Hydantoinase_B

Hydantoinase_B
PFAM accession number:PF02538
Interpro abstract (IPR003692):

An appreciable fraction of the sulphur present in mammals occurs in the form of glutathione. The synthesis of glutathione and its utilization take place by the reactions of the gamma-glutamyl cycle, which include those catalysed by gamma-glutamylcysteine and glutathione synthetases, gamma-glutamyl transpeptidase, cysteinylglycinase, gamma-glutamyl cyclotransferease, and 5-oxoprolinase [ (PUBMED:45011) ].

This domain is found in N-methylhydantoinase B, which converts hydantoin to N-carbamyl-amino acids, and in 5-oxoprolinase EC 3.5.2.9 which catalyses the formation of L-glutamate from 5-oxo-L-proline. These enzymes are part of the oxoprolinase family.

GO function:catalytic activity (GO:0003824)
