Description: Title: A polypeptide-polymer conjugate FIELD OF THE INVENTION The present invention relates to a polypeptide-polymer conjugate wherein the polymer is a graft, block, alternate, or random co-polymer coupled to the surface of the polypeptide. The invention also relates to industrial compositions and products comprising a conjugate of the invention, the use of a polypeptide-polymer conjugate of the invention for reducing the allergenicity of industrial compositions and products, and finally a method for reducing the allergenicity of polypeptides. BACKGROUND OF THE INVENTION For both medical and industrial applications the use of po- lypeptides, including enzymes, are well-known m the art. As polypeptides may potentially cause an undesired immune response - dependent on the way of challenge - typically an IgG and/or IgE response, techniques for reducing it have been developed during the last three decades. One technique is the coupling technique where a number of polymeric molecules are coupled to the polypeptide in question. When using this technique the immune system have difficulties recognizing the epitopes (on the polypeptide' s surface) responsible for the formation of antibodies, thereby reducing the immune response. For polypeptides introduced directly into the circulatory system of the human body to give a particular physiological effect (i.e. pharmaceuticals) the typical potential immune response is an IgG and/or IgM response, while polypeptides which are inhaled through the respiratory system (i.e. industrial polypeptide) potentially may cause an IgE response (i.e. allergic response) . One of the theories explaining the reduced immune response is that the polymeric molecule (s) shield (s) epitope(s) on the surface of the polypeptide responsible for the immune response leading to antibody formation. Another theory or at least a partial factor is that the heavier the conjugate is the more reduced immune response is obtained. Typically the polymers used for coupling to polypeptide to form conjugates are homopolymers, i . e . consisting of one repeating unit, e.g., ethylene oxide (EO) , especially polyethylene glycol (PEG) , or propylene oxide (PO) , especially polypropylene glycol (PPG) . Sacchareides, such as dextran have also been used. US patent no. 4,179,337 concerns non-immunogenic polypeptides, such as enzymes and peptide hormones coupled to polyethylene glycol (PEG) or polypropylene glycol (PPG) . WO 96/17929 (Novo Nordisk A/S) concerns modified polypeptide conjugates coupled to polymeric molecules, in particular polyethylene glycol (PEG) . SUMMARY OF THE INVENTION The present invention relates to a polypeptide-polymer conjugate suitable for industrial applications and incorporation as active ingredients in industrial products. The present inventors have found that when coupling graft, block, alternate, or random co-polymers with the general formula : EO x PO y (I) wherein x=l-99%, y=l-99%, and x+y=100% covalently to a parent polypeptide, used for industrial application, the respiratory allergenicity is reduced when compared to the parent enzyme and even when compared to a corresponding conjugate coupled with PEG or other homopolymers. In a second aspect the invention relates to compositions for use in industrial products comprising a conjugate of the invention. In a third aspect the invention relates to a method for reducing the allergenicity of polypeptides. Industrial polypeptides Polypeptides used for industrial applications often have an enzymatic and/or anti-microbial activity. Industrial polypeptides are (in contrast to pharmaceutical polypeptides) not intended to be introduced into the circulatory system of the body. Therefore, it is not very likely that industrial polypeptides, such as enzymes, used as active ingredients in industrial compositions and/or products (defined below) , such as detergents, such as laundry and dish washing detergens, food or feed addivites, including additives for bread making, composition for treating textiles, and personal care products, including cosmetics, come into direct contact with the circulatory system of the body of humans or animals, as such polypeptides (or products comprising such polypeptides) are not injected (or the like) into the bloodstream. Thus, in the case of the industrial polypeptide the poten- tial risk is respiratory allergy (i.e. IgE response) as a consequence of inhalation of polypeptides through the respiratory passage . In the context of the present invention "industrial polypeptides" are defined as polypeptides, including peptides, proteins and/or enzymes, which are not intended to be introduced into the circulatory system of the body of humans and/or animals. Examples of such polypeptide include polypeptides with enzymatic activity as defined below. The invention also relates to industrial compositions and products having reduced respiratory allergenicity. Furthermore, the invention relates to the use of a polypeptide-polymer conjugate of the invention for reducing the respiratory allergenicity of industrial composition and products . Finally the invention relates to a method for reducing the allergenicity of polypeptides, in particular enzymes, by coupling one or more a graft, block, alternate, or random copolymer to a parent unmodified polypeptide. BRIEF DESCRIPTION OF THE DRAWINGS The figure shows the IgE response in Brown Norway rats sera to modified and unmodified enzymes. