Hydantoins and ureas derivedfrom α-amino acids are shown to interact with dihydro-orotatedehydrogenasefrom Clostridium(Zymobacterium)oroticum, chiefly as weak competitive inhibitors but that the hydantoinderivedfrom phenylalanine, 5-benzyl-3-(1-carboxy-2-phenylethyl)hydantoin, is a time-dependent irreversible inhibitor of the enzyme. Inhibition experiments with derivatives of this hydantoin and
