S-Glutathionylation
S-Glutathionylation is the posttranslational modification of protein cysteine residues by the addition of glutathione, the most abundant and important low-molecular-mass thiol within most cell types.
Protein S-glutathionylation is involved in
- oxidative stress
- nitrosative stress
- preventing irreversible oxidation of protein thiols
- control of cell-signalling pathways by modulating protein function
