Deglutathionylation
WebMar 1, 2009 · This catalysis of deglutathionylation is performed much more efficiently by GRXs than by other disulfide oxidoreductases such as TRXs or protein disulfide isomerases (Jung and Thomas, 1996; Zaffagnini et al., 2008). GRXs have also been suggested to play a role in the catalysis of glutathionylation (Starke et al., 2003; Beer et al., 2004).
