Description

[Technical Field]

[0001] (Reference to sequence listing) The present specification contains a Sequence Listing in computer readable form, which is incorporated herein by reference.

[0002] FIELD OF THE INVENTION The present invention relates to detergent compositions and cleaning methods comprising specific DNase enzymes with improved properties, such as improved stability in detergents and / or during storage. The compositions are preferably laundry detergent compositions and / or hard surface cleaning compositions, such as dishwashing compositions, suitable for use in hand or automatic washing. The invention also relates to methods for making such detergent compositions and methods for cleaning surfaces by hand and / or in an automatic washing machine, as well as methods for using such compositions. [Background technology]

[0003] Hard surfaces and fabrics are exposed to soils and microorganisms from the environment and personal soils. Microorganisms contained in accumulated soil can promote the formation of soils of microbial origin, such as biofilm soils. For example, in laundry, biofilm-producing bacteria include Acinetobacter, Aeromicrobium, Brevundimonas, Microbacterium, Micrococcus luteus, Pseudomonas, Staphylococcus epidermidis, and Stenotrophomonas. Biofilms contain a matrix of extracellular polymeric substances (EPS): a polymeric mixture generally containing extracellular DNA, proteins, and polysaccharides. These stains are sticky, difficult to remove, and tend to induce further adhesion of other soils. Therefore, household care-related stains are complex and may contain particulates, proteins, starches, oils, and EPS. As a result, stain removal is also complex, and various enzymes, including deoxyribonuclease (DNase) enzymes, can be useful.

[0004] Detergent compositions containing DNase are already known. However, to be useful in household cleaning processes, enzymes such as DNase must be stable in the detergent composition, for example, in the presence of detergent ingredients such as surfactants, builders, and / or bleaches. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention provides detergent compositions containing DNase enzymes with good stability. [Means for solving the problem]

[0006] The present invention provides a detergent composition comprising a polypeptide having DNase activity and good stability in the detergent composition, and a cleaning adjuvant, wherein the polypeptide is a DNase variant comprising at least one, and preferably two or more, substitutions selected from the group consisting of N61D, T65I, T65V, S82R, K107Q, T127S, T127V, G149N, S164D, and L181S compared to the polypeptide of SEQ ID NO: 1, wherein the variant has at least 60% sequence identity to SEQ ID NO: 1 and has DNase activity.

[0007] The present invention also provides a method of treating a surface, preferably a fabric, the method comprising contacting the surface with an aqueous wash solution comprising a polypeptide having DNase activity, the polypeptide being a DNase variant comprising at least one substitution, and typically two or more substitutions, selected from the group consisting of N61D, T65I, T65V, S82R, K107Q, T127S, T127V, G149N, S164D, and L181S compared to the polypeptide of SEQ ID NO: 1, the variant comprising a polypeptide having at least 60% sequence identity to SEQ ID NO: 1, and a cleaning adjunct.

[0008] Preferably, the surface is contacted with the aqueous cleaning solution at a temperature of 60° C. or less, or more preferably at a temperature of 40° C. or less or 35° C. or less, and most preferably at a temperature of 30° C. or less or even 30° C. or less, and (iii) rinsing the surface. The compositions and methods herein are particularly useful for treating surfaces, for example, fabrics made from synthetic or natural materials, including blended fabrics such as cotton, wool, silk, polyester, nylon, elastane, or polycotton, and / or hard surfaces such as dishware.

[0009] The present invention also relates to the use of a composition or method as described above for improved cleaning, such as deep cleaning; maintaining or improving the whiteness of fabrics; improved stain removal from surfaces such as fabrics; reducing or eliminating malodors from surfaces such as fabrics; preventing fabrics from wrinkling; improving fabric drying; preventing soil redeposition, preventing and / or reducing surface stickiness, pre-treating stains, and preventing and / or reducing the adhesion of soils to surfaces.

[0010] The present invention also relates to a method of making a detergent composition comprising preparing a polypeptide having DNase activity as described herein and mixing it with a cleaning adjunct.

[0012] definition The term "clade" refers to a group of polypeptides clustered together based on homologous characteristics derived from a common ancestor. A clade of polypeptides can be visualized as a phylogenetic tree, where a clade is a group of polypeptides consisting of a common ancestor and all of its direct descendants. Polypeptides that form a group, e.g., a clade, shown in a phylogenetic tree often share common characteristics and are more closely related than other polypeptides that do not belong to the clade.

[0013] The term "deep cleaning" refers to the disruption or removal of components of organic matter, such as biofilms, such as polysaccharides, proteins, DNA, dirt, or other components present in organic matter.

[0014] The terms "DNase," "DNase variant," or "DNase parent" refer to a polypeptide having DNase activity (i.e., deoxyribonuclease activity) that catalyzes the hydrolytic cleavage of phosphodiester bonds in DNA, thereby degrading DNA. DNases belong to the esterase subgroup (EC number 3.1) of hydrolases. DNases are classified, for example, in EC 3.1.11, EC 3.1.12, EC 3.1.15, EC 3.1.16, EC 3.1.21, EC 3.1.22, EC 3.1.23, EC 3.1.24, and EC 3.1.25, as well as EC 3.1.21.X (where X = 1, 2, 3, 4, 5, 6, 7, 8, or 9). The terms "DNase" and "polypeptide having DNase activity" may be used interchangeably throughout this application. For purposes of the present invention, deoxyribonuclease activity can be determined according to the procedure described in the assay below. The DNase variants of the present invention preferably have at least one improved property compared to the parent DNase. In one embodiment, the DNase variants have improved stability, e.g., improved storage stability in a detergent composition, compared to the parent DNase. Preferably, the DNase variants have a half-life improvement factor (T1 / 2 IF, or HIF) of at least 1.1, more preferably at least 1.2, preferably at least 1.5, more preferably at least 2, e.g., at least 3, after storage in a liquid detergent, as compared to the half-life of a reference DNase, e.g., the DNase of SEQ ID NO: 1 and / or the parent DNase, as determined, e.g., as described in Example 3 herein. The half-life improvement factor of a DNase variant is calculated as the half-life of the DNase variant relative to the half-life of the reference DNase.

[0015] An "effective amount" with respect to an enzyme refers to the amount of enzyme necessary to achieve the enzymatic activity required for a particular application, e.g., in a given detergent composition. Such an effective amount is readily ascertainable by one of ordinary skill in the art and is based on many factors, including the specific enzyme used, the cleaning application, the specific composition of the detergent composition, and whether a liquid or dry (e.g., granule, bar) composition is required. The term "effective amount" of a DNase variant refers to the amount of said DNase variant that achieves a desired level of enzymatic activity, e.g., in a given detergent composition.

[0016] The term "expression" includes any step involved in producing a variant, including, but not limited to, transcription, post-transcriptional modification, translation, post-translational modification, and secretion.

[0017] The term "expression vector" refers to a linear or circular DNA molecule that contains a polynucleotide encoding a variant, operably linked to additional nucleotides that effect its expression.

[0018] The term "fabric" includes any textile material. Thus, the term is intended to encompass fabrics, yarns, fibers, nonwoven materials, natural materials, synthetic materials, and any other textile material, in addition to garments.

[0019] The term "host cell" refers to any cell type that is amenable to transformation, transfection, transduction, etc. with a nucleic acid construct or expression vector comprising a polynucleotide of the invention. The term "host cell" encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication.

