Enzyme preparation and method of using the same

摘要

There is disclosed are an enzyme preparation characterized by a polymer carrier having fine pores with average radius of 200-500 Å and the enzyme is capable of converting an N-substituted cyclic imino ester into an (S)-N-substituted cyclic imino acid, thereby an (S)-N-substituted cyclic imino acid is preferentially produced, and has an amino acid sequence as set forth in SEQ ID NO: 1 or the like.
