Description

Technical Field

[0001] The present invention belongs to the field of automatic dishwashing compositions.

Background Art

[0002] Protease (also known as proteinase) is an enzyme having the ability to break down other proteins. Protease has the ability to perform proteolysis, which initiates protein catabolism by hydrolysis of peptide bonds that link amino acids together in a peptide or polypeptide chain that forms a protein. This activity of protease as a protein digestive enzyme is called proteolytic activity. There are many well-known procedures for measuring proteolytic activity (Kalisz, "Microbial Proteinases" in Fiechter (ed.), Advances in Biochemical Engineering / Biotechnology, (1988)). For example, proteolytic activity can be confirmed by a comparative assay that analyzes the ability of each protease to hydrolyze a commercially available substrate. Exemplary substrates useful in the analysis of protease or proteolytic activity include, but are not limited to, dimethyl casein (Sigma C-9801), bovine collagen (Sigma C-9879), bovine elastin (Sigma E-1625), and Keratin Azure (Sigma-Aldrich K8500). Colorimetric assays using these substrates are well known in the art (see, for example, International Publication No. 99 / 34011 and U.S. Patent No. 6,376,450, both of which are incorporated herein by reference).

[0003] Serine proteases are enzymes (EC number 3.4.21) that have a serine active site that initiates the hydrolysis of peptide bonds in proteins. Serine proteases comprise a diverse class of enzymes with a wide range of specificities and biological functions, which are further classified into chymotrypsin-like (trypsin-like) and subtilisin-like based on their structure. The prototypic subtilisin (EC number 3.4.21.62) was first obtained from Bacillus subtilis. Subtilisins and their homologs are members of the S8 peptidase family in the MEROPS classification scheme (Rawlings, ND et al (2016) Twenty years of the MEROPS database of proteolytic enzymes, their substrates and inhibitors. Nucleic Acids Res 44, D343-D350). Members of family S8 have three catalytic residues in their amino acid sequence in the order Asp, His, and Ser. [Prior art documents] [Patent Documents]

[0006] While many useful mutant proteases have been developed for washing applications, improved protease mutants are still needed.

[0007] There is still a need for improved protease variants that have improved stability during the manufacture of the variants, during the storage of compositions containing the variants, and during use (e.g., in washing baths), particularly in oxidizing environments, including when the variants are used in combination with bleaching agents.

[0008] There is still a need to provide an automatic dishwashing detergent composition that can provide good cleaning and have good stability.

[0009] Furthermore, there remains a need to provide an automatic dishwashing composition in the form of a water-soluble unit dose pouch containing compartments, wherein the compartments contain both powder and gel components, the composition contains a surfactant and a protease, and the composition has good washing performance, good protease performance, and good stability. [Means for solving the problem]

[0010] The present invention relates to an automatic dishwashing composition comprising a surfactant and a protease, The automatic dishwashing composition is in the form of a water-soluble unit dose pouch containing compartments, each compartment containing both powder and gel components. Regarding the protease in relation to SEQ ID NO: 1, (i) The mutation at position 122, (ii) One or more mutations at positions 126, 127, 128, 211 and 212 and This invention relates to an automatic dishwashing composition that contains a subtilisin variant. [Modes for carrying out the invention]

[0011] Automatic dishwashing composition The automatic dishwashing composition contains a surfactant and a protease.

[0012] The automatic dishwashing composition is in the form of a water-soluble unit-dose pouch containing compartments, and the compartments contain both a powder component and a gel component.

[0013] Preferably, the composition is in the form of a multi-compartment pouch containing two or more compartments, preferably three or more compartments. At least one of the compartments contains both a powder component and a gel component.

[0014] Protease may be present in the gel component.

[0015] The composition may contain a bleaching agent, and the bleaching agent is present in the powder component.

[0016] The composition of the present invention is very well suited for providing in the form of a multi-compartment pack, more specifically, a multi-compartment pack containing compartments having compositions in different physical forms, for example, a compartment containing a composition in solid form and another compartment containing a composition in liquid form. The composition is preferably enclosed in a water-soluble film such as polyvinyl alcohol. A unit-dose form of the composition wrapped in a polyvinyl alcohol film with a thickness of less than 100 μm, preferably 20 - 90 μm, is particularly preferred. The detergent composition of the present invention has a weight of about 8 to about 25 grams, preferably about 10 to about 20 grams. This weight range fits well with a margin in the dispenser of a dishwashing machine. Although this range corresponds to a small amount as a detergent, the detergent is formulated to provide all the effects as described above herein.

[0017] The composition is preferably phosphate-free. As used herein, "phosphate-free" is understood to mean that the composition contains less than 1% by weight, preferably less than 0.1% by weight, of phosphate.

[0018] The composition is typically a detergent composition. The term "detergent composition" or "detergent formulation" is used in relation to a composition intended for use in a cleaning medium to clean a soiled or dirty object. In some embodiments, the detergents of the present disclosure include one or more of the subtilisin variants described herein, and in addition, one or more surfactants, transferases, hydrolases, oxidoreductases, builders (e.g., builder salts), bleaches, bleach activators, blueing agents, fluorescent dyes, anti-caking agents, masking agents, enzyme stabilizers, calcium, enzyme activators, antioxidants, and / or solubilizing agents. In some cases, the builder salt is a mixture of silicate and phosphate, and preferably there is more silicate (e.g., sodium metasilicate) than phosphate (e.g., sodium tripolyphosphate). Some embodiments relate to cleaning compositions or detergent compositions that do not contain any phosphate (e.g., phosphate or phosphate builder).

[0019] The term "auxiliary substance" refers to any liquid, solid, or gaseous substance contained in the cleaning composition other than one or more of the subtilisin variants described herein, or their recombinant polypeptides or active fragments. In some embodiments, the cleaning compositions of the present disclosure include one or more cleaning auxiliary substances. Each cleaning auxiliary substance is typically selected according to the particular type and form of the cleaning composition (e.g., liquid, granule, powder, bar, paste, spray, tablet, gel, foam, or other composition). Preferably, each cleaning auxiliary substance is compatible with the protease enzyme used in the composition.

[0020] The phrases "composition substantially free of boron" or "detergent substantially free of boron" refer, respectively, to compositions or detergents that contain trace amounts of boron, e.g., less than about 1000 ppm (1 mg / kg or liter is equal to 1 ppm), less than about 100 ppm, less than about 50 ppm, less than about 10 ppm, or less than about 5 ppm, or less than about 1 ppm, possibly containing boron from other composition or detergent components.

[0021] The term "bleaching" refers to treating a material (e.g., fabric, laundry, pulp, etc.) or surface for a sufficient length of time and / or under appropriate pH and / or temperature conditions to whiten (i.e., whiten) and / or clean the material. Examples of chemicals suitable for bleaching include, but are not limited to, ClO2, H2O2, peracids, and NO2. Examples of bleaching agents include enzymatic bleaching agents such as perhydrolases and arylesterases. Another embodiment relates to a composition comprising one or more subtilisin variants described herein and one or more perhydrolases, such as those described in International Publication Nos. 2005 / 056782, 2007 / 106293, 2008 / 063400, 2008 / 106214, and 2008 / 106215.

[0022] The term “cleaning performance” of a protease (e.g., one or more subtilisin variants described herein, or their recombinant polypeptides or active fragments) refers to the contribution of one or more subtilisin variants described herein to the cleaning performance of a detergent, compared to a detergent without one or more subtilisin variants described herein added to the composition. Cleaning performance is compared under relevant cleaning conditions. In some test systems, detergent composition, foam concentration, water hardness, cleaning mechanism, time, pH, and / or temperature, and other relevant factors, can be controlled to mimic conditions typical of household use in a particular market segment (e.g., automatic dishwashers, dishwashers, tableware washers, etc.).

[0023] The term “relevant washing conditions” is used herein to refer to the conditions actually used in households within the market segments of hand dishwashers, automatic dishwashers, or laundry detergents, particularly washing temperature, time, washing mechanism, foam concentration, detergent type, and water hardness.

[0024] The term "dishwashing" refers to both household and industrial dishwashing, and encompasses both automated dishwashing (e.g., in dishwashers).

[0025] The term "disinfection" refers to the removal of contaminants from a surface, as well as the inhibition or killing of microorganisms on the surface of an object.

[0026] The term “compact” form of a cleaning composition as used herein best reflects its density and, in terms of composition, its amount of inorganic filler salts. Inorganic filler salts are conventional components of detergent compositions in powder form. In conventional detergent compositions, filler salts are present in substantial amounts, typically about 17 to about 35% by weight of the total composition. In contrast, in compact compositions, filler salts are present in amounts not exceeding about 15% of the total composition. In some embodiments, filler salts are present in amounts not exceeding about 10% by weight of the composition, or more preferably about 5% by weight. In some embodiments, the inorganic filler salts are selected from alkali metal salts and alkaline earth metal salts of sulfates and chlorides. In some embodiments, the filler salt is sodium sulfate.

[0027] Gel components The gel component may also be referred to herein as gel, gel-like phase, or gel phase.

[0028] The gel component is preferably anhydrous. Anhydrous means containing less than 10% by weight, or less than 8% by weight, or less than 6% by weight, or less than 4% by weight, or less than 2% by weight, or less than 1% by weight of water, or not containing any intentionally added water.

[0029] The gel components typically contain enzymes, typically proteases, and, if present, typically amylase as well.

[0030] The gel components may include enzymes selected from proteases, amylases, lipases, hemicellulases, cellulases, perhydrolases, or oxidoreductases, and combinations thereof.

[0031] Typically, a gel component should be understood as a composition / phase having an internal structured network. This internal structured (spatial) network is formed by dispersing a solid but distributed substance, long or highly branched particles, and / or a gelling agent in at least one liquid (at least one liquid being liquid at 20°C). Such a gel phase behaves thermally reversibly.

