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 ...

Glutaredoxin 1 protects lens epithelial cells from epithelial-mesenchymal transition by preventing casein kinase 1α S-glutathionylation during posterior capsular opacification

open access: yesRedox Biology, 2023
Oxidative stress drives protein S-glutathionylation, which regulates the structure and function of target proteins and is implicated in the pathogenesis of many diseases.

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.

Fluorescein-labeled glutathione to study protein S-glutathionylation [PDF]

open access: yesAnalytical Biochemistry, 2010
Numerous studies of S-glutathionylation of cysteine thiols indicate that this protein modification plays a key role in redox regulation of proteins. To facilitate the study of protein S-glutathionylation, we developed a synthesis and purification to produce milligram quantities of fluorescein-labeled glutathione.

In Vivo Tagging and Characterization of S‐Glutathionylated Proteins by a Chemoenzymatic Method [PDF]

open access: yesAngewandte Chemie, 2012
Glutathione (GSH), a sulfhydryl-containing tripeptide present in most organisms at millimolar levels, plays a crucial role in redox homeostasis.1 Reactive cysteine residues are vulnerable to reactive oxygen or nitrogen species and thus depend heavily on GSH to avoid irreversible oxidation.[1a], [2] Reversible conjugation of GSH to proteins through the ...

S-glutathionylation proteome profiling reveals a crucial role of a thioredoxin-like protein in interspecies competition and cariogenecity of Streptococcus mutans.

open access: yesPLoS Pathogens, 2020
S-glutathionylation is an important post-translational modification (PTM) process that targets protein cysteine thiols by the addition of glutathione (GSH).

Protein thiyl radical mediates S-glutathionylation of complex I [PDF]

open access: yesFree Radical Biology and Medicine, 2012
Complex I is a critical site of O(2)(•-) production and the major host of reactive protein thiols in mitochondria. In response to oxidative stress, complex I protein thiols at the 51- and 75-kDa subunits are reversibly S-glutathionylated. The mechanism of complex I S-glutathionylation is mainly obtained from insight into GSSG-mediated thiol-disulfide ...

New insights into posttranslational modifications of proteins during bull sperm capacitation

open access: yesCell Communication and Signaling, 2023
Background Due to the unique nature of spermatozoa, which are transcriptionally and translationally silent, the regulation of capacitation is based on the formation of posttranslational modifications of proteins (PTMs).
