Abstract
The present invention has its object to provide a method for producing an L-amino acid comprising reacting a keto acid with an amino acid dehydrogenase and an enzyme having coenzyme regenerating ability to convert to a L-amino acid, wherein a coenzyme is added in two or more portions in the reaction. The method of the present invention enables efficient production of an L-amino acid useful as a synthetic intermediate such as a pharmaceutical intermediate with high optical purity by an enzymatic reductive amination independent of the purity of the keto acid used as a substrate.
