DETERGENT COMPOSITION COMPRISING SUBTILASE VARIANTS

REFERENCE TO A SEQUENCE LISTING

This application contains a Sequence Listing in computer readable form, which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a detergent composition comprising subtilase variants, such as laundry detergent compositions and dish wash compositions, including automatic dish wash compositions. The present disclosure also relates to the use of said detergent compositions in a cleaning process such as laundry or hard surface cleaning. The present disclosure further relates to a method for removing a stain from a surface, which comprises contacting the surface with the detergent composition.

BACKGROUND

In the detergent industry, enzymes have for many decades been implemented in washing formulations. Enzymes used in such formulations comprise amylases, cellulases, lipases, mannosidases, and proteases, as well as other enzymes or mixtures thereof. Commercially the most important enzymes are proteases.

An increasing number of commercially used proteases are protein engineered variants of naturally occurring wild type proteases Everlase®, Relase®, Ovozyme®, Polarzyme®, Liquanase®, Liquanase Ultra® and Kannase® (Novozymes A/S), Purafast®, Purafect OXP®, FN3®, FN4® and Excellase® (Genencor International, Inc.). Further, a number of variants are described in the art, such as in WO1996/034946, WO 2004/041979 and WO2000/037599 (Novozymes A/S) which describes subtilase variants exhibiting alterations relative to the parent subtilase in, e.g., wash performance, thermal stability, storage stability or catalytic activity. The variants are suitable for use in, e.g., cleaning or detergent compositions.

A number of subtilase variants have been described many of which have provided improved activity, stability, and solubility in different detergents.

However, various factors make further improvement of the proteases advantageous. Washing conditions such as temperature and pH change over time and many stains are still difficult to completely remove under conventional washing conditions. Despite intensive research in protease development there remains a need for proteases that have improved wash performance in detergent compositions compared to the parent subtilase.

The terms “detergent composition” and “detergent formulation” are used in reference to mixtures which are intended for use in a wash medium for the cleaning of soiled objects. In some embodiments, the term is used in reference to laundering fabrics and/or garments (e.g., “laundry detergents”). In alternative embodiments, the term refers to other detergents, such as those used to clean dishes, cutlery, etc. (e.g., “dishwashing detergents”). It is not intended that the present disclosure be limited to any particular detergent formulation or composition. The term “detergent composition” is not intended to be limited to compositions that contain surfactants. The term encompasses detergents that may contain, e.g., surfactants, builders, chelators or chelating agents, bleach system or bleach components, polymers, fabric conditioners, foam boosters, suds suppressors, dyes, perfume, tannish inhibitors, optical brighteners, bactericides, fungicides, soil suspending agents, anticorrosion agents, enzyme inhibitors or stabilizers, enzyme activators, transferase(s), hydrolytic enzymes, oxido reductases, bluing agents and fluorescent dyes, antioxidants, and solubilizers.

In addition to containing a subtilase variant as disclosed herein, the detergent formulation of the present disclosure may contain one or more additional enzymes (such as amylases, catalases, cellulases (e.g., endoglucanases), cutinases, haloperoxygenases, lipases, mannanases, pectinases, pectin lyases, peroxidases, proteases, xanthanases, and xyloglucanases, or any mixture thereof), and/or components such as surfactants, builders, chelators or chelating agents, bleach system or bleach components, polymers, fabric conditioners, foam boosters, suds suppressors, dyes, perfume, tannish inhibitors, optical brighteners, bactericides, fungicides, soil suspending agents, anti-corrosion agents, enzyme inhibitors or stabilizers, enzyme activators, transferase(s), hydrolytic enzymes, oxidoreductases, bluing agents and fluorescent dyes, antioxidants, and solubilizers.

The term “dish wash” refers to all forms of washing dishes, e.g., by hand or automatic dish wash. Washing dishes includes, but is not limited to, the cleaning of all forms of crockery such as plates, cups, glasses, bowls, all forms of cutlery such as spoons, knives, forks and serving utensils as well as ceramics, plastics such as melamine, metals, china, glass and acrylics.

The term “dish washing composition” refers to all forms of compositions for cleaning hard surfaces. The present disclosure is not restricted to any particular type of dish wash composition or any particular detergent.

The term “hard surface cleaning” is defined herein as cleaning of hard surfaces wherein hard surfaces may include floors, tables, walls, roofs etc. as well as surfaces of hard objects such as cars (car wash) and dishes (dish wash). Dishwashing includes but are not limited to cleaning of plates, cups, glasses, bowls, and cutlery such as spoons, knives, forks, serving utensils, ceramics, plastics such as melamine, metals, china, glass and acrylics.

The term “improved property” means a characteristic associated with a subtilase variant that is improved compared to the parent subtilase. Such improved properties include, but are not limited to, wash performance, protease activity, thermal activity profile, thermostability, pH activity profile, pH stability, substrate/cofactor specificity, improved surface properties, substrate specificity, product specificity, increased stability, improved stability under storage conditions, and chemical stability.

The term “stability” includes storage stability and stability during use, e.g., during a wash process and reflects the stability of the subtilase variant as a function of time, e.g., how much activity is retained when the subtilase variant is kept in solution in particular in a detergent solution. The stability is influenced by many factors, e.g., pH, temperature, detergent composition, e.g., amount of builder, surfactants etc.

The term “improved stability” or “increased stability” is defined herein as a variant subtilase displaying an increased stability in solution, relative to the stability of the parent subtilase. The terms “improved stability” and “increased stability” includes “improved chemical stability”, “detergent stability” or “improved detergent stability.

