ENZYME entry: EC 4.3.2.8

Accepted Name
gamma-glutamylamine cyclotransferase
Reaction catalysed
epsilon-(gamma-L-glutamyl)-L-lysine <=> 5-oxo-L-proline + L-lysine
Comment(s)
  • The enzyme, found in vertebrates, has no activity toward alpha- (gamma-L-glutamyl)-L-amino acids (cf. EC 4.3.2.9).
  • The enzyme acts as a cyclotransferase, cleaving the amide bond via transamidation using the alpha-amine of the gamma-L-glutamyl residue, releasing it as the cyclic 5-oxo-L-proline.
