Background Technology

[0005] Proteases (also known as prions) are enzymes that have the ability to break down other proteins. Proteases have the ability to initiate protein catabolism by hydrolyzing the peptide bonds that link amino acids together in the peptide or polypeptide chain that forms a protein. This activity of proteases as protein-digesting enzymes is called proteolytic activity. Many well-known procedures exist for measuring proteolytic activity (Kalisz, "Microbial Proteinases," in: Fiechter (edited)). Advances in Biochemical Engineering / Biotechnology [Advances in Biochemical Engineering / Biotechnology], (1988). For example, proteolytic activity can be determined by a comparative assay of the ability of various proteases to hydrolyze commercial substrates. Exemplary substrates that can be used to analyze protease or proteolytic activity include, but are not limited to, dimethyl casein (Sigma C-9801), bovine collagen (Sigma C-9879), bovine elastin (Sigma E-1625), and bovine keratin (ICN Biomedical 902111). Colorimetric assays using these substrates are well known in the art (see, for example, WO 99 / 34011 and U.S. Patent No. 6,376,450, both of which are incorporated herein by reference).

[0006] Serine proteases are enzymes containing serine residues as active sites to initiate the hydrolysis of protein peptide bonds (EC 3.4.21). Serine proteases comprise a wide variety of enzymes with broad specificity and biological functions, and based on their structure, they are further classified into chymotrypsin-like (trypsin-like) and subtilisin-like enzymes. The prototypical subtilisin (EC 3.4.21.62) was originally obtained from Bacillus subtilis. Subtilisin and its homologs are members of the S8 peptidase family according to the MEROPS classification scheme (Rawlings, ND et al. (2016) Twenty years of the MEROPS database of proteolytic enzymes, their substrates and inhibitors. Nucleic AcidsRes. 44, D343-D350). Members of the S8 family possess a catalytic triplet in their amino acid sequence of Asp, His, and Ser. Although many variant proteases have been developed for use in cleaning applications, there is still a need for improved protease variants. Summary of the Invention

[0010] manual

[0011] In one embodiment, this disclosure provides one or more Bacillus giganteus subtilisin protease variants comprising one or more amino acid substitutions as described in more detail below. In some embodiments, the variants provided herein exhibit one or more improved properties, such as improved cleaning performance, or improved stability, or both, when compared to subtilisin having the amino acid sequence of SEQ ID NO:2. The subtilisin protease variants provided herein can be used to prepare cleaning compositions (e.g., automatic dishwashing compositions). Furthermore, the subtilisin protease variants provided herein can also be used in cleaning methods (e.g., dishwashing methods) that use such variants or compositions comprising such subtilisin protease variants.

[0012] Unless otherwise indicated herein, one or more Substantiium subtilis protease variants described herein may be prepared and used by a variety of techniques used in molecular biology, microbiology, protein purification, protein engineering, protein and DNA sequencing, recombinant DNA fields, and industrial enzyme use and development. Undefined terms and abbreviations shall conform to their conventional meaning as used in the art. Unless otherwise defined herein, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. Any definitions provided herein shall be interpreted as a whole within the context of the specification. Unless the context clearly indicates otherwise, the singular “a / an” and “the” as used herein include the plural. Unless otherwise indicated, nucleic acid sequences are written from left to right in a 5' to 3' orientation; and amino acid sequences are written from left to right in an amino to carboxyl orientation. Each numerical range used herein includes each narrower numerical range falling within such a wider numerical range, as if all such narrower numerical ranges were explicitly stated herein.

[0013] As used herein in conjunction with numerical values, the term “about” refers to a range of + / - 0.5, unless the term is specifically defined otherwise in the context. For example, the phrase “pH of about 6” refers to a pH value of 5.5 to 6.5, unless the pH value is specifically defined otherwise.

[0014] The nomenclature for amino acid substitutions in one or more Substance protease variants described herein uses one or more of the following: position; position: one or more amino acid substitutions; or one or more starting amino acids: position: one or more amino acid substitutions. References to "position" (e.g., 5, 8, 17, 22, etc.) cover any starting amino acid that may be present at such position, and any substitution that may be present at such position. References to "position: one or more amino acid substitutions" (e.g., 1S / T / G, 3G, 17T, etc.) cover any starting amino acid that may be present at such position and one or more amino acids that may substitute for such starting amino acid. References to positions can be listed in several forms; for example, position 003 can also be referred to as position 03 or 3. References to starting or substituted amino acids can be further indicated as several starting or substituted amino acids separated by foreslashes (" / "). For example, D275S / K indicates that position 275 is replaced by serine (S) or lysine (K), and P / S197K indicates that the starting amino acid at position 197, proline (P) or serine (S), is replaced by lysine (K). References to X as a positional amino acid refer to any amino acid at the listed positions.

[0015] The positions of amino acid residues in a given amino acid sequence are numbered by corresponding to the amino acid sequence of SEQ ID NO:1. That is, the amino acid sequence of SEQ ID NO:1 is used as a reference sequence. For example, the amino acid sequences of one or more Bacillus subtilis protease variants described herein are aligned with the amino acid sequence of SEQ ID NO:1 using an alignment algorithm as described herein, and each amino acid residue in a given amino acid sequence aligned (preferably, best aligned) with the amino acid residues in SEQ ID NO:1 is conveniently numbered by referring to the numerical position of the corresponding amino acid residue. When compared with a query sequence (sometimes also called a “reference sequence”), a sequence alignment algorithm such as that described herein will identify one or more positions in the subject sequence where an insertion or deletion has occurred. Sequence alignment with other subtilisin proteases can be determined using amino acid alignment, for example, as shown in Figure 1 of PCT application No. PCT / US2018 / 062768, filed November 28, 2018, which claims priority to U.S. Provisional Application No. 62 / 591,976, filed November 29, 2017, entitled "Highly Stable Subtilisin Enzymes".

[0016] The terms “protease” and “proteinase” refer to enzymes that have the ability to break down proteins and peptides. Proteases have the ability to “proteolyze” proteins by hydrolyzing the peptide bonds that link amino acids together in the peptide or polypeptide chain that forms a protein. This activity of proteases as protein-digesting enzymes is called “proteolytic activity.” Many well-known procedures exist for measuring proteolytic activity. For example, proteolytic activity can be determined by a comparative assay analyzing the ability of each protease to hydrolyze a suitable substrate. Exemplary substrates that can be used to analyze protease or proteolytic activity include, but are not limited to, dimethylcasein (Sigma-Aldrich C-9801), bovine collagen (Sigma-Aldrich C-9879), bovine elastin (Sigma-Aldrich E-1625), and keratin (Keratin Azure) (Sigma-Aldrich K8500). Colorimetric assays using these substrates are well known in the art (see, for example, WO 99 / 34011 and US6,376,450). The pNA peptide assay (see, for example, Del Mar et al., Anal Biochem, 99:316-320, 1979) can also be used to determine the concentration of active enzymes. This assay measures the rate at which p-nitroaniline is released when the enzyme hydrolyzes a soluble synthetic substrate such as succinyl-alanine-alanine-proline-phenylalanine-p-nitroaniline (suc-AAPF-pNA). The rate of formation of the yellow color from the hydrolysis reaction is measured at 405 or 410 nm on a spectrophotometer, and this rate is proportional to the concentration of active enzyme. Additionally, absorbance measurements at 280 nm can be used to determine the total protein concentration in a purified protein sample. The activity of the substrate divided by the protein concentration gives the specific enzyme activity.

