Glutathione hydrolase ( EC 3.4.19.13, glutathionase, GGT, gamma-glutamyltranspeptidase) is an enzyme. [1] [2] [3] [4] [5] [6] [7] This enzyme catalyses the following chemical reaction

glutathione + H2O L-cysteinylglycine + L- glutamate

This protein also acts as enzyme EC 2.3.2.2 (gamma-glutamyltransferase).