[0032] This gel phase may be, for example, fluid or dimensionally stable. However, according to the present invention, the gel-like phase is preferably dimensionally stable at room temperature. In preparation, a gel-forming agent, preferably xanthan gum, gelatin, or polyvinyl alcohol and / or derivatives thereof, is brought into contact with a solvent, preferably an organic solvent, preferably one or more polyhydric alcohols. This yields a fluid mixture that can be formed into a desired shape. After a certain period of time, a gel phase is obtained that remains in the predetermined shape, i.e., dimensionally stable. This time, i.e., the solidification time, is preferably 15 minutes or less, preferably 10 minutes or less, and particularly preferably 5 minutes or less. At the same time, at least one gel phase yields to pressure but does not deform as a result and returns to its initial state after the pressure is stopped. At least one gel phase is preferably elastic, particularly linearly elastic.

[0033] At least one gel phase is preferably a molded body. A molded body is a single body that stabilizes itself in an applied shape. This dimensionally stable body is formed from a molding material (e.g., a composition) by shaping this molding material in a targeted manner, for example, by injecting a liquid composition into a mold and then curing the liquid composition within the scope of a sol-gel process. Certain minimum requirements are imposed on the formulation of at least one gel phase. Thus, as already stated, the gel phase must solidify as quickly as possible. Longer solidification times result in longer manufacturing times and, consequently, higher costs. According to the present invention, solidification time means the period during which at least one gel phase changes from a free-flowing state to a dimensionally stable state that does not free-flow at room temperature during preparation. This is below room temperature, typically 20°C.

[0034] At least one gel phase is preferably a solid gel phase. In this case, it is cut-resistant. For example, it can be cut with a knife after solidification, and apart from the cut made, it will not be further damaged.

[0035] In addition, at least one gel phase is preferably translucent or transparent, resulting in a good optical impression. The transmittance of the gel phase (without dye) is preferably in the range of 100% to 20%, 100% to 30%, and particularly 100% to 40%. To measure the light transmittance (transmittance), the transmittance (%) at 600 nm was determined relative to water at 20°C as a reference. For this purpose, the composition was poured into a prepared 11 mm round cuvette and measured by length using a LICO 300 colorimeter after 12 hours of storage at room temperature.

[0036] At least one gel phase has low water content. For the purposes of the present invention, low water content means that a small amount of water can be used to prepare at least one gel phase. The percentage of water in the gel phase is particularly 20% by weight or less, preferably 15% by weight or less, particularly 12% by weight or less, and particularly 10-5% by weight. The weight percentage data is based on the total weight of the gel phase. This has the advantage that a small amount of water combined with PVOH can have a structure-forming or gel-forming effect.

[0037] According to a preferred embodiment, at least one gel phase is essentially anhydrous. This means that the gel phase is preferably essentially water-free. Here, "substantially water-free" means that a small amount of water may be present in the gel phase. This water can be introduced into the phase, for example, by a solvent, or as crystal water, or by reactions between the phase components. However, since a solvent is used for the preparation of the gel phase, it is preferable that only a small amount, and especially no water, is present. In this embodiment, the percentage of water in the gel phase is 4.9% by weight or less, 4% by weight or less, preferably 2% by weight or less, particularly 1% by weight or less, particularly 0.5% by weight or less, particularly 0.1% by weight or less, or 0.05% by weight or less. The weight percentage is based on the total weight of the gel phase.

[0038] The gel component typically contains a gel-forming agent, preferably selected from gelatin, xanthan gum and / or polyvinyl alcohol, particularly gelatin or polyvinyl alcohol, particularly preferably polyvinyl alcohol, in an amount of 4 to 40% by weight, particularly 6 to 30% by weight, particularly preferably 7 to 24% by weight, very particularly preferably 8 to 22% by weight, particularly, for example, 14 to 20% by weight, based on the total weight of the gel-like phase.

[0039] Preferably, at least one gel phase contains PVOH (polyvinyl alcohol) and / or its derivatives. Polyvinyl alcohol is a thermoplastic substance that is usually prepared as a white to yellowish powder by hydrolysis of polyvinyl acetate. Polyvinyl alcohol (PVOH) is resistant to almost all anhydride organic compounds.

[0040] Polyvinyl alcohol having a molar mass of 30,000 to 60,000 g / mol is preferred.

[0041] Preferred PVOH derivatives for the purposes of the present invention are copolymers of polyvinyl alcohol with other monomers, particularly copolymers with anionic monomers. Preferred anionic monomers are preferably vinyl acetic acid, alkyl acrylates, maleic acid and its derivatives, particularly monoalkyl maleate (particularly monomethyl maleate), dialkyl maleate (particularly dimethyl maleate), maleic anhydride, fumaric acid and its derivatives, particularly monoalkyl fumarate (particularly monomethyl fumarate), dialkyl fumarate (particularly dimethyl fumarate), fumaric anhydride, itaconic acid and its derivatives, particularly dialkyl itaconic acid, dimethyl itaconic acid, itaconic anhydride, citraconic acid (methyl maleic acid) and its derivatives, monoalkyl citraconic acid (particularly methyl citraconic acid), monoalkyl citraconic acid (particularly methyl citraconic acid), Dialkylcitraconate (dimethyl citraconate), citraconate anhydride, mesaconic acid (methyl fumaric acid) and its derivatives, monoalkyl mesaconic acid, dialkyl mesaconic acid, mesaconic acid anhydride, glutaconic acid and its derivatives, monoalkyl glutaconate, dialkyl glutaconate, glutaconic acid anhydride, vinyl sulfonic acid, alkyl sulfonic acid, ethylene sulfonic acid, 2-acrylamido-1-methylpropanesulfonic acid, 2-acrylamido-2-methylpropanesulfonic acid, 2-methylacrylamido-2-methylpropanesulfonic acid, 2-sulfoethyl acrylate, and combinations thereof, as well as alkali metal salts or esters of the above monomers. Particularly preferred derivatives of PVOH are copolymers of polyvinyl alcohol with monomers selected from the group consisting of monoalkyl maleate (especially monomethyl maleate), dialkyl maleate (especially dimethyl maleate), maleic anhydride, and combinations thereof, as well as alkali metal salts or esters of the above monomers. The values ​​given to the polyvinyl alcohol itself are applicable to preferred molecular weights. For the purposes of the present invention, it is preferable that at least one gel phase contains by weight polyvinyl alcohol and / or its derivatives, preferably polyvinyl alcohol having a degree of hydrolysis of preferably 70-100 mol%, particularly 80-90 mol%, particularly preferably 81-89 mol%, and particularly 82-88 mol%.

[0042] Particularly preferred is polyvinyl alcohol as a white-yellowish powder or granule having a degree of polymerization in the range of about 100 to 2500 (molar mass of about 4000 to 100,000 g / mol) and a degree of hydrolysis of 80 to 99 mol%, preferably 85 to 90 mol%, particularly 87 to 89 mol%, for example 88 mol%, and containing a corresponding residual content of acetyl groups.

[0043] PVOH powders having the above properties suitable for use in at least one gel phase are sold by Kuraray, for example, under the names Mowiol® or Poval®. Exceval® AQ4104 from Kuraray is also suitable, for example. Particularly preferred are Mowiol C30 from Kuraray, Poval® quality, especially quality 3-83, 3-88, 6-88, 4-85, particularly preferably 4-88, very preferably Poval 4-88 S2, and Mowiol® 4-88.

[0044] The water solubility of polyvinyl alcohol can be determined by post-treatment with aldehydes (acetalization) or ketones (ketalization). Polyvinyl alcohol acetalized or ketalized with aldehyde or keto groups of sugars or polysaccharides or mixtures thereof has been proven particularly preferred and advantageous due to their extremely good solubility in cold water. The reaction products of polyvinyl alcohol and starch can be used very advantageously. Furthermore, the solubility in water can be altered by complexing with Ni or Cu salts, or by treatment with dichromate, boric acid, or borax, and thus adjusted to the desired value in the target manner.

[0045] In preferred embodiments, at least one or more enzymes, preferably the protease variants of the present invention, are not introduced into a gel phase, particularly a gel phase containing a gel-forming agent, as a liquid enzyme preparation. It is particularly preferable that the liquid enzyme preparation is not introduced into a gel phase in which the gel-forming agent is selected from gelatin, xanthan gum and / or polyvinyl alcohol, particularly gelatin or polyvinyl alcohol, particularly preferably polyvinyl alcohol. In particular, in the preparation of a PVOH-containing gel phase, the introduction of the liquid enzyme preparation into a gel phase that has been heated by the preparation is performed at a high temperature, which results in a considerable decrease in the stability of the enzyme in the liquid enzyme preparation. This decrease in stability means that the enzyme activity is significantly lower compared to the starting preparation. This decrease in stability can be measured, for example, by measuring the residual enzyme activity, or by comparing the purification performance of the corresponding enzyme, particularly according to IHF standards. The enzyme is particularly preferably incorporated into the gel phase as granules.

[0046] PVOH is particularly suitable for preparing a gel phase that satisfies the above requirements. Therefore, in addition to at least one enzyme, particularly preferably selected from the group of enzymes, proteases and / or amylases, at least one enzyme granule, PVOH, and at least one polyhydric alcohol, at least one gel phase is particularly preferred. Particularly preferred, at least one gel phase comprises at least one amylase granule and / or at least one protease granule, PVOH, and at least one polyhydric alcohol.

[0047] According to the present invention, at least one gel phase preferably contains at least one enzyme, preferably at least one enzyme granule, preferably at least one amylase granule and / or at least one protease granule, particularly at least one protease granule, PVOH and / or its derivatives in a proportion of about 4% to 40% by weight, particularly 6% to 30% by weight, preferably 7% to 24% by weight, and most preferably 8% to 22% by weight. Significantly low proportions of PVOH do not result in the formation of a stable gel phase. Each value is based on the total weight of the gel phase.

[0048] These gel phases prepared in this manner have particularly high melting points, are dimensionally stable (even at 40°C), and do not change their shape, or change it only slightly, even during storage. In particular, they also have low reactivity with respect to direct negative interactions with components of granular mixtures.

[0049] In particular, PVOH can also easily produce gel phases that contain little to no water. When PVOH is used as the polymer for at least one gel phase, a low-viscosity melt is produced at 110-120°C, which makes it particularly easy to process. In particular, the gel phase can be introduced into water-soluble coatings quickly and accurately without sticking or inaccurate measurement of volume. Furthermore, these gel phases adhere particularly well to water-soluble coatings, especially when they are similarly produced from PVOH.