The term “improved chemical stability” is defined herein as a variant subtilase displaying retention of enzymatic activity after a period of incubation in the presence of a chemical or chemicals, either naturally occurring or synthetic, which reduces the enzymatic activity of the parent enzyme. Improved chemical stability may also result in variants being more able to catalyze a reaction in the presence of such chemicals. The improved chemical stability is an improved stability of the variant in the detergent composition according to present disclosure, in particular in a liquid detergent. The term “detergent stability” or “improved detergent stability is in particular an improved stability of the protease activity when a subtilase variant is mixed into a liquid detergent formulation, and then stored at a temperature between about 15 and about 50° C., e.g., 20° C., 30° C. or 40° C.

The term “improved thermal activity” means a variant displaying an altered temperature-dependent activity profile at a specific temperature relative to the temperature-dependent activity profile of the parent. The thermal activity value provides a measure of the variant's efficiency in enhancing catalysis of a hydrolysis reaction over a range of temperatures. A more thermo-active variant will lead to an increase in enhancing the rate of hydrolysis of a substrate by an enzyme composition thereby decreasing the time required and/or decreasing the enzyme concentration required for activity. Alternatively, a variant with a reduced thermal activity will enhance an enzymatic reaction at a temperature lower than the temperature optimum of the parent defined by the temperature-dependent activity profile of the parent.

The term “improved wash performance” is defined herein as a detergent composition comprising a subtilase variant as contemplated herein displaying an improved wash performance relative to the wash performance of the detergent composition comprising the corresponding parent protease, e.g., by increased stain removal. The term “wash performance” includes wash performance in laundry but also, e.g., in dish wash. The wash performance may be quantified as described under the definition of “wash performance” herein.

The term “isolated” means a substance in a form or environment which does not occur in nature. Non-limiting examples of isolated substances include (1) any non-naturally occurring substance, (2) any substance including, but not limited to, any enzyme, variant, nucleic acid, protein, peptide or cofactor, that is at least partially removed from one or more or all of the naturally occurring constituents with which it is associated in nature; (3) any substance modified by the hand of man relative to that substance found in nature; or (4) any substance modified by increasing the amount of the substance relative to other components with which it is naturally associated (e.g., multiple copies of a gene encoding the substance; use of a stronger promoter than the promoter naturally associated with the gene encoding the substance). An isolated substance may be present in a fermentation broth sample.

The term “laundering” relates to both household laundering and industrial laundering and means a process of treating textiles and/or fabrics with a solution containing a detergent composition of the present disclosure. The laundering process can for example be carried out using, e.g., a household or an industrial washing machine or can be carried out by hand.

The term “mature polypeptide” means a polypeptide in its final form following translation and any post-translational modifications, such as N-terminal processing, C-terminal truncation, glycosylation, phosphorylation, autocatalytic activation etc. In one aspect, the mature polypeptide is amino acids 1 to 269 of SEQ ID NO: 1 and 1 to 275 of SEQ ID NO: 2. It is known in the art that a host cell may produce a mixture of two of more different mature polypeptides (i.e., with a different C-terminal and/or N-terminal amino acid) expressed by the same polynucleotide.

The term “mature polypeptide coding sequence” means a polynucleotide that encodes a mature polypeptide having protease activity.

The term “parent” means a protease to which an alteration is made to produce the enzyme variants comprised in the detergent composition of the present disclosure. It will be understood that in the present context the expression “having identical amino acid sequence” relates to 100% sequence identity. In a particular embodiment the parent is a protease with at least about 60% identity, such as at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 81%, at least about 82%, at least about 83%, at least about 84%, at least about 85%, at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or 100% identity to a polypeptide of SEQ ID NO: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11.

The term “protease” is defined herein as an enzyme that hydrolyzes peptide bonds. It includes any enzyme belonging to the EC 3.4 enzyme group (including each of the thirteen subclasses thereof). The EC number refers to Enzyme Nomenclature 1992 from NC-IUBMB, Academic Press, San Diego, Calif., including supplements 1-5 published in Eur. J. Biochem. 1223: 1-5 (1994); Eur. J. Biochem. 232: 1-6 (1995); Eur. J. Biochem. 237: 1-5 (1996); Eur. J. Biochem. 250: 1-6 (1997); and Eur. J. Biochem. 264: 610-650 (1999); respectively. The most widely used proteases in the detergent industry such as laundry and dish wash are the serine proteases or serine peptidases which is a subgroup of proteases exemplified by having a serine in the active site, which forms a covalent adduct with the substrate. Further the subtilases (and the serine proteases) are exemplified by having two active site amino acid residues apart from the serine, namely a histidine residue and an aspartic acid residue. Subtilase refer to a sub-group of serine protease according to Siezen et al., 1991, Protein Engng. 4: 719-737 and Siezen et al., 1997, Protein Science 6: 501-523. The subtilases may be divided into 6 sub-divisions, i.e., the Subtilisin family, the Thermitase family, the Proteinase K family, the Lantibiotic peptidase family, the Kexin family and the Pyrolysin family. The term “protease activity” means a proteolytic activity (EC 3.4). Proteases usably in detergents are mainly endopeptidases (EC 3.4.21). There are several protease activity types: The three main activity types are: trypsin-like where there is cleavage of amide substrates following Arg or Lys at P1, chymotrypsin-like where cleavage occurs following one of the hydrophobic amino acids at P1, and elastase-like with cleavage following an Ala at P1. For purposes of the present disclosure, protease activity is determined according to the Suc-AAPF-pNA activity assay, as described in the Materials and Methods section below. In one aspect, the subtilase variants of the present disclosure have at least about 20%, e.g., at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, or at least 100% of the enzyme activity of the mature polypeptide of the parent enzyme. In one particular aspect the subtilase variants of the present disclosure have at least about 20%, e.g., at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, or at least 100% of the enzyme activity of a polypeptide of SEQ ID NO: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11.