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a polypeptide-polymer conjugate suitable for industrial applications and incorporation as active ingredients in industrial products. Conjugates of the invention have reduced respiratory allergenicity. The term "polypeptide-polymer conjugate" means in the context of the present invention a polypeptide with one or more polymers covalently coupled thereto. The term "reduced allergenicity" means in the context of the present invention that the amount of produced IgE (in humans, and molecules with comparable effects in specific animals), which can lead to an allergic state, is decreased when inhaling a modified polypeptide of the invention in comparison to the corresponding parent polypeptide. The term "respiratory allergenicity" may be used instead. The present inventors have found that when a parent unmodified polypeptide is coupled to graft, block, alternate, or random co-polymers the potential allergenic response caused by inhalation of the polypeptide is reduced in comparison to a corresponding parent unmodified polypeptide and even in comparison to a corresponding conjugate wherein a corresponding number of homopolymers, such as PEG, have been coupled to the corresponding parent polypeptide. It is well known, that a polymer can adopt different conformation/morphologies depending mainly, but not only on its molecular architecture, the solvent (here water) , the temperature, and the concentration (S. Fδrster and M. Antonietti, Adv. Mater, 1998, 10, No.3, pp 195-217). Those conformation/morphologies include micelles of various shapes, lamellae, ordered cylinders, or bicontinous structures. The molecular conformation of co-polymers in aqueaous media like a solvated random coil, an extended coil, a rod-like polymer, a hypercoil, and a vesicle are well known (Water soluble polymers, M. J. Comstock Ed., ACS Symposium Series, 1991). Thus, without being limited to any theory it is believed that a graft, block, alternate, or random co-polymer linked to the polypeptide surface adopts a conformation m water which yields to a better shielding of the surface as does a more hydrophilic homopolymer. Also synergistic effects due to the formation of supramolecular structures may reduce the accessibility of the polypeptide surface. Furthermore, an increased repulsion of the more lipophilic copolymer (in comparison to a PEG homopolymer) with the antibody might play a role. Further, the more rigid structure (compared to homopolmers) of graft, block, alternate, or random co-polymer may make it more difficult for the antibody to "find its way" (through the more πdgid polymers and the adopted conformation) to the epitope on the polypeptide surface responsible for the IgE formation which results in an allergic response. The hydrophobicity of the polymer is also believed to have an influence on the potential allergenicity of a polypeptide- polymer conjugate. Therefore, the more hydrophibic the polymer is the better does it shield the polypeptide. By a proper choice of polymer and molecular architecture optimal coverage with respect shielding epitopes on the surface of the polypeptide can be obtained. Furthermore, by adjusting the properties of the attached polymers, optimized properties for different formulations, e.g. m fats or creams, can be obtained. In the first aspect the invention relates to a polypeptide- polymer conjugate having coupled one or more polymers covalently to the parent polypeptide, wherein the polymer is characterized by the general formula: EO x PO y (I) wherein x=l-99%, y=l-99%, and x+y=100%. "EO" means ethylene oxide and "PO" means propylene oxide . The molecular weight of the polymer typically lies in the range from 100 Da to 100,000 Da, preferably 100 to 50,000 Da, especially 100 to 10,000 Da. In a preferred embodiment the polymer (s) comprise ethylene oxide units (EO) and propylene oxide units (PO) in a ration in the range from 10:90 or 20:80 or 30:70, 40:60, 50:50, 60:40, 70:30, 80:20 or 90:10. Assessment of allergenicity Allergenicity may be assessed on the basis of inhalation tests, comparing the effect of intratracheally (into the trachea) administrated parent polypeptide with the corresponding modified polypeptide according to the invention. A number of in vivo animal models exist for assessment of the allergenicity of polypeptide. Some of these models give a suitable basis for hazard assessment in man. Suitable models include a guinea pig model and a mouse model. These models seek to identify respiratory allergens as a function of elicitation reactions induced in previously sensitised animals. According to these models the alleged allergens are introduced intratracheally into the animals. A suitable strain of guinea pigs, the Dunkin Hartley strain, do not as humans, produce IgE antibodies in connection with the allergic response. However, they produce another type of antibody the IgGlA and IgGlB (see e.g. Prentø, ATLA, 19, p. 8-14, 1991) , which are responsible for their allergenic response to inhaled polypeptides including enzymes. Therefore, when using the Dunkin Hartley animal model, the relative amount of IgGlA and IgGlB is a measure of the allergenicity level. A rat strain suitable for intratracheal exposure to polypeptides, such as enzymes, is the Brown Norway strain. Brown Norway rats produce IgE as the allergic response. More details on assessing respiratory allergens in guinea pigs and mice is described by Kimber et al., (1996), Fundamental and Applied Toxicology, 33, p. 1-10. Other animals such as e.g. rabbits may also be used for comparable studies. The polymeric molecule The polymer coupled to the polypeptide is a graft, block, alternate, or random co-polymer having the general formula: EO x PO y (I) wherein x=l-99%, y=l-99%, and x+y=100%. The polymer is preferably characterized by the general formula: (I) wherein x=10-90%, y=10-90%, and x+y=100%. In a preferred embodiment of the invention the polymer consists of ethylene oxide units and propylene oxide units in a ration (EO unit: PO unit) of 10:90, 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, 80:20, and 90:10. In a preferred embodiment said polymer has a molecule weight from 100 to 100,000 Da, in particular 100 to 50,000 Da, especially 100 to 10,000 Da. In a more preferred embodiment said polymer has a molecular weight from 100 to 12,000 Da, more preferred from 300 to 3,000 Da. In an embodiment of the invention invention the polymer is a diblock, triblock, multiblock polymer. The general formula (I) should be interpreted as comprising polymers, wherein the EO units and PO units are placed independently. Examples of specific block polymers which may be used to couple to the surface of the polypeptide are: poly (propylene glycol) -block-poly (ethyleneglycol) -block-poly (propylene glycol) ; poly (ethylene glycol) -block-poly (propylene glycol) - block-poly (ethylene glycol); poly (propylene glycol) -block- poly (ethylene glycol) -block-poly (propylene glycol)mono butyl ether; poly (ethylene glycol) -block-poly (propylene glycol) -block- poly (ethylene glycol)mono butyl ether; poly (propylene