on the desired effect.
[0407] However, for use in animal feed, proteases do not have to be pure; they can include other enzymes, in which case they can be called protease products.
[0408] This protease preparation can be (a) added directly to feed, or (b) it can be used in the production of one or more intermediate compositions, such as feed additives or premixes, which are subsequently added to feed (or used in the processing). Regardless of whether it is used according to (a) or (b) above, the purity mentioned above refers to the purity of the original protease preparation.
[0409] Specifically, protease preparations with the purity of the aforementioned order of magnitude can be obtained using recombinant production methods. However, when producing proteases using conventional fermentation methods, obtaining these protease preparations is not easy, and there are significant differences between batches.
[0410] These types of protease products can certainly be mixed with other enzymes.
[0411] The protein can be an animal protein, such as meat and bone meal, feather meal, and / or fish meal; or it can be a plant protein.
[0412] As used herein, the term plant-based protein refers to any compound, composition, formulation, or mixture comprising at least one protein derived from or derived from a plant, wherein said protein includes modified proteins or protein derivatives. In specific embodiments, the protein content of these plant-based proteins is at least 10%, 20%, 30%, 40%, 50%, or 60% (w / w).
[0413] Plant-based proteins can be derived from plant protein sources such as legumes and cereals, for example, materials derived from plants of the Fabaceae, Brassicaceae, Chenopodiaceae, and Poaceae families, such as soybean flour, lupin flour, and rapeseed flour.
[0414] In one specific embodiment, the plant-based protein source is material from one or more plants of the Fabaceae family (e.g., soybean, lupin, pea, or broad bean).
[0415] In another specific embodiment, the plant protein source is material derived from one or more plants of the Chenopodiaceae family, such as beets, sugar beets, spinach, or Quinoa.
[0416] Other examples of plant-based protein sources include rapeseed, sunflower seed, cottonseed, and cabbage.
[0417] Soybeans are a preferred source of plant-based protein.
[0418] Other examples of plant-based protein sources include cereals such as barley, wheat, rye, oats, corn, rice, black wheat, and sorghum.
[0419] In specific embodiments of the treatment process, the protease(s) discussed affect (or exert a hydrolytic or degrading effect on) these proteins, such as plant proteins or protein sources. To achieve this, the protein or protein source is generally suspended in a solvent, such as an aqueous solvent like water, and the pH and temperature values are adjusted with due attention to the characteristics of the enzyme(s) discussed. For example, treatment may be carried out at pH values that allow the actual protease activity to be at least 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, or at least 90%. Similarly, treatment may be carried out, for example, at temperatures that allow the actual protease activity to be at least 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, or at least 90%. The above activity percentages are relative to maximum activity. The enzymatic reaction is continued until the desired result is obtained, and the reaction can then be terminated by, for example, inactivating the enzyme through a heat treatment step, or the reaction may not be terminated.
[0420] In another specific embodiment of the processing procedure of the present invention, the action of the protease is maintained, which means that, for example, the protease is added to these proteins, but its hydrolytic effect is not activated until later when there is a need for it, once appropriate hydrolytic conditions are established, or once any enzyme inhibitor is inactivated, or whatever other way the action of the enzyme is delayed, its hydrolytic effect will be activated.
[0421] In one embodiment, the treatment is pre-treatment of animal feed or proteins used in animal feed, i.e., these proteins are hydrolyzed before ingestion.
[0422] The term "improving the nutritional value of animal feed" refers to enhancing the availability of nutrients in the feed. In this invention, improving nutritional value specifically refers to improving the availability of the protein portion of the feed, resulting in increased protein extraction, higher protein yield, and / or improved protein utilization. When the nutritional value of the feed increases, protein and / or amino acid digestibility increases, and the animal's growth rate and / or weight gain and / or feed conversion (i.e., feed intake relative to weight gain) can be improved.
[0423] Proteases can be added to feed in any form, such as when they are relatively pure proteases, or as a mixture with other components to be added to animal feed, i.e., in the form of animal feed additives, such as so-called animal feed premixes.