[0017] As used herein, “Bacillus” includes all species within the genus “Bacillus” as known to those skilled in the art, including but not limited to: Bacillus subtilis, Bacillus licheniformis, Bacillus lentus, Bacillus brevis, Bacillus stearothermophilus, Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus clausii, Bacillus halodurans, Bacillus megaterium, Bacillus coagulans, Bacillus circulans, Bacillus giganteus, and Bacillus thuringiensis. It should be recognized that the genus Bacillus is undergoing continuous taxonomic recombination. Therefore, the genus is intended to include species that have been reclassified, including but not limited to organisms such as *Geobacillus stearothermophilus* (now named *Geobacillus stearothermophilus*) or *B. polymyxa* (now named *Paenibacillus polymyxa*). The production of resistant endospores under stress conditions is considered a defining characteristic of the genus *Bacillus*, although this characteristic also applies to recently named genera such as *Alicyclobacillus*, *Amphibacillus*, *Aneurinibacillus*, *Anoxybacillus*, *Brevibacillus*, *Filobacillus*, *Gracilibacillus*, *Halobacillus*, *Paenibacillus*, *Salibacillus*, *Thermobacillus*, *Ureibacillus*, and *Virgibacillus*.

[0018] "Bacillus girdrensis subtilisin" includes any subtilisin derived from or derived from Bacillus girdrensis. In one embodiment, the Bacillus girdrensis subtilisin variants provided herein may be derived from Bacillus girdrensis clade subtilisin proteases (e.g., those described in WO 2015 / 089447 and WO2016 / 205755). Other Bacillus girdrensis subtilisin proteases include those described in U.S. Patent Application Publication No. 20090275493 and variants thereof, those described in International Patent Application Publication No. WO2016 / 087403 and variants thereof, and those described in U.S. Patent No. 7,449,187 and variants thereof. In other embodiments, Bacillus girdrensis subtilisin includes polypeptides having an amino acid sequence having at least 80% sequence identity with SEQ ID NO: 1 or 2.

[0019] The term "vector" refers to a nucleic acid construct used to introduce or transfer one or more nucleic acids into target cells or tissues. Typically, vectors are used to introduce exogenous DNA into cells or tissues. Vectors include plasmids, cloning vectors, bacteriophages, viruses (e.g., viral vectors), granules, expression vectors, shuttle vectors, etc. Typically, vectors include an origin of replication, a multiple cloning site, and a selectivity marker. Typically, the process of inserting a vector into a target cell is called transformation. In some embodiments, the present invention includes: a vector comprising a DNA sequence encoding a serine protease polypeptide (e.g., a precursor or mature serine protease polypeptide) that is efficiently linked to a suitable pre-sequence (e.g., a secretory, signal peptide sequence, etc.), said vector being capable of expressing the DNA sequence in a suitable host, as well as folding and translocation of the recombinant polypeptide chain.

[0020] As used herein, in the context of introducing nucleic acid sequences into cells, the term "introduction" refers to any method suitable for transferring nucleic acid sequences into cells. Such introduction methods include, but are not limited to, protoplast fusion, transfection, transformation, electroporation, conjugation, and transduction. Transformation refers to genetic changes in cells caused by uptake, optional genome incorporation, and expression of genetic material (e.g., DNA).

[0021] The term "expression" refers to the transcription and stable accumulation of sense (mRNA) or antisense RNA derived from the nucleic acid molecules of this disclosure. Expression can also refer to the translation of mRNA into a polypeptide. Therefore, the term "expression" includes any step involved in "polypeptide production," including but not limited to transcription, post-transcriptional modification, translation, post-translational modification, secretion, etc.

[0022] The phrase "expression cassette" or "expression vector" refers to a nucleic acid construct or vector, recombinantly or synthetically produced, for expressing a target nucleic acid (e.g., a foreign nucleic acid or a transgene) in target cells. Typically, the target nucleic acid expresses a target protein. Typically, an expression vector or expression cassette contains a promoter nucleotide sequence that drives or promotes the expression of a foreign nucleic acid. Typically, an expression vector or expression cassette also includes other specified nucleic acid elements that allow the transcription of a specific nucleic acid in the target cell. Recombinant expression cassettes can be incorporated into plasmids, chromosomes, mitochondrial DNA, plastid DNA, viruses, or nucleic acid fragments. Some expression vectors have the ability to incorporate and express heterologous DNA fragments into host cells or the host cell genome. Many prokaryotic and eukaryotic expression vectors are commercially available. Selecting a suitable expression vector for protein expression from the nucleic acid sequence incorporated into the expression vector is within the knowledge of those skilled in the art.

[0023] As used herein, when a nucleic acid is placed in a functional relationship with another nucleic acid sequence, that nucleic acid is “effectively linked” to the other nucleic acid sequence. For example, if a promoter influences the transcription of a coding sequence, then the promoter or enhancer is effectively linked to the nucleotide coding sequence. If a ribosome binding site is located to facilitate the translation of a coding sequence, then that ribosome binding site can be effectively linked to the coding sequence. Typically, “effectively linked” DNA sequences are contiguous. However, enhancers do not have to be contiguous. Linkage is achieved by joining at a convenient restriction site. If such a site is not present, synthetic oligonucleotide adaptors or linkers can be used according to standard practice.

[0024] The term "gene" refers to a polynucleotide (e.g., a segment of DNA) that encodes a polypeptide and includes regions before and after the coding region. In some cases, a gene includes spacer sequences (introns) between individual coding regions (exons).

[0025] When used in relation to cells, the term "recombinant" typically indicates that the cell has been modified by introducing a foreign nucleic acid sequence, or that the cell is derived from a cell that has been so modified. For example, a recombinant cell may contain genes that are not present in the same form in the natural (non-recombinant) form of the cell, or a recombinant cell may contain natural genes (found in the natural form of the cell) that have been modified and reintroduced into the cell. Recombinant cells may contain nucleic acids that are endogenous to cells that have been modified but have not had the nucleic acids removed from the cells; such modifications include those obtained through gene substitution, site-specific mutations, and related techniques known to those skilled in the art. Recombinant DNA technology includes techniques for producing recombinant DNA in vitro and transferring said recombinant DNA into cells in which it can be expressed or propagated to produce recombinant polypeptides. "Recombination" of polynucleotides or nucleic acids generally refers to the assembly or combination of two or more nucleic acid or polynucleotide chains or fragments to produce new polynucleotides or nucleic acids.

