METHOD FOR PRODUCING L-PHENYLSERINE DEHYDROGENASE

摘要

PROBLEM TO BE SOLVED: To provide a useful L-phenylserine dehydrogenase in order to efficiently produce an optically active β-hydroxy-α-amino acid having utility value as a synthetic raw material for medicines, etc.

SOLUTION: A protein having L-phenylserine dehydrogenase activity produces the optically active β-hydroxy-α-amino acid by favorably reacting with L-threo and erythro-β-hydroxy-α-amino acid with nicotineamideadeninedinucleotide used as a coenzyme and oxidizing hydroxy group in β-position of the amino acid.