[0424] Preparation method
[0425] In one embodiment, the present invention also relates to a method for preparing animal feed or feed additives, the method comprising preparing an animal feed or feed additive comprising animal feed and a protease of the first aspect of the present invention.
[0426] In one embodiment, the present invention also relates to a method for preparing animal feed or feed additives, the method comprising preparing an animal feed or feed additive comprising animal feed and a protease of the second aspect of the present invention.
[0427] In one embodiment, the present invention also relates to a method for preparing animal feed or feed additives, the method comprising preparing an animal feed or feed additive comprising animal feed and a protease of the third aspect of the present invention.
[0428] In one embodiment, the present invention also relates to a method for preparing animal feed or feed additives, the method comprising preparing an animal feed or feed additive comprising animal feed and a protease of the fourth aspect of the present invention.
[0429] In one embodiment, the present invention also relates to a method for preparing animal feed or feed additives, the method comprising preparing animal feed or feed additives comprising animal feed and the protease of the fifth aspect of the present invention.
[0430] In one embodiment, the present invention also relates to a method for preparing animal feed or feed additives, the method comprising preparing an animal feed or feed additive comprising animal feed and a protease of the sixth aspect of the present invention.
[0431] Nucleic acid constructs, expression vectors, recombinant host cells, and methods for producing proteases
[0432] The present invention also relates to nucleic acid constructs, expression vectors and recombinant host cells comprising such polynucleotides encoding the protease of the present invention.
[0433] The present invention also relates to a method for producing a protease, comprising (a) culturing a recombinant host cell containing such a polynucleotide; and (b) recovering the protein.
[0434] The protein can be native or heterologous to the host cell. The term "protein" here does not refer to a specific length of encoded product and, therefore, encompasses peptides, oligopeptides, and proteins. The term "protein" also encompasses two or more polypeptides that combine to form the encoded product. These proteins also include hybrid polypeptides and fusion polypeptides.
[0435] Preferably, the protein is a protease. The gene can be obtained from any prokaryotic, eukaryotic, or other source.

The assay can be initiated by adding 100 μl of pNA substrate (50 mg, dissolved in 1.0 mL DMSO and further diluted 45-fold with 0.01% Triton X-100). Monitor OD. 405 The increase is used as a measure of protease activity.
[0527] 2) Protazyme AK assay:

[0535] Example 1: Expression of S1 protease 1 from *Hypericum* strain HTCC2649
[0536] Based on the publicly disclosed nucleotide sequence identified as SEQ ID NO:1, a codon-optimized synthetic gene with SEQ ID NO:3 was synthesized by GeneArt (GENEART AG BioPark, 11 Josef-Engert-Str., 93053, Regensburg, Germany). The synthetic gene was subcloned into a Bacillus expression vector using ClaI and MluI restriction enzyme sites, as described in WO 2012 / 025577. The S1 protease 1 was expressed using a Bacillus clausti secretion signal (with the following amino acid sequence: MKKPLGKIVASTALLISVAFSSSIASA, SEQ ID NO:6) instead of the native secretion signal. The expression plasmid was transformed into Bacillus subtilis. The expression cassette was integrated into the pectin lyase locus via homologous recombination. Transformants were selected on LB plates supplemented with 6 μg chloramphenicol per ml. A recombinant Bacillus subtilis clone containing the integrated expression construct was selected and designated as S1 protease 1 from *Haloxylon ammodendron* HTCC2649. It was cultured on a rotating shaker in 500 mL Erlenmeyer flasks with baffles, each containing 100 mL of yeast extract-based medium. The clone was cultured at 30°C for 3 days. The enzyme, containing the supernatant, was harvested and purified as described in Example 2.
