Summary Gamma-Glutamyl Transpeptidases (y-GTs) are members of the N-terminal nucleophile hydrolase superfamily, enzymes that cleave the y-glutamyl amide bond of glutathione to liberate cysteinylglycine. The released y-glutamyl group can be transferred to water (hydrolysis) or to amino acids or short peptides (transpeptidation). y-GT plays a key role in the gamma glutamyl cycle by regulating the cellular levels of the antioxidant glutathione, hence it is a critical enzyme in maintaining cellular redox homeostasis.y-GT is upregulated during inflammation and in several human tumors, and it is involved in
