Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Catalytic component of the GSH degradosomal complex involved in the degradation of glutathione (GSH) and other peptides containing a gamma-glu-X bond. Functions also in a DUG2-DUG3-independent manner as a dipeptidase with high specificity for Cys-Gly and no activity toward tri- or tetrapeptides.
