Description

WO 00/04138 PCT/DK99/00406 _ TITLE: A polypeptide-polymer conjugate with improved wash performance FIELD OF THE INVENTION
The present invention relates to a polypeptide-polymer conjugate wherein the polymer is a homopolymer , 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 io invention, the use of a polypeptide-polymer conjugate of the invention for improving the wash performance of industrial compositions and products, and finally a method for improving the wash performance of polypeptides.
BACKGROUND OF THE INVENTION
In the detergent industry enzymes have for more than 30 years been implemented in washing formulations. Enzymes used in such formulations comprise proteases, lipases, amylases, cellulases, as well as other enzymes, or mixtures thereof.
2o Commercially most important enzymes are proteases.
An increasing number of commercially used enzymes e.g.
proteases are protein engineered variants of naturally occurring wild type proteases, e.g. DURAZYM° (Novo Nordisk A/S), RELASE' (Novo Nordisk A/S), MAXAPEM~ (Gist-Brocades N.V.), PURAFECT° (Genencor International, Inc.).
However, even though a number of useful enzyme variants have been described in the literature, there is still a need for new improved enzyme or enzyme variants for a number of industrial uses.
As polypeptides may potentially cause an und2sired 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.
WO 97/24421 and WO 97/24427 discloses the immobilization of s5 enzymes by covalent binding on an activated polymer. The immobilization of one or more enzymes using an activated polymer has inter alia shown improved antigenicity profile of the enzyme protein. The inventors state that the advantages can be achieved SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ by structurally modifying the enzyme without affecting the enzyme performance profile in the detergent solution.
Although, immobilization should avoid the formation of airborne material, this method still represent a risk of dust or s aerosol formation during handling and processing of the immobilisation step.
Another 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 io 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 is 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).
2o One of the theories explaining the reduced immune response is that the polymeric molecules) shields) 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 2s 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), polyethylene glycol (PEG), or propylene oxide (PO), polypropylene glycol (PPG).
3o Saccharides, 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 3s polypeptide conjugates coupled to polymeric molecules, in particular polyethylene glycol (PEG).
The present inventors have now surprisingly found that the SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ polymer-polypeptide conjugates have improved wash performance in comparison to the unmodified polypeptide.
StJi4~lARY OF THE INVENTION
s In it first aspect the present invention relates to a polypeptide-polymer conjugate with improved wash performance.
The present inventors have found that when coupling homo-polymers with a molecular weight in the range of 0.1 kDa to 60 kDa to a parent polypeptide with a molecular weight of between 4 io kDa and I00 kDa the wash performance of the polypeptide is improved compared to the wash performance of the parent polypeptide.
The present inventors have further found that when coupling graft, block, alternate, or random co-polymers with the general is formula:
EOYPOY (I) wherein x=1-99~, y=1-99~ and x+y=100 covalently to a parent 2o polypeptide, used for industrial application, the wash performance is improved when compared to the parent polypeptide.
In both cases the respiratory allergenicity may also be reduced when compared to the parent enzyme. I the latter case the respiratory allergenicity may even be reduced when compared 2s 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.
3o In a third aspect the invention relates to the use of conjugates for improving wash performance and a final aspect the invention relates to a method for improving wash performance of polypeptides.
35 _Industrial polypeptides Polypeptides used for industrial applications often have an enzymatic and/or anti-microbial activity. Industrial SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ polypeptides are (in contrast to pharmaceutical polypeptides) nat intended to be introduced into the circulatory system of the body.
Therefore, it is not very likely that industrial s 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, composition for treating textiles, and personal care products, including cosmetics, come into direct contact with the io circulatory system of the body of humans or animals, as such polypeptide~ (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 conse is quence of inhalation of polypeptides through the respiratory passage.
In the context of the present invention "industrial polypep-tides" are defined as polypeptides, including peptides, proteins and/or enzymes, which are not intended to be introduced into the 2o circulatory system of the body of humans and/or animals.
Examples of such polypeptide include polypeptides with enzymatic activity as defined below.
However, when coupling one or more polymers to an enzyme the performance of said enzyme will remain approximately the same or 2s decrease as compared to the parent enzyme.
The catalytic performance of an enzymes depends among many things on the contact between the enzyme and the substrate at the active site(s). When coupling polymers to an enzyme the polymers will normally be distributed in a random manner on the so surface of the enzyme. Also polymers will be coupled to the enzyme near the active site of said enzyme which leads to steric or spatial hindrance. One will therefore expect that the enzyme performance will be adversely affected.
The present inventors have surprisingly found that enzyme 35 performance may be increased by conjugation to polymers.
DETAILED DESCRIPTION OF TSE INVENTION
SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ The present inventiors have now surprisingly suceeded in providing polypeptide-polymer conjugates, wherein the catalytic performance of the polypeptide is improved.
The present invention relates to a polypeptide-polymer s conjugate suitable for industrial applications and incorporation as active ingredients in industrial products. Conjugates of the invention may also have reduced respiratory allergenicity.
The term "polypeptide-polymer conjugate" means in the context of the present invention that one or more polymers have io been covalent bound to the polypeptide.
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 i5 a modified polypeptide of the invention in comparison to the corresponding parent polypeptide. The term "respiratory allergenicity" may be used instead. The term "improved wash performance" means in the context of the present invention that the delta reflectance value of test material washed with the 2o conjugate has increased compared to the delta reflectance value of test material washed with the parent enzyme (non-conjugate).
When the term "improved wash performance" is used in connection with e.g. skin care products, where no delta reflectance values are available, the term means that the 25 cleansing effect has improved compared to the cleansing effect when using the parent enzyme (non-conjugate).
The present inventors have found that when a parent unmodified polypeptide is coupled to homo-polymers, graft, block, alternate, or random co-polymers the wash performance is 3o improved. The potential allergenic response caused by inhalation of the polypeptide may also be reduced in comparison to a corresponding parent unmodified polypeptide.
In one aspect in the invention relates to conjugates, wherein the parent polypeptide may be coupled to polymeric ss molecules with a molecular weight in the range from 100 Da up to 10,000 Da, preferably 100 Da to 5,000 Da, more preferably 100 to 2,000 Da, especially 100 to 1,000 Da.
SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ It is advantageous to couple short/light polymeric molecules to the polypeptide in question as short/light polymeric molecules are known to have less tendency to inhibit a functional activity of the polypeptide. For instance, the active s site of an enzyme coupled to polymeric molecules having a molecular weight as defined according embodiments of the present invention is easier accessible for the substrate in comparison to the corresponding enzyme coupled to larger/heavier polymeric molecules as the spatial hindrance by the polymeric molecules is io less pronounced. Further, a polypeptide-polymer conjugate with smaller/lighter polymeric molecules has improved stability in comparison to a corresponding conjugate with larger/heavier polymeric molecules coupled to the polypeptide, as deformation of the polypeptide structure is minimal due to the fact that is less weight is pulling the polypeptide structure in diffrent directions.
Another advantage of using small polymeric molecules is that they are cheaper to purchase as polymers are sold per kilo. This reduces the cost of producing a conjugate of the invention.
2o Furthermore, in comparison to immobilized enzymes, e.g.
multiple covalent attachment of enzymes to an activated polymer with multiple reactive groups, conjugates of the invention display individual polymer molecules covalenty attached to the protein surface. Thus avoiding cross-linking of enzymes, leads 2s to more equal and increased distribution of the catalyst in the application medium. This may lead to a better performance of the conjugates of the invention per unit protein in comparison to immobilized enzymes.
It is well known, that a polymer can adopt different so conformation/morphologies depending mainly, but not only on its molecular architecture, the solvent (here water), the temperature, and the concentration (S. Forster and M.
Antonietti, Adv. Mater, 1998, 10, No.3, pp 195-217). Those conformation/morphologies include micelles of various shapes, 35 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 SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ 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 s the polypeptide surface adopts a conformation in 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 io 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 is more difficult for the antibody to "find its way" (through the more ridgid 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 2o an influence on the potential allergenicity of a polypeptide polymer conjugate.
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 2s the properties of the attached polymers, optimized properties for different formulations, e.g. detergents, can be obtained.
In another 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 3o by the general formula:
EOKPOy (I) 3s wherein x=1-99~, y=1-99~, 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$.
SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ 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.
s In a preferred embodiment said polymer has a molecular 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 1o Da.
In an embodiment of the 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.
zs 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 2o 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 2s to identify respiratory allergens as a function of elicitation reactions induced in previously sensitised animals. According to these models the alleged allergens are introduced intratrach-eally into the animals.
A suitable strain of guinea pigs, the Dunkin Hartley strain, so do not as humans, produce IgE antibodies in connection with the allergic response. However, they produce another type of anti body the IgGlA and IgGlB (see e.g. Prentrz, ATLA, 19, p. 8-14, 1991), which are responsible for their allergenic response to inhaled polypeptides including enzymes. Therefore, when using 35 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 polypep-SUBSTITUTE SHEET {RULE 26) WO 00/04138 PCT/DK99/00406 _ 9 _ tides, 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 s and Applied Toxicology, 33, p. 1-10.
Other animals such as e.g. rabbits may also be used for comparable studies.

