ChaC

ChaC
PFAM accession number:PF04752
Interpro abstract (IPR006840):

The ChaC family of proteins function as gamma-glutamyl cyclotransferases acting specifically to degrade glutathione but not other gamma-glutamyl peptides [ (PUBMED:23070364) (PUBMED:25716890) ]. It is is conversed across all phyla and represents a new pathway for glutathione degradation in living cells.

GO process:glutathione catabolic process (GO:0006751)
GO function:gamma-glutamylcyclotransferase activity (GO:0003839)
