gamma-Glutamyl transpeptidase catalyzes transfer of the gamma-glutamyl moiety of glutathione to amino acids, dipeptides, and to glutathione itself; the enzyme also catalyzes the hydrolysis of glutathione to glutamate and cysteinyl-glycine. This review deals with the tissue distribution and localization of