[0020] The term "improved properties" refers to characteristics associated with a variant that are improved compared to a parent and / or DNase polypeptide having SEQ ID NO: 1, or compared to a DNase having the same amino acid sequence as said variant but lacking the modifications defined herein at one or more of the above-specified positions. Such improved properties include, but are not limited to, stability, such as detergent stability, e.g., detergent storage stability, and cleaning performance, e.g., deep cleaning effect, which may include de-adhesion effect. The DNase variant preferably has improved stability, in particular improved detergent storage stability, compared to the polypeptide of SEQ ID NO: 1.

[0021] The term "improved DNase activity" is defined herein as a change in DNase activity relative to the activity of a parent DNase, for example, due to increased catalysis of the hydrolytic cleavage of phosphodiester bonds in DNA, such as compared to a DNase variant having SEQ ID NO: 1.

[0022] The term "improved cleaning performance" includes, but is not limited to, the term "deep cleaning effect." Improved performance, e.g., deep cleaning performance, of the DNase variants of the present invention is measured compared to the DNase parent, e.g., the DNase set forth in SEQ ID NO: 1 or SEQ ID NO: 27. Improved performance, e.g., deep cleaning performance, can be expressed as the remission value of the stained swatch. After washing and rinsing, the swatches are laid flat and allowed to air dry overnight at room temperature. All washed swatches are evaluated the same day after washing. Light reflectance evaluation of the swatches is performed using a Macbeth Color Eye 7000 reflectance spectrometer with a very small aperture. Measurements are performed without ultraviolet light in the incident light, and the reflectance at 460 nm is extracted. A positive reaction indicates that the stain has been removed. This may include stains that adhere to the fabric due to, for example, a sticky biofilm layer.

[0023] 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. The N-terminus of a mature polypeptide can be determined experimentally based on EDMAN N-terminal sequencing data and Intact MS data. It is known in the art that a host cell can produce a mixture of two or more different mature polypeptides (i.e., with different C-terminal and / or N-terminal amino acids) expressed by the same polynucleotide.

[0024] The term "mature polypeptide coding sequence" refers to a polynucleotide that encodes a mature polypeptide having DNase activity.

[0025] The term "nucleic acid construct" refers to a nucleic acid molecule, either single-stranded or double-stranded, that has been isolated from a naturally occurring gene or modified to contain segments of nucleic acid that are not otherwise found in nature, or that is synthetic. The term nucleic acid construct is synonymous with the term "expression cassette" when the nucleic acid construct contains the control sequences required for expression of a coding sequence of the present invention.

[0026] The term "operably linked" refers to a configuration in which control sequences are positioned in appropriate relation to a coding sequence of a polynucleotide so that the control sequences direct the expression of the coding sequence.

[0027] The terms "parent DNase," "DNase parent," or "precursor DNase" may be used interchangeably. In the context of the present invention, a "parent DNase" should be understood as a DNase in which at least one modification is made in the amino acid sequence to generate a DNase variant with an amino acid sequence that is less than 100% identical to the DNase sequence in which the modification is made. Thus, a parent is a DNase that has an identical amino acid sequence compared to the variant but does not have a modification at one or more of the specified positions. The DNase parent may be a DNase having at least 60%, at least 61%, at least 62%, at least 63%, at least 64%, at least 65%, at least 66%, at least 67%, at least 68%, at least 69%, at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, 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% identity to the polypeptide set forth in SEQ ID NO:1.

[0028] The term "relevant washing conditions" is used herein to refer to the conditions used in homes in the detergent market segment, in particular washing temperature, time, washing machine, detergent concentration, detergent type, and water hardness.

[0029] The term "stability" includes storage stability and stability during use, e.g., during the washing process, and reflects the stability of the DNase variants of the present invention as a function of time, e.g., how much activity is retained when the DNase variant is maintained in a detergent or detergent solution. Stability is affected by many factors, e.g., pH, temperature, detergent composition, e.g., amount of builder, surfactant, etc. DNase stability can be measured as described in Example 3. The terms "improved stability" or "increased stability" are defined herein as a variant DNase that exhibits increased stability in solution, e.g., a detergent solution, relative to the stability of the parent DNase and / or relative to SEQ ID NO: 1. "Improved stability" and "increased stability" can refer to detergent stability during storage or use ("washing stability").

[0030] The term "variant" refers to a polypeptide that has DNase activity and contains a substitution at one or more positions as defined elsewhere herein. A substitution refers to replacing an amino acid occupying a position with a different amino acid; a deletion refers to removing an amino acid occupying a position; and an insertion refers to adding amino acids, e.g., 1 to 10 amino acids, preferably 1 to 3 amino acids, adjacent to the amino acid occupying a position. Variants of the invention have at least 20%, e.g., at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 100%, of the DNase activity of the polypeptide of SEQ ID NO: 1.

[0031] The term "washing solution" refers to an aqueous solution containing a DNase variant and a washing adjuvant as described herein.

[0032] The terms "water hardness" or "hardness" or "dH" or "°dH" as used herein refer to the German scale of hardness, where one degree is defined as 10 milligrams of calcium oxide per liter of water.

[0033] Mutant designation arrangements Unless otherwise indicated, the polypeptide disclosed in SEQ ID NO: 1 is used for the purpose of the present invention to determine the corresponding amino acid residue in another DNase. The amino acid sequence of another DNase is aligned with the polypeptide disclosed in SEQ ID NO: 1, and based on the alignment, the amino acid position number corresponding to any amino acid residue in the polypeptide disclosed in SEQ ID NO: 1 is determined using, for example, the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48:443-453) implemented in the Needle program, preferably version 5.0.0 or higher, of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16:276-277). The parameters used are a gap opening penalty of 10, a gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix.

[0034] Identification of corresponding amino acid residues in other DNases can be achieved using, but is not limited to, MUSCLE (multiple sequence comparison by log prediction, version 3.5 or higher; Edgar, 2004, Nucleic Acids Research 32:1792-1797), MAFFT (version 6.857 or higher; Katoh and Kuma, 2002, Nucleic Acids Research 30:3059-3066; Katoh et al., 2005, Nucleic Acids Research 33:511-518; Katoh and Toh, 2007, Bioinformatics 23:372-374; Katoh et al., 2009, Methods in Molecular Biology 537:39-64; Katoh and Toh, 2010, Bioinformatics 26:1899-1900), and EMBOSS EMMA employing It can be determined by aligning multiple polypeptide sequences using several computer programs, including EMBOSS EMMA using ClustalW (1.83 or higher; Thompson et al., 1994, Nucleic Acids Research 22:4673-4680).

[0035] Other pairwise sequence comparison algorithms may be used when other enzymes diverge from the polypeptide of SEQ ID NO: 1, such that traditional sequence-based comparisons fail to detect these relationships (Lindahl and Elofsson, 2000, J. Mol. Biol. 295:613-615). Greater sensitivity in sequence-based searches can be achieved by using search programs that utilize probabilistic representations (profiles) of polypeptide families to search databases. For example, the PSI-BLAST program generates profiles through an iterative database search process, allowing the detection of distant homologs (see Atschul et al., 1997, Nucleic Acids Res. 25:3389-3402). Even greater sensitivity can be achieved when a family or superfamily of polypeptides has more than one representation in a protein structure database. Programs such as GenTHREADER (Jones, 1999, J. Mol. Biol. 287:797-815; McGuffin and Jones, 2003, Bioinformatics 19:874-881) use information from a variety of sources (PSI-BLAST, secondary structure prediction, structural alignment profiles, and solvate potential) as input to neural networks that predict the structural fold of a query sequence. Similarly, the method of Gough et al., 2000, J. Mol. Biol. 313:903-919 can be used to align sequences of unknown structure with superfamily models present in the SCOP database. These alignments can then be used to generate homology models of the polypeptide, and such models can be assessed for accuracy using a variety of tools developed for that purpose.