[0026] If a nucleic acid or polynucleotide can be transcribed and / or translated to produce a polypeptide or fragment thereof in its natural state or when manipulated by methods known to those skilled in the art, then the nucleic acid or polynucleotide may be said to "encode" the polypeptide. The antisense strand of such a nucleic acid may also be referred to as encoding a sequence.

[0027] The terms “host strain” and “host cell” refer to the appropriate host for an expression vector containing the target DNA sequence.

[0028] A "protein" or "peptide" is a polymeric sequence of amino acid residues. The terms "protein" and "peptide" are used interchangeably herein. Throughout this disclosure, single-letter and three-letter codes for amino acids are used in accordance with the definitions provided by the Joint Commission on Biochemical Nomenclature (JCBN) of IUPAC-IUB. The single-letter X refers to any one of the twenty amino acids. It should also be understood that, due to the degeneracy of the genetic code, a polypeptide can be encoded by more than one nucleotide sequence.

[0029] The terms "presequence" or "prepeptide sequence" refer to the amino acid sequence between the signal peptide sequence and the mature protease sequence, essential for the proper folding and secretion of the protease; they are sometimes referred to as intramolecular chaperones. Cleavage of the presequence or prepeptide sequence yields the mature, active protease. Bacterial serine proteases are often represented as preenzymes. For example, examples of modified prepeptides are provided in WO 2016 / 205710.

[0030] The terms "signal sequence" and "signal peptide" refer to amino acid residue sequences that can participate in the secretion or directed transport of proteins in their mature or precursor forms. Typically, the signal sequence is located at the N-terminus of the precursor or mature protein sequence. The signal sequence can be endogenous or exogenous. Signal sequences are generally absent in mature proteins. Typically, after protein transport, the signal sequence is cleaved from the protein by a signal peptidase.

[0031] The term "mature" form of a protein, polypeptide, or peptide refers to a functional form of a protein, polypeptide, or peptide that lacks a signal peptide sequence and a propeptide sequence.

[0032] The term "precursor" refers to a protein or peptide in its mature form that has a pre-sequence effectively linked to the amino or carboxyl terminus of the protein. A precursor may also have a "signal" sequence effectively linked to the amino terminus of the pre-sequence. A precursor may also have additional polypeptides involved in post-translational activity (e.g., polypeptides cleaved from which the mature protein or peptide is left).

[0033] Regarding polypeptides, the term "wild-type" refers to a naturally occurring polypeptide that does not contain artificial substitutions, insertions, or deletions at one or more amino acid positions. Similarly, regarding polynucleotides, the term "wild-type" refers to a naturally occurring polynucleotide that does not contain artificial substitutions, insertions, or deletions at one or more nucleotide positions. However, polynucleotides encoding wild-type polypeptides are not limited to naturally occurring polynucleotides and encompass any polynucleotide encoding either wild-type or parental polypeptides.

[0034] Regarding polypeptides, the term "parent" includes reference to naturally occurring or wild-type polypeptides, or naturally occurring polypeptides in which one or more amino acid positions have been artificially substituted, inserted, or deleted. Regarding polypeptides, the term "parent" also includes any polypeptide with protease activity that acts as a starting polypeptide for modification (such as substitution, addition, and / or deletion) to produce a variant with one or more modifications compared to the starting polypeptide. That is, parent or reference polypeptides are not limited to naturally occurring wild-type polypeptides and encompass any wild-type, parent, or reference polypeptide. Similarly, regarding polynucleotides, the term "parent" can refer to naturally occurring polynucleotides or polynucleotides that do indeed include artificially substituted, inserted, or deleted polynucleotides at one or more nucleotide positions. Regarding polynucleotides, the term "parent" also includes any polynucleotide encoding a polypeptide with protease activity that acts as a starting polynucleotide for modification to produce a variant protease with modifications such as substitution, addition, and / or deletion compared to the starting polynucleotide. That is, polynucleotides encoding wild-type, parent, or reference polypeptides are not limited to naturally occurring polynucleotides and encompass any polynucleotide encoding wild-type, parent, or reference polypeptides. In some embodiments, the parental polypeptide comprises Bacillus subtilis protease. In some embodiments, the parental polypeptide herein comprises a polypeptide having the amino acid sequence shown in SEQ ID NO:1.

[0035] The term "naturally occurring" refers, for example, sequences and residues found in nature (e.g., polypeptide sequences and amino acid sequences or nucleotide sequences and nucleotide sequences). Conversely, the term "non-naturally occurring" refers, for example, sequences and residues not found in nature (e.g., polypeptide sequences and amino acid sequences or nucleotide sequences and nucleic acid sequences).

[0036] As used herein, "corresponding to" or "corresponds to" refers to an amino acid residue at the listed position in a protein or peptide, or an amino acid residue that is similar to, homologous to, or equivalent to the listed residue in a protein or peptide. As used herein, "corresponding region" generally refers to a similar position in a related or reference protein.

[0037] The terms "derived from" and "obtained from" refer not only to proteins produced or potentially produced by strains of the organism in question, but also to proteins encoded by DNA sequences isolated from such strains and produced in host organisms containing such DNA sequences. Additionally, the terms refer to proteins encoded by DNA sequences derived from synthetic and / or cDNA and possessing the identifying characteristics of the protein in question. For example, "proteases derived from the genus Bacillus" refers to those enzymes with proteolytic activity naturally produced by the genus Bacillus, as well as serine proteases, such as those produced from Bacillus but produced by other host cells transformed with nucleic acids encoding serine proteases using genetic engineering techniques.

[0038] In the context of two polynucleotide or polypeptide sequences, the term “identity” refers to the fact that the nucleotides or amino acids in the two sequences are identical when compared to the maximum correspondence, as measured using sequence comparison or analysis algorithms described below and known in the art.

[0039] The phrase “% identity” or “percentage identity” or “PID” refers to protein sequence identity. Percentage identity can be determined using standard techniques known in the art. The percentage of amino acid identity shared by a target sequence can be determined by aligning sequences to directly compare sequence information (e.g., using programs such as BLAST, MUSCLE, or CLUSTAL). The BLAST algorithm is described, for example, in Altschul et al., J Mol Biol [Journal of Molecular Biology], 215:403-410 (1990) and Karlin et al., Proc Natl Acad Sci USA [Proceedings of the National Academy of Sciences of the United States of America], 90:5873-5787 (1993). The percentage (%) amino acid sequence identity value is determined by dividing the number of matching identical residues by the total number of residues in the “reference” sequence (including any gaps created by the program for best / maximum alignment). The BLAST algorithm refers to the “reference” sequence as the “query” sequence.

