ECMDB: D-phenylhydantoinase (Q46806)

Identification

Name:

D-phenylhydantoinase

Synonyms:

Hydantoin-utilizing enzyme hyuA

Gene Name:

hyuA

Enzyme Class:

3.5.2.2

Biological Properties

General Function:

Involved in hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in cyclic amides

Specific Function:

Catalyzes the stereospecific hydrolysis of the cyclic amide bond of D-hydantoin derivatives with an aromatic side chains at the 5'-position. Has no activity on dihydropyrimidines. The physiological function is unknown
