Novel phospholipid processing agent

摘要

Problems: It is an object of the present invention to provide a novel phospholipase B (PLB) having less hydrolytic activity on phosphatidylinositol (PI) among diacyl form of the phospholipid. Also, it is an object of the invention to provide a method of efficiently manufacturing PI and glyceryl phosphoryl choline (GPC) from a phospholipid mixture by using a substrate specificity of an enzyme. Means to Solve the Problems: Provided is a phospholipid processing agent containing an enzyme, which acts effectively on a phospholipid other than PI, such as phosphatidyl choline (lecithin), and having less PLB activity on PI.
