ENZYME entry: EC 4.3.2.9

Accepted Name
Gamma-glutamylcyclotransferase.
Alternative Name(s)
GGCT.
Reaction catalysed
Alpha-(gamma-L-glutamyl)-L-amino acid <=> alpha-L-amino acid + 5-oxo-L-proline
Comment(s)
  • The enzyme, found in animals and plants, acts on derivatives of L-glutamate, L-2-aminobutanoate, L-alanine and glycine.
  • The enzyme acts as a cyclotransferase, cleaving the amide bond via transamidation using the alpha-amine of the L-glutamyl residue, releasing it as the cyclic 5-oxo-L-proline.
  • Formerly EC 2.3.2.4.
