CC -!- FUNCTION: Catalyzes the transfer of the gamma-glutamyl moiety of CC glutathione (GSH) and other gamma-glutamyl compounds to amino acids and CC peptides. Major GSH-degrading enzyme, catalyzing the hydrolytic release CC of L-glutamate from GSH. Plays a role in the turnover of the vacuolar CC GSH, serving as an alternative nitrogen source during nitrogen CC starvation. {ECO:0000269|PubMed:11672438}.