[0050] This is also optically advantageous. As a result of the rapid solidification of at least one gel phase using PVOH, further processing of the gel phase can be carried out particularly quickly. Furthermore, the good solubility of the resulting gel phase is particularly favorable for the overall solubility of the detergent. In addition, a gel phase with such a short solidification time is advantageous because at least one solid phase containing granular mixtures, especially powders, that are placed on top of it will not sink into a gel that has not yet completely solidified or a gel that is too soft. This will result in a visually unpleasant detergent portion.

[0051] In particular, in the case of the multiphase disposable portion according to the present invention having at least one solid phase, it is important that at least one gel phase is dimensionally stable, and as a result, the possible interactions between the solid and the gel phase are minimized. If at least one gel phase also contains gelatin in addition to PVOH, the toughness of the gel phase in the preparation increases dramatically.

[0052] The present invention more preferably provides a detergent, preferably a dishwashing detergent, particularly an automatic dishwashing detergent, comprising, in addition to at least one enzyme, preferably at least one enzyme granule, at least one organic solvent selected particularly from 1,2-propanediol, 1,3-propanediol, glycerol, 1,1,1-trimethylolpropane, triethylene glycol, dipropylene glycol, polyethylene glycol and / or mixtures thereof.

[0053] At least one gel phase preferably contains at least one polyhydric alcohol. At least one polyhydric alcohol enables the preparation of a dimensionally stable, non-flowing gel phase within a short solidification time of 15 minutes or less, particularly 10 minutes or less, in addition to the formation of a flowable gel phase. For the purposes of this invention, polyhydric alcohols are hydrocarbons in which two, three or more hydrogen atoms are replaced by OH groups. The OH groups are bonded to different carbon atoms in each case. No carbon atom has two OH groups. This is different from (simple) alcohols in which only one hydrogen atom in the hydrocarbon is replaced by an OH group. Polyhydric alcohols having two OH groups are called alkanediols, and polyhydric alcohols having three OH groups are called alkantriols. Therefore, polyhydric alcohols correspond to the general formula [KWj(OH)X], where KW represents a linear or branched, saturated or unsaturated, substituted or unsubstituted hydrocarbon. Substitution can be, for example, with -SH groups or -NH groups. Preferably, kW is a straight-chain or branched, saturated or unsaturated unsubstituted hydrocarbon. KW contains at least two carbon atoms. Polyhydric alcohols contain two, three or more OH groups (x=2, 3, 4), with only one OH group bonded to each C atom of KW. KW particularly preferably contains 2 to 10 carbon atoms, i.e., 2, 3, 4, 5, 6, 7, 8, 9, or 10 carbon atoms. Polyhydric alcohols with x=2, 3, or 4 (e.g., pentaerythritol with x=4) can be particularly used. Preferably, x=2 (alkanediol) and / or x=3 (alkanetriol).

[0054] Particularly preferably, at least one gel phase contains, as a polyhydric alcohol, at least one alkanetriol and / or at least one alkanediol, particularly at least one C3-~C10-alkanetriol and / or at least one C3-~C10-alkanediol, preferably at least one C3-~Cs-alkanetriol and / or at least one C3-~Cs-alkanediol, particularly at least one C3-~C6-alkanetriol and / or at least one C3-~C5-alkanediol. Preferably, at least one polyhydric alcohol contains an alkanetriol and an alkanediol. Therefore, in a preferred embodiment, at least one gel phase contains at least one polymer, particularly PVOH or PVOH having gelatin, and at least one alkanediol and at least one alkanetriol, particularly alkanetriol and alkanediol. Similarly, a gel phase comprising at least one polymer, PVOH or PVOH having gelatin, and C3-~Cs-alkanediols and C3-~Cs-alkanetriols is preferred. Furthermore, a gel phase comprising at least one polymer, particularly PVOH or PVOH having gelatin, and C3-~Cs-alkanediols and C3-~C6-alkanetriols is preferred. According to the present invention, polyhydric alcohols do not include any derivatives thereof such as ethers or esters.

[0055] It was found that particularly short solidification times can be achieved when the corresponding triol (alkanetriol) is combined with the corresponding diol (alkanediol). Furthermore, the resulting gel phase is transparent and has a glossy surface that provides an attractive visual impression.

[0056] Preferably, the automatic dishwashing composition contains at least one organic solvent in the gel phase in an amount of 30 to 90% by weight, particularly 40 to 85% by weight, and especially preferably 50 to 80% by weight, based on the total weight of the gel phase.

[0057] The amount of polyhydric alcohol or polyhydric alcohols used in the gel phase according to the present invention is preferably at least 45% by weight, and more preferably 55% by weight or more. Here, the preferred range of the amount is 45% to 85% by weight, and more preferably 50% to 80% by weight, based on the total weight of the gel phase.

[0058] C3-C6-alkanetriolglycerol and / or 2-ethyl-2-(hydroxymethyl)-1,3-propanediol (also known as 1,1,1-trimethylolpropane) and / or 2-amino-2-(hydroxymethyl)-1,3-propanediol (TRIS, trishydroxymethylaminoethane) and / or 1,3,5-pentanetriol are preferred. C.sub.3-C.sub.6-alkanetriolglycerol and / or 2-ethyl-2-(hydroxymethyl)-1,3-propanediol (also known as 1,1-trimethylolpropane) are particularly preferred. C.sub.3-C.sub.5-alkanediols are, for example, 1,5-pentanediol, 3-methyl-1,5-pentanediol, 1,4-butanediol, 1,3-propanediol and / or 1,2-propanediol, preferably 1,3-propanediol and / or 1,2-propanediol. Surprisingly, it has been found that the chain length of the diol, particularly the position of the OH group, affects the transparency of the gel phase. Therefore, the OH group of the diol is preferably not located on directly adjacent carbon atoms. In particular, there are three or four carbon atoms, especially preferably three, between two OH groups of the diol.

[0059] The diol 1,3-propanediol is particularly preferred. Surprisingly, particularly good results were found to be achieved with glycerol and 1,3-propanediol and / or 1,2-propanediol, especially mixtures containing glycerol and 1,3-propanediol.

[0060] According to the present invention, polyethylene glycol having an average molar mass of 200 to 600 g / mol is used in combination with polyvinyl alcohol in at least one or more gel phases, preferably additionally, polyethylene glycol having an average molar mass of about 200 to about 600 g / mol, preferably 300 to 500 g / mol, and particularly preferably 350 to 450 g / mol, for example, about 400 g / mol (INCI:PEG400).

[0061] Suitable polyethylene glycols have an average molar mass of 300-500 g / mol, particularly 350-450 g / mol.

[0062] Furthermore, at least one gel phase preferably comprises additional anionic polymers, particularly polycarboxylates. These can be used as builder and / or thickening polymers. According to the present invention, at least one gel phase may further comprise an anionic polymer or copolymer having builder properties. This is preferably a polycarboxylate. The polycarboxylate used is preferably a copolymer polyacrylate, preferably a sulfopolymer, preferably a copolymer polysulfonate, and preferably a hydrophobic-modified copolymer polysulfonate. The copolymer may have two, three, four, or more different monomer units. A preferred copolymer polysulfonate contains at least one monomer from the group of unsaturated carboxylic acids, in addition to monomers containing sulfonic acid groups.

Where used herein, the singular forms "a," "an," and "the" include the plural form unless explicitly stated in the context. Unless otherwise specified herein, nucleic acid sequences are written from left to right in the 5' to 3' direction, and amino acid sequences are written from left to right in the amino to carboxyl direction. Each numerical range used herein includes any narrower numerical range contained within such broader numerical range as if each of those narrower numerical ranges were explicitly stated herein.

[0065] Where used herein in relation to numerical values, the term “approximately” refers to a range of + / - 0.5 of a numerical value unless the term is specifically defined in the context. For example, the phrase “a pH value of approximately 6” refers to a pH value between 5.5 and 6.5 unless the pH value is specifically defined.

[0066] The nomenclature for amino acid substitutions of one or more subtilisin variants described herein uses one or more of the following: position; position:amino acid substitution; or initial amino acid: position:amino acid substitution. A reference to "position" (e.g., position 5, position 8, position 17, position 22, etc.) includes any initial amino acid that may be present at such a position, and any substitution that may be present at such a position. A reference to "position:amino acid substitution" (e.g., 1S / T / G, 3G, 17T, etc.) includes any initial amino acid that may be present at such a position, and one or more amino acids that may be substituted for such an initial amino acid. References to positions can be enumerated in several forms; for example, position 003 may also be called position 03 or 3. References to initial or substituted amino acids may be further represented as several initial or substituted amino acids separated by forward slashes (" / "). For example, D275S / K indicates that the 275th position is substituted with serine (S) or lysine (K), and P / S197K indicates that the starting amino acid proline (P) or serine (S) at the 197th position is substituted with lysine (K). A reference to X as an amino acid at a given position refers to any amino acid at the listed position.

[0067] The positions of amino acid residues in a given amino acid sequence are numbered in correspondence with the amino acid sequence of SEQ ID NO: 1. That is, the amino acid sequence of SEQ ID NO: 1 serves as a reference sequence for numbering the positions of amino acid residues. For example, the amino acid sequences of one or more subtilisin variants described herein are aligned with the amino acid sequence of SEQ ID NO: 1 using the alignment algorithm described herein, and each amino acid residue in the given amino acid sequence that is aligned (preferably optimally aligned) with the amino acid residues of SEQ ID NO: 1 is conveniently numbered by referring to the numbered position of its corresponding amino acid residue. For example, a sequence alignment algorithm such as those described herein identifies one or more positions in the target sequence where insertions or deletions occur when compared with a query sequence (sometimes called a “reference sequence”). Sequence alignment with other subtilisin amino acid sequences may be determined using, for example, the amino acid alignment provided in Figure 1 of International Application PCT / US 2017 / 062768, filed on November 28, 2018, claiming priority to U.S. Provisional Application No. 62 / 591,976, filed on November 29, 2018, entitled "Highly Stable Subtilisin Enzymes".

