CC -!- FUNCTION: Catalyzes the transfer of the gamma-glutamyl moiety of CC glutathione (GSH) and other gamma-glutamyl compounds to amino CC acids and peptides. Major GSH-degrading enzyme, catalyzing the CC hydrolytic release of L-glutamate from GSH. Plays a role in the CC turnover of the vacuolar GSH, serving as an alternative nitrogen CC source during nitrogen starvation. CC -!- CATALYTIC ACTIVITY: A (5-L-glutamyl)-peptide + an amino acid = a CC peptide + a 5-L-glutamyl amino acid. CC -!- CATALYTIC ACTIVITY: Glutathione + H(2)O = L-cysteinylglycine + L- CC glutamate. CC -!- ENZYME REGULATION: Activity is decreased by glutathione and CC ammonium ion. CC -!- PATHWAY: Sulfur metabolism; glutathione metabolism. CC -!- SUBUNIT: Heterodimer composed of a light and a heavy chain. The CC active site is located in the light chain (By similarity). CC -!- SUBCELLULAR LOCATION: Vacuole membrane; Single-pass type II CC membrane protein. CC -!- INDUCTION: Induced upon nitrogen starvation. Repressed by ammonium CC ions. 6-diazo-5-oxo-L-norleucine and L-azaserine are irreversible CC inhibitors whereas serine-borate is a reversible inhibitor. CC -!- PTM: Cleaved by autocatalysis into a large and a small subunit. CC -!- MISCELLANEOUS: Present with 672 molecules/cell in log phase SD CC medium. CC -!- SIMILARITY: Belongs to the gamma-glutamyltransferase family.
