Isolation, purification and characteristics of D-hydantoinase were carried out. The experiment results showed that the optimal pH and temperature of pure D-hydantoinase were pH 8. 5 and 35℃, respectively. D-hydantoinase activity could be increased significantly by Mn〓 and Fe〓. Substrate specificity of D-hydantoinase on various hydantoin derivatives showed the optimal substrate of D-hydantoinase was 5-phenylhydantoin, but hydantoin, 5-methylthioehylhydantoin, 5-hydroxyphenylhydantoin, 5-methylhydantoin, 5-benzylhydantoin could also be hydrolyzed by D-hydantoinase.