[0537] Example 2: Purification of S1 protease 1 from *Haloxylon ammodendron* HTCC2649
[0538] The culture medium was centrifuged (20000x g, 20 min) and the supernatant was carefully decanted to separate it from the precipitate. The supernatant was filtered through a Nalgene 0.2 μm filter unit to remove any remaining Bacillus host cells. The 0.2 μm filtrate was transferred to a G25 dextran gel column (GE Healthcare) containing 10 mM MES / NaOH, 100 mM H3BO3, and 2 mM CaCl2 (pH 5.5). The enzyme transferred from the G25 dextran gel was applied to an SP-agarose gel FF column (GE Healthcare) equilibrated in 20 mM MES / NaOH (pH 5.5). After thoroughly washing the column with equilibration buffer, the protease was eluted using a linear gradient between the equilibration buffer and 20 mM MES / NaOH, 0.5 mM CaCl2, and 0.5 M NaCl (pH 5.5) for more than five column volumes. The main peak from an SP-agarose gel FF column (containing S1 protease 1 from Alternaria alternata) was merged, and solid ammonium sulfate was added to a final ammonium sulfate concentration of 1.6 M (NH4)2SO4. The ammonium sulfate-adjusted merged product was applied to a phenyl-agarose gel FF highly substituted column (from GE Healthcare), which was equilibrated in 10 mM MES / NaOH, 100 mM H3BO3, 2 mM CaCl2, and 1.6 M (NH4)2SO4 (pH 6.0). After thoroughly washing the column with equilibration buffer, the protease was eluted with a linear gradient of equilibration buffer and 10 mM MES / NaOH, 100 mM H3BO3, 10 mM MES, 2 mM CaCl2 (pH 6.0) + 25% 2-propanol for more than five column volumes. The main peak from a phenyl-agarose gel FF column (containing S1 protease 1 from *Hypericum fasciatus*) was merged and transferred to a G25 dextran gel column (GE Healthcare) in 20 mM CH3COOH / NaOH, 1 mM CaCl2 (pH 4.5). The enzyme transferred from the G25 dextran gel was then applied to an SP-agarose gel FF column (GE Healthcare) equilibrated in 20 mM MES / NaOH, 1 mM CaCl2 (pH 4.5). After thoroughly washing the column with equilibration buffer, the protease was eluted with a linear NaCl gradient (0-->0.5 M) in the same buffer for more than four column volumes. The protease activity from the column fraction was analyzed (measured using Protazyme AK at pH 7) and further analyzed by SDS-PAGE. Fractions showing only one band on a Coomassie-stained SDS-PAGE gel were merged, and the pH was adjusted to 5.8 with 3% NaOH. The condensate from the SP-agarose gel FF column was a purified formulation and used for further characterization.
[0539] Example 3: Characterization of S1 protease 1 (SEQ ID NO:5) from *Haloxylon ammodendron* HTCC2649
[0540] The Protazyme AK assay was used to obtain pH-activity and pH-stability profiles (residual activity after 2 hours at the indicated pH). For the pH-stability profile, the protease was diluted 8x in different assay buffers to achieve the pH values of those buffers and then incubated at 37°C for 2 hours. After incubation, the pH of the protease incubation was adjusted to the same pH as before the residual activity assay by dilution in a pH 8.0 assay buffer. The temperature-activity profile at pH 7.0 was obtained using the Protazyme AK assay.
[0541] The results are shown in Tables 2-4 below. Data for protease 10R (SEQ ID NO:8) are included in these tables. For Table 2, activity is relative to the optimal pH of the enzyme. For Table 3, activity is relative to the residual activity of the samples held under stable conditions (5°C, pH 8.0 or pH 9.0). For Table 4, activity is relative to the optimal temperature of the enzyme at pH 7.0 or pH 6.5. pH-activity and pH-stability profiles for protease 10R were obtained using the Suc-AAPF-pNA assay, and temperature-activity profiles were obtained using the Protazyme AK assay at pH 6.5.

[0556] The calculated molecular weight from this mature sequence is 20406.2 Da.
[0557] Example 4: Soybean-Corn Flour Activity Assay
[0558] The activity profile of the protease at pH 3–7 was obtained using soybean-corn flour as a substrate for endpoint determination.