[0040] As used herein, “homological protein” or “homological protease” refers to proteins that have different similarities in primary, secondary, and / or tertiary structures. When comparing proteins, protein homology can refer to the similarity of linear amino acid sequences. Homology can be determined by amino acid sequence alignment, for example, using programs such as BLAST, MUSCLE, or CLUSTAL. Homology searches of protein sequences can be performed using BLASTP and PSI-BLAST from NCBI BLAST with a threshold (E-value cutoff) of 0.001. (Altschul et al., “Gapped BLAST and PSI BLAST: a new generation of protein database search programs”, Nucleic Acids Res, Group 1; 25(17):3389-402(1997)). The BLAST program uses several search parameters, most of which are set to default values. The NCBI BLAST algorithm finds the most relevant sequences based on biological similarity, but it is not recommended for query sequences with fewer than 20 residues (Altschul et al., Nucleic Acids Res, 25:3389-3402, 1997 and Schaffer et al., Nucleic Acids Res, 29:2994-3005, 2001). Exemplary default BLAST parameters for nucleic acid sequence searching include: adjacent word length threshold = 11; E-value cutoff = 10; scoring matrix = NUC.3.1 (match = 1, mismatch = -3); gap open = 5; and gap extension = 2. Exemplary default BLAST parameters for amino acid sequence searching include: word length = 3; E-value cutoff = 10; scoring matrix = BLOSUM62; gap open = 11; and gap extension = 1. Using this information, protein sequences can be grouped and / or phylogenetic trees can be constructed from them. Amino acid sequences can be input into programs such as the Vector NTI Advance suite, and guide trees can be created using the Neighbor Joining (NJ) method (Saitou and Nei, Mol Biol Evol [Molecular Biology and Evolution], 4:406-425, 1987). The tree structure can be calculated using Kimura correction for sequence distances and ignoring positions with vacancies. Programs such as AlignX can display the calculated distance values ​​in parentheses after the molecule name displayed on the phylogenetic tree.

[0041] Understanding homology between molecules can reveal their evolutionary history and functional information; if a newly sequenced protein is homologous to a previously characterized protein, there is a strong indication of the new protein's biochemical function. Two molecules are said to be homologous if they derive from a common ancestor. Homologous molecules or homologs can be divided into two categories: paralogs and orthologs. Paralogs are homologs that exist within a single species. Paralogs often differ in their detailed biochemical functions. Orthologs are homologs that exist in different species and have very similar or identical functions. A protein superfamily is the largest group (clade) of proteins whose common ancestor can be inferred. This common ancestor is usually based on sequence alignment and mechanical similarity. Typically, a superfamily contains several protein families that show sequence similarity within the family. Based on the MEROPS protease classification system, the term "protein family" is often used for protease superfamilies. As used herein, the term “subtilisin” includes any member of the S8 serine protease family as described in the MEROPS-peptidase database (Rawlings, ND et al. (2016) Twenty years of the MEROPS database of proteolytic enzymes, their substrates and inhibitors [Nucleic Acids Res] 44, D343-D350).

[0042] The CLUSTAL W algorithm is another example of a sequence alignment algorithm (see Thompson et al., Nucleic Acids Res [Nucleic Acids Research] 22:4673-4680, 1994). The default parameters for the CLUSTAL W algorithm include: Vacancy open penalty = 10.0; Vacancy extension penalty = 0.05; Protein weight matrix = BLOSUM series; DNA weight matrix = IUB; Delayed divergence sequence % = 40; Vacancy separation distance = 8; DNA conversion weight = 0.50; List hydrophilic residues = GPSNDQEKR; Use negative matrix = off; Switch special residue penalty = on; Switch hydrophilic penalty = on; and Switch end vacancy separation penalty = off. In the CLUSTAL algorithm, deletions occurring at any end are included. For example, a variant with a five-amino acid deletion at any end (or within) of a 500-amino acid polypeptide will have 99% (495 / 500 identical residues × 100) percentage sequence identity relative to the "reference" polypeptide. Such variants will be covered by variants that have “at least 99% sequence identity” with the polypeptide.

[0043] A nucleic acid or polynucleotide is "separated" when it is at least partially or completely separated from other components, including but not limited to other proteins, nucleic acids, cells, etc. Similarly, a polypeptide, protein, or peptide is "separated" when it is at least partially or completely separated from other components, including but not limited to other proteins, nucleic acids, cells, etc. The separated species is more abundant than other species in the composition, in molar terms. For example, the separated species may constitute at least about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or about 100% (in molar terms) of all present macromolecular species. Preferably, the target species is purified to substantially homogeneity (i.e., contaminant species are not detectable in the composition by conventional detection methods). Purity and homogeneity can be determined using many techniques well-known in the art, such as agarose or polyacrylamide gel electrophoresis of nucleic acid or protein samples, followed by visualization after staining. If necessary, high-resolution techniques such as high-performance liquid chromatography (HPLC) or similar methods can be used to purify the substances.

[0044] The term "purified," when applied to nucleic acids or peptides, generally means nucleic acids or peptides that are substantially free of other components, as determined by analytical techniques well known in the art (e.g., purified peptides or polynucleotides form discrete bands in electrophoresis gels, chromatographic eluates, and / or media subjected to density gradient centrifugation). For example, a nucleic acid or peptide that produces substantially one band in an electrophoresis gel is "purified." Purified nucleic acids or peptides are at least about 50% pure, and typically at least about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, about 99.5%, about 99.6%, about 99.7%, about 99.8%, or more pure (e.g., percentage by weight on a molar basis). In a relevant sense, a composition is enriched for the molecules when there is a significant increase in the concentration of the molecules after the application of purification or enrichment techniques. The term "enrichment" refers to the presence of a compound, polypeptide, cell, nucleic acid, amino acid, or other specific substance or component in the composition at a relative or absolute concentration higher than that in the starting composition.

[0045] The term "tableware" refers to all forms of tableware, including all forms of tableware (such as plates, cups, glasses, and bowls); all forms of cutlery (such as spoons, knives, forks, and serving utensils); all forms of ceramics; all forms of plastics (such as melamine); and all metal, porcelain, glass, and acrylic products.

[0046] The term "cleaning activity" refers to the cleaning performance achieved by a serine protease polypeptide, variant, or reference subtilisin under the primary conditions during the proteolysis, hydrolysis, cleaning, or other processes disclosed herein. In some embodiments, the cleaning performance of the serine protease or reference subtilisin can be determined by various assays for cleaning one or more enzyme-sensitive stains (e.g., stains caused by food, grass, blood, ink, milk, oil, and / or egg protein) on an article or surface. The cleaning performance of one or more subtilisin variants or reference subtilisins described herein can be determined by subjecting stains on an article or surface to one or more standard washing conditions and assessing the extent of stain removal using various chromatographic, spectrophotometric, or other quantitative methods. Exemplary cleaning assays and methods are known in the art and include, but are not limited to, those described in WO 99 / 34011 and US 6,605,458, as well as those included in the examples provided below.

