General annotation (Comments)
| Function | Initiates extracellular glutathione (GSH) breakdown, provides cells with a local cysteine supply and contributes to maintain intracelular GSH level. It is part of the cell antioxidant defense mechanism. Catalyzes the transfer of the glutamyl moiety of glutathione to amino acids and dipeptide acceptors. Alternatively, glutathione can be hydrolyzed to give Cys-Gly and gamma glutamate. Ref.1 |
| Catalytic activity | (5-L-glutamyl)-peptide + an amino acid = peptide + 5-L-glutamyl amino acid. |
| Pathway | |
| Subunit structure | Heterodimer composed of the light and heavy chains. The active site is located in the light chain By similarity. |
| Subcellular location | Membrane; Single-pass type II membrane protein Potential. |
| Induction | Induced upon nitrogen starvation. Also induced by non-fermentable carbon sources such as glycerol, acetate and ethanol in a pap1-independent manner. Ref.3 |
| Sequence similarities | Belongs to the gamma-glutamyltransferase family. |