[0068] The terms "protease" and "proteinase" refer to enzymes that have the ability to break down proteins and peptides. Proteases have the ability to "protein-digest" by hydrolyzing peptide bonds that link amino acids together in peptide or polypeptide chains that form proteins. This activity of proteases as protein-digesting enzymes is called "protein-digesting activity." Many well-known procedures exist for measuring protein-digesting activity. For example, protein-digesting activity can be confirmed by comparative assays that analyze the ability of each protease to hydrolyze a suitable substrate. Exemplary substrates useful in the analysis of protease or protein-digesting activity include, but are not limited to, dimethylcasein (Sigma C-9801), bovine collagen (Sigma C-9879), bovine elastin (Sigma E-1625), and keratin Azure (Sigma-Aldrich K8500). Colorimetric assays utilizing these substrates are well known in the art (see, for example, International Publication No. 99 / 34011 and U.S. Patent No. 6,376,450). The pNA peptidyl assay (see, for example, Del Mar et al., Anal Biochem, 99:316-320, 1979) is also used to determine the concentration of the active enzyme. This assay measures the rate at which p-nitroaniline is released when the enzyme hydrolyzes a soluble synthetic substrate such as succinyl-alanine-alanine-proline-phenylalanine-p-nitroanilide (suc-AAPF-pNA). The rate of yellow formation from the hydrolysis reaction is measured at 405 or 410 nm with a spectrophotometer and is proportional to the concentration of the active enzyme. Furthermore, the total protein concentration in the purified protein sample can be determined using absorbance measurement at 280 nanometers (nm). The specific enzyme activity is obtained by dividing the activity for the substrate by the protein concentration.

[0069] As used herein, the genus "Bacillus" includes all species within the genus "Bacillus" known to those skilled in the art, including but not limited to B. subtilis, B. licheniformis, B. lentus, B. brevis, B. stearothermophilus, B. alkalophilus, B. amyloliquefaciens, B. clausii, B. halodurans, B. megaterium, B. coagulans, B. circulans, B. gibsonii, and B. thuringiensis. It is recognized that the genus Bacillus continues to undergo taxonomic reorganization. Therefore, this genus is intended to include reclassified species, including but not limited to organisms such as B. stearothermophilus, now called Geobacillus stearothermophilus, or B. polymyxa, now called Geobacillus polymyxa. The production of resistant endospores under stressful environmental conditions is considered a defining characteristic of the Bacillus genus, and this characteristic also applies to recently named species such as Alicyclobacillus, Amphibacillus, Aneurinibacillus, Anoxybacillus, Brevibacillus, Filobacillus, Gracilibacillus, Halobacillus, Paenibacillus, Salibacillus, Thermobacillus, Ureibacillus, and Virgibacillus.

[0070] "B.gibsonii subtilisin" includes any subtilisin obtained from or derived from a B.gibsonii source. In one embodiment, the subtilisin variants provided herein may be derived from B.gibsonii-clade subtilisins such as those described in International Publication 2015 / 089447 and International Publication 2016 / 205755. Other B.gibsonii subtilisins include those described in U.S. Patent Application Publication 20090275493 and its variants, International Publication 2016 / 087403 and its variants, and U.S. Patent 7,449,187 and its variants. In other embodiments, B.gibsonii subtilisin includes a polypeptide having an amino acid sequence with at least 80% sequence identity to SEQ ID NO: 1 or 2.

[0071] The term "vector" refers to a nucleic acid construct used to introduce or transfer nucleic acids into target cells or tissues. Vectors are typically used to introduce foreign DNA into cells or tissues. Vectors include plasmids, cloning vectors, bacteriophages, viruses (e.g., viral vectors), cosmids, expression vectors, shuttle vectors, and the like. Vectors typically include an origin of replication, a multicloning site, and a selection marker. The process of inserting a vector into target cells is typically called transformation. In some embodiments, the present invention includes vectors comprising a DNA sequence encoding a serine protease polypeptide (e.g., a precursor or mature serine protease polypeptide) operably linked to a suitable pro-sequence (e.g., a secretory, signal peptide sequence) that can result in the expression of the DNA sequence in a suitable host, as well as the folding and translocation of the recombinant polypeptide chain.

[0072] As used herein in the context of introducing nucleic acid sequences into cells, the term “introduced” refers to any suitable method for transferring nucleic acid sequences into cells. Such introduction methods include, but are not limited to, protoplast fusion, transfection, transformation, electroporation, conjugation, and transduction. Transformation refers to the genetic modification of a cell resulting from the uptake of genetic material (e.g., DNA), optional genomic integration, and expression.

[0073] The term “expression” refers to the transcription and stable accumulation of sense (mRNA) or antisense RNA derived from the nucleic acid molecules of this disclosure. Expression may also refer to the translation of mRNA into polypeptides. Thus, the term “expression” includes any steps involved in “polypeptide production,” including but not limited to transcription, post-transcriptional modification, translation, post-translational modification, and secretion.

[0074] The terms “expression cassette” or “expression vector” refer to nucleic acid constructs or vectors recombinantly or synthetically produced for the expression of a target nucleic acid (e.g., a foreign nucleic acid or transgene) in target cells. The target nucleic acid typically expresses a target protein. Expression vectors or expression cassettes typically contain a promoter nucleotide sequence that drives or promotes the expression of the foreign nucleic acid. Expression vectors or cassettes also typically contain other specific nucleic acid elements that enable the transcription of a particular nucleic acid in target cells. Recombinant expression cassettes can be incorporated into plasmids, chromosomes, mitochondrial DNA, plastid DNA, viruses, or nucleic acid fragments. Some expression vectors have the ability to incorporate and express heterologous DNA fragments in host cells or the genome of host cells. Many prokaryotic and eukaryotic expression vectors are commercially available. The selection of an appropriate expression vector for the expression of a protein from a nucleic acid sequence incorporated into the expression vector is within the scope of the knowledge of those skilled in the art.

[0075] As used herein, a nucleic acid is “operably ligated” to another nucleic acid sequence when it is placed in a functional relationship with that sequence. For example, a promoter or enhancer is operably ligated to a nucleotide coding sequence if the promoter affects the transcription of the coding sequence. A ribosome binding site may be operably ligated to a coding sequence if it is positioned to facilitate the translation of the coding sequence. Typically, “operably ligated” DNA sequences are contiguous. However, enhancers do not need to be contiguous. Ligation is achieved by ligation at a convenient restriction site. If such a site does not exist, a synthetic oligonucleotide adapter or linker may be used according to conventional practice.

[0076] The term "gene" refers to a polynucleotide (e.g., a DNA segment) that codes for a polypeptide and includes regions before and after the coding region. In some cases, a gene contains intervening sequences (introns) between individual coding segments (exons).

[0077] When used in relation to cells, the term "recombinant" typically indicates that a cell has been modified by the introduction of a foreign nucleic acid sequence, or that a cell has been derived from such a modified cell. For example, a recombinant cell may contain a gene not found in the same form in the native (non-recombinant) form of the cell, or a recombinant cell may contain a modified native gene (found in the cell's native form) that has been reintroduced into the cell. A recombinant cell may contain an endogenous nucleic acid to the cell that has been modified without removing the nucleic acid from the cell. Such modifications include gene substitution, site-directed mutation, and modifications obtained by related techniques known to those skilled in the art. Recombinant DNA techniques include techniques for producing recombinant DNA in vitro, and techniques for transferring recombinant DNA into cells where it can be expressed or proliferated, thereby producing recombinant polypeptides. "Recombination" and "recombining" of polynucleotides or nucleic acids generally refer to assembling or combining two or more nucleic acids or polynucleotide chains or fragments to produce a new polynucleotide or nucleic acid.

[0078] A nucleic acid or polynucleotide is said to “encode” a polypeptide if, in its native state or when manipulated by methods known to those skilled in the art, it can be transcribed and / or translated to produce a polypeptide or a fragment thereof. The antisense strand of such a nucleic acid is also said to encode a sequence.

[0079] The terms "host strain" and "host cell" refer to a host suitable for an expression vector containing the target DNA sequence.

[0080] A “protein” or “polypeptide” comprises a polymer sequence of amino acid residues. The terms “protein” and “polypeptide” are used interchangeably herein. One-letter and three-letter codes for amino acids, as defined in accordance with the IUPAC-IUB Joint Commission on Biochemical Nomenclature (JCBN), are used throughout this disclosure. One letter X refers to any of 20 different amino acids. It is also understood that a polypeptide may be encoded by a sequence of more than one nucleotide due to the degeneracy of genetic coding.

[0081] The term "pro sequence" or "propeptide sequence" refers to the amino acid sequence between the signal peptide sequence and the mature protease sequence necessary for the proper folding and secretion of the protease. These are sometimes called intramolecular chaperones. Cleavage of the pro sequence or propeptide sequence yields a mature, active protease. Bacterial serine proteases are often expressed as proenzymes. Examples of modified propeptides are provided, for example, in International Publication No. 2016 / 205710.

[0082] The terms "signal sequence" and "signal peptide" refer to sequences of amino acid residues that may be involved in the secretion or direct transport of a protein's mature or precursor form. Signal sequences are typically located at the N-terminus of a precursor or mature protein sequence. Signal sequences may be endogenous or exogenous. Signal sequences are usually not present in mature proteins. Signal sequences are typically cleaved from proteins by signal peptidases after the protein has been transported.

[0083] The term “mature” form of a protein, polypeptide, or peptide refers to a functional form of a protein, polypeptide, or peptide that does not have a signal peptide sequence and a propeptide sequence.

[0084] The term "precursor" form of a protein or peptide refers to the mature form of a protein that has a pro-sequence operably linked to the amino or carbonyl terminus of the protein. The precursor may also have a "signal" sequence operably linked to the amino terminus of the pro-sequence. The precursor may also have additional polypeptides involved in post-translational activity (e.g., polypeptides cleaved from the precursor to leave the mature form of the protein or peptide).

[0085] With respect to polypeptides, the term "wild-type" refers to naturally occurring polypeptides that do not contain artificial substitutions, insertions, or deletions at one or more amino acid positions. Similarly, with respect to polynucleotides, the term "wild-type" refers to naturally occurring polynucleotides that do not contain artificial substitutions, insertions, or deletions at one or more nucleotides. However, polynucleotides encoding wild-type polypeptides are not limited to naturally occurring polynucleotides and include any polynucleotides encoding wild-type or parent polypeptides.