[0036] For proteins of known structure, several tools and resources are available for searching and creating structural alignments. For example, the SCOP superfamily of proteins has been structurally aligned, and these alignments are accessible and downloadable. Various algorithms, such as distance alignment matrices (Holm and Sander, 1998, Proteins 33:88-96) or combinatorial extension (Shindyalov and Bourne, 1998, Protein Engineering 11:739-747), can be used to align two or more protein structures; implementations of these algorithms can then be used to query structural databases for the target structure to find potential structural homologs (e.g., Holm and Park, 2000, Bioinformatics 16:566-567).

[0037] Because different amino acids may be present at a given position depending on the parent selected for the variant, the amino acid positions are designated as #1, #2, etc. in the definitions below. In describing the variants of the present invention, the following nomenclature is adopted for ease of reference: The generally accepted IUPAC one-letter or three-letter amino acid abbreviations are used.

[0038] Substitutions: For amino acid substitutions, the following nomenclature is used: original amino acid, position, substituted amino acid. Thus, a substitution of valine with alanine at position #1 is designated "Val#1Ala" or "V#1A." Multiple mutations are separated by a plus sign ("+") or a comma (,), e.g., "Val#1Ala+Pro#2Gly" or V#1A,P#2G" represents the substitution of valine (V) and proline (P) with alanine (A) and glycine (G) at positions #1 and #2, respectively. When more than one amino acid can be substituted at a given position, these are listed in parentheses, such as [X] or {X}. Thus, if both Trp and Lys can be substituted for the amino acid occupying position #1, this is designated as X#1{W,K}, X#1[W,K], or X#1[W / K] (where X represents the amino acid residue present at that position in the parent DNase, e.g., the DNase set forth in SEQ ID NO: 1 or a DNase with at least 60% identity thereto). In some cases, the variant can also be designated #1{W,K} or X#2P, indicating that the substituted amino acid varies depending on the parent.

[0039] For convenience, SEQ ID NO: 1 is used to number the substitutions and other mutations disclosed herein, and therefore the amino acid at the corresponding position in SEQ ID NO: 1 will be indicated, for example, as T65V. However, it will be clear to those skilled in the art that DNase variants containing T65V are not limited to parent DNases having a threonine at the position corresponding to position 65 in SEQ ID NO: 1. For example, in a parent DNase having an asparagine at position 65, those skilled in the art would change the mutation designated T65V to N65V. If the parent DNase has an alanine at position 65, those skilled in the art would recognize that the parent DNase is unchanged at this position. The same applies to deletions and insertions described below. This may also be indicated using "X," defined as any of the 20 naturally occurring amino acids, as the original amino acid; for example, X65V means that any amino acid residue other than V at position 65 is changed to V.

[0040] Deletions: For amino acid deletions, use the following nomenclature: original amino acid, position, * Thus, the deletion of valine at position #1 is expressed as "Val#1 * " or "V#1 * " Multiple deletions are represented as, for example, "Val#1 * +Pro#2 * " or V#1 * ,P#2 * " and are separated by a plus sign ('+') or a comma.

[0041] Insertion: For example, the insertion of an additional amino acid residue, such as a lysine, after Val#1 can be indicated by Val#1ValLys or V#1VK. Alternatively, the insertion of an additional amino acid residue, such as a lysine, after V#1 can be indicated by * For example, when more than one amino acid residue, such as Lys and Gly, is inserted after #1, this can be represented as Val#1ValLysGly or V#1VKG. In such cases, the inserted amino acid residue may be numbered by adding a lower case letter to the position number of the amino acid residue preceding the inserted amino acid residue, in this example: * #1aK * #1bG.

[0042] Multiple modifications: Variants containing multiple modifications are separated by a plus sign ("+") or a comma (,), e.g., "Val#1Trp+Pro#2Gly" or "V#1W,P#2G" or "V#1W+P#2G" represent substitutions of tryptophan and glycine for valine and proline at positions #1 and #2, respectively, as described above.

[0043] Different modifications: When different modifications can be introduced at a position, they may be separated by a comma, for example, "Val#1Trp,Lys" or V#1W,K represents the substitution of valine with tryptophan or lysine at position #1. Thus, "Val#1Trp,Lys+Pro#2Asp" represents the following variants: "Val#1Trp+Pro#2Asp", "Val#1Lys+Pro#2Asp" or V#1W,K+P#2D.

[0044] Different alterations may also be indicated using the nomenclature [IV] or [I / V], meaning that the amino acid at this position may be isoleucine (Ile, I) or valine (Val, V). Similarly, the nomenclature [LVI] and [L / V / I] means that the amino acid at this position may be leucine (Leu, L), valine (Val, V), or isoleucine (Ile, I), as well as other combinations described herein. For example, T65I / V refers to the substitution of T at position 65 with either I or V. DETAILED DESCRIPTION OF THE INVENTION

[0112] In another embodiment of this aspect, the DNase variant comprises the substitution S164D, wherein the variant has at least 60% sequence identity to SEQ ID NO: 1, e.g., at least 70%, at least 80%, at least 85%, at least 90%, or at least 95% sequence identity, and has DNase activity. The variant may further comprise one or more additional substitutions, for example, (i) one or more substitutions selected from the group consisting of N61D, T65I, T65V, S82R, K107Q, T127S, T127V, G149N, and L181S, and / or (ii) one or more substitutions selected from the group consisting of Q14R, Q14W, K21L, P25S, L33K, Q48D, D56I, D56L, S66Y, S68L, Y77T, S102Y, S106A, R109Q, R109T, D116S, D116W, T171W, L181T, and L181W. The DNase variant may further comprise one or more substitutions selected from the group consisting of I1T, Y13S, P22T, P25S, L27S, P39S, G42S, W57S, V59S, L76V, Y77T, R109Q, D116S, P144S, H147A, L167S, D175G, and L181S.

[0113] In a further aspect, the present invention provides a polypeptide having DNase activity comprising or consisting of the amino acid sequence of SEQ ID NO:1.

[0114] As noted above, the DNase variant has at least 60% sequence identity to SEQ ID NO: 1, for example at least 70%, at least 75%, at least 80%, at least 85%, or at least 90% sequence identity to SEQ ID NO: 1. The DNase variant may have at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 97%, at least 98%, or 99% sequence identity to SEQ ID NO: 1.

[0115] Thus, DNase variants may comprise more than two modifications, typically substitutions, such as 3, 4, 5, 6, 7, 8, 9 or 10 modifications compared to SEQ ID NO: 1. In other embodiments, DNase variants may comprise more than 10 modifications, typically substitutions, for example up to 15 or up to 20 modifications, compared to SEQ ID NO: 1.

[0116] Preferably, the DNase variants have improved properties, which may be, for example, improved stability in detergents, improved stability during washing, and / or improved thermal stability. Preferably, the DNase variants have improved stability, detergent stability, in particular improved detergent storage stability. Furthermore, the variants preferably have substantially maintained, or more preferably improved, relative cleaning performance compared to a reference DNase, which may be, for example, the DNase of SEQ ID NO: 1 or SEQ ID NO: 27.

[0117] Variants may contain additional mutations to those listed above, which preferably do not significantly alter the improved properties of the variant DNase and may, for example, be conservative substitutions.