[0047] The term "effective amount" used in the description of one or more subtilisin variants or reference subtilisin proteases herein refers to the amount of protease that achieves the desired level of enzymatic activity in a specific cleaning composition. Such effective amounts can be readily determined by those skilled in the art and are based on many factors, such as the specific protease used, the cleaning application, the specific composition of the cleaning composition, and whether a liquid or dry (e.g., granular, tablet, or stick) composition is required.

[0048] The term "auxiliary material" refers to any liquid, solid, or gaseous substance, or recombinant polypeptide or its active fragment, contained in a cleaning composition other than one or more Bacillus subtilis protease variants described herein. In some embodiments, the cleaning compositions of this disclosure include one or more cleaning auxiliary materials. Typically, each cleaning auxiliary material is selected depending on the specific type and form of the cleaning composition (e.g., liquid, granules, powder, stick, paste, spray, tablet, gel, foam, or other composition). Preferably, each cleaning auxiliary material is compatible with the protease used in the composition.

[0049] Cleaning compositions and cleaning formulations include any composition suitable for cleaning, bleaching, disinfecting, and / or sterilizing any object, article, and / or surface.

The invention may also use single-dose unit forms, including but not limited to pills, tablets, gelcaps, or other single-dose units such as pre-measured powders or liquids.

[0050] Unless otherwise indicated, cleaning compositions or cleaning formulations as used herein include general-purpose or heavy-duty detergents in granular or powder form, particularly cleaning detergents; general-purpose detergents in liquid, granular, gel, solid, tablet, paste, or unit dosage forms, particularly so-called heavy-duty liquid (HDL) detergents or heavy-duty dry cleaning (HDD) detergent types; liquid fine fabric detergents; hand or manual dishwashing detergents, including those of high-foaming types; hand or manual dishwashing detergents, automatic dishwashing detergents, or dish or tableware detergents, including various tablet, powder, solid, granular, liquid, gel, and rinsing aid types for household and institutional use; liquid cleaning and disinfecting agents, including antibacterial handwashing types, cleaning sticks, mouthwash, denture cleaners, car wash shampoos, carpet shampoos, and bathroom cleaners; hair shampoos and / or hair rinsing agents for human and other animal use; shower gels and foam baths and metal cleaners; and cleaning aids such as bleach additives and “stain remover sticks” or pretreatment types. In some embodiments, the particulate composition is in a “compact” form; in some embodiments, the liquid composition is in a “concentrated” form.

[0051] Regarding compositions used in washing media intended for cleaning soiled or dirty objects, including certain fabric and / or non-fabric objects or articles, the terms "detergent composition" or "detergent formulation" are used. In some embodiments, the detergents disclosed herein comprise one or more variants of Bacillus subtilis protease described herein, and additionally comprise one or more surfactants, one or more transferases, hydrolases, oxidoreductases, builders (e.g., builder salts), bleach, bleach activators, bluing agents, fluorescent dyes, caking inhibitors, masking agents, enzyme stabilizers, calcium, enzyme activators, antioxidants, and / or solubilizers. In some cases, the builder salt is a mixture of silicates and phosphates, preferably having more silicates (e.g., sodium metasilicate) than phosphates (e.g., sodium tripolyphosphate). Some embodiments relate to cleaning compositions or detergent compositions that do not contain any phosphates (e.g., phosphates or phosphate builders).

[0052] The phrases “one or more compositions that are substantially free of boron” or “one or more detergents that are substantially free of boron” refer to one or more compositions or detergents containing trace amounts of boron (e.g., less than about 1000 ppm (1 mg / kg or 1 mg / L equals 1 ppm), less than about 100 ppm, less than about 50 ppm, less than about 10 ppm, or less than about 5 ppm, or less than about 1 ppm), the boron of which may be derived from other compositions or detergent ingredients.

[0053] The term "bleaching" refers to treating a material (e.g., fabrics, clothing, pulp, etc.) or surface for a sufficiently long time and / or under suitable pH and / or temperature conditions to achieve whitening (i.e., brightening) and / or cleaning of said material. Examples of chemicals suitable for bleaching include, but are not limited to, ClO2, H2O2, peracids, NO2, etc. Bleaching agents also include enzymatic bleaching agents, such as perhydrolases and aryl esterases. Another embodiment relates to compositions comprising one or more Bacillus subtilis protease variants described herein and one or more perhydrolases, such as the perhydrolases described in WO 2005 / 056782, WO 2007 / 106293, WO 2008 / 063400, WO 2008 / 106214, and WO 2008 / 106215.

[0054] The term "washing performance" for a protease (e.g., one or more variants of the Bacillus subtilis protease described herein, or their recombinant polypeptides or active fragments) refers to the additional cleaning contribution of the one or more Bacillus subtilis protease variants described herein to the washing performance compared to a detergent without the addition of the one or more Bacillus subtilis protease variants described herein to the composition. Washing performance is compared under relevant washing conditions. In some testing systems, other relevant factors, such as detergent composition, sud concentration, water hardness, washing mechanics, time, pH, and / or temperature, can be controlled in a manner that mimics one or more conditions typical for household applications in certain market segments (e.g., hand washing or manual dishwashing, automatic dishwashing, tableware cleaning, countertop cleaning, fabric cleaning, etc.).

[0055] This article uses the phrase "relevant washing conditions" to indicate the conditions actually used in the home in the hand-washing, automatic dishwashing, or laundry detergent segments, specifically washing temperature, time, washing mechanics, foam concentration, detergent type, and water hardness.

[0056] The term "dishwashing" refers to both household and industrial dishwashing, and encompasses both automated dishwashing (e.g., washing with a dishwashing machine) and manual dishwashing (e.g., washing by hand).

[0057] The term "disinfection" refers to the removal of contaminants from surfaces, as well as the inhibition or killing of microorganisms on the surface of objects.

In conventional detergent compositions, filler salt is present in a basic amount, typically from about 17% to about 35% by weight of the total composition. In contrast, in compact compositions, filler salt is present in an amount not exceeding about 15% of the total composition. In some embodiments, filler salt is present in an amount not exceeding about 10%, or more preferably about 5%, by weight of the composition. In some embodiments, the inorganic filler salt is selected from alkali salts and alkaline earth metal salts of sulfates and chlorides. In some embodiments, the filler salt is sodium sulfate.

