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).
