Glutaredoxins (GRXs) are small proteins that interact with the atypical tripeptide glutathione (GSH), a redox active metabolite that forms a disulfide (GSSG) upon oxidation. GRXs encoding variants of a CPYC motif at a conserved active site act as GSH-dependent thiol-disulfide oxidoreductases (class ...