[0072] This disclosure includes variants of the subtilisin protease having one or more modifications on surface-exposed amino acids. The surface modifications of the enzyme variant can be used in detergent compositions by having a minimum performance index for detergent performance, enzyme stability in detergent compositions, and enzyme thermal stability, while simultaneously having at least one of these characteristics that are improved relative to the parental subtilisin protease. In some embodiments, the surface modification alters the hydrophobicity and / or charge of the amino acid at that location. Hydrophobicity can be determined using techniques known in the art, such as those described by White and Wimley (White, SH and Wimley, WC, (1999) Annu. Rev. Biophys. Biomol. Struct [Annual Review of Biophysics and Biomolecular Structure] 28:319-65). As used herein, “surface property” can refer to electrostatic charge and properties exhibited by the protein surface, such as hydrophobicity and hydrophilicity. In even further embodiments, one or more subtilisin protease variants described herein have one or more improved properties when compared to a reference subtilisin protease or parental subtilisin protease; wherein said improved property is selected from improved detergent cleaning performance, improved stability, and combinations thereof. In another embodiment, the parental subtilisin protease comprises the amino acid sequence of SEQ ID NO:1. In another embodiment, the parental subtilisin protease is a polypeptide having the amino acid sequence of SEQ ID NO:1. In yet another embodiment, the improved property is (i) improved detergent cleaning performance, wherein said variant has a cleaning PI of ≥1.1 for crème brûlée and / or egg stains; and / or (ii) improved stability, wherein said variant has a stability PI of ≥1.1. In yet another embodiment, the detergent cleaning performance is measured according to the cleaning performance in the ADW detergent assay of Example 2; and / or the stability is measured according to the stability assay of Example 2.

[0073] In the context of oxidation, chelating agents, denaturing agents, surfactants, and heat- and / or pH-stabilized proteases, the term "enhanced stability" or "improved stability" refers to a higher retention of proteolytic activity over time compared to a reference protease (e.g., wild-type or parental protease). Autolysis has been identified as a mode of loss of activity of Bacillus subtilis protease in liquid detergents. (Stoner et al., 2004, Protease autolysis in heavy-duty liquid detergent formulations: effects of thermodynamic stabilizers and protease inhibitors, Enzyme and Microbial Technology 34:114-125).

[0074] The terms "thermally stable," "thermostable," and "thermostability" for protease variants refer to the retention of a specified amount of enzymatic activity by the protease after exposure to altered temperatures for a given period of time under primary conditions (or "stress conditions") during proteolysis, hydrolysis, cleaning, or other processes. "Alternated temperature" encompasses both increases and decreases in temperature.

[0075] In some embodiments, the variant protease provided herein is available at a given time interval (e.g., at least about 5 minutes, at least about 20 minutes, at least about 60 minutes, about 90 minutes, about 120 minutes, about 180 minutes, about 240 minutes, about 300 minutes, about 360 minutes, about 420 minutes, about 480 minutes, about 540 minutes, about 600 minutes, about 660 minutes, about 720 minutes, about 780 minutes, about 840 minutes, about 900 minutes, about 960 minutes, about 1020 minutes, about 1080 minutes).

In some embodiments, the plasmid is subsequently isolated from E. coli cells and transformed into Bacillus cells. However, the use of an intervening microorganism such as E. coli is not necessary, and in some embodiments, the DNA construct or vector is introduced directly into the Bacillus host.

[0107] Exemplary methods for introducing one or more nucleic acid sequences described herein into Bacillus cells are described in, for example, Ferrari et al., “Genetics”, in Hardwood et al. (ed.), Bacillus, Plenum Publishing Corp. (1989), pp. 57–72; Saunders et al., J. Bacteriol., 157:718–726 (1984); Hoch et al., J. Bacteriol., 93:1925–1937 (1967); Mann et al., Current Microbiol., 13:131–135 (1986); Holubova, Folia Microbiol. [Fria Microbiology], 30:97 (1985); Chang et al., Mol. Gen. Genet. [Molecular and General Genetics] 168:11-115 (1979); Vorobjeva et al., FEMS Microbiol. Lett. [FEMS Microbiology Letters] 7:261-263 (1980); Smith et al., Appl. Env. Microbiol [Applied and Environmental Microbiology] 51:634 (1986); Fisher et al., Arch. Microbiol. [Archives of Microbiology], 139:213-217 (1981); and McDonald, J. Gen. Microbiol [Journal of Genetic Microbiology] 130:203 (1984). In fact, methods such as transformation (including protoplast transformation and transfection, transduction and protoplast fusion) are well known and suitable for use in this paper. Methods known in the art for transforming Bacillus cells include, for example, plasmid-labeled rescue transformation, which involves the uptake of a donor plasmid by competent cells carrying a partially homologous resident plasmid (see, Contente et al., Plasmid 2:555-571 (1979); Haima et al., Mol. Gen. Genet. 223:185-191 (1990); Weinrauch et al., J. Bacteriol. 154:1077-1087 (1983); and Weinrauch et al., J. Bacteriol. 169:1205-1211 (1987)). In this method, the imported donor plasmid recombines with the homologous region of the resident “helper” plasmid during a process simulating chromosome transformation.

[0108] In addition to commonly used methods, in some embodiments, host cells are directly transformed with a DNA construct or vector containing nucleic acid encoding one or more Bacillus subtilis protease variants described herein (i.e., the intermediate cells are not used for amplification or otherwise treated before introduction into the host cells). Introducing the DNA construct or vector described herein into host cells includes those physical and chemical methods known in the art that introduce nucleic acid sequences (e.g., DNA sequences) into host cells without inserting them into the host genome. Such methods include, but are not limited to, calcium chloride precipitation, electroporation, naked DNA, and liposomes. In another embodiment, the DNA construct or vector is co-transformed with a plasmid without inserting the plasmid. In a further embodiment, a selection marker is deleted from an altered Bacillus strain using methods known in the art (see Stahl et al., J. Bacteriol. [Journal of Bacteriology] 158:411-418 (1984); and Palmeros et al., Gene [Gene] 247:255-264 (2000)).

[0109] In some embodiments, the transformed cells are cultured in a conventional nutrient medium. Suitable specific culture conditions, such as temperature, pH, etc., are known to those skilled in the art and are described in detail in the scientific literature. Some embodiments provide cultures (e.g., cell cultures) containing one or more subtilis protease variants or nucleic acid sequences described herein.

[0110] In some embodiments, host cells transformed with one or more polynucleotide sequences encoding one or more subtilis protease variants described herein are cultured in a suitable nutrient medium under conditions that allow expression of the variants, and the resulting variants are subsequently recovered from the culture. In some embodiments, the variants produced by the cells are recovered from the culture medium by routine procedures, including but not limited to, separating the host cells from the culture medium by centrifugation or filtration, precipitating the protein components of the supernatant or filtrate by means of salt (e.g., ammonium sulfate), and purification by chromatography (e.g., ion exchange, gel filtration, affinity chromatography, etc.).

