S-glutathionylation modification of proteins and the association with cellular death (Review)
S-glutathionylation (SSG), a redox-sensitive post-translational modification mediated by glutathione, regulates protein structure and function through reversible disulfide bond formation at cysteine residues. Glutaredoxins (GRXs), pivotal antioxidant enzymes, catalyze SSG dynamics to maintain thiol homeostasis.

Mitochondria are critical sources of hydrogen peroxide (H2O2), an important secondary messenger in mammalian cells. Recent work has shown that O2•-/H2O2 emission from individual sites of production in mitochondria is regulated by protein S ...

Abstract Glycine is a dispensable and functional amino acid that promotes fish growth, however, the optimal glycine content in fish diets is not known. This study assessed the effect of dietary glycine content on growth, feed utilization, and antioxidant capacity of large yellow croaker (LYC) Larimichthys crocea.

Actin S-glutathionylation: evidence against a thiol-disulphide exchange mechanism
Many proteins, including actin, are targets for S-glutathionylation, the reversible formation of mixed disulphides between protein cysteinyl thiol groups and glutathione (GSH) that can be induced in cells by oxidative stress.

S-Glutathionylation: Indicator of Cell Stress and Regulator of the Unfolded Protein Response [PDF]
The specific posttranslational modification of protein cysteine residues by the addition of the tripeptide glutathione is termed S-glutathionylation. This process is promoted by oxidative and nitrosative stress but also occurs in unstressed cells. Altered levels of S-glutathionylation in some proteins have been associated with numerous pathologies ...

Serum Levels of S-Glutathionylated Proteins as a Risk-Marker for Arteriosclerosis Obliterans
Oxidative stress plays a role in the development of chronic peripheral arterial disease (PAD) because under these conditions redox regulation is impaired, inducing the S-glutathionylation of proteins. A method of estimating the levels of S-glutathionylated proteins has been developed using biotinylated glutathione S-transferase, which allows the study ...

Protein phosphatase PP2Cα S-glutathionylation regulates cell migration
Redox signaling is a fundamental mechanism that controls all major biological processes partly via protein cysteine oxidations, including S-glutathionylation. Despite over 2000 cysteines identified to form S-glutathionylation in databases, the identification of redox cysteines functionally linked to a biological process of interest remains challenging.

S-glutathionylation of buccal cell proteins as biomarkers of exposure to hydrogen peroxide
Exogenous or endogenous hydrogen peroxide (H2O2) is a reactive oxygen species (ROS) that can lead to oxidation of cellular nucleophiles, particularly cysteines in proteins. Commercial mouthwashes containing H2O2 provide the opportunity to determine clinically whether changes in S-glutathionylation of susceptible proteins in buccal mucosa cells can be ...
