General annotation (Comments)

Function

Initiates extracellular glutathione (GSH) breakdown, provides cells with a local cysteine supply and contributes to maintain intracellular 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

A (5-L-glutamyl)-peptide + an amino acid = a peptide + a 5-L-glutamyl amino acid. Ref.22

Glutathione + H2O = L-cysteinylglycine + L-glutamate. Ref.22

Leukotriene C4 + H2O = leukotriene D4 + 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.22

Involvement in disease

Glutathionuria (GLUTH) [MIM:231950]: Autosomal recessive disease.
Note: The disease is caused by mutations affecting the gene represented in this entry.

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.