[0118] Examples of conservative substitutions are those within the group of 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 low molecular weight amino acids (glycine, alanine, serine, threonine, and methionine). Amino acid substitutions that generally do not change the specific activity are known in the art and are described, for example, in H. Neurath and R.L. Hill, 1979, The Proteins, Academic Press, New York. Common substitutions 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.

[0119] Essential amino acids in a polypeptide can be identified by procedures 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, single alanine mutations are introduced at every residue in the molecule, and the resulting mutant molecules are tested for DNase activity to identify amino acid residues important for the molecule's activity. See also Hilton et al., 1996, J. Biol. Chem. 271:4699-4708. Active sites of enzymes or other biological interactions can also be determined by physical analysis of the structure, as determined by techniques such as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutations of amino acids at putative contact sites. See, e.g., de Vos et al., 1992, Science 255:306-312; Smith et al., 1992, J. Mol. Biol. 224:899-904; Wlodaver et al., 1992, FEBS Lett. 309:59-64.

[0121] Preferably, the DNase parent is obtained from a microorganism and the DNase is a microbial enzyme. The DNase is preferably of fungal or bacterial origin.

[0122] The DNase parent is preferably obtained from the genus Bacillus, such as Bacillus sibii, Bacillus strain 62451, Bacillus horikoshii, Bacillus strain 16840, Bacillus strain 62668, Bacillus strain 13395, Bacillus hornekiae, Bacillus strain 11238, Bacillus idriensis, Bacillus strain 62520, Bacillus argicola, Bacillus vietnamensis, Bacillus huajingpoensis, Bacillus indicus, Bacillus marisflavi, Bacillus luciferensis, Bacillus strain SA2-6, etc.

[0123] The DNase parent is preferably a DNase containing the conserved motif [D / M / L][S / T]GYSR[D / N] (SEQ ID NO: 25) or ASXNRSKG (SEQ ID NO: 26), and belongs to a group of DNases within the GYS clade that share similar structural and functional properties. See, for example, WO 2017 / 060475. DNases of the GYS clade are preferably obtained from the genus Bacillus.

[0124] In one embodiment, the variant is a variant of a DNase parent of the GYS-clade having DNase activity, optionally wherein the parent comprises one or both motifs [D / M / L][S / T]GYSR[D / N] (SEQ ID NO: 25), ASXNRSKG (SEQ ID NO: 26), or the parent is a variant of a DNase polypeptide comprising one or both of these motifs, for example a variant of a DNase polypeptide obtained from a naturally occurring microorganism, wherein the polypeptide is a) a polypeptide having at least 60%, at least 70%, at least 80%, at least 85%, 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 to the polypeptide set forth in SEQ ID NO: 1;

[0125] Polypeptides with DNase activity and containing motifs of the GYS clade have particularly good deep cleaning properties, and compositions containing such DNases are therefore particularly effective in removing or reducing organic matter, such as soils of microbial origin, from items such as textiles or hard surfaces.

[0126] In preferred embodiments, the parent has at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to the polypeptide set forth in SEQ ID NO: 1 which has DNase activity.

[0127] In some embodiments, the parent comprises or consists of the amino acid sequence of SEQ ID NO:1.

[0128] Preparation of variants The present invention also relates to a method for making a detergent composition comprising obtaining a DNase variant having at least one improved property compared to the parent DNase, e.g., compared to the polypeptide set forth in SEQ ID NO: 1, and mixing with a cleaning adjunct.

[0129] Thus, this aspect relates to a method of making a detergent composition, the method comprising: (i) a) obtaining a DNase variant, comprising introducing into a parent DNase having at least 60% sequence identity to SEQ ID NO: 1 two or more substitutions selected from the group consisting of N61D, T65I, T65V, S82R, K107Q, T127S, T127V, G149N, S164D, and L181S (numbering based on SEQ ID NO: 1); (ii) recovering the variant, wherein the variant has DNase activity; (iii) mixing with a cleaning adjunct.

[0130] It will be appreciated that the method for obtaining a DNase variant may further comprise the introduction of any of the other substitutions or combinations of substitutions described above. For example, the method for obtaining a DNase variant may further comprise the introduction of at least one substitution selected from the group consisting of Q14R, Q14W, K21L, P25S, L33K, Q48D, D56I, D56L, S66Y, S68L, Y77T, S102Y, S106A, R109Q, R109T, D116S, D116W, T171W, L181T, and L181W. The method may also include the introduction of at least one substitution selected from the group consisting of I1T, Y13S, P22T, P25S, L27S, P39S, G42S, W57S, V59S, L76V, Y77T, R109Q, D116S, P144S, H147A, L167S, and D175G.

[0131] In a preferred embodiment, the parent DNase has at least 80% sequence identity to the polypeptide of SEQ ID NO: 1, such as at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% sequence identity to the polypeptide of SEQ ID NO: 1. In another aspect, the parent DNase has the amino acid sequence of SEQ ID NO: 1.

[0132] In other embodiments, the variant may be based on a parent DNase selected from those mentioned above, i.e. a polypeptide selected from the group consisting of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, SEQ ID NO:11, SEQ ID NO:12, SEQ ID NO:13, SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, SEQ ID NO:26, or SEQ ID NO:27, or a polypeptide having at least 60%, at least 70%, at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, at least 93% identity, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or 99% sequence identity to any of these.

[0133] Variants can be prepared by procedures well known in the art, such as those described below.

[0134] Site-directed mutagenesis is a technique for introducing mutations at one or more defined sites in a parent encoding polynucleotide. Site-directed mutagenesis can be performed in vitro by PCR, involving the use of oligonucleotide primers containing the desired mutations. Site-directed mutagenesis can also be performed in vitro by cassette mutagenesis, which involves cleaving a site in a plasmid containing a parent encoding polynucleotide with a restriction enzyme, followed by ligation of an oligonucleotide containing the mutation in the polynucleotide. Typically, the restriction enzymes used to digest the plasmid and the oligonucleotide are the same, allowing the cohesive ends of the plasmid and the insert to be ligated together. See, for example, Scherer and Davis, 1979, Proc. Natl. Acad. Sci. USA 76:4949-4955 and Barton et al., 1990, Nucleic Acids Res. 18:7349-4966.

[0135] Site-directed mutagenesis can also be performed in vivo by methods known in the art (see, e.g., U.S. Patent Application Publication No. 2004 / 0171154; Storici et al., 2001, Nature Biotechnol. 19:773-776; Kren et al., 1998, Nat. Med. 4:285-290; and Calissano and Macino, 1996, Fungal Genet. Newslett. 43:15-16).

[0136] Synthetic gene construction involves the in vitro synthesis of polynucleotide molecules designed to encode a polypeptide of interest. Gene synthesis can be performed using several techniques, such as the multiplexed microchip-based technique described by Tian et al. (2004, Nature 432:1050-1054), in which oligonucleotides are synthesized and assembled on a photoprogrammable microfluidic chip, and similar techniques.

[0137] Single or multiple amino acid substitutions, deletions, and / or insertions can be made and tested using known mutagenesis, recombination, and / or shuffling methods followed by associated screening procedures such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241:53-57; Bowie and Sauer, 1989, 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; Ibid. 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).

[0138] Mutagenesis / shuffling methods may be combined with high-throughput automated screening methods to detect the activity of cloned mutant polypeptides expressed by host cells (Ness et al., 1999, Nature Biotechnology 17:893-896). Mutant DNA molecules encoding active polypeptides can be recovered from the host cells and rapidly sequenced using standard methods in the art. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide.