[0086] With respect to polypeptides, the term “parent” includes references to naturally occurring or wild-type polypeptides, or naturally occurring polypeptides in which artificial substitutions, insertions, or deletions have been made at one or more amino acid positions. With respect to polypeptides, the term “parent” also includes any polypeptide having protease activity that acts as a starting polypeptide for modifications such as substitution, addition, and / or deletion to produce a variant having one or more modifications compared to the starting polypeptide. That is, the parent polypeptide or reference polypeptide is not limited to naturally occurring wild-type polypeptides, but encompasses any wild-type polypeptide, parent polypeptide, or reference polypeptide. Similarly, with respect to polynucleotides, the term “parent” may refer to naturally occurring polynucleotides, or polynucleotides containing artificial substitutions, insertions, or deletions at one or more nucleotides. With respect to polynucleotides, the term “parent” also includes any polynucleotide encoding a polypeptide having protease activity that acts as a starting polynucleotide for modifications such as substitution, addition, and / or deletion to produce a variant protease having modifications such as substitution, addition, and / or deletion compared to the starting polynucleotide. In other words, the polynucleotide encoding the wild-type polypeptide, parent polypeptide, or reference polypeptide is not limited to naturally occurring polynucleotides, but includes any polynucleotide encoding the wild-type polypeptide, parent polypeptide, or reference polypeptide. In some embodiments, the parent polypeptide includes B. gibsonii subtilisin. In some embodiments, the parent polypeptide includes a polypeptide having the amino acid sequence described in SEQ ID NO: 1.

[0087] The term "naturally occurring" refers to sequences and residues found in nature, for example (e.g., polypeptide sequences and the amino acid or nucleotide sequences and nucleotides contained therein). Conversely, the term "not naturally occurring" includes sequences and residues not found in nature, for example (e.g., polypeptide sequences and the amino acid or nucleotide sequences and nucleic acids contained therein).

[0088] As used herein with respect to amino acid residue locations, "corresponding to," "corresponds to," or "corresponds" refers to an amino acid residue at an enumerated position in a protein or peptide, or an amino acid residue that is similar, homologous, or equivalent to an enumerated residue in a protein or peptide. As used herein, "corresponding region" generally refers to a similar position in the related protein or reference protein.

[0089] The terms “derived from” and “obtained from” refer not only to proteins produced or capable of being produced by strains of the organism in question, but also to proteins encoded by DNA sequences isolated from such strains and produced in host organisms containing such DNA sequences. Additionally, the term refers to proteins encoded by synthetic and / or cDNA-derived DNA sequences that possess the distinctive properties of the protein in question. For example, “Bacillus-derived protease” refers to enzymes with proteolytic activity naturally produced by Bacillus, as well as serine proteases produced by Bacillus sources but produced by other host cells transformed with nucleic acids encoding serine proteases through the use of genetic engineering techniques.

[0090] In the context of two polynucleotide or polypeptide sequences, the term “identical” means the nucleotides or amino acids in two sequences that are identical when aligned to the greatest extent possible, as measured using sequence comparison or analysis algorithms known in the art, as described below.

[0091] The terms "identity %", "identity percentage", or "PID" refer to protein sequence identity. The identity percentage can be determined using standard techniques known in the art. The amino acid identity percentage shared by the sequence of interest can be determined by aligning the sequences to directly compare the sequence information, for example, by using a program such as BLAST, MUSCLE, or CLUSTAL. The BLAST algorithm is described, for example, in Altschul et al., J Mol Biol, 215:403-410 (1990) and Karlin et al., Proc Natl Acad Sci USA, 90:5873-5787 (1993). The percentage (%) amino acid sequence identity value is determined by dividing the number of matching identical residues by the total number of residues in the "reference" sequence, including any gaps created by a program for optimal / maximum alignment. In the BLAST algorithm, the "reference" sequence is called the "query" sequence.

[0092] As used herein, “homologous protein” or “homologous protease” refers to proteins that have clear similarities in their primary, secondary, and / or tertiary structures. Protein homology can refer to the similarity of linear amino acid sequences when proteins are aligned. Homologousity can be determined by amino acid sequence alignment using programs such as BLAST, MUSCLE, or CLUSTAL. Homologous searches of protein sequences can be performed with a threshold of 0.001 (E-value cutoff) using BLASTP and PSI-BLAST from NCBI BLAST. (Altschul et al., “Gapped BLAST and PSI BLAST: a new generation of protein database search programs”, Nucleic Acids Res, Set 1;25(17):3389-402(1997)). The BLAST program uses several search parameters, most of which are set to their default values. The NCBI BLAST algorithm finds the most relevant sequences in terms of biological similarity, but is not recommended for query sequences shorter than 20 residues (Altschul et al., Nucleic Acids Res, 25:3389-3402, 1997 and Schaffer et al., Nucleic Acids Res, 29:2994-3005, 2001). Exemplary default BLAST parameters for nucleic acid sequence searches include: adjacent word threshold = 11; E-value cutoff = 10; scoring matrix = NUC.3.1 (match = 1, mismatch = -3); gap opening = 5; and gap extension = 2. Exemplary default BLAST parameters for amino acid sequence searches include: word size = 3; E-value cutoff = 10; scoring matrix = BLOSUM62; gap opening = 11; and gap extension = 1. This information can be used to group protein sequences and / or construct phylogenetic trees from them.Amino acid sequences can be entered into programs such as Vector NTI Advance suite, and guide trees can be created using the neighbor-joining (NJ) method (Saitou and Nei, Mol Biol Evol, 4:406-425, 1987). Tree construction can be calculated using Kimura's correction for sequence distances, ignoring locations with gaps. Programs such as AlignX can display the calculated distance values ​​in parentheses following the molecule name displayed on the phylogenetic tree.

[0093] Understanding molecular homology can reveal information about the evolutionary history of molecules and their functions. When a newly sequenced protein is homologous to an already characterized protein, it provides a strong indicator of the new protein's biochemical function. Two molecules are said to be homologous if they originate from a common ancestor. Homologous molecules can be classified into two classes: paralogs and orthologues. Paralogs are homologs that exist within a single species. Paralogs often differ in their detailed biochemical functions. Orthologues are homologs that exist within different species and have very similar or identical functions. A protein superfamily is the largest grouping (clade) of proteins from which a common ancestor can be inferred. This common ancestor is usually based on sequence alignment and mechanistic similarity. A superfamily typically includes several protein families that exhibit sequence similarity within the family. The term "protein clan" is commonly used for protease superfamilies based on the MEROPS protease classification system. As used herein, the term “subtilisin” includes any member of the S8 serine protease family as described in MEROPS—The Peptidase Database (Rawlings, ND, et al (2016) Twenty years of the MEROPS database of proteolytic enzymes, their substrates and inhibitors. Nucleic Acids Res 44, D343-D350).

[0094] The CLUSTAL W algorithm is another example of a sequence alignment algorithm (see Thompson et al., Nucleic Acids Res, 22:4673-4680, 1994). Default parameters for the CLUSTAL W algorithm include: Gap opening penalty = 10.0; Gap elongation penalty = 0.05; Protein weight matrix = BLOSUM series; DNA weight matrix = IUB; Delay divergence sequence % = 40; Gap separation distance = 8; DNA transition weight = 0.50; List of hydrophilic residues = GPSNDQEKR; Use negative matrix = OFF; Switch residue specific penalty = ON; Switch hydrophilic penalty = ON; and Switch terminal gap separation penalty = OFF. The CLUSTAL algorithm includes deletions that occur at any end. For example, a mutant of a 500-amino acid polypeptide with a 5-amino acid deletion at any end (or within the polypeptide) would have 99% (495 / 500 identical residues × 100) percent sequence identity with respect to the "reference" polypeptide. Such variants are encompassed by variants that have "at least 99% sequence identity" with respect to the polypeptide.

[0095] Nucleic acids or polynucleotides are “isolated” if they are at least partially or completely separated from other components, including but not limited to other proteins, nucleic acids, or cells. Similarly, polypeptides, proteins, or peptides are “isolated” if they are at least partially or completely separated from other components, including but not limited to other proteins, nucleic acids, or cells. On a molar basis, isolated species are more abundant than other species in the composition. For example, isolated species may comprise at least about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or about 100% (on a molar basis) of all macromolecular species present. Preferably, the species of interest is purified to be essentially homogeneous (i.e., contaminating species cannot be detected in the composition by conventional detection methods). Purity and homogeneity can be determined using many techniques well known in the art, such as agarose or polyacrylamide gel electrophoresis of nucleic acid or protein samples, followed by visualization by staining. If desired, high-resolution techniques, such as high-performance liquid chromatography (HPLC) or similar means, can be used for purifying the materials.

[0096] The term “purified” applied to nucleic acids or polypeptides generally indicates nucleic acids or polypeptides that are essentially free of other components, as determined by analytical techniques well known in the art (e.g., purified polypeptides or polynucleotides form distinct bands in electrophoretic gels, chromatographic eluents, and / or culture media subjected to density gradient centrifugation). For example, a nucleic acid or polypeptide that essentially produces one band on an electrophoretic gel is “purified.” Purified nucleic acids or polypeptides have a purity of at least about 50%, usually at least about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, about 99.5%, about 99.6%, about 99.7%, or about 99.8% or higher (e.g., by weight percentage on a molar basis). In a related sense, a composition is concentrated with respect to molecules if the concentration of molecules increases significantly after the application of purification or concentration techniques. The term "concentrated" refers to compounds, polypeptides, cells, nucleic acids, amino acids, or other specific substances or components present in the composition at a higher relative or absolute concentration than in the starting composition.

