LITERATURE
glutathionylation
-
Cys269 of IDPc is a target for S-glutathionylation, this modification is reversed by dithiothreitol as well as enzymatically by cytosolic glutaredoxin in the presence of glutathione. Glutathionylated IDPc is significantly less susceptible than native protein to peptide fragmentation by reactive oxygen species and proteolytic digestion. Glutathionylation may play a protective role in the degradation of protein through the structural alterations of IDPc.
