MICROBIOLOGICALLY PRODUCED L-PHENYLALANINE DEHYDROGENASE, OBTAINING METHOD THEREOF AND PRODUCTION OF L-ALPHA-AMINO- CARBOXYLIC ACID

摘要

The invention is directed to a microbiologically produced L-phenylalanine-dehydrogenase and a process for its recovery from Brevibacterium species DSM 2448. The new enzyme can be used for the enzymatic conversion of phenyl pyruvic acid, p-hydroxyphenyl pyruvic aid, indolyl pyruvic acid or 2-keto-4-(methylmercapto)-butyric acid into the corresponding L- alpha -aminocarboxylic acids.