glycol) - block-poly (ethylene glycol) -block-poly (propylene glycol)mono methyl ether; poly (ethylene glycol) -block-poly (propylene glycol) -block-poly (ethylene glycol)mono methyl ether. Preferred block polymers are block polymers having the general formula: H (-OCH 2 CH 2 -) x [-OCH (CH 3 ) CH 2 -] y (-OCH 2 CH 2 -) z OH, having the average molecule weight (M n ) of 1,100 and the ethylene glycol content of 10 wt%, M n = 1,900 and 50 wt%, M n = 2,000 and 10 wt%, M n = 2,800 and 10 wt%, M n =2,800 and 15 wt%,M n = 2,900 and 40 wt%, M n = 4,400 and 30 wt%, M n = 5,800 and 30 wt%, M n = 8,400 and 80 wt%. Other preferred block polymers are block polymers having the general formula: H [-OCH (CH 3 ) CH 2 -] x (-OCH 2 CH 2 -) y [-OCH (CH 3 ) CH 2 -] z OH, having the average molecule weight (M n ) of 2,000 and the ethylene glycol content of 50 wt%, M r = 2,700 and 40 wt%, and M n = 3,300 and 10 wt%. Examples of specific block polymers are p7120: Pluronics, commercial available from BASF (Germany) , Tergitol commercial available from Union Carbide (USA) , Synperonic coomercial available from Fluka (Switzerland) . Examples of specific co-polymers which may be used to couple to the surface of the polypeptide are: poly (ethylene glycol-co- propylene glycol), especially poly (ethylene glycol-co-propylene glycol) having an an average molecule weight M n of 2,500 and 75 wt% ethylene glycol and an average molecule weight M n of 12,000 and 75 wt% ethylene glycol; poly (ethylene glycol-co-propylene glycol) mono butyl ether, especially poly (ehtylene glycol-co- propylene glycol) monobutyl ether having an M n of 970 and 50 wt% ethylene glycol, an M n of 1,700 and 50 wt% ethylene glycol and an M r of 3,900 and 50 wt% ehtylene glycol; poly (ethylene glycol-co-propylene glycol) mono methyl ether. Preferred polymers are non-toxic polymers composed of e.g. PEG and PPG co-polymers. Polymers requiring a relatively simple chemistry for its covalently coupling to attachment groups on the enzyme's surface are preferred. The graft, block, alternate or radom co-polymers may be star-shaped or branched. Preparation of suitable polymers Polymers to be atteched to the surface of the parent polypeptide may be prepared using standard techniques known in the art. Further, various polymers is commercially available from companies such as BASF (Germany) , Union Carbide (USA) , Aldrich etc. Activation of polymers If the polymer to be conjugated with the polypeptide in question is not active it must be activated by the use of a suitable technique. It is also contemplated according to the in- vention to couple the block or co- polymer to the polypeptide through a linker. Suitable linkers are well-known to the skilled person. Methods and chemistry for activation of polymeric molecules as well as for conjugation of polypeptides are intensively described in the literature. Commonly used methods for activation of insoluble polymers include activation of functional groups with cyanogen bromide, periodate, glutaraldehyde, biepoxides, epichlorohydrin, divinylsulfone, carbodiimide, sulfonyl halides, trichlorotri- azine etc. (see R.F. Taylor, (1991), "Protein immobilisation. Fundamental and applications", Marcel Dekker, N.Y.; S.S. Wong, (1992), "Chemistry of Protein Conjugation and Crosslinking", CRC Press, Boca Raton; G.T. Hermanson et al., (1993), "Immobilized Affinity Ligand Techniques", Academic Press, N.Y.). Some of the methods concern activation of insoluble polymers but are also applicable to activation of soluble polymers e.g. periodate, trichlorotriazine, sulfonylhalides, divinylsulfone, carbodiimide etc. The functional groups being amino, hydroxyl, thiol, carboxyl, aldehyde or sulfydryl on the polymer and the chosen attachment group on the protein must be considered in choosing the activation and conjugation chemistry which normally consist of i) activation of polymer, ii) conjugation, and iii) blocking of residual active groups. In the following a number of suitable polymer activation methods will be described shortly. However, it is to be understood that also other methods may be used. Coupling polymeric molecules to the free acid groups of polypeptides may be performed with the aid of diimide and for e- xample amino-PEG or hydrazino-PEG (Pollak et al., (1976), J. Am. Chem. Soc, 98, 289-291) or diazoacetate/amide (Wong et al . , (1992), "Chemistry of Protein Conjugation and Crosslinking", CRC Press ) . Coupling polymeric molecules to hydroxy groups are generally very difficult as it must be performed in water. Usually hydrolysis predominates over reaction with hydroxyl groups. Coupling polymeric molecules to free sulfhydryl groups can be reached with special groups like maleimido or the ortho- pyridyl disulfide. Also vinylsulfone (US patent no. 5,414,135, (1995), Snow et al.) has a preference for sulfhydryl groups but is not as selective as the other mentioned. Accessible Arginine residues in the polypeptide chain may be targeted by groups comprising two vicinal carbonyl groups. Techniques involving coupling electrophilically activated PEGs to the amino groups of Lysines may also be useful. Many of the usual leaving groups for alcohols give rise to an amine linkage. For instance, alkyl sulfonates, such as tresylates (Nilsson et al., (1984), Methods in Enzymology vol. 104, Jacoby, W. B., Ed., Academic Press: Orlando, p. 56-66; Nilsson et al., (1987), Methods in Enzymology vol. 135; Mosbach, K. , Ed.; Academic Press: Orlando, pp. 65-79; Scouten et al., (1987), Methods in Enzymology vol. 135, Mosbach, K. , Ed., Academic Press: Orlando, 1987; pp 79-84; Crossland et al . , (1971), J. Amr. Chem. Soc. 1971, 93, pp. 4217-4219), mesylates (Harris, (1985), supra; Harris et al . , (1984), J. Polym. Sci. Polym. Chem. Ed. 22, pp 341-352), aryl sulfonates like tosylates, and para-nitrobenzene sulfonates can be used. Organic sulfonyl chlorides, e.g. Tresyl chloride, effectively converts hydroxy groups in a number of polymers, e.g. PEG, into good leaving groups (sulfonates) that, when reacted with nucleophiles like amino groups in polypeptides allow stable linkages to be formed between polymer and polypeptide. In addition to high conjugation yields, the reaction conditions are in general mild (neutral or slightly alkaline pH, to avoid