[0097] The term "cleaning activity" refers to the cleaning performance achieved by a serine protease polypeptide, variant, or reference subtilisin under the dominant conditions during proteolysis, hydrolysis, washing, or other processes of this disclosure. In some embodiments, the cleaning performance of a serine protease or reference subtilisin may be determined by using a variety of assays for washing one or more enzyme-sensitive stains on an article or surface (e.g., stains resulting from food, grass, blood, ink, milk, oil, and / or egg protein). The cleaning performance of one or more subtilisin variants or reference subtilisins described herein may be determined by subjecting the stains on an article or surface to standard cleaning conditions and evaluating the degree to which the stains are removed using a variety of chromatography, spectrophotometric, or other quantitative methodologies. Exemplary cleaning assays and methods are known in the art and include, but are not limited to, those described in International Publication No. 99 / 34011 and U.S. Patent No. 6,605,458, as well as those included in the examples provided below.

[0098] The terms “effective amount” as used herein for one or more subtilisin variants or reference subtilisins refer to the amount of protease that achieves a desired level of enzymatic activity in a particular washing composition. Such an effective amount is readily verifiable by those skilled in the art and is based on many factors, including the specific protease used, the washing application, the specific composition of the washing composition, and whether the composition needs to be liquid or dry (e.g., granules, tablets, bars).

[0099] Disclosed herein are one or more subtilisin variants useful for cleaning applications and cleaning methods, as well as for various industrial applications. Also disclosed herein are one or more isolated, recombinant, substantially pure, or non-naturally occurring subtilisin variants. In some embodiments, one or more subtilisin variants described herein are useful in cleaning applications and can be incorporated into cleaning compositions useful in methods for cleaning articles or surfaces requiring cleaning.

[0115] This disclosure includes subtilisin variants having one or more modifications to surface-exposed amino acids. Surface modifications in enzyme variants may be useful in detergent compositions because they have a minimum performance index for cleaning performance, enzyme stability in detergent compositions, and enzyme thermal stability, at least one of which is improved from the parent subtilisin enzyme. In some embodiments, the surface modifications alter the hydrophobicity and / or charge of the amino acid at its location. Hydrophobicity can be determined using techniques known in the art, such as those described in White and Wimley (White, SH and Wimley, WC, (1999) Annu. Rev. Biophys. Biomol. Struct. 28:319-65). As used herein, “surface properties” can be used with respect to static charge, as well as properties such as hydrophobicity and hydrophilicity exhibited by the protein surface.

[0116] In further embodiments, one or more subtilisin variants described herein have one or more improved properties compared to a reference subtilisin or a parent subtilisin, the improved properties being selected from improved cleaning performance in detergents, improved stability, and a combination thereof.

[0117] In the context of oxidation, chelating agents, denaturation, surfactants, and thermal and / or pH-stable proteases, the terms “enhanced stability” or “improved stability” refer to proteolytic activity that is more highly retained over time compared to a reference protease, e.g., wild-type protease or parental protease. Autolysis has been identified as one mode of subtilisin activity loss in liquid detergents (Stoner et al., 2004 Protease autolysis in heavy-duty liquid detergent formulations: effects of thermodynamic stabilizers and protease inhibitors, Enzyme and Microbial Technology 34:114-125).

[0118] With respect to protease variants, the terms “thermally stable,” “thermally stable,” and “thermally stable” refer to a protease that retains a greater amount of residual activity compared to the parent protease or reference protease after exposure to altered temperatures over a given period of time under dominant conditions (or “stress conditions”) during proteolysis, hydrolysis, washing, or other processes. Residual activity is the amount of activity remaining after testing compared to the initial activity of the sample and can be reported as a percentage, e.g., % residual activity. “Altered temperature” includes increased or decreased temperatures. In some embodiments, the protease variants provided herein are exposed to a temperature of 40°C to 80°C for a given period of time, for example, at least about 5 minutes, at least about 20 minutes, at least about 60 minutes, about 90 minutes, about 120 minutes, about 180 minutes, about 240 minutes, about 300 minutes, about 360 minutes, about 420 minutes, about 480 minutes, about 540 minutes, about 600 minutes, about 660 minutes, about 720 minutes, about 780 minutes, about After exposure for 840 minutes, approximately 900 minutes, approximately 960 minutes, approximately 1020 minutes, approximately 1080 minutes, approximately 1140 minutes, or approximately 1200 minutes, the proteolytic activity is retained at least approximately 5%, approximately 10%, approximately 20%, approximately 30%, approximately 40%, approximately 50%, approximately 60%, approximately 70%, approximately 80%, approximately 85%, approximately 90%, approximately 92%, approximately 95%, approximately 96%, approximately 97%, approximately 98%, or approximately 99%.

Some such recombinant cells are transformed or transfected with at least one such vector, but other methods are available and known in the art. Such cells are typically called host cells. Some such cells include bacterial cells, including but not limited to Bacillus species cells, e.g., B. subtilis cells. Other embodiments relate to recombinant cells (e.g., recombinant host cells) comprising one or more subtilisins described herein.

[0147] For the expression and production of a target protein (e.g., one or more subtilisin variants described herein) in cells, one or more expression vectors containing one or more copies, possibly multiple copies, of the polynucleotide encoding one or more subtilisin variants described herein are transformed into cells under conditions suitable for the expression of the variants. In some embodiments, the polynucleotide sequence encoding one or more subtilisin variants described herein (and other sequences included in the vector) is incorporated into the host cell genome, while in other embodiments, the plasmid vector containing the polynucleotide sequence encoding one or more subtilisin variants described herein remains in the cell as an autonomous extrachromosomal element. Some embodiments provide both an extrachromosomal nucleic acid element and an input nucleotide sequence that is incorporated into the host cell genome. The vectors described herein are useful for the production of one or more subtilisin variants described herein. In some embodiments, the polynucleotide construct encoding one or more subtilisin variants described herein resides on an integration vector that allows for the integration of the polynucleotide encoding the variants into the host chromosome and optional amplification. Examples of sites for integration are well known to those skilled in the art. In some embodiments, the transcription of polynucleotides encoding one or more subtilisin variants described herein is achieved by a promoter that is the wild-type promoter of the parent subtilisin. In some other embodiments, the promoter is heterogeneous for one or more subtilisin variants described herein but is functional in the host cell.Exemplary promoters for use in bacterial host cells include the amyE, amyQ, amyL, pstS, sacB, pSPAC, pAprE, pVeg, and pHpaII promoters; the B. stearothermophilus maltose amylase gene promoter; the B. amyloliquefaciens (BAN) amylase gene; the B. subtilis alkaline protease gene; the B. clausii alkaline protease gene; the B. pumilus xylosidase gene; the B. thuringiensis cryIIIA gene; and the B. licheniformis α-amylase gene.

[0148] One or more subtilisin variants described herein may be produced in host cells of any suitable microorganism, including bacteria and fungi. In some embodiments, one or more subtilisin variants described herein may be produced in Gram-positive bacteria. In some embodiments, the host cells are Bacillus spp., Streptomyces spp., Escherichia spp., Aspergillus spp., Trichoderma spp., Pseudomonas spp., Corynebacterium spp., Saccharomyces spp., or Pichia spp. In some embodiments, one or more subtilisin variants described herein are produced by Bacillus species host cells.

In some embodiments, B. subtilis host cells are used to produce the mutants described herein. U.S. Patents No. 5,264,366 and No. 4,760,025 (RE 34,606) describe various Bacillus host strains that can be used to produce one or more subtilisin mutants described herein, but other suitable strains may also be used.

[0149] Some bacterial strains that can be used to produce one or more subtilisin variants described herein include non-recombinant (i.e., wild-type) Bacillus species strains, as well as naturally occurring strains and / or recombinant strains. In some embodiments, the host strain is a recombinant strain in which polynucleotides encoding one or more subtilisin variants have been introduced into the host. In some embodiments, the host strain is a B. subtilis host strain, in particular a recombinant B. subtilis host strain. Numerous B. subtilis strains are publicly known, such as 1A6 (ATCC 39085), 168 (1A01), SB19, W23, Ts85, B637, PB1753~PB1758, PB3360, JH642, 1A243 (ATCC 39,087), ATCC 21332, ATCC 6051, MI113, DE100 (ATCC 39,094), GX4931, PBT 110, and PEP 211 (e.g., Hoch et al., Genetics). This includes, but is not limited to, 73:215-228 (1973); see also U.S. Patent No. 4,450,235; U.S. Patent No. 4,302,544; and European Patent No. 0134048. The use of B. subtilis as an expression host cell is well known in the art (see, for example, Palva et al., Gene 19:81-87 (1982); Fahnestock and Fischer, J. Bacteriol., 165:796-804 (1986); and Wang et al., Gene 69:39-47 (1988)).

[0150] In some embodiments, the Bacillus host cell is a Bacillus species containing a mutation or deletion in at least one of the following genes: degU, degS, degR, and degQ. In some embodiments, the mutation is in the degU gene, and in some embodiments, the mutation is degU(Hy)32 (see, for example, Msadek et al., J.Bacteriol. 172:824-834 (1990); and Olmos et al., Mol.Gen.Genet. 253:562-567 (1997)). In some embodiments, the Bacillus host includes mutations or deletions in scoC4 (see, e.g., Caldwell et al., J. Bacteriol. 183:7329-7340 (2001)); spoIIE (see, e.g., Arigoni et al., Mol. Microbiol. 31:1407-1415 (1999)); and / or other genes in oppA or the opp operon (see, e.g., Perego et al., Mol. Microbiol. 5:173-185 (1991)). In fact, any mutation in the opp operon that produces the same phenotype as a mutation in the oppA gene is intended to be used in some embodiments of the modified Bacillus strains described herein. In some embodiments, these mutations occur individually, while in other embodiments, combinations of mutations exist. In some embodiments, the modified Bacillus host cell lines that can be used to produce one or more subtilisin variants described herein are Bacillus host cells that already contain mutations in one or more of the genes described above. Furthermore, Bacillus species host cells containing mutations and / or deletions of endogenous protease genes are used. In some embodiments, the Bacillus host cells contain deletions of the aprE and nprE genes. In other embodiments, the Bacillus species host cells contain deletions of five protease genes, while in other embodiments, the Bacillus species host cells contain deletions of nine protease genes (see, for example, U.S. Patent Application Publication No. 2005 / 0202535).

