5-substituted hydantoin racemase, DNA coding for the same, and process for producing optically active amino acids

摘要

A protein having a 5-substituted hydantoin racemase activity, which has the amino acid sequence (a) or (b). Where (a) is the amino acid sequence set forth in SEQ ID NO:2 in the Sequence Listing, and (b) is an amino acid sequence wherein in the amino acid sequence set forth in SEQ ID NO:2 in the Sequence Listing, one or more amino acid residues have been replaced, deleted, inserted, added or inverted.