The term “protease activity” means a proteolytic activity (EC 3.4). Proteases of the present disclosure are endopeptidases (EC 3.4.21). There are several protease activity types: The three main activity types are: trypsin-like where there is cleavage of amide substrates following Arg or Lys at P1, chymotrypsin-like where cleavage occurs following one of the hydrophobic amino acids at P1, and elastase-like with cleavage following an Ala at P1. For purposes of the present disclosure, protease activity is determined according to the procedure described in “Materials and Methods” below. The subtilase variants of the present disclosure preferably have at least about 20%, e.g., at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, and at least 100% of the protease activity of a polypeptide of SEQ ID NO: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11.

The relatedness between two amino acid sequences or between two nucleotide sequences is described by the parameter “sequence identity”. For purposes of the present disclosure, the sequence identity between two amino acid sequences is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16: 276-277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled “longest identity” (obtained using the -nobrief option) is used as the percent identity and is calculated as follows: (Identical Residues×100)/(Length of Alignment−Total Number of Gaps in Alignment)

The term “substantially pure variant” means a preparation that contains at most 10%, at most about 8%, at most about 6%, at most about 5%, at most about 4%, at most about 3%, at most about 2%, at most about 1%, and at most about 0.5% by weight of other polypeptide material with which it is natively or recombinantly associated. Preferably, the variant is at least about 92% pure, e.g., at least about 94% pure, at least about 95% pure, at least about 96% pure, at least about 97% pure, at least about 98% pure, at least about 99%, at least about 99.5% pure, and 100% pure by weight of the total polypeptide material present in the preparation. The variants comprised in the detergent composition of the present disclosure are preferably in a substantially pure form. This can be accomplished, for example, by preparing the variant by well-known recombinant methods or by classical purification methods.

The term “textile” refers to woven fabrics, as well as staple fibers and filaments suitable for conversion to or use as yarns, woven, knit, and non-woven fabrics. The term encompasses yarns made from natural, as well as synthetic (e.g., manufactured) fibers. The term, “textile materials” is a general term for fibers, yarn intermediates, yarn, fabrics, and products made from fabrics (e.g., garments and other articles).

The term “non-fabric detergent compositions” include non-textile surface detergent compositions, including but not limited to compositions for hard surface cleaning, such as dishwashing detergent compositions, oral detergent compositions, denture detergent compositions, and personal cleansing compositions.

The term “effective amount of enzyme” refers to the quantity of enzyme necessary to achieve the enzymatic activity required in the specific application, e.g., in a defined detergent composition. Such effective amounts are readily ascertained by one of ordinary skill in the art and are based on many factors, such as the particular enzyme used, the cleaning application, the specific composition of the detergent composition, and whether a liquid or dry (e.g., granular, bar) composition is required, and the like. The term “effective amount” of a protease variant refers to the quantity of protease variant described hereinbefore that achieves a desired level of enzymatic activity, e.g., in a defined detergent composition.

The term “water hardness” or “degree of hardness” or “dH” or “° dH” as used herein refers to German degrees of hardness. One degree is defined as 10 milligrams of calcium oxide per litre of water.

The term “relevant washing conditions” is used herein to indicate the conditions, particularly washing temperature, time, washing mechanics, detergent concentration, type of detergent and water hardness, actually used in households in a detergent market segment.

The term “adjunct materials” means any liquid, solid or gaseous material selected for the particular type of detergent composition desired and the form of the product (e.g., liquid, granule, powder, bar, paste, spray, tablet, gel, or foam composition), which materials are also preferably compatible with the protease variant enzyme used in the composition. In some embodiments, granular compositions are in “compact” form, while in other embodiments, the liquid compositions are in a “concentrated” form.

The term “stain removing enzyme” as used herein, describes an enzyme that aids the removal of a stain or soil from a fabric or a hard surface. Stain removing enzymes act on specific substrates, e.g., protease on protein, amylase on starch, lipase and cutinase on lipids (fats and oils), pectinase on pectin and hemicellulases on hemicellulose. Stains are often depositions of complex mixtures of different components which either results in a local discolouration of the material by itself or which leaves a sticky surface on the object which may attract soils dissolved in the washing liquor thereby resulting in discolouration of the stained area. When an enzyme acts on its specific substrate present in a stain the enzyme degrades or partially degrades its substrate thereby aiding the removal of soils and stain components associated with the substrate during the washing process. For example, when a protease acts on a grass stain it degrades the protein components in the grass and allows the green/brown colour to be released during washing.

The term “reduced amount” means in this context that the amount of the component is smaller than the amount which would be used in a reference process under otherwise the same conditions. In a preferred embodiment the amount is reduced by, e.g., at least about 5%, such as at least about 10%, at least about 15%, at least about 20% or as otherwise herein described.

The term “low detergent concentration” system includes detergents where less than about 800 ppm of detergent components is present in the wash water. Asian, e.g., Japanese detergents are typically considered low detergent concentration systems.

The term “medium detergent concentration” system includes detergents wherein between about 800 ppm and about 2000 ppm of detergent components is present in the wash water. North American detergents are generally considered to be medium detergent concentration systems.