[0559] Substrate: From the Danish Technological Institute, Gl. 1,6092 Stenderup obtains a mixture of soybean flour and corn flour at a ratio of 30:70. Commercial raw materials are milled ( 2mm sieve), mix for 10 minutes, then grind ( Mix for 10 minutes after passing through a 1mm sieve. Sieving analysis using a JEL 200 rotary sieve (J. Engelsmann AG, Ludwigshafen, Germany) showed that 1% of the particles were >500 micrometers and approximately 82% were <212 micrometers.
[0560] Assay buffer: Prepare five buffer solutions containing 100 mM succinic acid, 100 mM HEPES, 100 mM CHES, 100 mM CAPS, 12 mM CaCl2, 150 mM KCl, and 0.01% Triton X-100, and adjust the pH to one of the following values using HCl or NaOH: after mixing the soybean-corn flour substrate (1 g) with the assay buffer (10 mL), give a slurry with a final pH of one of the following: 3.0, 4.0, 5.0, 6.0, and 7.0.
[0561] Before adding the protease, mix the substrate slurry (2 mL) for 30 min and incubate at 40 °C (500 rpm) for 3 h. Dissolve the protease (200 mg enzyme protein / kg dry matter) in 100 μl of 100 mM sodium acetate buffer (9.565 g / L NaOAc, 1.75 g / L acetic acid, 5 mM CaCl2, 0.01% BSA, 0.01% Tween 20, pH 6.0) and add the protease. Centrifuge the sample (10 min, 4000 rpm, 0 °C) and analyze the collected supernatant using o-phthalaldehyde (OPA).
[0562] The results are shown in Table 5 and Figure 4 The proteolytic activity of S1 protease 1 from *Haloxylon ammodendron* HTCC2649 on soybean-corn flour increased with increasing pH from pH 3 to pH 7, and its activity was significantly higher than that of protease 10R across the entire pH range of 3–7, particularly in the pH range of 4–6. These data suggest that S1 protease 1 from *Haloxylon ammodendron* HTCC2649 has the potential to be more efficient in protein hydrolysis, for example in ruminants along with monogastric animals; for example in the crop of broilers with pH typically between 4 and 6, and in the stomach of pigs with pH varying from approximately 2 to 6 (depending on factors such as feed, gastric region, and time post-feeding).

[0564]
[0565] Example 5: Thermal stability
[0566] Desalt aliquots of the protease protein sample (purified as described in, for example, Examples 2, 9, or 11) or change the buffer to 20 mM sodium acetate, pH 4.0 using a pre-packed PD-10 column, or dialyze 2 x 500 ml of 20 mM sodium acetate, pH 4.0 at 4°C in a 2–3 h step, followed by an overnight step. Filter the sample 0.45 μm and dilute with buffer to approximately 2 A280 units. Use this dialysate as a reference in differential scanning calorimetry (DSC). Degas the samples using a vacuum aspirator and stir for approximately 10 minutes.
[0567] DSC scans were performed on a MicroCal VP-DSC at a constant scan rate of 1.5℃ / min from 20℃ to 90℃. Data processing was performed using MicroCal Origin software (version 4.10), and the denaturation temperature T was... d (also known as melting temperature T) m ) is defined as the temperature at the peak tip of the autocorrelation curve.
[0568] Example 6: Steam stability
[0569] The residual activity of the protease after steam treatment can be evaluated using the following assay.
[0570] In these experiments, modified settings were used so that the steam was supplied from a steam generator and introduced into the chamber. When the temperature reached approximately 93°C–94°C, the samples, placed on a plate, were inserted into the chamber via a drawer. After insertion, the temperature was reduced by 4°C. Incubation was performed for 30 seconds while maintaining a constant temperature of approximately 90°C. Afterward, the plate was quickly removed from the chamber, the samples were placed on ice for resuspending, and protease activity was assessed using assays such as Suc-AAPF-pNA or o-phthalaldehyde (OPA). Residual activity was calculated by comparing each enzyme sample with similar samples that had not undergone steam treatment.
