[Term] id: PR:000001351 name: gamma-glutamyltranspeptidase def: "A protein that is the stand alone version of the Gamma-glutamyltranspeptidase (Pfam:PF01019) domain. The functional protein catalyzes the transfer of the gamma-glutamyl moiety of glutathione to an acceptor that may be an amino acid, a peptide or water (forming glutamate), and consists of two polypeptide chains, a heavy and a light subunit, processed from a single chain precursor by an autocatalytic cleavage."
