Title:
PROCESS FOR PRODUCING D-AMINO ACID BY USING COMPOSITE IMMOBILIZED ENZYME PREPARATION
Document Type and Number:
WIPO Patent Application WO/1996/000296
Kind Code:
A1
Abstract:
A process for producing a D-amino acid from a DL-5-substituted hydantoin in one step readily and efficiently by using a composite immobilized enzyme preparation at a pH in the vicinity of neutrality, which preparation is produced by immobilizing both of a hydantoinase having an optimum pH in an alkaline region and a D-N-carbamyl-'alpha'-amino acid amide hydrolase having an optimum pH in the vicinity of neutrality on an immobilizing carrier at the same time.
