Abstract
The present invention relates to acylamino acid racemase, production and use thereof. The acylamino acid racemase of the present invention racemizes optically active N-acyl-.alpha.-aminocarboxylic acid alone at pH values around the neutral level at a normal temperature under normal pressure in the presence of optical active amino acid; its use in combination with D- or L-aminoacylase enables the production of optically active D- or L-.alpha.-amino acid from DL-acyl-.alpha.-aminocarboxylic acid at a high level of efficiency.