Generally seen polyalkylene oxides (PAO), such as polyethylene oxides, such as PEG and especially PEG, are the preferred polymeric molecules, as these polymeric molecules, in comparison to polysaccharides such as dextran, pullulan and the 2s like, have few reactive groups capable of cross-linking, which is undesirable.

SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ 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 s 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 io 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, is divinylsulfone, carbodiimide, sulfonyl halides, trichlorotri-azine etc. (see R.F. Tayior, (1991), "Protein immobilisation.

Press, Boca Raton; G.T. Hermanson et al., (1993), "Immobilized 2o 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, zs 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.
3o 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 po lypeptides may be performed with the aid of diimide and for e ss xample amino-PEG or hydrazino-PEG (Pollak et al., (1976), J. Am.
Chem. Soc., 98, 289-291) or diazoacetate/amide (along et al., (1992), "Chemistry of Protein Conjugation and Crosslinking", CRC

Coupling polymeric molecules to hydroxy groups axe generally very difficult as it must be performed in water. Usually hydrolysis predominates over reaction with hydroxyl groups.
s 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.
io 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 ms 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.: Aca-demic Press: Orlando, pp. 65-79; Scouten et al., (1987), Methods 2o in Enzymology vol. 135, Mosbach, K., Ed., Academic Press:
Orlando, 1987; pp 79-89: Crossland et al., (1971), J. Amr. Chem.
Soc. 1971, 93, pp. 4217-4219), mesylates (Harris, (1985), su ra;
Harris et al., (1984), J. Polym. Sci. Polym. Chem. Ed. 22, pp 341-352), aryl sulfonates like tosylates, and para-nitrobenzene zs 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 3o 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 3s the polypeptide..
Tosylate is more reactive than the mesylate but also more un-stable decomposing into PEG, dioxane, and sulfonic acid SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT1DK99/00406 _ (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 s 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 io (Allen et al., (1991), Carbohydr. Res., 213, pp 309-319), with para-nitrophenol, DMAP (EP 632 082 A1, (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.
is 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 2o 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 conju gate much more susceptible to hydrolysis (US patent no.
5,122,614, (1992), Zalipsky). This group may be activated with 2s 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, 30 375-378. Also the polymer can be coupled to the polypeptide through a pyrimidine ring (see US 4,144,128, US 4,195,128 and US
4,298,395).
Coupling of PEG to an aromatic amine followed by diazotation yields a very reactive diazonium salt which in situ can be 3s 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 SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ 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.
s 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.
General overviews of polymer activation and PEG
fuctionalization for the preparation of relevant conjugates is io given in Zaplisky, S., Bioconjugate Chem., 1995, 6, 150-165, Hermanson, G.T., Academic Press, San Diego, 1996, and S. Herman, G. Hooftman, E. Schacht, Journal of Bioactive and Compatible polymers, Vo1.10, 1995, 145-187.
is 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 2o 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, 2s 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 30 on the basis of parent polypeptides, typically having a molecular weight in the range from 4 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 35 polypeptide may preferably be of microbial origin, such as bacterial, filamentous fungus or yeast origin, or it may be of plant origin.
SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ The parent polypeptide may be a naturally-occurring (or wild-type) polypeptide or may be a variant thereof.
When choosing a parent polypeptide it is advantageous to use a polypeptide with the a high number of attachment groups.
s Further, in a preferred embodiment of the invention the polymers are spread broadly over the surface of the parent poly-peptide. 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 io 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 is antibodies when a low allergenic enzyme should be obtained. It is believed that the surface area of interaction between the polypeptide and an antibody lies in the range about 500 ~1z (26 x 19~) (see Sheriff et al. (1987), Proc. Natl. Acad. Sci. USA, Vol. 84, p. 8075).
2o 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 ~1, preferred 10 ~. from the active site.
2s 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 couple as many polymers to the attachment 3o 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 35 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 SUBSTITUTE SHEET (RULE 26) polymers (i.e. 0 to 2) coupled within a distance of 0 to 5 preferably 0 to 10 ~1 from the active site are preferred.

