PROBLEM TO BE SOLVED: To provide a phospholipase D which is high in safety and is available in food field at ease and moreover retains high hydrolysis activity or polar group exchanging activity.SOLUTION: After a filtrate fluid in which peaches or eggplants are crushed to be filtered or a supernatant fluid upon centrifugation is mixed with an organic solvent such as acetone, a crude enzyme is taken out by freeze-drying or the like he formed precipitates if necessary. For example, when phosphatidylserine is produced using phosphatidylcholine as a raw material, the crude enzyme is used as an enzyme. |
