Identification
Name:	Phenylhydantoin
Description	Phenylhydantoin is a cyclic ureide and it is believed that E. coli may use these compounds as nutrient sources. The gene hyuA codes for d-stereospecific phenylhydantoinase (465 amino acids) which is a homotetramer. This enzyme belongs to the cyclic amidohydrolase superfamily. E. coli D-phenylhydantoinase exhibits a distinct activity toward phenylhydantoin with an aromatic side chain at the 5' position but does not readily hydrolyze the simple cyclic ureides. D-phenylhydantoinase shares a significant homology (>45%) with those of allantoinase and dihydropyrimidinase.