Industrial composition is In a further aspect of the invention relates to an "industrial composition" comprising a modified polypeptide with improved wash performance.
In the context of the present invention an "industrial composition" means a composition which is not intended to be 2o 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 2s respiratory allergy caused by inhalation through the respiratory system i.e. intratracheally or intranasal exposure.
Examples of "industrial composition" are polypeptides, espe-cially enzymes and anti-microbial polypeptides, used in composi-tions or products such as detergents, including laundry and dish 3o 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 etc. Especially contemplated according 3s to the invention are skin care products and detergents.

cover all personal care products used for cleansing, care and/or beautification of the skin of the body and further other products, such as hair care products, which during use may come 5 in contact with the skin or respiratory system. Also corresponding products for animals are contemplated according to the present invention.
Specific examples of skin care products contemplated according to the present invention are soap, cosmetics, io cleansing cream, cleansing lotion, cleansing milk, cream soap, whitening powder, powder soap, cake soap, transparent soap, nail polish remover, shampoo, balsam, hair rinse, etc.
Enzyme activities suitable for Skin Care i5 Skin care compositions of the invention comprise conjugates with improved wash or cleansing effect and e.g. reduced allergenicity of the invention and further ingredients known to be used in skin care compositions A number of enzyme activities are known to be used skin care 2o compositions.
Proteases Proteases are effective ingredients in skin cleaning products. Proteases remove the upper layer of dead keratinous 2s 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, 3o 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.
SUBSTITUTE SHEET (RULE 26) 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.
s Oxidoreductases The most common oxidoreductase for personal care purposes is an oxidase (usually glucose oxidase) with substrate (e. g.
glucose) that ensures production of H202, which then will initiate the oxidation of for instance SCN- or I- into anti-io microbial reagents (SCNO- or I2) 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) is 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
20 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 2s 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.
so 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 35 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 SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ ingredient to the skin, hair or nails, and (c) a carrier is known from US patent no. 5,490,980.

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 gly-2o col, ethylene glycol, propylene glycol, glycerine, polyvinyl alcohol, glucose, sucrose, alginil acid, carboxymethyl cellulo-se, 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 2s time-lapse discolouring and odorising, and having good effects of curing rough skin, retaining moisture, and conditioning the skin beautifully.

s Also cellulolytic enzymes find use in the bio-polishing pro-cess. Bio-Polishing is a specific treatment of the yarn surface which improves fabric quality with respect to handle and appear-ance without loss of fabric wettability. Bio-polishing may be obtained by applying the method described e.g. in WO 93/20278.
io 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 gelati-nous substance (size). The most common sizing agent is starch in native or modified form. A uniform and durable finishing can is 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 facilitated by use of amyiolytic enzymes.

pH of the detergent solution was adjusted to 10.5 with s HC1/NaOH. Water hardness was adjusted by adding CaCl2 and MgCl2 to deionized water (see also Surfactants in Consumer Products - Theory, Technology and Application, Springer Verlag 1986). pH of the detergent solution was adjusted to pH 10.5 by addition of HC1.
io Proteases present in the commercial powder detergents were inactivated by heating a detergent solution to 85°C for minutes in a microwave oven.
Reflectance measurements of the test material were done at 460 nm using a J&M Tidas MMS/16 photometer equipped with a is CLX 75W Xenon lamp and fibre optics. Each textile piece was measured individually with other textile pieces (same settings) as background.
SUBSTITUTE SHEET (RULE 26) WO 00/04138 PCT/DK99/00406 _ SAS 6.12 software was used to make an analysis of variance and a t-test comparison (Student-Newman-Keuls) at 95$ significance on the experimental data.
s The wash performance of the different Savinase~ variants was evaluated by comparing delta reflectance (DR) values:
DR = Rprotease - RBlank io DR: Delta reflectance RProtease~ Reflectance of test material washed with conjugated protease RBlank~ Reflectance of test material washed with non-is conjugated protease Results The capital letters designate statistical groupings within each column based on a t-test (SNK, a=0.05). If two 2o are in the same group (same letter), they cannot be separated statistically.