[0111] In some embodiments, one or more subtilisin protease variants produced by recombinant host cells are secreted into a culture medium. A nucleic acid sequence encoding a purification-enhancing domain can be used to facilitate the purification of said variants. A vector or DNA construct comprising a polynucleotide sequence encoding one or more subtilisin protease variants described herein may further comprise a nucleic acid sequence encoding a purification-enhancing domain that promotes variant purification (see, for example, Kroll et al., DNA Cell Biol. 12:441-53 (1993)). Such purification-enhancing domains include, but are not limited to, metal chelate peptides, such as histidine-tryptophan modules that allow purification on immobilized metals (see Porath, Protein Expr. Purif. 3:263-281

[1992] ), protein A domains that allow purification on immobilized immunoglobulins, and domains utilized in the FLAGS extension / affinity purification system. It was also found that cleavable linker sequences such as factor XA or enterokinase (e.g., sequences available from Invitrogen, San Diego, California) between the purified domain and the heterologous protein can facilitate purification.

[0112] Various methods can be used to determine the production levels of one or more mature Bacillus subtilis protease variants described herein in host cells. Such methods include, but are not limited to, methods utilizing, for example, polyclonal or monoclonal antibodies specific to the protease. Exemplary methods include, but are not limited to, enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), fluorescence immunoassay (FIA), and fluorescence activated cell sorting (FACS). These and other assays are well known in the art (see, for example, Maddox et al., J. Exp. Med. [Journal of Experimental Medicine] 158:1211 (1983)).

[0113] Some other embodiments provide methods for preparing or producing one or more mature subtilisin protease variants described herein. Mature subtilisin protease variants do not include a signal peptide or propeptide sequence. Some methods include preparing or producing one or more subtilisin protease variants described herein in recombinant bacterial host cells (e.g., Bacillus cells, e.g., Bacillus subtilis cells)).

[0177] Further embodiments relate to compositions and methods for treating fabrics (e.g., desizing textiles) using one or more of the Bacillus subtilis protease variants described herein. Fabric treatment methods are well known in the art (see, for example, US 6,077,316). For example, the hand feel and appearance of a fabric can be improved by including contacting the fabric with a solution of the variants described herein. The fabric can be treated with the solution under pressure.

[0178] One or more of the Bacillus subtilis protease variants described herein can be applied during or after weaving of textiles, during the desizing stage, or in one or more other fabric processing steps. During weaving of textiles, the yarn is exposed to considerable mechanical strain. Before weaving on a machine loom, the warp yarns are typically coated with sizing starch or starch derivatives to increase their tensile strength and prevent breakage. One or more of the Bacillus subtilis protease variants described herein can be applied during or after weaving to remove the sizing starch or starch derivatives. After weaving, the variants can be used before further processing of the fabric to remove the sizing coating to ensure uniform and wash-resistant results. One or more Bacillus subtilis protease variants described herein can be used alone or in combination with other desizing chemicals and / or desizing enzymes as detergent additives (e.g., in aqueous compositions) to desizing fabrics (including cotton-containing fabrics). Amylases can also be used in combination with Bacillus subtilis protease variants in compositions and methods for producing a stonewashed appearance on indigo-dyed denim fabrics and garments. For garment production, fabrics can be cut and sewn into garments or apparel, which are then finished. In particular, different enzymatic finishing methods have been developed for denim production. The finishing of denim garments typically begins with an enzymatic desizing step, in which the garment is subjected to proteolytic enzymes to provide softness to the fabric and make the cotton more suitable for subsequent enzymatic finishing steps. One or more Bacillus subtilis protease variants described herein can be used in methods for finishing denim garments (e.g., “biosanding methods”), enzymatic desizing and providing softness to the fabric, and / or finishing methods.

[0209] Expression of BG46 Bacillus subtilis protease variant

[0210] SEQ ID NO:1 provides for Bacillus subtilis protease (BG46) of wild-type Bacillus subtilis Bgi02446. In this study, a BG46 Bacillus subtilis protease variant (SEQ ID NO:2) with substitutions of S039E, S099R, S126A, D127E, and F128G was used as a starting point in the engineered variant with further substitutions and was designated BG46+S039E-S099R-S126A-D127E-F128G. In some studies, the prepared BG46 variant contained a subset of substitutions of S039E, S099R, S126A, D127E, and F128G. All BG46 Bacillus subtilis protease variants were expressed using a DNA fragment comprising, in sequence: a 5' AprE flanking region containing a variant of the Bacillus subtilis rrnIp2 promoter sequence (SEQ ID NO:3) (the Bacillus subtilis rrnIp2 promoter and the engineered variant are more fully described in patent application No. 62 / 772363, filed November 28, 2018); a nucleotide sequence encoding the aprE signal peptide sequence (SEQ ID NO:4); a nucleotide sequence encoding the Bacillus tarda propeptide (SEQ ID NO:5); a sequence corresponding to the gene encoding the mature BG46 Bacillus subtilis protease; a BPN' terminator (SEQ ID NO:6); and a 3' AprE flanking sequence comprising the kanamycin gene expression cassette (SEQ ID NO:7). This DNA fragment was assembled using standard molecular biotechnology. The linear DNA containing the expression cassette was used to transform competent Bacillus subtilis cells of suitable strains.

[0211] The conversion mixture was plated onto LA plates containing 1.6% skim milk and 1.8 ppm kanamycin and incubated overnight at 37°C. Single colonies were picked and grown in Luria broth at 37°C under antibiotic selection.

[0212] For protein expression experiments, transformed cells were grown for 3 days in 96-well MTP culture media (a semi-limited medium enriched with MOP buffer, using urea as the primary nitrogen source, glucose as the primary carbon source, supplemented with 1% soybean peptone for robust cell growth, and containing antibiotic selection) at 32°C, 300 rpm, and 80% humidity in a shaking incubator. After centrifugation and filtration, the clarified culture supernatant containing the target protease was used for assays.

[0213] Example 2

[0214] Measurement

[0215] Protein identification

[0216] The concentration of the BG46 Bacillus subtilis protease variant in the culture supernatant was determined by UHPLC using a Zorbax 300SB-C3 column with a linear gradient of 0.1% trifluoroacetic acid (buffer A) and 0.07% trifluoroacetic acid in acetonitrile (buffer B), and detection at 220 nm. The culture supernatant was diluted with 10 mM NaCl, 0.1 mM CaCl2, and 0.005% Tween 80 before loading onto the column. The protein concentration of the sample was calculated using a standard curve of the purified parental enzyme.

[0217] Protease activity

[0218] The protease activity of the BG46 Bacillus subtilis protease variant was tested by measuring the hydrolysis of the AAPF-pNA synthetic peptide substrate.

