Polypeptides conjugated to copolymers of ethylene oxide and propylene oxide to reduce allergenicity
摘要:
A polypeptide-polymer conjugate is prepared having one or more polymers covalently bound to a polypeptide. The polymer has the general formula; EOXPOY wherein EO is ethylene oxide, PO is propylene oxide, x=1−99%, y=1−99%, x+y=100%, and x and y are in a ratio range of 10:90 to 90:10, more preferably 40:60 to 60:40, or in a 50/50 ratio. The polymer, which can be a block polymer, typically has a molecular weight in a range of 100 to 100,000 daltons, and the polypeptide may contain 1 to 100 polymer molecules. Coupling the polypeptide, in particular enzymes, to the polymer reduces respiratory allergenicity of the polypeptide. Industrial compositions such as detergent compositions, personal care compositions, compositions for processing/treating textiles, and food and feed compositions containing the polypeptide-polymer conjugate have reduced respiratory allergenicity.