[0571] Example 7: Granulation Stability Test
[0572] Enzyme granulation was performed as described in U.S. Patent No. 4,106,991, Example 1. The obtained particles were dried in a fluidized bed to a moisture content of less than 1% and sieved to obtain a product with particles ranging from 250 μm to 850 μm. Finally, the product was coated with palm oil and calcium carbonate as described in U.S. Patent No. 4,106,991, Example 22.
[0573] In a small horizontal mixer, approximately 50g of enzyme granules are premixed with 10kg of feed for 10 minutes. This premix is then mixed with 90kg of feed for 10 minutes in a large horizontal mixer. The feed is then transferred from the mixer to a regulator (a series mixer with steam injection) at a rate of approximately 300kg / hour. The regulator heats the feed to 95°C (measured at the exhaust port) by injecting steam. The residence time in the regulator is 30 seconds. The feed is then transferred from the regulator to a Simon Heesen press equipped with 3.0 x 35mm horizontal dies and compressed into pellets approximately 15mm in length. After compression, these pellets are placed in a cooler and cooled for 15 minutes.
[0574] The Suc-AAPF-pNA assay was used to measure protease activity before pelleting and after pelleting in the feed pellets. Pelletization stability was determined by comparing the protease activity in pelleted feed with that in non-pelleted feed.
[0575] Example 8: Expression of four variants of S1 protease 1 from the genus *Haloxylon ammodendron*
[0576] Four variants of S1 protease 1 from the genus *Haloxylon ammodendron* were prepared, each containing a single amino acid change. The amino acid changes were as follows: S68N, T71N, T87Q, and S90T (numbered based on SEQ ID NO:5). The four variants were constructed by incorporating the changes into the WT DNA sequence (SEQ ID NO:1) using PCR with the original construct DNA from Example 1 as a template and primers containing the DNA changes. Two DNA fragments were prepared for each construct, each fragment covering a portion of the gene and the upstream or downstream flanking region described in Example 1. The two fragments were fused together by SOE PCR to assemble the two fragments into a linear vector construct. Equal fractions of this SOE PCR product were transformed into *Bacillus subtilis*. Transformants were selected on LB plates supplemented with 6 μg chloramphenicol per ml. For each variant, a recombinant clone with a confirmed correct sequence containing a single amino acid change was selected for fermentation in liquid culture. The supernatant containing the enzyme was harvested and the four variant enzymes were purified as described in Example 9.
[0577] Example 9: Purification of S1 protease 1 from a variant of the genus *Haloxylon ammodendron*
[0578] Each variant was purified using the following procedure:
[0579] The culture medium was centrifuged (20000 x g, 20 min) and the supernatant was carefully decanted from the precipitate. The supernatant was filtered through a Nalgene 0.2 μm filter unit to remove any remaining Bacillus host cells. The filtrate was mixed 1:1 with 3.0 M (NH4)2SO4 to give a final ammonium sulfate concentration of 1.5 M (NH4)2SO4. The ammonium sulfate-adjusted filtrate was applied to a decyl-agarose column (from UpFront Chromatography) equilibrated in 5 mM MES / NaOH, 50 mM H3BO3, 1 mM CaCl2, and 1.5 M (NH4)2SO4 (pH 6.0). After thoroughly washing the column with equilibration buffer, the protease was gradually eluted with 10 mM MES / NaOH, 100 mM H3BO3, and 2 mM CaCl2 (pH 6.0) containing 30% 2-propanol. Elution peaks containing S1 protease 1 from variants of *Hypericum* were collected and transferred to a G25 dextran gel column (GE Healthcare) in 20 mM CH3COOH / NaOH, 1 mM CaCl2 (pH 4.5). The variant transferred from the G25 dextran gel was then applied to an SP-agarose gel FF column (GE Healthcare) equilibrated in 20 mM CH3COOH / NaOH, 1 mM CaCl2 (pH 4.5). After thorough washing of the column with equilibration buffer, the protease was eluted with a linear NaCl gradient (0-->0.5 M) in the same buffer for more than four column volumes. The protease activity of the fractions from the column was analyzed (measured using Protazyme AK at pH 7) and the major activity peak fraction was further analyzed by SDS-PAGE. Fractions showing only one band on Coomassie-stained SDS-PAGE gels were pooled as a purified formulation for further characterization.
