Abstract
Official abstract text for this publication.
The present invention relates to novel polypeptides having nuclease activity and the use and methods for preventing or reducing creases of a fabric; a composition comprising such polypeptide. The invention further related to polynucleotide encoding polypeptides having nuclease activity.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising nuclease having DNase and RNase activity, wherein the composition further comprises; (a) one or more polyol(s), selected from glycerol, (mono, di, or tri) propylene glycol, ethylene glycol, polyethylene glycol, sugar alcohols, sorbitol, mannitol, erythritol, dulcitol, inositol, xylitol and adonitol, (b) one or more enzyme(s), selected from proteases, amylases or lipases, (c) one or more surfactant(s), selected from anionic and nonionic surfactants, and (d) one or more polymers. 2. The composition of claim 1 , wherein the polymer is poly(vinylimidazole) (PVI), poly(vinylpyridine-N-oxide) (PVPO or PVPNO), polyvinylpyrrolidone-vinylimidazole (PVPVI) or an amphiphilic carboxyalkylated polyamine. 3. The composition of claim 1 , wherein the nuclease has at least 10% but less than 100% RNase activity. 4. A method for modifying a fabric material comprising (a) treating the fabric with the composition of claim 1 ; (b) under conditions leading to a modified fabric, wherein the modified fabric possesses a fabric improvement compared to the unmodified fabric. 5. A method for preventing or reducing creases and/or improving softness of a fabric comprising the steps of: a) contacting the fabric with the composition of claim 1 ; and b) rinsing the fabric. 6. The method of claim 4 , wherein the nuclease has at least 10% but less than 100% RNase activity of the total nuclease activity. 7. The method of claim 4 , wherein the nuclease has at least 80% sequence identity to the polypeptide comprising the amino acid sequence of SEQ ID NO 2.