[0139] Semi-synthetic gene construction is achieved by combining aspects of synthetic gene construction, and / or site-directed mutagenesis, and / or random mutagenesis, and / or shuffling. Semi-synthetic construction is exemplified by processes that utilize synthesized polynucleotide fragments combined with PCR technology. In this manner, defined regions of a gene can be synthesized de novo, while other regions may be amplified using site-directed mutagenesis primers, and still other regions may be subjected to error-prone or non-error-prone PCR amplification. Subsequent polynucleotide sequences may then be shuffled.

[0140] Nucleic Acid Constructs Disclosed herein are nucleic acid constructs comprising a polynucleotide encoding a variant of the invention operably linked to one or more control sequences that direct the expression of the coding sequence in a suitable host cell under conditions compatible with the control sequences.

[0141] Polynucleotides can be manipulated in a variety of ways to provide for expression of a polypeptide. Manipulation of the polynucleotide prior to insertion into a vector may be desirable or necessary, depending on the expression vector. Techniques for modifying polynucleotides utilizing recombinant DNA methods are well known in the art.

[0142] The control sequence may be a promoter, a polynucleotide recognized by a host cell for expression of a polynucleotide encoding a polypeptide of the invention. A promoter contains transcriptional control sequences that mediate expression of the polypeptide. The promoter may be any polynucleotide that shows transcriptional activity in a host cell, including mutated, truncated, and hybrid promoters, and may be derived from genes encoding extracellular or intracellular polypeptides that are homologous or heterologous to the host cell.

[0143] Examples of suitable promoters for directing transcription of the nucleic acid constructs of the present invention in bacterial host cells include the Bacillus amyloliquefaciens alpha-amylase gene (amyQ), the Bacillus licheniformis alpha-amylase gene (amyL), the Bacillus licheniformis penicillinase gene (penP), the Bacillus stearothermophilus maltogenic amylase gene (amyM), the Bacillus subtilis levansucrase gene (sacB), the Bacillus subtilis xylA and xylB genes, the Bacillus thuringiensis cryIIIA gene (Agaisse and Lereclus, 1994, Molecular Microbiology 13:97-107), the E. coli lac operon, and the E. coli trc promoter (Egon et al., 1988, Gene 69:301-315), the Streptomyces coelicolor agarase gene (dagA), and the prokaryotic beta-lactamase gene (Villa-Kamaroff et al., 1978, Proc. Natl. Acad. Sci. USA 75:3727-3731), as well as the tac promoter (DeBoer et al., 1983, Proc. Natl. Acad. Sci. USA 80:21-25). Additional promoters are described in "Useful proteins from recombinant bacteria" by Gilbert et al., 1980, Scientific American 242:74-94, and by Sambrook et al., 1989, supra.

Other promoters are described in U.S. Patent No. 6,011,147.

[0145] In yeast hosts, useful promoters are obtained from the genes for Saccharomyces cerevisiae enolase (ENO1), Saccharomyces cerevisiae galactokinase (GAL1), Saccharomyces cerevisiae alcohol dehydrogenase / glyceraldehyde-3-phosphate dehydrogenase (ADH1, ADH2 / GAP), Saccharomyces cerevisiae triosephosphate isomerase (TPI), Saccharomyces cerevisiae metallothionein (CUP1), and Saccharomyces cerevisiae 3-phosphoglycerate kinase. Other useful promoters for yeast host cells are described by Romanos et al., 1992, Yeast 8:423-488.

[0146] The control sequence may also be a transcription terminator recognized by a host cell to terminate transcription. The terminator is operably linked to the 3' end of the polynucleotide encoding the polypeptide. Any terminator that functions in the host cell may be used in the present invention.

[0147] Preferred terminators for bacterial host cells are obtained from the genes for Bacillus clausii alkaline protease (aprH), Bacillus licheniformis alpha-amylase (amyL), and Escherichia coli ribosomal RNA (rrnB). Other terminators can be obtained from the genes for Bacillus nidulans acetamidase, Bacillus nidulans anthranilate synthase, Bacillus niger glucoamylase, Bacillus niger alpha-glucosidase, or Bacillus sibirica TAKA amylase.

[0148] Preferred terminators for filamentous fungal host cells include Aspergillus nidulans acetamidase, Aspergillus nidulans anthranilate synthase, Aspergillus niger glucoamylase, Aspergillus niger α-glucosidase, Aspergillus oryzae TAKA amylase, Fusarium oxysporum trypsin-like protease, Trichoderma reesei β-glucosidase, Trichoderma reesei cellobiohydrolase I, Trichoderma reesei β-glucosidase ... The genes for lobiohydrolase 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 are obtained.

[0149] Preferred terminators for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase, Saccharomyces cerevisiae cytochrome C (CYC1), and Saccharomyces cerevisiae glyceraldehyde-3-phosphate dehydrogenase. Other useful terminators for yeast host cells are described by Romanos et al., 1992, supra.

[0150] The regulatory sequence may also be an mRNA stabilizing region downstream of the gene's promoter and upstream of the coding sequence, which increases expression of the gene. Examples of suitable mRNA stabilizing regions are obtained from the Bacillus thuringiensis cryIIIA gene (WO 94 / 25612) and the Bacillus subtilis SP82 gene (Hue et al., 1995, Journal of Bacteriology 177:3465-3471).

[0151] The control sequence may also be a leader, a non-translated region of an mRNA that is important for translation by the host cell. The leader is operably linked to the 5' terminus of the polynucleotide encoding the polypeptide. Any leader that is functional in the host cell may be used.

[0152] Preferred leaders for filamentous fungal host cells are obtained from the genes for Bacillus sibiricus TAKA amylase and Bacillus nidulans triose phosphate isomerase.

[0153] Suitable leaders for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae 3-phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, and Saccharomyces cerevisiae alcohol dehydrogenase / glyceraldehyde-3-phosphate dehydrogenase (ADH2 / GAP).

[0154] The control sequence may also be a polyadenylation sequence, which is operably linked to the 3' end of the polynucleotide and, when transcribed, is recognized by a host cell as a signal for adding polyadenosine residues to the transcribed mRNA. Any polyadenylation sequence that functions in the host cell may be used.

[0155] Preferred polyadenylation sequences for filamentous fungal host cells are obtained from the genes for Bacillus nidulans anthranilate synthase, Bacillus niger glucoamylase, Bacillus niger alpha-glucosidase, Bacillus sibirica TAKA amylase, and Fusarium oxysporum trypsin-like protease.

[0156] Useful polyadenylation sequences for yeast host cells are described by Guo and Sherman, 1995, Mol. Cellular Biol. 15:5983-5990.

[0157] The control sequence may also be a signal peptide coding region that encodes a signal peptide linked to the N-terminus of a polypeptide, directing the polypeptide into the secretory pathway of a cell. The 5' end of the coding sequence of a polynucleotide may inherently contain a signal peptide coding sequence that is naturally linked in translation reading frame with the segment of the coding sequence encoding the polypeptide. Alternatively, the 5' end of the coding sequence may contain a signal peptide coding sequence that is foreign to the coding sequence. A foreign signal peptide coding sequence may be required if the coding sequence does not naturally contain a signal peptide coding sequence. Alternatively, the native signal peptide coding sequence may simply be replaced with a foreign signal peptide coding sequence to enhance secretion of the polypeptide. However, any signal peptide coding sequence that directs an expressed polypeptide into the secretory pathway of a host cell may be used.