The term “high detergent concentration” system includes detergents wherein greater than about 2000 ppm of detergent components is present in the wash water. European detergents are generally considered to be high detergent concentration systems.

The term “variant” means a polypeptide having protease activity comprising an alteration, i.e., a substitution, insertion, and/or deletion, at three or more (e.g., several) positions. A substitution means replacement of the amino acid occupying a position with a different amino acid; a deletion means removal of the amino acid occupying a position; and an insertion means adding one or more (e.g., several) amino acids, e.g., 1, 2, 3, 4 or 5 amino acids adjacent to and immediately following the amino acid occupying a position. The term subtilase variant means a variant of a subtilase parent, i.e., a subtilase variant is a subtilase which comprises alterations i.e., a substitution, insertion, and/or deletion, at three or more (e.g., several) positions compared to the parent subtilase.

The term “wash performance” is used as an enzyme's ability to remove stains present on the object to be cleaned during, e.g., wash, such as laundry or hard surface cleaning.

The improvement in the wash performance may be quantified by calculating the so-called intensity value (Int) defined in the AMSA assay, as described in Example 3.

The term “wild-type subtilase” means a protease expressed by a naturally occurring organism, such as a bacterium, archaea, yeast, fungus, plant or animal found in nature. An example of a wild-type subtilase is subtilisin BPN′, i.e., amino acids 1 to 275 of SEQ ID NO: 2.

Conventions for Designation of Variants

For purposes of the present disclosure, subtilisin BPN′ (the sequence of amino acids 1-275 of SEQ ID NO: 2) is used to determine the corresponding amino acid residue in another protease. The amino acid sequence of another protease is aligned with the mature polypeptide disclosed in SEQ ID NO: 2, and based on the alignment, the amino acid position number corresponding to any amino acid residue in the polypeptide disclosed in SEQ ID NO: 2 is determined using the Needleman-Wunsch algorithm as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix.

Identification of the corresponding amino acid residue in another protease can be determined by an alignment of multiple polypeptide sequences using several computer programs including, but not limited to, MUSCLE (multiple sequence comparison by log-expectation; version 3.5 or later), MAFFT (version 6.857 or later), and EMBOSS EMMA employing ClustalW (1.83 or later), using their respective default parameters.

When the other enzyme has diverged from the mature polypeptide of SEQ ID NO: 2 such that traditional sequence-based comparison fails to detect their relationship, other pairwise sequence comparison algorithms can be used. Greater sensitivity in sequence-based searching can be attained using search programs that utilize probabilistic representations of polypeptide families (profiles) to search databases. For example, the PSI-BLAST program generates profiles through an iterative database search process and is capable of detecting remote homologs. Even greater sensitivity can be achieved if the family or superfamily for the polypeptide has one or more representatives in the protein structure databases. Programs such as GenTHREADER utilize information from a variety of sources (PSI-BLAST, secondary structure prediction, structural alignment profiles, and solvation potentials) as input to a neural network that predicts the structural fold for a query sequence. Similarly, the method of Gough et al., 2000, J. Mol. Biol. 313: 903-919, can be used to align a sequence of unknown structure with the superfamily models present in the SCOP database. These alignments can in turn be used to generate homology models for the polypeptide, and such models can be assessed for accuracy using a variety of tools developed for that purpose.

For proteins of known structure, several tools and resources are available for retrieving and generating structural alignments. For example the SCOP superfamilies of proteins have been structurally aligned, and those alignments are accessible and downloadable.

In one aspect, the total number of alterations in the parent subtilase is between 3 and 30, preferably between 3 and 20, more preferably between 3 and 15, even more preferably between 3 and 10, most preferably between 3 and 8 alterations. In another aspect, total number of alterations in the parent subtilase is 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 or 30 alterations.

The subtilase variants comprised in the detergent composition of the present disclosure may further comprise one or more additional alterations. The amino acid changes may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-30 amino acids; small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.

Examples of conservative substitutions are within the groups 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 small amino acids (glycine, alanine, serine, threonine and methionine). Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, 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.

Alternatively, the amino acid changes are of such a nature that the physico-chemical properties of the polypeptides are altered. For example, amino acid changes may improve the thermal stability of the polypeptide, alter the substrate specificity, change the pH optimum, and the like.

Essential amino acids in a polypeptide can be identified according to 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 resultant mutant molecules are tested for protease activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids.

The subtilase variants may consist of from about 150 to about 350, e.g., from about 175 to about 330, from about 200 to about 310, from about 220 to about 300, from about 240 to about 290, from about 260 to about 280 or 269, 270, 271, 272, 273, 274 or 275 amino acids.

Parent Protease

The parent or the precursor protease may be any subtilase or even more preferred any subtilisin as defined below.

Enzymes cleaving the amide linkages in protein substrates are classified as proteases, or (interchangeably) peptidases.

Serine Proteases

A serine protease is an enzyme, which catalyzes the hydrolysis of peptide bonds, and in which there is an essential serine residue at the active site.

The bacterial serine proteases have molecular weights in the from about 20,000 to about 45,000 Dalton range. They are inhibited by diisopropylfluorophosphate. They hydrolyze simple terminal esters and are similar in activity to eukaryotic chymotrypsin, also a serine protease. A more narrow term, alkaline protease, covering a sub-group, reflects the high pH optimum of some of the serine proteases, from pH from about 9.0 to about 11.0.