denaturation and little or no disruption of activity) , and satisfy the non-destructive requirements to the polypeptide. Tosylate is more reactive than the mesylate but also more un- stable decomposing into PEG, dioxane, and sulfonic acid (Zalipsky, (1995), Bioconjugate Chem., 6, 150-165). Epoxides may also been used for creating amine bonds but are much less reactive than the above mentioned groups. Converting PEG into a chloroformate with phosgene gives rise to carbamate linkages to Lysines. This theme can be played in many variants substituting the chlorine with N-hydroxy succinimide (US patent no. 5,122,614, (1992); Zalipsky et al., (1992), Biotechnol. Appl. Biochem. , 15, p. 100-114; Monfardini et al., (1995), Bioconjugate Chem., 6, 62-69, with imidazole (Allen et al . , (1991), Carbohydr. Res., 213, pp 309-319), with para-nitrophenol, DMAP (EP 632 082 Al, (1993), Looze, Y.) etc. The derivatives are usually made by reacting the chloroformate with the desired leaving group. All these groups give rise to carbamate linkages to the peptide. Furthermore, isocyanates and isothiocyanates may be employed yielding ureas and thioureas, respectively. Amides may be obtained from PEG acids using the same leaving groups as mentioned above and cyclic imid thrones (US patent no. 5,349,001, (1994), Greenwald et al . ) . The reactivity of these compounds are very high but may make the hydrolysis to fast. PEG succinate made from reaction with succinic anhydride can also be used. The hereby comprised ester group make the conjugate much more susceptible to hydrolysis (US patent no. 5,122,614, (1992), Zalipsky). This group may be activated with N-hydroxy succinimide. Furthermore, a special linker can be introduced. The oldest being cyanuric chloride (Abuchowski et al., (1977), J. Biol. Chem., 252, 3578-3581; US patent no. 4,179,337, (1979), Davis et al.; Shafer et al., (1986), J. Polym. Sci. Polym. Chem. Ed., 24, 375-378. Coupling of PEG to an aromatic amine followed by diazotation yields a very reactive diazonium salt which in situ can be reacted with a peptide. An amide linkage may also be obtained by reacting an azlactone derivative of PEG (US patent no. 5,321,095, (1994), Greenwald, R. B.) thus introducing an additional amide linkage. As some peptides do not comprise many Lysines it may be advantageous to attach more than one PEG to the same Lysine. This can be done e.g. by the use of 1, 3-diamino-2-propanol . PEGs may also be attached to the amino-groups of the enzyme with carbamate linkages (WO 95/11924, Greenwald et al.). Lysine residues may also be used as the backbone. Position of the coupled block or co-polymer (s) Virtually all ionized groups, such as the amino group of Lysine residues, are on the surface of the polypeptide molecule (see for instance Thomas E. Creighton, (1993), "Proteins", W.H. Freeman and Company, New York) . Therefore, the number of readily accessible attachment groups (i.e. amino groups) on the poly- peptide' s surface equals the number of Lysine residues in the primary structure of the polypeptide plus the N-terminus amino group. According to the invention from 1 to 100 polymers, preferably 4 to 50 polymeric molecules, 5 to 35 polymers are coupled to the parent polypeptide in question. The parent polypeptide The modified polypeptides of the invention may be prepared on the basis of parent polypeptides, typically having a molecular weight in the range from 1 to 100 kDa, preferably from 15 to 60 kDa, using any suitable technique known in the art. The term "parent" polypeptide is intended to indicate any uncoupled polypeptide (i.e. a polypeptide to be modified). The polypeptide may preferably be of microbial origin, such as bacterial, filamentous fungus or yeast origin. The parent polypeptide may be a naturally-occurring (or wild- type) polypeptide or may be a variant thereof. Preferred polypeptides are enzymes and polypeptides with anti-microbial activity. In a preferred embodiment the enzyme is an enzyme suitable for skin care compositions and products having a substantially enzymatic activity in the pH range used in the skin care product. When choosing a parent polypeptide it is advantageous to use a polypeptide with the a high number of attachment groups. Further, in a preferred embodiment of the invention the block or co-polymers are spread broadly over the surface of the parent polypeptide. For enzymes it is preferred that no block or co- polymers are coupled in the area close to the active site. In the present context "spread broadly" means positioned so that the polymeric molecules coupled to the attachment groups of the polypeptide shields different parts of the polypeptide surface, preferable the whole or close to the whole surface area to make sure that the relevant epitope (s) being recognisable are shielded and hereby not recognised by the immune system' s antibodies. It is believed that the surface area of interaction between the polypeptide and an antibody lies in the range about 500 A 2 (26 x 19A) (see Sheriff et al . (1987), Proc. Natl. Acad. Sci. USA, Vol. 84, p. 8075). For enzymes it is preferred, to ensure a minimal loss of enzymatic activity, not to couple polymers in a close distance of the active site. Generally seen it is preferred that no polymers are attached within 5 A, preferred 10 A from the active site . Further, polypeptides having coupled polymers at known epitope recognisable by the immune system or close to said epitope are also considered advantageous according to the invention. If the position of the epitope (s) is (are) unknown it is advantageous to coupled as many polymers to the attachment groups available on the surface of the polypeptide. It is preferred that said attachment groups are spread broadly over the surface of the polypeptide in a suitable distance from the active site. Parent polypeptides fulfilling the above claims to the distribution of coupled polymers on the surface of the polypeptide are preferred according to the invention. For enzymes especially enzymes having no or only very few polymers (i.e. 0 to 2) coupled within a distance of 0 to 5 A, preferably 0 to 10 A from the active site are preferred. The enzyme activity The parent enzyme may have any activity known to be used in industrial composition and products as defined below.

