- the bacterial serine proteases have molecular weights in the 20,000 to 45,000 Daltons range. They are inhibited by diisopropylfluorophosphate. They hydrolyze simple terminal esters and are similar in activity to eukaryotic chymotrypsin, also a serine protease.
- subtilisin A sub-group of the serine proteases tentatively designated subtilases has been proposed by Siezen et al. (1991 ), Protein Eng., 4 719-737. They are defined by homology analysis of more than 40 amino acid sequences of serine proteases previously referred to as subtilisin-like proteases. A subtilisin was previously defined as a serine protease produced by Gram-positive bacteria or fungi, and according to Siezen et al.
- subtilisins A wide variety of subtilisins have been identified, and the amino acid sequence of a number of subtilisins have been determined. These include more than six subtilisins from Bacillus strains, namely, subtilisin 168, subtilisin BPN', subtilisin Carlsberg, subtilisin Y, subtilisin amylosacchariticus, and mesentericopeptidase (Kurihara et al.

- subtilisins are well-characterized physically and chemically. In addition to knowledge of the primary structure (amino acid sequence) of these enzymes, over 50 high resolution X-ray structures of subtilisins have been determined which delineate the binding of substrate, transition state, products, at least three different protease inhibitors, and define the structural consequences for natural variation (Kraut (1977) Ann. Rev. Biochem. 46 331-358).

Abstract

Description
TITLE: A STABILIZED LIQUID ENZYME COMPOSITION
FIELD OF THE INVENTION
The present invention relates to a liquid composition, comprising an enzyme and an enzyme stabilizer. The invention further relates to the use of said liquid composition.
BACKGROUND OF THE INVENTION
Storage stability problems are well known with liquids containing enzyme(s). Especially in enzyme-containing liquid detergents a major problem, in particular if the detergent contains protease, is that of ensuring enzyme activity over time. The prior art has dealt extensively with improving the storage stability, for example by adding a protease inhibitor.
Boric acid and boronic acids are known to reversibly inhibit proteolytic enzymes. A discussion of the inhibition of one serine protease, subtilisin, by boronic acid is provided in Molecular & Cellular Biochemistry 51 , 1983, pp. 5-32. Boronic acids have very different capacities as subtilisin inhibitors. Boronic acids containing only alkyl groups such as methyl, butyl or 2-cyclohexylethyl are poor inhibitors with methylbo- ronic acid as the poorest inhibitor, whereas boronic acids bearing aromatic groups such as phenyl, 4-methoxyphenyl or 3,5-dichlorophenyl are good inhibitors with 3,5- dichlorophenylboronic acid as a particularly effective one (see Keller et al, Biochem. Biophys. Res. Com. 176, 1991 , pp. 401-405). It is also claimed that aryl boronic acids which have a substitution at the 3-position relative to boron are unexpectedly good reversible protease inhibitors. Especially, acetamidophenyl boronic acid is claimed to be a superior inhibitor of proteolytic enzymes (see WO 92/19707). In WO 96/41859 substituted phenyl boronic acids are disclosed as suitable enzyme stabilizers. It has been found that borates are reprotoxic in animals and therefore there is a demand to find alternatives which can be used to stabilize the enzymes in liquid compositions. In a particular embodiment of the present invention the liquid composition does not comprise borate or boric acid. In EP 0 378 261 B1 an enzyme stabilization system comprising carboxylic acids for aqueous liquid detergent compositions is disclosed.
SUMMARY OF THE INVENTION
One object of the present invention is to provide a stable liquid composition.
It has surprisingly been found that aryl carboxylic acids have extraordinary good capacities as enzyme stabilizers in liquids, especially of the following formula:
or a salt hereof, wherein R1 is selected from the group consisting of CO, C1 , C2, C3, C4, C5 alkyl, substituted C1 , C2, C3, C4, C5 alkyl, C1 , C2, C3, C4, C5 alkenyl and substituted C1 , C2, C3, C4, C5, alkenyl and R2, R3, R4, R5 and Re is selected from the group consisting of hydrogen, C1 , C2, C3, C4, C5, C6 alkyl, substituted C1 , C2, C3, C4, C5, C6 alkyl, aryl, sub- stituted aryl, hydroxyl, hydroxyl derivative, amine, C1 , C2, C3, C4, C5, C6 alkylated amine, amine derivative, halogen, nitro, thiol, thiol derivative, aldehyde, acid, acid salt, ester, sulfonate or phosphonate.
The present invention provides thus in a first aspect a liquid composition comprising an enzyme and an enzyme stabilizer of the following formula:

Mixtures of enzymes from the same class (e.g. proteases) are also included.

In a particular embodiment a liquid composition comprising two or more enzymes in which the first enzyme is a protease and the second enzyme is selected from the group consisting of amylases, lipases, cellulases, lyases and oxidoreductases is preferred. In a more particular embodiment the second enzyme is a lipase.
It is to be understood that enzyme variants (produced, for example, by recombinant techniques) are included within the meaning of the term "enzyme". Examples of such enzyme variants are disclosed, e.g. in EP 251 ,446 (Genencor), WO 91/00345 (Novozymes),
EP 525,610 (Solvay) and WO 94/02618 (Gist-Brocades NV).
Enzymes can be classified on the basis of the handbook Enzyme Nomenclature from NC-
IUBMB, 1992), see also the ENZYME site at the internet:
ENZYME is a repository of information relative to the nomenclature of enzymes. It is primarily based on the recommendations of the Nomenclature Committee of the International Union of
Biochemistry and Molecular Biology (IUB-MB), Academic Press, Inc., 1992, and it describes each type of characterized enzyme for which an EC (Enzyme Commission) number has been provided (Bairoch A. The ENZYME database, 2000, Nucleic Acids Res 28:304-305). This IUB-MB Enzyme nomenclature is based on their substrate specificity and occasionally on their molecular mechanism; such a classification does not reflect the structural features of these enzymes.
Another classification of certain glycoside hydrolase enzymes, such as endoglucanase, xy- lanase, galactanase, mannanase, dextranase and alpha-galactosidase, in families based on amino acid sequence similarities has been proposed a few years ago. They currently fall into
90 different families: See the CAZy (ModO) internet site (Coutinho, P.M. & Henrissat, B.

