General annotation (Comments)

Function	Initiates extracellular glutathione (GSH) breakdown, provides cells with a local cysteine supply and contributes to maintain intracelular GSH level. It is part of the cell antioxidant defense mechanism. Catalyzes the transfer of the glutamyl moiety of glutathione to amino acids and dipeptide acceptors. Alternatively, glutathione can be hydrolyzed to give Cys-Gly and gamma glutamate. Isoform 3 seems to be inactive. Ref.7 Ref.22
Catalytic activity	(5-L-glutamyl)-peptide + an amino acid = peptide + 5-L-glutamyl amino acid. Ref.22 Glutathione + H2O = L-cysteinylglycine + L-glutamate. Ref.22
Pathway	Sulfur metabolism; glutathione metabolism.
Subunit structure	Heterodimer composed of the light and heavy chains. The active site is located in the light chain.
Subcellular location	Membrane; Single-pass type II membrane protein.
Tissue specificity	Detected in fetal and adult kidney and liver, adult pancreas, stomach, intestine, placenta and lung. Isoform 3 is lung-specific. There are several other tissue-specific forms that arise from alternative promoter usage but that produce the same protein.
Post-translational modification	N-glycosylated on both chains. Contains hexoses, hexosamines and sialic acid residues. Glycosylation profiles tested in kidney and liver tissues reveal the presence of tissue-specific and site-specific glycan composition, despite the overlap in composition among the N-glycans. A total of 36 glycan compositions, with 40 unique structures are observed. Up to 15 different glycans are observed at a single site, with site-specific variation in glycan composition. The difference in glycosylation profiles in the 2 tissues do not affect the enzyme activity. Ref.13 Ref.14 Ref.19 Ref.20 Ref.21 Ref.22
Involvement in disease	Defects in GGT1 are a cause of glutathionuria (GLUTH) [MIM:231950]; also known as gamma-glutamyltranspeptidase deficiency. It is an autosomal recessive disease.
Miscellaneous	Cys-454 was thought to bind the gamma-glutamyl moiety, but mutagenesis of this residue had no effect on activity.
Sequence similarities	Belongs to the gamma-glutamyltransferase family.
Sequence caution	The sequence AAA35899.1 differs from that shown. Reason: Erroneous initiation.