As mentioned above preferred enzymes have Lysines spread broadly over the surface. PD498 has no Lysine residues in a distance of 0-10 A from the active site which makes it especially suitable in modified form. Further, the Lysine residues are spread broadly on the surface of the enzyme (i.e. away from the active site) . The enzyme Subtilisin DY has a molecular weight of 27 kDa and has 12 amino groups (i.e. Lysine residues) on the surface of the enzyme and one N-terminal amino group (see SEQ ID NO: 3) .

Industrial composition In a further aspect of the invention relates to an "industrial composition" comprising a modified polypeptide with reduced allergenicity. In the context of the present invention an "industrial composition" means a composition which is not intended to be introduced into the circulatory system. In other words it means a composition which is not intended for intradermally, intravenously or subcutaneously administration. As mentioned above the main problem for polypeptides, such as enzymes, for industrial application is the potential risk of respiratory allergy caused by inhalation through the respiratory system i.e. intratracheally or intranasal exposure. Examples of "industrial composition" are polypeptides, especially enzymes and anti-microbial polypeptides, used in compositions or products such as detergents, including laundry and dish washing detergents, household article products, agro-chemicals, personal care products, such as skin care products, including cosmetics and toiletries, oral and dermal pharmaceuticals, compositions used for treating/processing textiles, compositions for hard surface cleaning, and compositions used for manufac- turing food and feed, including food or feed additives, such as additives for making bread or the like etc. Especially contemplated according to the invention are skin care products and detergents.

Proteases Proteases are effective ingredients in skin cleaning products. Proteases remove the upper layer of dead keratinous skin cells and thereby makes the skin look brighter and more fresh. Further, proteases also improves the smoothness of the skin. Proteases are used in toiletries, bath and shower products, including shampoos, conditioners, lotions, creams, soap bars, toilet soaps, and liquid soaps. Lipases Lipases can be applied for cosmetic use as active ingredients in skin cleaning products and anti-acne products for removal of excessive skin lipids, and in bath and shower products such as creams and lotions as active ingredients for skin care. Lipases can also be used in hair cleaning products (e.g. shampoos) for effective removal of sebum and other fatty material from the surface of hair. Oxidoreductases The most common oxidoreductase for personal care purposes is an oxidase (usually glucose oxidase) with substrate (e.g. glucose) that ensures production of H 2 0 2 , which then will initiate the oxidation of for instance SCN " or I " into antimicrobial reagents (SCNO " or I 2 ) by a peroxidase (usually lactoperoxidase) . This enzymatic complex is known in nature from e.g. milk and saliva. It is being utilised commercially as anti-microbial system in oral care products (mouth rinse, dentifrice, chewing gum) where it also can be combined with an amyloglucosidase to produce the glucose. These systems are also known in cosmetic products for preservation. Another application of oxidoreductases are oxidative hair dyeing using oxidases, peroxidases and laccases (See e.g. WO 96/00290 or WO 95/33836 from Novo Nordisk) . Free radicals formed on the surface of the skin (and hair) known to be associated with the ageing process of the skin (spoilage of the hair) . The free radicals activate chain reactions that leads to destruction of fatty membranes, collagen, and cells. The application of free radical scavengers such as Superoxide dismutase into cosmetics is well-known (R. L. Goldemberg, DCI, Nov. 93, p. 48-52) . Protein disulfide isomerase (PDI) is also an oxidoreductase . It may be utilised for waving of hair (reduction and reoxidation of disulfide bonds in hair) and repair of spoiled hair (where the damage is mainly reduction of existing disulfide bonds) . Transglutaminase Skin care compositions for application to human skin, hair or nails comprise (a) an amino-functional active ingredient, (b) transglutaminase to catalyse cross-linking of the active ingredient to the skin, hair or nails, and (c) a carrier is known from US patent no. 5,490,980. A cosmetic composition suitable for application to mammalian skin, hair or nails comprising: (a) at least one corneocyte envelope protein in an amount sufficient to provide a protective layer on said skin, hair or nails; (b) a transglutaminase in an amount sufficient to form covalent bonds between the corneocyte envelope protein and externally exposed corneocyte proteins present in the stratum corneum of said skin, hair or nails; (c) calcium ions in an amount sufficient to activate the transglutaminase; and (d) a cosmetically acceptable vehicle, wherein the composition comprises an emulsion having two phases and wherein the corneocyte envelope protein is contained in one of the phases and the transglutaminase is contained within the other phase (see US patent no. 5,525,336). JP 3083908 describes a skin cosmetic material contains a transglutaminase modified with a water-soluble substance. The modifying substance is, e.g., one or more of polyethylene glycol, ethylene glycol, propylene glycol, glycerine, polyvinyl alcohol, glucose, sucrose, alginil acid, carboxymethyl cellulose, starch, and hydroxypropyl cellulose. The modification is done, e . g. , by introducing reactive groups and bonding to the enzyme. For providing a material mild to the skin, causing less time-lapse discolouring and odorising, and having good effects of curing rough skin, retaining moisture, and conditioning the skin beautifully.