Subtilases

A sub-group of the serine proteases tentatively designated subtilases has been proposed by Siezen et al., 1991, Protein Eng. 4:719-737 and Siezen et al., 1997, Protein Science 6:501-523. They are defined by homology analysis of more than 170 amino acid sequences of serine proteases previously referred to as subtilisin-like proteases. A subtilisin was previously often defined as a serine protease produced by Gram-positive bacteria or fungi, and according to Siezen et al. now is a subgroup of subtilases. A wide variety of subtilases have been identified, and the amino acid sequence of a number of subtilases has been determined. For a more detailed description of such subtilases and their amino acid sequences reference is made to Siezen et al. (1997).

Subtilisins

A subgroup of subtilases is subtilisins which are serine proteases from the family S8, in particular from the subfamily S8A, as defined by the MEROPS database (merops.sanger.ac.uk/cgi-bin/famsum?family=S8).

Subtilisin BPN′ and subtilisin 309 have the MEROPS numbers 508.034 and S08.003, respectively.

Parent Subtilase

The term “parent subtilase” describes a subtilase defined according to Siezen et al., 1997, Protein Science 6: 501-523. For further details see description of “Subtilases” above. A parent subtilase may also be a subtilase isolated from a natural source, wherein subsequent modifications (such as replacement(s) of the amino acid side chain(s), substitution(s), deletion(s) and/or insertion(s)) have been made while retaining the characteristic of a subtilase. Furthermore, a parent subtilase may be a subtilase which has been prepared by the DNA shuffling technique.

Alternatively, the term “parent subtilase” may be termed “precursor subtilase” and is used to describe the starting protease into which mutations are made to obtain the variant of the present disclosure. The parent subtilase is preferably of the subtilisin subgroups.

One subgroup of the subtilases, I-S1 or “true” subtilisins, include the “classical” subtilisins, such as subtilisin 168 (BSS168), subtilisin BPN′, subtilisin Carlsberg (ALCALASE®, Novozymes A/S), and subtilisin DY (BSSDY). BPN′ is subtilisin BPN′ from B. amyloliquefaciens, Subtilisin BPN′ has the amino acid sequence of SEQ ID NO: 2. A further subgroup of the subtilases, I-S2 or high alkaline subtilisins, is recognized by Siezen et al. (supra). Sub-group I-S2 proteases are described as highly alkaline subtilisins and include enzymes such as subtilisin PB92 (BAALKP) (MAXACAL®, Genencor International Inc.), subtilisin 147 (BLS147) (ESPERASE®, Novozymes A/S), alkaline elastase YaB (BSEYAB) and subtilisin 309 (SAVINASE®, Novozymes A/S) having the amino acid sequence SEQ ID NO: 1.

For reference, Table 1 below gives a list of some acronyms for various subtilases mentioned herein. For further acronyms, see Siezen et al. (1991 and 1997).

(iii) the variant has at least about 60%, e.g., at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, at least about 96%, at least about 97%, at least about 98% but less than 100% sequence identity to the polypeptide of SEQ ID NO: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11; and

(B) recovering the variant

(C) adding the variant to a detergent composition.

The variants can be prepared using any mutagenesis procedure known in the art, such as site-directed mutagenesis, synthetic gene construction, semi-synthetic gene construction, random mutagenesis, shuffling, etc.

Site-directed mutagenesis is a technique in which one or more (e.g., several) mutations are introduced at one or more defined sites in a polynucleotide encoding the parent.

Site-directed mutagenesis can be accomplished in vitro by PCR involving the use of oligonucleotide primers containing the desired mutation. Site-directed mutagenesis can also be performed in vitro by cassette mutagenesis involving the cleavage by a restriction enzyme at a site in the plasmid comprising a polynucleotide encoding the parent and subsequent ligation of an oligonucleotide containing the mutation in the polynucleotide. Usually the restriction enzyme that digests the plasmid and the oligonucleotide is the same, permitting sticky ends of the plasmid and the insert to ligate to one another.

Site-directed mutagenesis can also be accomplished in vivo by methods known in the art.

Any site-directed mutagenesis procedure can be used in the present disclosure. There are many commercial kits available that can be used to prepare variants.

Synthetic gene construction entails in vitro synthesis of a designed polynucleotide molecule to encode a polypeptide of interest. Gene synthesis can be performed utilizing a number of techniques, such as the multiplex microchip-based technology and similar technologies wherein oligonucleotides are synthesized and assembled upon photo-programmable microfluidic chips.

Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by WO 95/17413 or WO 95/22625. Other methods that can be used include error-prone PCR, phage display and region-directed mutagenesis.

Mutagenesis/shuffling methods can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides expressed by host cells. Mutagenized DNA molecules that encode 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.

Semi-synthetic gene construction is accomplished by combining aspects of synthetic gene construction, and/or site-directed mutagenesis, and/or random mutagenesis, and/or shuffling. Semi-synthetic construction is typified by a process utilizing polynucleotide fragments that are synthesized, in combination with PCR techniques. Defined regions of genes may thus be synthesized de novo, while other regions may be amplified using site-specific mutagenic primers, while yet other regions may be subjected to error-prone PCR or non-error prone PCR amplification. Polynucleotide subsequences may then be shuffled.

In a particular embodiment, the detergent composition includes a mixture of one or more nonionic surfactants and one or more anionic surfactants. The surfactant(s) is typically present at a level of from about 0.1% to about 60% by weight, such as from about 1% to about 40%, or from about 3% to about 20%, or from about 3% to about 10%. The surfactant(s) is chosen based on the desired cleaning application, and includes any conventional surfactant(s) known in the art. Any surfactant known in the art for use in detergents may be utilized. Surfactants lower the surface tension in the detergent, which allows the stain being cleaned to be lifted and dispersed and then washed away.

