Title:
CHEMICALLY MODIFIED LIPASE AND ENZYME REACTION USING THE SAME
Document Type and Number:
Japanese Patent JPH01168282
Kind Code:
A
Abstract:
PURPOSE: To simply obtain a chemically modified lipase reduced in lowering of a catalyst activity in an organic solvent, by modifying an amino group in lipase with a specific alkenylcinnamic anhydride or alkylketene dimer.
CONSTITUTION: An amino group in lipase is modified with an alkenylcinnamic anhydride expressed by formula I (R1 and R2 are 10W20C alkyl or alkenyl group) or alkylketene dimer expressed by formula II (R3 and R4 are 10W20C alkyl or alkenyl group). Hydrolysis of oils and fats or fatty acid esters can be efficiently carried out in an organic solvent or two phase system of water- organic solvent by using the above-mentioned method.