The liquid composition preferably comprises a protease, such as a serine protease. Proteases: Suitable proteases include those of animal, vegetable or microbial origin. Microbial origin is preferred. Chemically or genetically modified mutants are included. The protease may be a serine protease, preferably an alkaline microbial protease or a trypsin-like protease. Examples of al-kaline proteases are subtilisins, especially those derived from Bacillus, e.g., subtilisin Novo, subtilisin Carlsberg, subtilisin 309, subtilisin 147 and subtilisin 168 (described in WO 89/06279). Examples of trypsin-like proteases are tryp-sin (e.g. of porcine or bovine origin) and the Fusarium pro-tease described in WO 89/06270. In a particular embodiment of the present invention the protease is a serine protease. Serine proteases or serine endopeptidases (newer name) are a class of peptidases which are characterised by the presence of a serine residue in the active center of the enzyme. Serine proteases: A serine protease is an enzyme which catalyzes the hydrolysis of peptide bonds, and in which there is an essential serine residue at the active site (White, Handler and Smith, 1973 "Principles of Biochemistry," Fifth Edition, McGraw-Hill Book Company, NY, pp. 271-272). The bacterial serine proteases have molecular weights in the 20,000 to 45,000 Daltons range. They are inhibited by diisopropylfluorophosphate. They hydrolyze simple terminal esters and are similar in activity to eukaryotic chymotrypsin, also a serine protease. A more narrow term, alkaline protease, covering a sub group, reflects the high pH optimum of some of the serine proteases, from pH 9.0 to 1 1.0 (for review, see Priest (1977) Bacteriological Rev. 41 71 1-753). Subtilases: A sub-group of the serine proteases tentatively designated subtilases has been proposed by Siezen et al. (1991 ), Protein Eng., 4 719-737. They are defined by homology analysis of more than 40 amino acid sequences of serine proteases previously referred to as subtilisin-like proteases. A subtilisin was previously defined as a serine protease produced by Gram-positive bacteria or fungi, and according to Siezen et al. now is a subgroup of the subtilases. A wide variety of subtilisins have been identified, and the amino acid sequence of a number of subtilisins have been determined. These include more than six subtilisins from Bacillus strains, namely, subtilisin 168, subtilisin BPN', subtilisin Carlsberg, subtilisin Y, subtilisin amylosacchariticus, and mesentericopeptidase (Kurihara et al. (1972) J. Biol. Chem. 247 5629-5631 ; Wells et al. (1983) Nucleic Acids Res. 11 791 1-7925; Stahl and Ferrari (1984) J. Bacteriol. 159 81 1-819, Jacobs et al. (1985) Nucl. Acids Res. 13 8913-8926; Nedkov et al. (1985) Biol. Chem. Hoppe-Seyler 366 421-430, Svendsen et al. (1986) FEBS Lett. 196 228-232), one subtilisin from an actinomycetales, thermitase from
Thermoactinomyces vulgaris (Meloun et al. (1985) FEBS Lett. 198 195-200), and one fungal subtilisin, proteinase K from Tritirachium album (Jany and Mayer (1985) Biol.Chem. Hoppe- Seyler 366 584-492). for further reference Table I from Siezen et al. has been reproduced below. Subtilisins are well-characterized physically and chemically. In addition to knowledge of the primary structure (amino acid sequence) of these enzymes, over 50 high resolution X-ray structures of subtilisins have been determined which delineate the binding of substrate, transition state, products, at least three different protease inhibitors, and define the structural consequences for natural variation (Kraut (1977) Ann. Rev. Biochem. 46 331-358). One subgroup of the subtilases, I-S1 , comprises the "classical" subtilisins, such as subtilisin 168, subtilisin BPN', subtilisin Carlsberg (ALCALASE®, Novozymes A/S), and subtilisin DY. A further subgroup of the subtilases I-S2, is recognised by Siezen et al. (supra). Sub-group I- S2 proteases are described as highly alkaline subtilisins and comprise enzymes such as subtilisin PB92 (MAXACAL®, Gist-Brocades NV), subtilisin 309 (SAVINASE®, Novozymes A/S), subtilisin 147 (ESPERASE®, Novozymes A/S), and alkaline elastase YaB.
Random and site-directed mutations of the subtilase gene have both arisen from knowledge of the physical and chemical properties of the enzyme and contributed information relating to subtilase's catalytic activity, substrate specificity, tertiary structure, etc. (Wells et al. (1987) Proc. Natl. Acad. Sci. U.S.A. 84; 1219-1223; Wells et al. (1986) Phil. Trans. R. Soc. Lond.A. 317 415-423; Hwang and Warshel (1987) Biochem. 26 2669-2673; Rao et al., (1987) Nature 328 551-554.
More recent publications covering this area are Carter et al. (1989) Proteins 6 240-248 relating to design of variants that cleave a specific target sequence in a substrate (positions 24 and 64); Graycar et al. (1992) Annals of the New York Academy of Sciences 672 71-79 discussing a number of previously published results; and Takagi (1993) Int. J. Biochem. 25 307-312 also reviewing previous results.