The detergent composition according to the invention can be in liquid, paste, gels, bars or granular forms. The pH (measured in aqueous solution at use con-centration) will usually be neutral or alkaline, e.g. in the range of 7-11. Granular compositions according to the pre-sent invention can also be in "compact form", i.e. they may have a relatively higher density than conventional granular detergents, i.e. form 550 to 950 g/1. The enzyme conjugate of the invention, or optionally another enzyme incorporated in the detergent composition, is normally incorporated in the detergent composition at a level from 0.00001% to 2% of enzyme protein by weight of the composition, preferably at a level from 0.0001% to 1% of enzyme protein by weight of the composition, more preferably at a level from 0.001% to 0.5% of enzyme protein by weight of the composition, even more preferably at a level from 0.01% to 0.2% of enzyme protein by weight of the composition. Surfactant system The surfactant system may comprise nonionic, anionic, cationic, ampholytic, and/or zwitterionic surfactants. The surfactant system preferably consists of anionic surfactant or a combination of anionic and nonionic surfactant, e.g. 50-100 % of anionic surfactant and 0-50 % nonionic. The laundry detergent compositions may also contain cationic, ampholytic, zwitterionic, and semi-polar surfactants, as well as the nonionic and/or anionic surfactants other than those already described herein. The surfactant is typically present at a level from 0.1% to 60% by weight. Some examples of surfactants are described below. Nonionic surfactant The surfactant may comprise polyalkylene oxide (e.g. polyethylene oxide) condensates of alkyl phenols. The alkyl group may contain from about 6 to about 14 carbon atoms, in a straight chain or branched-chain. The ethylene oxide may be present in an amount equal to from about 2 to about 25 moles per mole of alkyl phenol. The surfactant may also comprise condensation products of primary and secondary aliphatic alcohols with about 1 to about 25 moles of ethylene oxide. The alkyl chain of the aliphatic alcohol can either be straight or branched, and generally con- tains from about 8 to about 22 carbon atoms. Further, the nonionic surfactant may comprise polyethylene oxide conden-sates of alkyl phenols, condensation products of primary and secondary aliphatic alcohols with from about 1 to about 25 moles of ethylene oxide, alkylpolysaccharides, and mixtures hereof. Most preferred are C8-C14 alkyl phenol ethoxylates having from 3 to 15 ethoxy groups and C8-C18 alcohol ethoxylates (preferably CIO avg.) having from 2 to 10 ethoxy groups, and mixtures thereof. Anionic surfactants Suitable anionic surfactants include alkyl alkoxyla-ted sulfates which are water soluble salts or acids of the formula R0(A)mS03M wherein R is an unsubstituted C10-C-24 alkyl or hydroxyalkyl group having a C10-C24 alkyl com-ponent, preferably a C12-C20 alkyl or hydroxyalkyl, more pre-ferably C12-C18 alkyl or hydroxyalkyl, A is an ethoxy or propoxy unit, m is greater than zero, typically between about 0.5 and about 6, more preferably between about 0.5 and about 3, and M is H or a cation which can be, for example, a metal cation (e.g., sodium, potassium, lithium, calcium, magnesium, etc.), ammonium or sub- stituted-ammonium cation. Alkyl ethoxy-lated sulfates as well as alkyl propoxylated sulfates are contemplated herein. Specific examples of substituted ammonium cations include methyl-, dimethyl, trimethyl-ammonium cations and quaternary ammo-nium cations such as tetramethyl-ammonium and dimethyl piperdinium cations and those derived from alkylamines such as ethylamine, diethylamine, triethyla-mine, mixtures thereof, and the like. Other suitable anionic surfactants include the alkyl sulfate surfactants which are water soluble salts or acids of the formula ROS03M wherein R preferably is a C10-C24 hydrocarbyl, preferably an alkyl or hydroxyalkyl having a C10-C20 alkyl component, more preferably a C12-C18 alkyl or hydroxyalkyl, and M is H or a cation, e.g., an alkali metal cation (e.g. sodium, potassium, lithium) , or ammonium or substituted ammonium. Other anionic surfactants include salts (including, for example, sodium, potassium, ammonium, and substituted ammonium salts such as mono- di- and triethanola-mine salts) of soap, C8- C22 primary or secondary alkanesulfonates, C8-C24 olefinsul- fonates, sulfonated polycarboxylic acids prepared by sulfonation of the pyrolyzed product of alkaline earth metal citrates. Alkylbenzene sulfonates are suitable, especially linear (straight-chain) alkyl benzene sulfonates (LAS) wherein the alkyl group preferably contains from 10 to 18 carbon atoms. The laundry detergent compositions typically comprise from about 1% to about 40%, preferably from about 3% to about 20% by weight of such anionic surfactants. Builder system The compositions according to the present invention may further comprise a builder system. Any conventional builder system is suitable for use herein including aluminosilicate materials, silicates, polycarboxylates and fatty acids, materials such as ethylenediamine tetraacetate (EDTA) , metal ion sequestrants such as aminopolyph-osphonates . Phosphate builders can also be used herein. Suitable builders can be an inorganic ion exchange material, commonly an in-organic hydrated aluminosilicate material, more particularly a hydrated synthetic zeo-lite such as hydrated zeolite A, X, B, HS or MAP. Detergency builder salts are normally included in amounts of from 5% to 80% by weight of the composition. Preferred levels of builder for liquid detergents are from 5% to 30%. Other detergent enzyme activities The detergent composition may, in addition to the conjugate of the invention with a specific activity, further comprise other enzyme activities e.g. also in the form of an enzyme conjugate as described according to the present invention, providing cleaning performance and/or fabric care benefits, e.g. proteases, lipases, cutinases, amylases, cellulases, peroxidases, haloperoxidases, oxidases (e.g. laccases). Specific examples of contemplated enzymes are listed abobe in the section "The enzyme activity". Bleaching agents: The detergent composition (especially in the case of a granular detergent) may also comprise a bleaching agents, e.g. an oxygen bleach or a halogen bleach. The oxyugen bleach may be a hydrogen peroxide releasing agent such as a perborate (e.g. PB1 or