Glutationska hidrolaza
Glutationska hidrolaza (EC 3.4.19.13, glutationaza, GGT, gama-glutamiltranspeptidaza) je enzim.[1][2][3][4][5][6][7] Ovaj enzim katalizuje sledeću hemijsku reakciju
- glutation + H2O L-cisteinilglicin + L-glutamat
Ovaj protein takođe deluje kao enzim EC 2.3.2.2 (gama-glutamiltransferaza).
