ID   4.3.2.8
DE   gamma-glutamylamine cyclotransferase.
CA   epsilon-(gamma-L-glutamyl)-L-lysine = 5-oxo-L-proline + L-lysine.
CC   -!- The enzyme, found in vertebrates, has no activity toward alpha-
CC       (gamma-L-glutamyl)-L-amino acids (cf. EC 4.3.2.9).
CC   -!- The enzyme acts as a cyclotransferase, cleaving the amide bond via
CC       transamidation using the alpha-amine of the gamma-L-glutamyl residue,
CC       releasing it as the cyclic 5-oxo-L-proline.