[0580] Example 10: Expression of S1 protease 1 from *Terracoccus* sp.
[0581] Based on the nucleotide sequence identified as SEQ ID NO:10, a codon-optimized synthetic gene with SEQ ID NO:12 was synthesized by GeneArt (GENEART AG BioPark, 11 Josef-Engert-Str., 93053, Regensburg, Germany). The synthetic gene was subcloned into a Bacillus expression vector using ClaI and MluI restriction enzyme sites, as described in WO 2012 / 025577. The S1 protease 1 was expressed using a Bacillus clauri secretion signal (with the following amino acid sequence: MKKPLGKIVASTALLISVAFSSSIASA, SEQ ID NO:6) instead of the native secretion signal. The expression plasmid was transformed into Bacillus subtilis. The expression cassette was integrated into the pectin lyase locus via homologous recombination. Transformants were selected on LB plates supplemented with 6 μg chloramphenicol per ml. A recombinant Bacillus subtilis clone containing the integrated expression construct was selected and designated as S1 protease 1 from *Terracoccus* sp. It was cultured on a rotating shaker in 500 mL Erlenmeyer flasks with baffles, each containing 100 mL of yeast extract-based medium. The clone was cultured at 30°C for 3 days. The enzyme containing the supernatant was harvested and purified as described in Example 9.
[0582] Example 11: Purification of S1 protease 1 from *Terracoccus* sp.
[0583] The culture medium was centrifuged (20000x g, 20 min), and the supernatant was carefully decanted from the precipitate. The supernatant was filtered through a Nalgene 0.2 μm filter unit to remove any remaining Bacillus host cells. The pH of the 0.2 μm filtrate was adjusted to pH 8.0 with 3% NaOH, and this solution was applied to a MEP Hypercel column (from Pall Corporation) equilibrated in 20 mM Tris / HCl, 1 mM CaCl2 (pH 8.0). After thoroughly washing the column with equilibration buffer, the protease was eluted stepwise with 20 mM CH3COOH / NaOH, 1 mM CaCl2 (pH 4.5). The elution peak containing S1 protease 1 from *Terracoccus* sp. was collected and diluted 3x with demineralized water to reduce conductivity. The solution was pH adjusted to 4.5 and applied to a SOURCE 30S column (from GE Healthcare) equilibrated in 20 mM CH3COOH / NaOH, 1 mM CaCl2 (pH 4.5). After thoroughly washing the column with equilibration buffer, the protease was eluted with a linear gradient of equilibration buffer and 20 mM CH3COOH / NaOH, 1 mM CaCl2, 0.5 M NaCl (pH 4.5) for more than five column volumes. The protease activity of the fraction from the column was analyzed (using Suc-AAPF-pNA assay at pH 8), and the major activity peaks were pooled. Finally, the pH was adjusted to 5.0 with 3% NaOH. The pH-adjusted pooled product was a purified formulation used for further characterization.

For the pH-stability profile, the protease was diluted 8–10x in different assay buffers to achieve the desired pH and then incubated at 37°C for 2 hours. After incubation, the pH of the protease was adjusted to the same level as before the residual activity assay by dilution in a pH 8.0 assay buffer. Temperature-activity profiles at pH 7.0 were obtained using the Protazyme AK assay.

[0604] Example 13: Soybean-Corn Flour Activity Assay
[0605] The endpoint assay, as used in Example 4, with soybean-corn flour as the substrate, was used to obtain the activity profile of the protease at pH 3–7.
[0606] The results are shown in Table 9 and Figure 5 The proteolytic activity of S1 protease 1 from the *Haloxylon ammodendron* variant, together with that from *Terracoccus*, on soybean-corn flour increased with increasing pH from pH 3 to pH 7, and was significantly higher than that of protease 10R across the entire pH range of 3–7, particularly in the pH range of 4–6. These data suggest that S1 protease 1 from the *Haloxylon ammodendron* variant, together with that from *Terracoccus*, has the potential to be more efficient in protein hydrolysis, for example in ruminants and monogastric animals; such as in the crop of broilers typically at pH between 4 and 6, and in the stomach of pigs at pH varying from approximately 2 to 6 (depending on factors such as feed, gastric region, and time post-feeding).