[0219] For the AAPF assay, the reagent solution used was: 100 mM Tris pH 8.6, 10 mM CalCl2, 0.005% The working solution was prepared using Tris / Ca buffer and 160 mM suc-AAPF-pNA stock solution in DMSO (Sigma-Aldrich: S-7388). To prepare the working solution, 1 mL of suc-AAPF-pNA stock solution was added to 100 mL of Tris / Ca buffer and mixed. The enzyme sample was added to a microtiter plate (MTP) containing 1 mg / mL suc-AAPF-pNA working solution, and the activity was measured kinetically at 405 nm over 3–5 min at room temperature using a SpectraMax plate reader. Protease activity was expressed as mOD / min.

[0220] Tris-EDTA Stability determination

[0221] The stability of the BG46 subtilis protease variant described herein was measured as follows: the variant was diluted in stress buffer and its proteolytic activity was measured before and after the heating incubation step using AAPF as described above. The temperature and duration of the heating incubation step were selected such that the reference protease showed approximately 15%–30% residual activity. Samples were incubated at 57°C for 5 min in a 384-well thermal cycler. Stability was measured under Tris-EDTA (50 mM Tris pH 9; 5 mM EDTA; 0.005% Tween 80) buffer. The stability PI was obtained by dividing the residual activity of the subtilis protease variant by the residual activity of the parent protease BG46-S039E-S099R-S126A-D127E-F128G. Alternatively, stability results were calculated as a percentage (%) of residual activity for each enzyme sample, calculated by taking the ratio of mOD / min under stress conditions to that under no stress conditions and multiplying by 100.

[0222] Automatic dishwashing and cleaning measurement

[0223] French Caramel Pudding Stains: As described in this article, the cleaning performance of a BG46 Bacillus subtilis protease variant on French caramel pudding stains was tested using a custom-ordered melamine dishwasher monitor (tile) prepared by CFT (in Vlaardingen, Netherlands) and labeled DM10c. The DM10c tiles used in this study were prepared using the same stain, but not at 150°C; instead, they were baked at 140°C for 2 hours. The same stain was used to prepare the commercially available DM10 monitor (a product from Debic.com).

[0224] A DM10c melamine brick was used as a cap and pressed firmly onto a microtiter plate (MTP). A 3 g / L ADW detergent solution was adjusted to a water hardness of 374 ppm, and each enzyme sample was added to the MTP before attaching the melamine brick cap. The volumetric capacity of the MTP and therefore the volume of solution added thereto can vary, but a minimum volume of solution should be added to the MTP to allow contact between the solution and the stained surface. In this example, 300 μL of enzyme-containing detergent was added to each well of an aluminum 96-well MTP. Unless otherwise specified, the MTP was incubated in an Inforrs thermal shaker at 40°C and 250 rpm for 45 min. After incubation, the brick was removed from the MTP, rinsed briefly with tap water, and air-dried.

[0225] Stain removal was quantified by photographing these boards and measuring the RGB values ​​from each stained area using custom software. The percentage of stain removal (%SRI) of the washed bricks was calculated using the RGB values ​​in the following formula:

[0226] %SRI=(ΔE / ΔE) 初始 )*100

[0227] Where ΔE=SQR((R 之后 -R 之前 ) 2 +(G 之后 -G 之前 ) 2 +(B 之后 -B 之前 ) 2 )

[0228] Where ΔE 初始 =SQR((R 白色 -R 之前 ) 2 +(G 白色 -G 之前 ) 2 +(B 白色 -B 之前 ) 2 )

[0229] Cleanliness performance (hereinafter referred to as "cleanliness minus blank") is obtained by subtracting the value of the blank control (enzyme-free) from each sample value. For each condition and BG46 Bacillus subtilis protease variant, the performance index (PI) is calculated by dividing the cleanliness minus blank by the cleanliness of the same concentration of parental protease. The value of the parental protease PI is determined from a standard curve of the parental protease included in the test and fitted to a Langmuir fit or a Hill sigmoid fit.

[0230] Egg Yolk Staining: The cleaning performance of the BG46 Bacillus subtilis protease variant on egg yolk microsamples (PAS-38, Center for Testmaterials BV, Vladivostok, Netherlands) was measured on pre-washed or unwashed samples. To prepare the washed PAS38 samples, 180 μl of 10 mM CAPS buffer (pH 11) was added to the MTP containing the PAS38 microsamples. The plates were sealed and incubated in an iEMS incubator at 60 °C and 1100 rpm for 30 min with shaking. After this incubation, the buffer was removed, and the samples were rinsed with deionized water to remove any residual buffer. The plates were then air-dried before use for performance assays. Before adding the enzyme, the microsample plates were packed with a 3 g / L ADW detergent solution with a water hardness of 374 ppm, resulting in a final enzyme concentration between 0.05 and 10 ppm.

[0231] After incubating PAS-38 samples with detergent and enzyme at 40°C for 30 minutes, aliquots were transferred to empty MTP plates, and absorbance was read at 405 nm using a SpectraMax plate reader. Absorbance results were obtained by subtracting the value of the blank control (enzyme-free) from each sample value (hereinafter referred to as "Absorbance minus blank"). For each condition and BG46 Bacillus subtilis protease variant, the performance index (PI) was calculated by dividing the absorbance minus blank by the absorbance of the same concentration of the parent protease BG46+S039E-S099R-S126A-D127E-F128G (SEQ ID NO:2).

[0232] Detergent

[0233] Various detergent formulations were used, as listed below. Automatic dishwashing (ADW) cleaning tests were conducted using the following detergents at final concentrations shown in parentheses: GSM-B detergent (3 g / L) (enzyme-free GSM-B phosphate-free ADW detergent, from WFK Testgewebe GmbH, Brüggen, Germany) www.testgewebe.de Purchase (Table 1 shows the composition) and MGDA detergent (3g / L) (Table 2 shows the composition).

[0237] Automatic dishwashing performance and stability of BG46 Bacillus subtilis protease variant

[0238] In most cases, the Bacillus gibsiensis Bgi02446 subtilis protease variant (BG46) (SEQ ID NO:2) with substitutions S039E-S099R-S126A-D127E-F128G was used as the parent for evaluating additional substitutions, while in some cases, the wild-type parent of the Bacillus gibsiensis Bgi02446 subtilis protease variant (BG46) was used as the reference enzyme. Example 1 describes the expression of these proteins. The ADW cleaning performance of these BG46 subtilis protease variants on egg (PAS-38) and crème brûlée (DM10c) technical stains, and the stability (Tris / EDTA) of the variants, were measured using the detergents and assays described in Example 2, and the results are reported in Tables 3, 4, 5, and 6. Cleanliness benefits and stability are expressed as PI values ​​relative to the parental enzymes BG46+S039E-S099R-S126A-D127E-F128G in Tables 3, 4, and 6. Table 5 shows data for variants compared to the wild-type parent BG46, where cleanliness benefits are expressed as PI values ​​and stability as a percentage of residual activity.
