ABSTRACT:
A process for the preparation of only one of the two stereoisomer forms carbamyl amino acids is provided wherein certain heterocyclic compounds having an assymmetrical carbon, such as 5-substituted hydantoins, are hydrolyzed in the presence of certain enzymes, such as dihydropyrimidinase extracted from calf liver. In another embodiment of the invention, the corresponding amino acids are provided by hydrolyzing the carbamyl amino acids in the presence of these same enzymes.
