ABSTRACT:
The present invention provides a protein having low-substrate-specific amino acid racemase activity; DNA encoding the protein; a recombinant DNA comprising the DNA; a transformant carrying the recombinant DNA; a process for producing the protein by using the transformant; and a process for producing a racemic amino acid which comprises allowing a culture of the transformant or a treated matter thereof as an enzyme source and an amino acid to be present in an aqueous medium to racemize the amino acid in the aqueous medium, and recovering the racemic amino acid from the aqueous medium.