When included therein the detergent will usually contain from about 1% to about 40% by weight, such as from about 5% to about 30%, including from about 5% to about 15%, or from about 20% to about 25% of an anionic surfactant.

When included therein the detergent will usually contain from about 0% to about 10% by weight of a zwitterionic surfactant. Non-limiting examples of zwitterionic surfactants include betaine, alkyldimethylbetaine, sulfobetaine, and combinations thereof.

Hydrotropes

A hydrotrope is a compound that solubilizes hydrophobic compounds in aqueous solutions (or oppositely, polar substances in a non-polar environment). Typically, hydrotropes have both hydrophilic and hydrophobic characters (so-called amphiphilic properties as known from surfactants); however the molecular structure of hydrotropes generally do not favor spontaneous self-aggregation. Hydrotropes do not display a critical concentration above which self-aggregation occurs as found for surfactants and lipids forming miceller, lamellar or other well defined meso-phases. Instead, many hydrotropes show a continuous-type aggregation process where the sizes of aggregates grow as concentration increases. However, many hydrotropes alter the phase behavior, stability, and colloidal properties of systems containing substances of polar and non-polar character, including mixtures of water, oil, surfactants, and polymers. Hydrotropes are classically used across industries from pharma, personal care, food, to technical applications. Use of hydrotropes in detergent compositions allows for example more concentrated formulations of surfactants (as in the process of compacting liquid detergents by removing water) without inducing undesired phenomena such as phase separation or high viscosity.

The detergent may contain from 0 to about 5% by weight, such as from about 0.5 to about 5%, or from about 3% to about 5%, of a hydrotrope. Any hydrotrope known in the art for use in detergents may be utilized.

Builders and Co-Builders

The detergent composition may contain from 0 to about 65% by weight, such as from about 5% to about 45% of a detergent builder or co-builder, or a mixture thereof. In a dish wash detergent, the level of builder is typically from about 40 to about 65%, particularly from about 50 to about 65%. Builders and chelators soften, e.g., the wash water by removing the metal ions form the liquid. The builder and/or co-builder may particularly be a chelating agent that forms water-soluble complexes with Ca and Mg. Any builder and/or co-builder known in the art for use in laundry detergents may be utilized. Non-limiting examples of builders include zeolites, diphosphates (pyrophosphates), triphosphates such as sodium triphosphate (STP or STPP), carbonates such as sodium carbonate, soluble silicates such as sodium metasilicate, layered silicates (e.g., SKS-6 from Hoechst), ethanolamines such as 2-aminoethan-1-ol (MEA), diethanolamine (DEA, also known as iminodiethanol), triethanolamine (TEA, also known as 2,2′,2″-nitrilotriethanol), and carboxymethyl inulin (CMI), and combinations thereof.

The detergent composition may also contain from 0 to about 20% by weight, such as from about 5% to about 10%, of a detergent co-builder, or a mixture thereof. The detergent composition may include a co-builder alone, or in combination with a builder, for example a zeolite builder. Non-limiting examples of co-builders include homopolymers of polyacrylates or copolymers thereof, such as poly(acrylic acid) (PAA) or copoly(acrylic acid/maleic acid) (PAA/PMA).

Bleaching Systems

The detergent may contain from 0 to about 50% by weight, such as from about 0.1% to about 25%, of a bleaching system. Bleach systems remove discolor often by oxidation, and many bleaches also have strong bactericidal properties, and are used for disinfecting and sterilizing. Any bleaching system known in the art for use in laundry detergents may be utilized. Suitable bleaching system components include bleaching catalysts, photobleaches, bleach activators, sources of hydrogen peroxide such as sodium percarbonate and sodium perborates, preformed peracids and mixtures thereof. Suitable preformed peracids include, but are not limited to, peroxycarboxylic acids and salts, percarbonic acids and salts, perimidic acids and salts, peroxymonosulfuric acids and salts, for example, Oxone (R), and mixtures thereof. Non-limiting examples of bleaching systems include peroxide-based bleaching systems, which may comprise, for example, an inorganic salt, including alkali metal salts such as sodium salts of perborate (usually mono- or tetra-hydrate), percarbonate, persulfate, perphosphate, persilicate salts, in combination with a peracid-forming bleach activator. The term bleach activator is meant herein as a compound which reacts with peroxygen bleach like hydrogen peroxide to form a peracid. The peracid thus formed constitutes the activated bleach. Suitable bleach activators to be used herein include those belonging to the class of esters amides, imides or anhydrides. Suitable examples are tetracetylethylene diamine (TAED), sodium 4-[(3,5,5-trimethylhexanoyl)oxy]benzene sulfonate (ISONOBS), diperoxy dodecanoic acid, 4-(dodecanoyloxy)benzenesulfonate (LOBS), 4-(decanoyloxy)benzenesulfonate, 4-(decanoyloxy)benzoate (DOB S), 4-(nonanoyloxy)-benzenesulfonate (NOBS), and/or those disclosed in WO 98/17767. A particular family of bleach activators of interest was disclosed in EP 624154 and particulary preferred in that family is acetyl triethyl citrate (ATC). ATC or a short chain triglyceride like triacetin has the advantage that it is environmental friendly as it eventually degrades into citric acid and alcohol. Furthermore acetyl triethyl citrate and triacetin has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator. Finally ATC provides a good building capacity to the laundry additive. Alternatively, the bleaching system may comprise peroxyacids of, for example, the amide, imide, or sulfone type. The bleaching system may also comprise peracids such as 6-(phthalimido)peroxyhexanoic acid (PAP). The bleaching system may also include a bleach catalyst. In some embodiments the bleach component may be an organic catalyst selected from the group of organic catalysts having the following formula:

When the components of detergent compositions change new enzyme activities or new enzymes having alternative and/or improved properties compared to the common used detergent enzymes such as proteases, lipases and amylases is needed to achieve a similar or improved wash performance when compared to the traditional detergent compositions.

