Abstract:
Bacterial dihydropyrimidinase was shown to catalyze the hydrolytic cleavage of various 5-substituted hydantoins to the corresponding N-carbamyl-D-amino acids under alkaline conditions. Therefore, an enzymatic method for preparing the D-forms of phenylglycine-related amino acids was developed using immobilized bacterial cells with high enzyme activity. Alkalophilic bacteria were a good enzyme source for this process. The process is simple and economical for use in the production of various amino acids with the D-configuration.