[0158] Signal peptide coding sequences useful in bacterial host cells include those obtained from the genes encoding Bacillus NCIB 11837 maltogenic amylase, Bacillus licheniformis subtilisin, Bacillus licheniformis beta-lactamase, Bacillus stearothermophilus alpha-amylase, Bacillus stearothermophilus neutral protease (nprT, nprS, nprM), and Bacillus subtilis prsA. Additional signal peptides are described by Simonen and Palva, 1993, Microbiological Reviews 57:109-137.

[0159] Signal peptide coding sequences effective in filamentous fungal host cells are those obtained from the genes for Aspergillus niger neutral amylase, Aspergillus niger glucoamylase, Aspergillus oryzae TAKA amylase, Humicola insolens cellulase, Humicola insolens endoglucanase V, Humicola lanuginosa lipase, and Rhizomucor miehei aspartic proteinase.

[0160] Useful signal peptides for yeast host cells are obtained from the genes for Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiae invertase. Other useful signal peptide coding sequences are described by Romanos et al., 1992, supra.

[0161] The control sequence may also be a propeptide coding sequence encoding a propeptide located at the N-terminus of a polypeptide. The resulting polypeptide is known as a proenzyme or propolypeptide (or sometimes a zymogen). The polypeptide is generally inactive and can be converted to an active polypeptide by catalytic or autocatalytic cleavage of the propeptide from the propolypeptide. Propeptide coding sequences can be obtained from the genes for Bacillus subtilis alkaline protease (aprE), Bacillus subtilis neutral protease (nprT), Myceliophysora thermophila laccase (WO 95 / 33836), Rhizomucor miehei aspartic proteinase, and Saccharomyces cerevisiae alpha-factor.

[0162] When both a signal peptide and a propeptide sequence are present, the propeptide sequence is located adjacent to the N-terminus of the polypeptide and the signal peptide sequence is located adjacent to the N-terminus of the propeptide sequence.

[0163] It may also be desirable to add regulatory sequences that regulate polypeptide expression relative to the growth of the host cell. Examples of regulatory sequences are those that turn gene expression on or off in response to chemical or physical stimuli, including the presence of a regulatory compound. Regulatory sequences in prokaryotic systems include the lac, tac, and trp operator systems. In yeast, the ADH2 system or GAL1 system may be used. In filamentous fungi, the Aspergillus niger glucoamylase promoter, the Aspergillus oryzae TAKA α-amylase promoter, the Aspergillus oryzae glucoamylase promoter, the Trichoderma reesei cellobiohydrolase I promoter, and the Trichoderma reesei cellobiohydrolase II promoter may be used. Other examples of regulatory sequences are those that allow gene amplification. In eukaryotic systems, these regulatory sequences include the dihydrofolate reductase gene, which amplifies in the presence of methotrexate, and the metallothionein gene, which amplifies with heavy metals. In these cases, the polynucleotide encoding the polypeptide is operably linked to the regulatory sequence.

[0164] Expression vector The present application also discloses recombinant expression vectors containing polynucleotides encoding the DNase variants of the present invention, promoters, and transcriptional and translational stop signals. Various nucleotides and control sequences may be joined together to generate recombinant expression vectors, which may contain one or more convenient restriction enzyme sites to allow for insertion or substitution of a polynucleotide encoding a polypeptide at such sites. Alternatively, polynucleotides can be expressed by inserting the polynucleotide or a nucleic acid construct containing the polynucleotide into a vector suitable for expression. In creating an expression vector, a coding sequence is positioned within the vector such that the coding sequence is operably linked to suitable control sequences for expression. In a further embodiment, the codons of the polynucleotide sequence are modified by nucleotide substitution to correspond to the codon usage of the host organism in which the polypeptide of the present invention is intended to be produced. The recombinant expression vector may be any vector (e.g., a plasmid or virus) that can be conveniently subjected to recombinant DNA procedures and capable of expressing a polynucleotide. The choice of vector typically depends on the compatibility of the vector with the host cell into which it will be introduced. The vector may be a linear or closed circular plasmid.

[0165] The vector may be an autonomously replicating vector, i.e., a vector that exists as an extrachromosomal entity whose replication is independent of chromosomal replication, such as a plasmid, extrachromosomal element, minichromosome, or artificial chromosome. The vector may include any means for ensuring autonomous replication. Alternatively, the vector may be a vector that, when introduced into a host cell, is integrated into the genome and replicated together with the chromosome into which it has been integrated. Furthermore, a single vector or plasmid, or two or more vectors or plasmids, may be used that together contain the entire DNA or transposon to be introduced into the genome of the host cell.

[0166] Vectors preferably contain one or more selectable markers which permit easy selection of cells that have been transformed, transfected, transduced, etc. A selectable marker is a gene the product of which provides for biocide or viral resistance, resistance to heavy metals, prototrophy to auxotrophs, etc.

[0167] Examples of bacterial selectable markers are the dal genes of Bacillus licheniformis or Bacillus subtilis, or markers that confer antibiotic resistance such as ampicillin, chloramphenicol, kanamycin, neomycin, spectinomycin, or tetracycline resistance. Suitable markers for yeast host cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2, MET3, TRP1, and URA3. Selectable markers for use in filamentous fungal host cells include, but are not limited to, adeA (phosphoribosylaminoimidazole-succinocarboxamide synthase), adeB (phosphoribosylaminoimidazole synthase), amdS (acetamidase), argB (ornithine carbamoyltransferase), bar (phosphinolothrixin acetyltransferase), hph (hygromycin phosphotransferase), niaD (nitrate reductase), pyrG (orotidine-5'-phosphate decarboxylase), sC (sulfate adenyltransferase), and trpC (anthranilate synthase), and their equivalents. Preferred for use in Aspergillus cells are the amdS and pyrG genes of Aspergillus nidulans or Aspergillus oryzae, and the bar gene of Streptomyces hygroscopicus. Preferred for use in Trichoderma cells are the adeA, adeB, amdS, hph, and pyrG genes.

[0168] The selectable marker may be a double selectable marker system as described in WO 2010 / 039889. In one aspect, the double selectable marker is the hph-tk double selectable marker system.

[0169] The vector preferably contains elements that allow the vector to integrate into the genome of a host cell or to replicate autonomously within the cell independent of the genome. For integration into the genome of a host cell, the vector may rely on a polynucleotide sequence encoding a polypeptide or any other element of the vector for integration into the genome by homologous or non-homologous recombination. Alternatively, the vector may contain additional polynucleotides to direct integration into the genome of the host cell at a precise location in a chromosome by homologous recombination. To increase the likelihood of integration at a precise location, the integration element must 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, with high sequence identity to the corresponding target sequence to increase the likelihood of homologous recombination. The integration element may be any sequence homologous to the target sequence in the genome of the host cell. Furthermore, the integration element may be a non-coding or coding polynucleotide. Alternatively, the vector may be integrated into the genome of the host cell by non-homologous recombination.

[0170] For autonomous replication, the vector may further comprise an origin of replication that enables the vector to replicate autonomously in the intended host cell. The origin of replication may be any plasmid replicator that mediates autonomous replication that functions within the cell. The term "origin of replication" or "plasmid replicator" refers to a polynucleotide that enables a plasmid or vector to replicate in vivo.

[0171] Examples of bacterial origins of replication are the replication origins of the plasmids pBR322, pUC19, pACYC177, and pACYC184, which allow replication in E. coli, and pUB110, pE194, pTA1060, and pAMβ1, which allow replication in Bacillus.

