Persulfidation of DJ-1: Mechanism and Consequences

open access: yesBiomolecules, 2022
DJ-1 (also called PARK7) is a ubiquitously expressed protein involved in the etiology of Parkinson disease and cancers. At least one of its three cysteine residues is functionally essential, and its oxidation state determines the specific function of the

Cysteine trisulfide oxidizes protein thiols and induces electrophilic stress in human cells

open access: yesRedox Biology, 2021
The cellular effects of hydrogen sulfide (H2S) signaling may be partially mediated by the formation of alkyl persulfides from thiols, such as glutathione and protein cysteine residues.

Saccharomyces cerevisiae Rhodanese RDL2 Uses the Arg Residue of the Active-Site Loop for Thiosulfate Decomposition

open access: yesAntioxidants, 2021
Persulfide, polysulfide and thiosulfate are examples of sulfane sulfur containing chemicals that play multiple functions in biological systems. Rhodaneses are widely present in all three kingdoms of life, which catalyze sulfur transfer among these ...

Protein Persulfidation in Plants: Function and Mechanism [PDF]

open access: yesAntioxidants, 2021
As an endogenous gaseous transmitter, the function of hydrogen sulfide (H2S) has been extensively studied in plants. Once synthesized, H2S may be involved in almost all life processes of plants. Among them, a key route for H2S bioactivity occurs via protein persulfidation, in which process oxidizes cysteine thiol (R-SH) groups into persulfide (R-SSH ...

Possible molecular basis of the biochemical effects of cysteine-derived persulfides

open access: yesFrontiers in Molecular Biosciences, 2022
Persulfides (RSSH/RSS−) are species closely related to thiols (RSH/RS−) and hydrogen sulfide (H2S/HS−), and can be formed in biological systems in both low and high molecular weight cysteine-containing compounds.

Contribution of NRF2 to sulfur metabolism and mitochondrial activity

open access: yesRedox Biology, 2023
NF-E2-related factor 2 (NRF2) plays a crucial role in the maintenance of cellular homeostasis by regulating various enzymes and proteins that are involved in the redox reactions utilizing sulfur.

Persulfides and the cellular thiol landscape [PDF]

open access: yesProceedings of the National Academy of Sciences, 2014
The biochemistry of sulfur touches on every aspect of cellular biology, from protein structure and function to redox regulation to defense against chemical stress. Over the last decade, posttranslational modification of protein thiols by reactive oxygen or nitrogen species has emerged as a major component of signal transduction, leading to both ...