The present disclosure further concerns the use of compositions of the present disclosure comprising the subtilase in a proteinaceous stain removing processes. The proteinaceous stains may be stains such as, e.g., baby food, sebum, cocoa, egg, blood, milk, ink, grass, or a combination thereof.

Typical detergent compositions include various components in addition to the enzymes, these components have different effects, some components like the surfactants lower the surface tension in the detergent, which allows the stain being cleaned to be lifted and dispersed and then washed away, other components like bleach systems remove discolor often by oxidation and many bleaches also have strong bactericidal properties, and are used for disinfecting and sterilizing. Yet other components like builder and chelator softens, e.g., the wash water by removing the metal ions form the liquid.

In a particular embodiment, the present disclosure concerns the use of a composition comprising a subtilase variant and one or more detergent components, such as surfactants, hydrotropes, builders, co-builders, chelators or chelating agents, bleaching system or bleach components, polymers, fabric hueing agents, fabric conditioners, foam boosters, suds suppressors, dispersants, dye transfer inhibitors, fluorescent whitening agents, perfume, optical brighteners, bactericides, fungicides, soil suspending agents, soil release polymers, anti-redeposition agents, enzyme inhibitors or stabilizers, enzyme activators, antioxidants, and solubilizers.

In a particular embodiment, the present disclosure concerns the use of a composition of the present disclosure comprising a subtilase variant as disclosed herein and one or more additional enzymes selected from the group comprising of proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidaes, haloperoxygenases, catalases and mannanases, or any mixture thereof.

In a particular embodiment, the present disclosure concerns the use of a composition of the present disclosure comprising a subtilase variant as disclosed herein, one or more additional enzymes selected from the group comprising of proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidaes, haloperoxygenases, catalases and mannanases, or any mixture thereof and one or more detergent components, such as surfactants, hydrotropes, builders, co-builders, chelators or chelating agents, bleaching system or bleach components, polymers, fabric hueing agents, fabric conditioners, foam boosters, suds suppressors, dispersants, dye transfer inhibitors, fluorescent whitening agents, perfume, optical brighteners, bactericides, fungicides, soil suspending agents, soil release polymers, anti-redeposition agents, enzyme inhibitors or stabilizers, enzyme activators, antioxidants, and solubilizers.

Also contemplated are compositions and methods of treating fabrics (e.g., to desize a textile) using one or more of the protease of the present disclosure. The protease can be used in any fabric-treating method which is well known in the art (see, e.g., U.S. Pat. No. 6,077,316). For example, in one aspect, the feel and appearance of a fabric is improved by a method comprising contacting the fabric with a protease in a solution. In one aspect, the fabric is treated with the solution under pressure.

The detergent compositions of the present disclosure are suited for use in laundry and hard surface applications, including dish wash. Accordingly, the present disclosure includes a method for laundering a fabric or washing dishware. The method comprises the steps of contacting the fabric/dishware to be cleaned with a solution comprising the detergent composition as contemplated herein. The fabric may comprise any fabric capable of being laundered in normal consumer use conditions. The dishware may comprise any dishware such as crockery, cutlery, ceramics, plastics such as melamine, metals, china, glass and acrylics. The solution preferably has a pH from about 5.5 to about 11.5. The compositions may be employed at concentrations from about 100 ppm, preferably 500 ppm to about 15,000 ppm in solution. The water temperatures typically range from about 5° C. to about 95° C., including about 10° C., about 15° C., about 20° C., about 25° C., about 30° C., about 35° C., about 40° C., about 45° C., about 50° C., about 55° C., about 60° C., about 65° C., about 70° C., about 75° C., about 80° C., about 85° C. and about 90° C. The water to fabric ratio is typically from about 1:1 to about 30:1.

The enzyme(s) of the detergent composition of the present disclosure may be stabilized using conventional stabilizing agents and protease inhibitors, e.g., a polyol such as propylene glycol or glycerol, a sugar or sugar alcohol, different salts such as NaCl; KCl; lactic acid, formic acid, boric acid, or a boric acid derivative, e.g., an aromatic borate ester, or a phenyl boronic acid derivative such as 4-formylphenyl boronic acid, or a peptide aldehyde such as di-, tri- or tetrapeptide aldehydes or aldehyde analogues (either of the form B1-B0-R wherein, R is H, CH3, CX3, CHX2, or CH2X (X=halogen), B0 is a single amino acid residue (preferably with an optionally substituted aliphatic or aromatic side chain); and B1 of one or more amino acid residues (preferably one, two or three), optionally comprising an N-terminal protection group, or as described in WO 2009/118375, WO 98/13459) or a protease inhibitor of the protein type such as RASI, BASI, WASI (bifunctional alpha-amylase/subtilisin inhibitors of rice, barley and wheat) or Cl2 or SSI.

In some preferred embodiments, granular or liquid laundry products are formulated to have a pH from about 6 to about 8. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, acids, etc., and are well known to those skilled in the art.

The present disclosure is further described by the following examples that should not be construed as limiting the scope of the present disclosure.

