A Narrative Review of the Role of S-Glutathionylation in Bacteria. [PDF]

open access: yesMicroorganisms
Protein glutathionylation is defined as a reversible, ubiquitous post-translational modification, resulting in the formation of mixed disulfides between glutathione and proteins’ cysteine residues. Glutathionylation has been implicated in several cellular mechanisms ranging from protection from oxidative stress to the control of cellular homeostasis ...

Causes and Consequences of Cysteine S-Glutathionylation [PDF]

open access: yesJournal of Biological Chemistry, 2013
Post-translational S-glutathionylation occurs through the reversible addition of a proximal donor of glutathione to thiolate anions of cysteines in target proteins, where the modification alters molecular mass, charge, and structure/function and/or prevents degradation from sulfhydryl overoxidation or proteolysis.

Redox regulation of cell migration via Nischarin S-glutathionylation. [PDF]

open access: yesFree Radic Biol Med
Abstract Reactive oxygen species (ROS) are central players in redox signaling, controlling all biological processes in human health. Many reports demonstrated that ROS play essential roles in regulating cell migration and invasion, while contributing to cancer progression and metastasis, potentially via inducing protein cysteine ...

The effect of oxidant and the non-oxidant alteration of cellular thiol concentration on the formation of protein mixed-disulfides in HEK 293 cells. [PDF]

open access: yesPLoS ONE, 2008
Cellular molecules possess various mechanisms in responding to oxidant stress. In terms of protein responses, protein S-glutathionylation is a unique post-translational modification of protein reactive cysteines forming disulfides with glutathione ...

GSHSite: exploiting an iteratively statistical method to identify s-glutathionylation sites with substrate specificity. [PDF]

open access: yesPLoS ONE, 2015
S-glutathionylation, the covalent attachment of a glutathione (GSH) to the sulfur atom of cysteine, is a selective and reversible protein post-translational modification (PTM) that regulates protein activity, localization, and stability.

S-Glutathionylation Regulates Inflammatory Activities of S100A9 [PDF]

open access: yesJournal of Biological Chemistry, 2010
Reactive oxygen species generated by activated neutrophils can cause oxidative stress and tissue damage. S100A8 (A8) and S100A9 (A9), abundant in neutrophil cytoplasm, are exquisitely sensitive to oxidation, which may alter their functions. Murine A8 is a neutrophil chemoattractant, but it suppresses leukocyte transmigration in the microcirculation ...

S-Glutathionylation in Monocyte and Macrophage (Dys)Function [PDF]

open access: yesInternational Journal of Molecular Sciences, 2013
Atherosclerosis is a chronic inflammatory disease involving the accumulation of monocytes and macrophages in the vascular wall. Monocytes and macrophages play a central role in the initiation and progression of atherosclerotic lesion development. Oxidative stress, which occurs when reactive oxygen species (ROS) overwhelm cellular antioxidant systems ...

High glutathionylation of placental endothelial nitric oxide synthase in preeclampsia

open access: yesRedox Biology, 2019
Decreased nitric oxide (NO) bioavailability plays a critical role in the pathophysiology of preeclampsia (PE). Recent evidence indicates that S-glutathionylation may occur on the endothelial nitric oxide synthase (eNOS), leading to eNOS uncoupling ...
