Abstract
Hydantoinase enzymes which are mutants of a previously isolated hydantoinase having the amino acid SEQ. ID. NO. 2. The mutants include amino acid substitutions at positions 95, 154, 180, 251 and/or 255 of the wild type hydantoinase (SEQ. ID. NO. 2). The mutant hydantoinases, like the parent hydantoinase, are used in the production of optically pure amino acids.