EXAMPLES
Example 1: Construction of Variants by Site-Directed Mutagenesis

Site-directed variants were constructed of subtilisin 309 (SEQ ID NO: 1) comprising specific substitutions as contemplated herein. The variants were made by traditional cloning of DNA fragments (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor, 1989) using PCR together with properly designed mutagenic oligonucleotides that introduced the desired mutations in the resulting sequence.

Mutagenic oligos were synthesized corresponding to the DNA sequence flanking the desired site(s) of mutation, separated by the DNA base pairs defining the insertions/deletions/substitutions. In this manner, the variants listed in Table 1 below were constructed and produced.

In order to test subtilisin 309 variants of the present disclosure, the mutated DNA comprising a variant of the present disclosure was transformed into a competent B. subtilis strain, fermented using standard protocols (PS-1 media, 3-4 days, 37° C.) and purified.

Example 2: Wash Testing of Variants by Automatic Mechanical Stress Assay (AMSA)

Washing experiments were performed in order to assess the wash performance of selected protease variants in laundry detergent. The proteases of the present application were tested using the Automatic Mechanical Stress Assay (AMSA). With the AMSA, the wash performance of many small volume enzyme-detergent solutions can be examined. The AMSA plate has a number of slots for test solutions and a lid that firmly squeezes a textile swatch to be washed against the slot openings. During the wash, the plate, test solutions, soiled textile swatch and lid are vigorously shaken to bring the test solution in contact with the soiled textile swatch and apply mechanical stress in a regular, periodic oscillating manner. For further description see WO 02/42740 especially the paragraph “Special method embodiments” at pages 23-24.

Model detergent and test materials were as provided in Table 2A:

Water hardness was adjusted to 16° dH by addition of CaCl₂, MgCl₂, and NaHCO₃(Ca²⁺:Mg²⁺:CO₃²⁻=5:1:6) to the test system. After washing the textile swatches were flushed in tap water and dried.

The performance of an enzyme variant was measured as the brightness of the color of the textile washed with that specific protease. Brightness can also be expressed as the intensity of the light reflected from the sample when illuminated with white light. When the sample is stained the intensity of the reflected light is lower, than that of a clean sample. Therefore the intensity of the reflected light can be used to measure wash performance of a protease. Color measurements were made with a professional flatbed scanner (EPSON EXPRESSION 10000XL, Atea A/S, Lautrupvang 6, 2750 Ballerup, Denmark), which was used to capture an image of the washed melamine tiles.

To extract a value for the light intensity from the scanned images, a special designed software application was used (Novozymes Colour Vector Analyzer). The program retrieves the 24 bit pixel values from the image and converts them into values for red, green and blue (RGB). The intensity value (Int) was calculated by adding the RGB values together as vectors and then taking the length of the resulting vector:

Int=√{square root over (r²+g²+b²)}.

Textiles

Standard chocolate milk and soot textile swatches (PC-03) were obtained from the Center For Testmaterials BV, P.O. Box 120, 3133 KT Vlaardingen, the Netherlands.

The variants had a significantly better wash performance than the parent backbone.

Example 3

The wash performance of variants in detergents was determined by using the following standardized stains obtainable from CFT (Center for Testmaterials) B.V., Vlaardingen, Netherlands:

A: chocolate-milk/ink on cotton: product no. C3

B: chocolate-milk/ink on polyester/cotton: product no. PC3

C: blood-milk/ink on cotton: product no. C5

D: blood-milk/ink on polyester/cotton: product no. PC5

E: peanut oil pigment/ink on cotton: product no. C10

F: egg/pigment on cotton: product no. CS37

Furthermore the following stain obtainable from Eidgenössische Material- and Prüfanstalt (EMPA) was used:

G: grass on cotton: product no. 164

A liquid washing agent with the following composition was used as base formulation (all values in weight percent): from about 0 to about 0.5% xanthan gum, from about 0.2 to about 0.4% antifoaming agent, from about 0.2 to about 8% Triethanolamine, from about 1 to about 7% glycerol, from about 0.3 to about 3% ethanol, from about 0 to about 12% FAEOS (fatty alcohol ether sulfate), from about 1 to about 28% nonionic surfactants, from v0.5-about 4% boric acid, from about 0.5 to about 6% sodium citrate (dihydrate), from about 1 to about 6% soda, from about 0 to about 16% coconut fatty acid, from about 0.5 to about 6% HEDP (1-hydroxyethane-(1,1-diphosphonic acid)), from about 0 to about 0.4% PVP (polyvinylpyrrolidone), from about 0 to about 0.05% optical brighteners, from about 0 to about 0.001% dye, remainder deionized water.

Based on this base formulation, various detergents were prepared by adding respective proteases as indicated in table 7a) and b). Reference is the protease Subtilisin 309 that has the amino acid sequence as shown in SEQ ID NO.1, the reference protease already showing a good wash performance, especially in liquid detergents. The proteases were added in the same amounts based on total protein content (5 mg/l wash liquor).

The dosing ratio of the liquid washing agent was 4.7 grams per liter of washing liquor and the washing procedure was performed for 60 minutes at a temperature of 20° C. and 40° C., the water having a water hardness between about 15.5 and about 16.5° (German degrees of hardness).

The whiteness, i.e. the brightening of the stains, was determined photometrically as an indication of wash performance. A Minolta CM508d spectrometer device was used, which was calibrated beforehand using a white standard provided with the unit.

The results obtained are the difference values between the remission units obtained with the detergents and the remission units obtained with the detergent containing the reference protease. A positive value therefore indicates an improved wash performance of the variants in the detergent. It is evident from tables 7a (results at 40° C.) and 7b (results at 20° C.) that variants as contemplated herein show improved wash performance.