[0172] Examples of origins of replication for use in a yeast host cell are the 2 micron origin of replication, ARS1, ARS4, the combination of ARS1 and CEN3, and the combination of ARS4 and CEN6.

[0173] Examples of replication origins useful 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). Isolation of the AMA1 gene and construction of a plasmid or vector containing the gene can be carried out according to the methods disclosed in WO 00 / 24883.

[0174] More than one copy of a polynucleotide of the invention can also be inserted into a host cell to increase production of the polypeptide. Increased copy number of the polynucleotide can be obtained by integrating at least one additional copy of the sequence into the genome of the host cell, or by including an amplifiable selectable marker gene with the polynucleotide, such that cells containing amplified copies of the selectable marker gene, and thus additional copies of the polynucleotide, can be selected by culturing the cells in the presence of an appropriate selectable agent.

[0175] The procedures used to ligate the above elements to construct the recombinant expression vectors of the present invention are well known to those of skill in the art (see, eg, Sambrook et al., 1989, supra).

[0176] host cell The present specification discloses recombinant host cells comprising a polynucleotide of the present invention operably linked to one or more control sequences that direct the production of a polypeptide of the present invention. A construct or vector containing the polynucleotide is introduced into a host cell so that the construct or vector is maintained as a chromosomal integrant or as a self-replicating extrachromosomal vector, as described above. The term "host cell" encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication. The choice of host cell will largely depend on the gene encoding the polypeptide and its origin.

[0177] The host cell may be any cell useful in the recombinant production of the polypeptides of the invention, eg, prokaryotic or eukaryotic.

[0178] Prokaryotic host cells can be any Gram-positive or Gram-negative bacteria. Gram-positive bacteria include, but are not limited to, Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus, Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus, and Streptomyces. Gram-negative bacteria include, but are not limited to, Campylobacter, Escherichia coli, Flavobacterium, Fusobacterium, Helicobacter, Iriobacter, Neisseria, Pseudomonas, Salmonella, and Ureaplasma.

[0180] Alternatively, the bacterial host cell may be any Streptococcus cell, including, but not limited to, Streptococcus equisimilis, Streptococcus pyogenes, Streptococcus uberis, and Streptococcus equi subsp. Zooepidemicus cells.

[0181] Alternatively, the bacterial host cell may be any Streptomyces cell, including, but not limited to, cells of Streptomyces achromogenes, Streptomyces avermitilis, Streptomyces coelicolor, Streptomyces griseus, and Streptomyces lividans.

[0182] Introduction of DNA into Bacillus cells can be carried out by protoplast transformation (see, e.g., Chang and Cohen, 1979, Mol. Gen. Genet. 168:111-115), competent cell transformation (see, e.g., Young and Spizizen, 1961, J. Bacteriol. 81:823-829, or Dubnau and Davidoff-Abelson, 1971, J. Mol. Biol. 56:209-221), electroporation (see, e.g., Shigekawa and Dower, 1988, Biotechniques 6:742-751), or conjugation (see, e.g., Koehler and Thorne, 1987, J. Bacteriol. 169:5271-5278). Introduction of DNA into E. coli cells can be carried out by protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol. 166:557-580) or electroporation (see, e.g., Dower et al., 1988, Nucleic Acids Res. 16:6127-6145). Introduction of DNA into Streptomyces cells can be carried out by protoplast transformation, electroporation (see, e.g., Gong et al., 2004, Folia Microbiol. (Praha) 49:399-405), conjugation (see, e.g., Mazodier et al., 1989, J. Bacteriol. 171:3583-3585), or transduction (see, e.g., Burke et al., 2001, Proc. Natl. Acad. Sci. USA 98:6289-6294). Introduction of DNA into Pseudomonas cells can be carried out by electroporation (see, e.g., Choi et al., 2006, J. Microbiol. Methods 64:391-397) or conjugation (see, e.g., Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71:51-57).Introduction of DNA into Streptococcus cells can be carried out by natural competent transformation (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), electroportation (see, e.g., Buckley et al., 1999, Appl. Environ. Microbiol. 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.

[0183] The host cell may also be a eukaryotic cell, such as a mammalian, insect, plant, or fungal cell.

[0184] The host cell may be a fungal cell. "Fungi," as used herein, includes the Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota, as well as the Oomycota and all vegetative spore-forming fungi (as defined by Hawksworth et al., in Ainsworth and Bisby's Dictionary of The Fungi, 8th ed., 1995, CAB International, University Press, Cambridge, UK).

[0185] The fungal host cell may be a yeast cell. "Yeast," as used herein, includes ascospore-forming yeasts (Endomycetales), basidiospore-forming yeasts, and yeasts belonging to the Fungi Imperfecti (Blastomycetes). Because the classification of yeasts may change in the future, for purposes of the present invention, yeasts shall be defined as described in Biology and Activities of Yeast (Skinner, Passmore, and Davenport, editors, Soc. App. Bacteriol. Symposium Series No. 9, 1980).

[0186] Yeast host cells include cells of the genera Candida, Hansenula, Kluyveromyces, Pichia, Saccharomyces, Schizosaccharomyces, or Yarrowia, such as Kluyveromyces lactis, Saccharomyces carlsbergensis, Saccharomyces cerevisiae, Saccharomyces diastaticus, Saccharomyces douglasii, Saccharomyces kluyveri, Saccharomyces norbensis, Saccharomyces oviformis, or Yarrowia lipolytica. lipolytica cells.

[0187] The fungal host cell may be a filamentous fungal cell. "Filamentous fungi" includes all filamentous forms of the subdivision Euglena and Oomycota (as defined by Hawksworth et al., 1995, supra). Filamentous fungi are generally characterized by a mycelial wall composed of chitin, cellulose, glucan, chitosan, mannan, and other complex polysaccharides. Vegetative growth is by hyphal elongation, and carbon catabolism is obligately aerobic. In contrast, vegetative growth by yeasts such as Saccharomyces cerevisiae is by budding of a unicellular thallus, and carbon catabolism can be fermentative.

[0188] The filamentous fungal host cell can be a cell of the genus Acremonium, Bacillus, Aureobasidium, Bialecandera, Seripoliopsis, Chrysosporium, Coprinus, Coriolus, Cryptococcus, Filibasidium, Fusarium, Humicola, Magnaporthe, Mucor, Myceliophysora, Neocallimastyx, Neurospora, Paecilomyces, Penicillium, Phanerochaete, Phlebia, Piromyces, Pleurotus, Schizophyllium, Talaromyces, Cellmoascus, Chelabia, Tolypocladium, Trametes, or Trichoderma.

[0190] Fungal cells can be transformed by a process involving protoplast formation, transformation of the protoplasts, and regeneration of the cell wall in a process known per se. Suitable procedures for transformation of Aspergillus and Trichoderma host cells are described in EP 238023, Yelton et al., 1984, 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 Malardier et al., 1989, Gene 78:147-156, and WO 96 / 00787. Yeast can be transformed using the procedures described by Becker and Guarente, in Abelson, J. N. and Simon, M. I., editors, Guide to Yeast Genetics and Molecular Biology, Methods in Enzymology, Volume 194, pp 182-187, Academic Press, Inc., New York; Ito et al., 1983, J. Bacteriol. 153:163 and Hinnen et al., 1978, Proc. Natl. Acad. Sci. USA 75:1920.

[0267] The pH of the wash solution is typically in the range of about 5.5 to about 10, more typically in the range of 7 to 9, for example, in the range of about 7 to about 8.5 or about 7 to about 8.