PB4) or a percarbonate, or it may e.g. be a percarboxylic acid. The parti-cle size may be 400-800 microns. When present, oxygen bleching compounds will typically be present at levels of from about 1% to about 25%. The hydrogen peroxide releasing agent can be used in combination with bleach activators such as tetra- acetylethylenediamine (TAED) , nonanoyloxybenzene-sulfonate (NOBS), 3, 5-trimethyl-hexsanoloxybenzene-sulfonate (ISONOBS) or pen-taacetylglu-cose (PAG). The halogen bleach may be, e.g. a hypohalite bleaching agent, for example, trichloro isocyanuric acid and the sodium and potassium dichloroisocyanurates and N-chloro and N-bromo alkane sulphonamides. Such materials are nor-mally added at 0.5-10% by weight of the finished product, preferably 1-5% by weight. Textile applications Proteases Proteases are used for degumming and sand-washing of silk. Lipases Lipases are used for removing fatty matter containing hy-dro- phobic esters (e.g. triglycerides) during the finishing of textiles (see e.g. WO 93/13256 from Novo Nordisk A/S). Oxidoreductases In bleach clean-up of textiles catalases may serve to remove excess hydrogen peroxide. Carbohydrases Cellulolytic enzymes are widely used in the finishing of denim garments in order to provide a localized variation in the co-lour density of the fabric (Enzyme facilitated "stone wash"). Also cellulolytic enzymes find use in the bio-polishing process. Bio-Polishing is a specific treatment of the yarn surface which improves fabric quality with respect to handle and ap- pear-ance without loss of fabric wettability. Bio-polishing may be obtained by applying the method described e.g. in WO 93/20278. During the weaving of textiles, the threads are exposed to con-siderable mechanical strain. In order to prevent breaking, they are usually reinforced by coating (sizing) with a gelatinous substance (size) . The most common sizing agent is starch in native or modified form. A uniform and durable finishing can thus be obtained only after removal of the size from the fabric, the so called desizing. Desizing of fabrics sized with a size containing starch or modified starch is preferably fa-cili-tated by use of amylolytic enzymes. Food and Feed applications Conjugated enzymes or polypeptides of the invention may advantageously be used in the manufactur-ing of food and feed. Proteases The gluten in wheat flour is the essential ingredient respon- sible for the ability of flour to be used in baked foodstuffs. Proteolytic enzymes are sometimes needed to modify the gluten phase of the dough, e.g. a hard wheat flour can be softened with a protease. Neutrase® is a commercially available neutral metallo protease that can be used to ensure a uniform dough quality and bread texture, and to improve flavour. The gluten proteins is degraded either moderately or more extensively to peptides, whereby close control is necessary in order to avoid excessive softening of the dough. Proteases are also used for modifying milk protein. To coagulate casein in milk when producing cheese proteases such as rennet or chymosin may be used. In the brewery industry proteases are used for brewing with unmalted cereals and for controlling the nitrogen content. In animal feed products proteases are used so to speak to expand the animals digestion system. Lipases The application of lipase in the baking industry is rather new. Addition of lipase results in improved dough properties and an improved breadmaking quality in terms of larger volume, im- pro-ved crumb structure and whiter crumb colour. The observed ef-fect can be explained by a mechanism where the lipase changes the interaction between gluten and some lipids fragment during dough mixing. This results in an improved gluten network. The flavour development of blue roan cheeses (e.g. Danablue) , certain Italian cheese types and other dairy products containing butter fat are dependent on the degradation of milk fat into free fatty acids. Lipases may be used for developing flavour in such products. In the oil- and fat producing industry lipases are used e.g. to minimize the amount of undesirable side-products, to modify fats by interesterification, and to synthesis of esters. Oxidoreductases Further oxidoreductases with reduced allergenicity according to the invention may advantageously be used in the manufacturing of food and feed. Several oxidoreductases are used for baking, glucose oxidase, lipoxygenase, peroxidase, catalase and combinations hereof. Traditionally, bakers strengthen gluten by adding ascorbic acid and potassium bromate. Some oxidoreductases can be used to replace bromate in dough systems by oxidation of free sulfydryl units in gluten proteins. Hereby disulphide linkages are formed resulting in stronger, more elastic doughs with greater resistance. Gluzyme® (Novo Nordisk A/S) is a glucose oxidase preparation with catalase activity that can be used to replace bromate. The dough strengthen is measured as greater resistance to mechanical shock, better oven spring and larger loaf volume. Carbohydrases Flour has varying content of amylases leading to differences in the baking quality. Addition of amylases can be necessary in order to standardize the flour. Amylases and pentosanases generally provide sugar for the yeast fermentation, improve the bread volume, retard retrogradation, and decrease the staling rate and stickiness that results from pentosan gums. Examples of carbohydrases is given below. Certain maltogenic amylases can be used for prolonging the shelf life of bread for two or more days without causing gumminess in the product. Selectively modifies the gelatinized starch by cleaving from the non-reducing end of the starch molecules, low molecu-lar wight sugars and dextrins. The starch is modified in such a way that retrogradation is less likely to occur. The produced low-molecular-weight sugars improve the baked goods water retention capacity without creating the intermediate-length dextrins that result in gumminess in the finished product. The enzyme is inactivated during bread baking, so it can be considered a processing aid which does not have to be declared on the label. Overdosing of Novamyl can almost be excluded. The bread volume can be improved by fungal α-amylases which further provide good and uniform structure of the bread crumb. Said α-amylases are endoenzymes that produce maltose, dextrins and glucose. Cereal and some bacterial α-amylases are inacti- vated at temperatures above the