[0151] Host cells are transformed with one or more nucleic acid sequences encoding one or more subtilisin variants described herein using any preferred method known in the art. Methods for introducing nucleic acids (e.g., DNA) into Bacillus cells or E. coli (Escherichia coli) cells using plasmid DNA constructs or vectors, and methods for transforming such cells with such plasmid DNA constructs or vectors are well known. In some embodiments, the plasmid is subsequently isolated from E. coli cells and transformed into Bacillus cells. However, the use of intervening microorganisms such as E. coli is not essential, and in some embodiments, the DNA construct or vector is introduced directly into the Bacillus host.

[0152] Exemplary methods for introducing one or more nucleic acid sequences described herein into Bacillus cells include, for example, Ferrari et al., "Genetics," in Harwood et al. [ed.], Bacillus, Plenum Publishing Corp. (1989), pp. 57-72; Saunders et al., J. Bacteriol. 157: 718-726 (1984); Hoch et al., J. Bacteriol. 93: 1925-1937 (1967); Mann et al., Current Microbiol. 13: 131-135 (1986); Holubova, Folia Microbiol. 30: 97 (1985); Chang et al., Mol. Gen. Genet. 168: 11-115 (1979); Vorobjeva et al., FEMS This is described in Microbiol. Lett. 7:261-263 (1980); Smith et al., Appl. Env. Microbiol. 51:634 (1986); Fisher et al., Arch. Microbiol. 139:213-217 (1981); and McDonald, J. Gen. Microbiol. 130:203 (1984). In fact, methods such as transformation including protoplast transformation and transfection, transduction, and protoplast fusion are well known and suitable for use herein. Methods known in the art for transforming Bacillus cells include plasmid marker rescue transformation, which involves the uptake of a donor plasmid by competent cells possessing a partially homologous commensal plasmid (see Contente et al., Plasmid 2:555-571 (1979); Haima et al., Mol. Gen. Genet. 223:185-191 (1990); Weinrauch et al., J. Bacteriol. 154:1077-1087 (1983); and Weinrauch et al., J. Bacteriol. 169:1205-1211 (1987)).In this method, the input donor plasmid is recombined with a homologous region of a resident "helper" plasmid in a process that mimics chromosome transformation.

[0153] In addition to commonly used methods, in some embodiments, host cells are directly transformed with a DNA construct or vector containing nucleic acids encoding one or more subtilisin variants described herein (i.e., no intermediate cells are used to amplify the DNA construct or vector before introduction into host cells, or to do so by other means). The introduction of the DNA construct or vector into host cells described herein includes physical and chemical methods known in the art for introducing nucleic acid sequences (e.g., DNA sequences) into host cells without insertion into the host genome. Such methods include, but are not limited to, calcium chloride precipitation, electroporation, naked DNA, and liposomes. In additional embodiments, the DNA construct or vector is co-transformed with a plasmid without insertion into the plasmid. In further embodiments, the selection marker is deleted from the modified Bacillus strain by a method known in the art (see, for example, Stahl et al., J. Bacteriol. 158:411-418 (1984); and Palmeros et al., Gene 247:255-264 (2000)).

[0154] In some embodiments, transformed cells are cultured in a conventional nutrient medium. Preferred specific culture conditions, such as temperature and pH, are known to those skilled in the art and are well documented in the scientific literature. Some embodiments provide a culture (e.g., a cell culture) containing one or more subtilisin variants or nucleic acid sequences described herein.

[0155] In some embodiments, host cells transformed with one or more polynucleotide sequences encoding one or more subtilisin variants described herein are cultured in a suitable nutrient medium under conditions that allow for the expression of the variants, and the resulting variants are then recovered from the culture. In some embodiments, the variants produced by the cells are recovered from the culture medium by conventional procedures including, but not limited to, separation of host cells from the medium by centrifugation or filtration, precipitation of protein components of the supernatant or filtrate with a salt (e.g., ammonium sulfate), and chromatographic purification (e.g., ion exchange, gel filtration, affinity, etc.).

[0156] In some embodiments, one or more subtilisin variants produced by recombinant host cells are secreted into the culture medium. Purification of the variants can be facilitated using nucleic acid sequences encoding purification-promoting domains. Vectors or DNA constructs comprising polynucleotide sequences encoding one or more subtilisin variants described herein may further include nucleic acid sequences encoding purification-promoting domains to facilitate the purification of the variants (see, for example, Kroll et al., DNA Cell Biol. 12:441-53 (1993)). Such purification-promoting domains include, but are not limited to, metal chelate peptides such as the histidine-tryptophan module enabling purification on immobilized metals (Porath, Protein Expr. Purif. 3:263-281

[1992] ), protein A domains enabling purification on immobilized immunoglobulins, and domains used in FLAGS extension / affinity purification systems. Including a cleavable linker sequence, such as factor XA or enterokinase (e.g., Invitrogen, a sequence available from San Diego, California), between the purified domain and the heterologous protein is also used to facilitate purification.

[0157] A wide range of methods can be used to determine the production levels of one or more mature subtilisin variants described herein in host cells. Such methods include, but are not limited to, methods utilizing either protease-specific polyclonal or monoclonal antibodies. Exemplary methods include, but are not limited to, enzyme-linked immunosorbent assays (ELISA), radioimmunoassays (RIA), fluorescence immunoassays (FIA), and fluorescence-activated cell sorting (FACS). These and other assays are well known in the art (see, for example, Maddox et al., J.Exp.Med.158:1211 (1983)).

[0158] Some other embodiments provide methods for constructing or producing one or more mature subtilisin variants described herein. Mature subtilisin variants do not contain signal peptide or propeptide sequences. Some methods involve constructing or producing one or more subtilisin variants described herein in recombinant bacterial host cells, such as Bacillus species cells (e.g., B. subtilis cells). Other embodiments provide methods for producing one or more subtilisin variants described herein, the methods comprising culturing recombinant host cells containing a recombinant expression vector comprising nucleic acid sequences encoding one or more subtilisin variants described herein under conditions that promote the production of the variants. Some such methods further include recovering the variants from the culture.

[0159] Further embodiments include a method for producing one or more subtilisin variants as described herein, comprising: (a) introducing a recombinant expression vector containing a nucleic acid encoding the variant into a population of cells (e.g., bacterial cells such as B. subtilis cells); and (b) culturing the cells in a culture medium under conditions that promote the production of the variant encoded by the expression vector. This includes (c) isolating the mutant from cells or culture medium. Some such methods further include (c) isolating the mutant from cells or culture medium.

[0160] Further embodiments include methods for improving the washing performance or stability of subtilisin, which include modifying the subtilisin to include one or more substitutions or combinations of substitutions, as provided herein.

[0161] Unless otherwise specified, all component or composition levels relate to the activity level of that component or composition, excluding impurities that may be present in commercially available sources, such as residual solvents or by-products. The weight of enzyme components is based on total active protein. All percentages and ratios are calculated on a weight basis unless otherwise specified. All percentages and ratios are calculated based on the total composition unless otherwise specified. The compositions described herein include cleaning compositions, such as detergent compositions. In the example detergent compositions, enzyme levels are expressed in terms of pure enzyme on a weight basis of the total composition, and unless otherwise specified, detergent components are expressed on a weight basis of the total composition.

[0162] In one embodiment, one or more subtilisin variants described herein are useful in cleaning applications including, but not limited to, cleaning tableware or dining tableware, fabrics, medical instruments, and articles having hard surfaces (e.g., hard surfaces of tables, tabletops, walls, furniture, floors, and ceilings). In another embodiment, one or more subtilisin variants described herein are useful in disinfection applications including, but not limited to, disinfection of automatic dishwashers or washing machines.

[0163] Another embodiment relates to a composition comprising one or more subtilisin variants described herein. In some embodiments, the composition is a cleaning composition.

In yet another embodiment, the composition is selected from laundry detergent compositions, automatic dishwashing (ADW) compositions, manual dishwashing detergent compositions, hard surface cleaning compositions, eyeglass cleaning compositions, medical device cleaning compositions, disinfectant (e.g., odor or microorganism) compositions, and personal care cleaning compositions. In yet another embodiment, the composition is a laundry detergent composition, an ADW composition, or a manual dishwashing detergent composition. Further embodiments relate to fabric cleaning compositions, while other embodiments relate to non-fabric cleaning compositions. In some embodiments, the cleaning composition does not contain boron. In other embodiments, the cleaning composition does not contain phosphates. In yet another embodiment, the composition comprises one or more subtilisin variants described herein and one or more excipients, auxiliary substances, and / or additional enzymes.

[0164] Protease stabilizer Peptaldehydes can be used as protease stabilizers in detergent formulations, as previously described (International Publication No. 199813458, International Publication No. 2011036153, U.S. Patent Application Publication No. 20140228274). Examples of peptaldehyde stabilizers are peptaldehyde, ketones, or halomethyl ketones, which may be "N-capped" with, for example, a ureide, carbamate, or urea moiety, or may be "double N-capped" with, for example, a carbonyl, ureide, oxamide, thioureide, dithiooxamide, or thioxamide moiety (European Patent No. 2358857(B1)). The molar ratio of these inhibitors to proteases may be 0.1:1 to 100:1, for example, 0.5:1 to 50:1, 1:1 to 25:1, or 2:1 to 10:1. Other examples of protease stabilizers are benzophenone or anilide benzoate derivatives, which may contain a carboxyl group (U.S. Patent No. 7,968,508). The molar ratio of these stabilizers to protease is preferably in the range of 1:1 to 1000:1, particularly 1:1 to 500:1, especially preferably 1:1 to 100:1, and most especially preferably 1:1 to 20:1.

[0165] Complexing agent system For the purposes of this invention, a "complexing agent" is a compound capable of binding to polyvalent ions such as calcium, magnesium, lead, copper, zinc, cadmium, mercury, manganese, iron, aluminum, and other cationic polyvalent ions to form a water-soluble complex. The complexing agent has a logarithmic stability constant ([logK]) of at least 3 with respect to Ca2+. The stability constant, logK, is measured in a solution with an ionic strength of 0.1 at a temperature of 25°C.