[0268] The concentration of DNase variant and any additional enzymes in the wash solution is typically in the range of 0.00001 ppm to 10 ppm of enzyme protein, 0.00002 ppm to 10 ppm, 0.0001 ppm to 10 ppm, 0.0002 ppm to 10 ppm, 0.001 ppm to 10 ppm, 0.002 ppm to 10 ppm, 0.01 ppm to 10 ppm, 0.02 ppm to 10 ppm, 0.1 ppm to 10 ppm, 0.2 ppm to 10 ppm, or 0.5 ppm to 5 ppm. [Example]

[0269] Materials and Methods Assay I: Determination of DNase activity DNase activity can be determined using the DNaseAlert™ kit (IDT, Intergrated DNA Technologies, Belgium) according to the supplier's manual. For an example of this assay, see Example 2 below.

[0270] Assay II: Storage stability assay for purified DNase variants The storage stability of purified DNase variants in detergent compositions, expressed as half-life improvement factors relative to a reference DNase, can be determined, for example, as described in Example 3 below.

[0271] Example 1: Construction and screening of variants Site-directed variants of the DNase of SEQ ID NO: 1 containing specific substitutions were constructed. Mutants were generated by conventional DNA fragment cloning (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor, 1989) using PCR with appropriately designed mutagenic oligonucleotides to introduce the desired mutations into the resulting sequence.

[0272] Mutagenic oligos corresponding to the DNA sequences flanking the desired mutation sites, separated by DNA base pairs defining the insertion / deletion / substitution, were designed and purchased from oligo vendors such as Life Technologies. To test DNase variants, DNA containing the variants was integrated into competent Bacillus subtilis strains by homologous recombination. Transformants were grown for 1 hour in antibiotic-free TB-Gly growth medium and then overnight in TB-Gly medium containing 3 μg / ml chloramphenicol. After adding glycerol to 25% v / v, they were stored at -80°C. Replicates were grown for 3–4 days for DNase production in broth supplemented with chloramphenicol and trace elements: 50 μM FeCl3, 20 μM CaCl2, 10 μM MnCl2, 10 μM ZnSO4, and 2 μM CuCl2.

[0273] Example 2: Stability screening of DNase variants in supernatant After growth, each supernatant sample was split into two identical samples by transferring 20 μl of supernatant to two 96-well standard microtiter plates, each containing 170 μl of TidePods® 3-in-1 detergent supplemented with 1% (v / v) liquid laundry protease, Progress® Uno 101 L (Novozymes A / S), and 0.3% (w / v) sodium bisulfite. After shaking at 7500 rpm for 20 minutes on a microtiter plate shaker, one microtiter plate was incubated at 10°C for 3 days (reference condition), and the other microtiter plate was incubated at 50°C in an incubator for 3 days (stress condition). After 3 days, both sample sets (reference and stress conditions) were diluted 20-fold with dilution buffer (50 mM Tris, HCl, 0.01% Tween® 20, pH 7.5) and then diluted with DNAseAlert™ substrate solution (Integrated DNA Technologies / Belgium, part number 11-04-02-04. Ten microliters of 20-fold diluted reference and stressed DNase samples were transferred to a new 384-well microtiter plate, and 40 μL of DNAseAlert™ assay solution was added (50 mM TrisHCl, pH 7.5, 5 mM MnCl2, 0.01% Tween® 20, 10 μM DNAseAlert™ substrate). Fluorescence (excitation 536 nm and emission 556 nm) was read every 90 seconds for a total of 30 minutes. From the rate curves, the slopes of the reference sample (activity under reference conditions) and the corresponding stressed sample (activity under stress conditions) were determined by linear regression. The residual activity (RA) of each DNase variant and the reference DNase (SEQ ID NO: 1) was calculated as slope(stressed sample) / slope(reference sample). RA was used to calculate half-life, and the half-life improvement factor was calculated as the stress time (min). *The half-life was calculated as ln(0.5) / ln(RA). The calculated half-lives for the variant and reference were used to calculate the half-life improvement factor as the ratio between the half-life of the variant and the half-life of the reference. The half-life improvement factor relative to the reference is, by definition, 1.0, and variants with a half-life improvement factor greater than the reference have improved stability under the test conditions.

[0274] Single mutation variants showing improved stability in the supernatant screen were used for the construction and screening of combinatorial variants containing two or more individual mutations.

[0275] Transformations of these improved single-mutation hits were streaked to single colonies, sequenced, and grown overnight in TB-Gly broth containing 3 μg / ml chloramphenicol. After growth in shake flasks in 100 ml of PS-1 growth medium containing trace elements at 30°C for 4 days, the enzyme variants were purified and their stability was tested in two different liquid detergents as described below.

[0276] Single mutations that confer improved stability were combined in combinatorial variants containing two or more mutations compared to SEQ ID NO: 1. These were streaked to single colonies immediately after transformation, then screened and sequenced as described above. The improved combinatorial variants were then grown, purified, and tested for storage stability in two different liquid detergents as described below.

[0277] For variants subsequently tested in purified form, stability data are presented in Tables 2 and 3 of Example 3. Table 1A presents stability data for several additional variants tested as supernatants in concentrated liquid detergent (Tide Pods® 3-in-1) stored at 55°C.

[0278] Other DNase variants were tested in a similar manner as above, but incubated in 10% Ariel Essential detergent with 1% protease (SEQ ID NO: 28) at a temperature of 58° C. The test results are shown in Table 1B below.

[0279] [Table 1]

[0280] [Table 2]

[0281] Example 3: Storage stability assay of purified DNase variants After purification (a two-step procedure using a PPA HyperCel column and an SP-Sepharose® FF column), the purified DNase variants were diluted to 0.2 and 0.1 mg / ml with 0.01% Triton X-100, and concentrations were calculated using absorbance at 280 nm. For each enzyme variant, two wells at high concentration (0.2 mg / ml) and two wells at low concentration (0.1 mg / ml) were tested. 15 μl of diluted DNase sample was mixed in a well of a microtiter plate ("detergent plate," Nunc U 96 PP 0.5 ml) with 285 μl of concentrated detergent (1) Tide Pod® 3-in-1, green compartment supplemented with 0.3% sodium bisulfite and 1% liquid laundry protease Progress® Uno 101 L (Novozymes A / S) or Tide Original HE Heavy-Duty Liquid supplemented with 1% Progress® Uno 101 L using a magnetic bar. After mixing, the detergent plate was incubated at 50°C in a Biosan PST-100HL thermomixer.

[0282] After various incubation times (e.g., 0, 2, 24, and 72 hours), residual DNase activity was measured. Five μl from the detergent plate was mixed with 195 μl of DNA substrate solution (3.3 mg DNA (Sigma D1626) in 50 mM Tris pH 7, 5 mM MgCl2, 5 mM CaCl2, 1.3 mM EDTA). Viscosity was measured once per minute for 30 minutes using pressure sensing during aspiration on a Hamilton Microlab STAR. Activity was calculated from the measured viscosity reduction.

[0283] The decrease in activity during incubation with detergent is assumed to be exponential. The half-life (T) was found from linear regression of Log(activity) versus incubation time, and the half-life improvement factor (HIF) was calculated as the half-life of the DNase variant relative to the half-life of the reference DNase.

[0284] The half-life improvement factors for the DNase variants are shown below in Tables 2 and 3. Table 2 shows the results for variants tested in concentrated liquid detergent Tide Pods® 3-in-1, and Table 3 shows the results for variants tested in heavy-duty liquid detergent Tide Original HE.