gelatinization temperature of starch, therefore when added to a wheat dough it results in a low bread volume and a sticky bread interior. Fungamyl has the advantage of being thermolabile and is inactivated just below the gelatinization temperature. Enzyme preparations containing a number of pentosanase and hemi-cellulase activities can improve the handling and stabil- ity of the dough, and improves the fresh-ness, the crumb structure and the volume of the bread. By hydrolysing the pentosans fraction in flour, it will lose a great deal of its water-binding capacity, and the water will then be available for starch and gluten. The gluten becomes more pliable and extensible, and the starch gelatinize more easily. Pentosanases can be used in combination with or as an alternative to emulsifi-ers . Further carbohydrases are user for producing syrups from starch, which are widely used in soft drinks, sweets, meat products, dairy products, bread products, ice cream, baby food, jam etc. The conversion of starch is normally carried out three steps. First the starch is liquefied, by the use of α-amylases. Maltodextrins, primary consisting of oligosaccharides and dextrins, are obtained. The mixture is then treated with an amyloglucosidase for hydrolysing the oligosaccharides and dextrins into glucose. This way a sweeter product is obtained. If high maltose syrups are desired b-amylases alone or in combina-tion with a pullulanase (de-branching enzyme) may be used. The glucose mixture can be made even sweeter by isomerization to fructose. For this an immobilized glucose isomerase can be used. In the sugar industry, it is common practice to speed up the break down of present starch in cane juices. Thereby the starch content in the raw sugar is reduced and filtration at the refinery facilitated. Furthermore dextranases are used to break down dextran in raw sugar juices and syrups. In the alcohol industry a-amylases is advantageously being used for thinning of starch in distilling mashes. In the brewing industry a-amylases is used for adjunct liquefaction. In the dairy industry b-galactosidases (lactase) is used when producing low lactose milk for persons suffering from lactose malabsorption . When flavoured milk drinks are produced from lactase-treated milk, the addition of sugar can be reduced without reducing the sweetness of the product. In the production of condensed milk, lactose crystallization can be avoided by lactase treatment, and the risk of thickening caused by casein coagulation in lactose crystals is thus reduced. When producing ice cream made from lactase-treated milk (or whey) no lactose crystals will be formed and the defect, sandiness, will not occur. Further, xylanases are known to be used within a number of food/feed industrial applications as described in WO 94/21785 (Novo Nordisk A/S) . α-amylases are used in the animal feed industry to be added to cereal-containing feed to improve the digestibility of starch. Anti-microbial polypeptides Certain bacteriolytic enzymes may be used e.g. to wash carcasses in the meat packing industry (see US patent no. 5,354,681 from Novo Industri A/S) . Transferases Transglutaminases with reduced allergenicity according to the invention may advantageously be used in the manufacturing of food and feed. Transglutaminases has the ability to crosslinking protein. This property can be used for gelling of aqueous phases containing proteins. This may be used for when producing of spreads (wo 96/08156 from Novo Nordisk A/S) . Transglutaminases are being used for improve-ment of baking quality of flour e.g. by modifying wheat flour to be used in the pre-paration of cakes with improved properties, such as improved taste, dent, mouth-feel and a higher volume (see JP 1-110147) . Further producing paste type food material e.g. used as fat substitution in foods as ice cream, toppings, frozen desserts, mayonnaises and low fat spreads (see WO 93/22930 from Novo Nordisk A/S) . Furthermore for preparation of gels for yoghurt, mousses, chee-se, puddings, orange juice, from milk and milk-like products, and binding of chopped meat pro-duct, improve-ment of taste and texture of food proteins (see WO 94/21120 and WO 94/21129 from Novo Nordisk A/S) . Phytases Phytases of the invention may advantageously be used in the manufacturing of food, such as breakfast cereal, cake, sweets, drink, bread or soup etc., and animal feed. Phytases may be used eit-her for exploiting the phosphorus bound in the phytate/phytic acid present in vegetable protein sources or for exploiting the nutritionally important minerals bound in phy-tic acid com-plexes. Microbial phytase may be added to fe-ed-stuff of monogastric animals in or-der to avoid supplementing the feed with inorganic phosphorus (see US patent no. 3,297,548) Further phytases may be used in soy processing. Soya-bean meal may con-tain high levels of the anti-nutritional factor phytate which renders this protein source unsuitable for application in baby food and feed for fish, calves and other non-ruminants, since the phytate chelates essential minerals present therein (see EP 0 420 358) . Also for baking purposes phytases may be used. Bread with better quality can be prepared by baking divided pieces of a dough containing wheat flour etc. and phytase (see JP-0-3076529- A) . A high phytase activity koji mold are known to be used for producing refined sake (see JP-0-6070749-A) .

These fractions was stored at -20 °C intil use. 25 Additionally, 100 μl of the respective factions was stored in the lab-freezer at -20°C for immunochemical analysis at the beginning, halfway and at the end of the study. For each immunization and each analysis a new fraction was taken. Twenty intratracheal immunizations was performed weekly with 30 100 μl of the protein dilution mentioned before. Thus, group 1 received unmodified PD498, group 2 PD498-EO 50 PO 50 970, group 3 unmodified Subtilisin DY (CDJ31) , group 4 Subtilisin DY (CDJ31)- EO 50 PO 50 970, group 5 Sutilisin DY (CDJ31) -EO 40 PO 60 2900, group 6 Neutrase and group 7 Neutrase-EO 50 PO 50 970. Each group contained 35 10 rats. Control rats received 100 μl 0.9% NaCl. Blood samples (2 ml) was collected from the eye one week after every second immunization. Serum was obtained by blood clothing, and centrifugation. Specific IgE levels was determined using the ELISA procedure. The figure shows that the IgE response is reduced for the modified enzymes compared to unmodified enzyme.