[0166] The composition of the present invention preferably contains 10% to 50% by weight of a complexing agent composition. The complexing agent system comprises one or more complexing agents selected from the group consisting of methylglycine diacetic acid (MGDA), citric acid, glutamic acid-N,N-diacetic acid (GLDA), iminodisuccinic acid (IDS), carboxymethyl inulin, L-aspartic acid N,N-diacetic acid tetrasodium salt (ASDA), and mixtures thereof.

This composition containing a high level of MGDA functions well even in hard water and during long-term and / or high-temperature cycles.

[0168] The complexing agent system of the present invention may further contain citric acid.

[0169] Dispersant polymer The dispersant polymer may be used in any suitable amount of the composition, ranging from about 0.1 to about 20% by weight, preferably 0.2 to about 15% by weight, and more preferably 0.3% by weight.

[0170] The dispersant polymer can suspend calcium or calcium carbonate in an automated dishwashing process.

[0171] The dispersant polymer has calcium binding ability within the range of 30 to 250 mg Ca / g at 25°C, preferably 35 to 200 mg Ca / g, and more preferably 40 to 150 mg Ca / g. To determine whether a polymer is a dispersant polymer in the sense of the present invention, the following calcium binding ability determination is performed according to the instructions below.

[0172] Calcium Binding Capacity Test Method The calcium binding capacity referred to herein is determined by titration using a pH / ion meter such as a Meettler Toledo SevenMulti® benchtop meter and a PerfectION® comb-type Ca combination electrode. To measure the binding capacity, a heating and stirring device suitable for a beaker or turgotometer pot is set to 25°C, and the meter-equipped ion electrode is calibrated according to the manufacturer's instructions. The standard concentration for electrode calibration must be measured at 25°C by bracketing the test concentration. A stock solution of 1000 mg / g Ca is prepared by adding 3.67 g of CaCl2-2H2O to 1 L of deionized water, and then diluted to prepare three 100 mL working solutions containing calcium at concentrations of 100 mg / g, 10 mg / g, and 1 mg / g, respectively. The 100 mg Ca / g working solution is used as the initial concentration during the titration performed at 25°C. The ionic strength of each working solution is adjusted by adding 2.5 g / L of NaCl to each. Heat 100 mL of the 100 mg Ca / g working solution and stir until it reaches 25°C. The initial measurement of calcium ion concentration is performed using an ion electrode when the solution reaches 25°C. Then, gradually add the test polymer to the calcium working solution (in 0.01 g / L increments), stirring for 5 minutes after each increment and then measuring. Stop the titration when the solution reaches 1 mg / g of calcium. Repeat the titration procedure with the remaining two calcium concentrations of working solutions. The binding ability of the test polymer is calculated as a linear gradient of the measured calcium concentration against the grams / L of the added test polymer.

[0173] The dispersant polymer preferably has a negative net charge when dissolved in an aqueous solution having a pH greater than 6.

Nonionic surfactants have also been found to contribute to preventing the redeposition of dirt.

[0207] Preferably, the composition of the present invention comprises a nonionic surfactant or a nonionic surfactant system, more preferably the nonionic surfactant or nonionic surfactant system having a phase inversion temperature of 40 to 70°C, preferably 45 to 65°C, when measured in distilled water at a concentration of 1%. "Nonionic surfactant system" in this specification means a mixture of two or more nonionic surfactants. Nonionic surfactant systems are preferred for use in this specification. They are considered to have improved cleaning and finish characteristics and good stability in the product compared to a single nonionic surfactant.

[0208] The phase inversion temperature is the temperature at which, below which surfactants or mixtures thereof preferentially distribute as oil-expanding micelles into the aqueous phase, and above which, they preferentially distribute as water-expanding inverse micelles into the oily phase. The phase inversion temperature can be visually determined by identifying the temperature at which turbidity occurs.

[0209] The phase inversion temperature of a nonionic surfactant or system can be determined as follows: Prepare a solution containing 1% by weight of the corresponding surfactant or mixture in distilled water. After gently stirring the solution, analyze the phase inversion temperature to ensure that the process occurs at chemical equilibrium. The phase inversion temperature is measured in a thermally stable bath by immersing the solution in a 75 mm sealed glass test tube. Weigh the test tube before and after measuring the phase inversion temperature to ensure there is no leakage. Gradually increase the temperature at a rate of less than 1°C / min until the temperature reaches a few degrees below the predicted phase inversion temperature. The phase inversion temperature is visually determined when the first signs of turbidity appear.

[0210] Suitable nonionic surfactants include: i) ethoxylated nonionic surfactants prepared by reacting a monohydroxyalkanol or alkylphenol having 6 to 20 carbon atoms with ethylene oxide in an amount of at least 12 moles, particularly preferably at least 16 moles, and even more preferably at least 20 moles per mole of alcohol or alkylphenol; and ii) alcohol alkoxylated surfactants having 6 to 20 carbon atoms and at least one ethoxy group and a propoxy group.

[Examples]

[0245] (Example 1) Expression of the BG46 subtilisin mutant The wild-type subtilisin of Bacillus gibsonii Bgi02446 (BG46) is provided in Sequence ID No. 1. In this study, BG46 subtilisin mutants with substitutions S039E, S099R, S126A, D127E, and F128G (Sequence ID No. 2) are used as a starting point for further manipulation of substitution mutants and are referred to as BG46+S039E-S099R-S126A-D127E-F128G. All BG46 subtilis mutants were expressed using a DNA fragment containing, in a sequential order, a 5'AprE flanking region (the B.subtilis rrnIp2 promoter and the manipulated mutants are more fully described in International Publication No. 2020112609 of the patent application) containing a variant of the B.subtilis rrnIp2 promoter sequence (SEQ ID NO: 3), a nucleotide sequence encoding the aprE signal peptide sequence (SEQ ID NO: 4), a nucleotide sequence encoding the B.lentus polypeptide (SEQ ID NO: 5), a sequence corresponding to the gene encoding the mature BG46 subtilis, a BPN' terminator (SEQ ID NO: 6), and a 3'AprE flanking sequence containing a kanamycin resistance gene expression cassette (SEQ ID NO: 7). This DNA fragment was assembled using standard molecular biology techniques. Linear DNA from the expression cassette was used to transform competent B.subtilis cells of appropriate strains.

[0246] The transformation mixture was plated onto LA plates containing 1.6% skim milk and 1.8 ppm kanamycin and incubated overnight at 37°C. Single colonies were harvested and grown in Luria broth at 37°C under antibiotic selection.

[0247] For the protein expression experiment, the transformed cells were grown in a shaking incubator at 32 °C, 300 rpm, and 80% humidity for 3 days in a 96-well microtiter plate (MTP) in a culture medium (a MOPS buffer-based concentrated semi-defined medium containing urea as the main nitrogen source, glucose as the main carbon source, supplemented with 1% soyton for strong cell growth, and including antibiotic selection). After centrifugation and filtration, the clarified culture supernatant containing the protease of interest was used for the assay.

[0248] (Example 2) Assay Protein determination The concentration of the BG46 subtilisin variant in the culture supernatant was determined by UHPLC using a Zorbax 300 SB-C3 column and a linear gradient of 0.1% trifluoroacetic acid (solution A) and 0.07% trifluoroacetic acid (solution B) in acetonitrile and detection at 220 nm. The culture supernatant was diluted with 10 mM NaCl, 0.1 mM CaCl2, 0.005% Tween®-80 and loaded onto the column. The protein concentration of the sample was calculated using a standard curve of the purified parental enzyme.

[0249] Protease activity The protease activity of the BG46 subtilisin variant was tested by measuring the hydrolysis of the AAPF-pNA synthetic peptide substrate.

[0250] For the AAPF assay, the reagent solutions used were as follows: 100 mM Tris pH 8.6, 10 mM CaCl2, 0.005% Tween®-80 in DMSO (Tris / Ca buffer), and 160 mM suc-AAPF-pNA (suc-AAPF-pNA stock solution) (Sigma: S-7388). To prepare the working solution, 1 mL of the suc-AAPF-pNA stock solution was added to 100 mL of the Tris / Ca buffer and mixed. Enzyme samples were added to a microtiter plate (MTP) containing 1 mg / mL of the suc-AAPF-pNA working solution, and the activity was assayed at 405 nm for 3 - 5 minutes using a SpectraMax plate reader in dynamic mode at room temperature (RT). Protease activity was expressed as mOD / min.

[0251] Stability assay in Tris-EDTA The BG46 subtilisin variants described herein were diluted with stress buffer, and the stability of the variants was measured by measuring the proteolytic activity of the variants before and after the heat incubation step using the above AAPF assay. The temperature and duration of the heat incubation step were selected such that the reference protease exhibited approximately 15 - 30% residual activity. Samples were incubated at 60 °C for 5 minutes in a 384-well thermal cycler. Stability was measured under buffer conditions of Tris-EDTA (50 mM Tris pH 9; 5 mM EDTA, 0.005% Tween®-80). The stability results were calculated as the percentage (%) of residual activity for each enzyme sample by taking the ratio of mOD / min for stress conditions to non-stress conditions and multiplying by 100.

[0255] The solid and gel phases can be combined as desired. The spatial arrangement of the gel phase, which is liquid after mixing the components and dimensionally stable within a maximum curing time of 10 minutes, can be predetermined by the spatial arrangement of the solid phase and by commercially available or self-designed molds. A water-soluble package in the form of an open pouch can be produced by deep drawing a PVOH-containing film. The liquid composition can be injected into the aforementioned open cavity to yield a gel phase after curing, and then the solid phase in the form of a free-flowing solid can be injected into a pouch containing polyvinyl alcohol. 1.0 g of the liquid nonionic surfactant Genapol EC 50 can be metered and supplied onto the surface of the resulting fine particles. The proportion of the nonionic surfactant can be significantly increased without altering the other phases. The open pouch can be sealed by applying a second film and sealing it by heat sealing. The prepared detergent portion can be characterized by an attractive aesthetic.

[0256] The dimensions and values ​​disclosed herein should not be understood as being strictly limited to the exact numerical values ​​listed. Instead, unless otherwise indicated, each such dimension is intended to mean both the listed value and the functionally equivalent range encompassing that value. For example, a dimension disclosed as "40 mm" is intended to mean "approximately 40 mm."