[0607] Furthermore, S1 protease 1 from the variants S68N and T71N of Alternaria shares a very similar pH-activity profile with soybean-corn flour at 40°C with S1 protease 1 from the genus Terracoccus, and is significantly different from other proteases known in the art.

[0610] Example 14: Expression of S1 protease 1 from Norfolk's bacterium TL1
[0611] S1 protease 1 from *Nocturia flavum*, with the sequence SEQ ID NO:17 (SWISSPROT: A0A0A0JF07), was expressed as a codon-optimized synthetic gene (SEQ ID NO:18), in which the *Bacillus clausti* secretion signal replaced the native secretion signal as described in Example 10, giving the amino acid sequence SEQ ID NO:19. This gene was synthesized by GeneArt (GENEART AG BioPark, 11 Josef-Engert-Str., 93053, Regensburg, Germany). It was cloned and expressed as described in Example 10 for S1 protease 1 from *Terracoccus* sp.
[0612] Example 15: Purification of S1 protease 1 from Noorhizium anisopliae TL1
[0613] The culture medium was centrifuged (20000xg, 20 min), and the supernatant was carefully decanted from the precipitate. The supernatant was filtered through a Nalgene 0.2 μm filter unit to remove any remaining Bacillus host cells. The pH of the 0.2 μm filtrate was adjusted to pH 8.0 with 3M Tris base, and the pH-adjusted filtrate was applied to an MEP Hypercel column (Pall Corporation) equilibrated in 20 mM Tris / HCl and 1 mM CaCl2 (pH 8.0). After thoroughly washing the column with equilibration buffer, the protease was eluted stepwise with 20 mM CH3COOH / NaOH and 1 mM CaCl2 (pH 4.5). The elution peak containing S1 protease 1 from Noorhiza flavum TL1 was collected and diluted 3x with demineralized water to reduce conductivity. The solution was pH adjusted to 4.5 and applied to a SOURCE 30S column (from GE Healthcare) equilibrated in 20 mM CH3COOH / NaOH, 1 mM CaCl2 (pH 4.5). After thoroughly washing the column with equilibration buffer, the protease was eluted with a linear gradient of equilibration buffer and 20 mM CH3COOH / NaOH, 1 mM CaCl2, 0.5 M NaCl (pH 4.5) for more than five column volumes. The protease activity of the fraction from the column was analyzed (using Suc-AAPM-pNA assay at pH 8), and the major activity peaks were pooled. Finally, the pH was adjusted to 5.5 with 3% NaOH. The pH-adjusted pooled product was a purified formulation used for further characterization.
[0614] Example 16: Characterization of S1 protease 1 from Noorhizium anisopliae TL1 (SEQ ID NO:20)
[0615] pH-activity and pH-stability profiles of S1 protease 1 from *Nocturia flavum* TL1 were obtained using the Suc-AAPM-pNA assay. For the pH-stability profile, the protease was diluted 10x in different assay buffers to achieve the desired pH and then incubated at 37°C for 2 hours. After incubation, the pH of the protease was adjusted to the same level as before the residual activity assay by dilution in a pH 9.0 assay buffer. Temperature-activity profiles at pH 7.0 were obtained using the Protazyme AK assay.
[0616] The results are shown in Tables 10-12 below. Data for protease 10R are included in these tables. For Table 10, activity is relative to the enzyme's optimal pH. For Table 11, activity is relative to the residual activity of samples held at stable conditions (5°C, pH 9.0). For Table 12, activity is relative to the enzyme's optimal temperature at pH 7.0 or pH 6.5. pH-activity and pH-stability profiles for protease 10R were obtained using the Suc-AAPF-pNA assay, and temperature-activity profiles were obtained using the Protazyme AK assay at pH 6.5.
