Total sulfane sulfur bioavailability reflects ethnic and gender disparities in cardiovascular disease. [PDF]

open access: yesRedox Biol, 2018
Hydrogen sulfide (H2S) has emerged as an important physiological and pathophysiological signaling molecule in the cardiovascular system influencing vascular tone, cytoprotective responses, redox reactions, vascular adaptation, and mitochondrial respiration.

Oxidative Stress and Iron Addiction: A Comparative Study of 1321N1 Astrocytoma and T98G Glioblastoma Cells with Differential Expression of L-Cysteine-Metabolizing Enzymes [PDF]

open access: yesBiomolecules
Gliomas are central nervous system primary tumors that are distinguished by heterogeneity, broad-based infiltration, and metabolic reprogramming that sustains proliferation, invasion, and therapy refractoriness.

In Hyphomicrobium denitrificans Two Related Sulfane-Sulfur Responsive Transcriptional Repressors Regulate Thiosulfate Oxidation and Have a Deep Impact on Nitrate Respiration and Anaerobic Biosyntheses. [PDF]

open access: yesMol Microbiol
In Hyphomicrobium denitrificans, the use of thiosulfate as a supplemental electron donor is regulated by two homologous sulfane‐sulfur responsive ArsR‐type transcriptional repressors, sHdrR and SoxR, that act cooperatively. Remarkably, the regulation by sHdrR/SoxR extends far beyond sulfur oxidation and deeply affects anaerobic metabolism, particularly

Synechococcus sp. PCC7002 Uses Peroxiredoxin to Cope with Reactive Sulfur Species Stress

open access: yesmBio, 2022
Cyanobacteria are a widely distributed group of microorganisms in the ocean, and they often need to cope with the stress of reactive sulfur species, such as sulfide and sulfane sulfur.

Intranasal administration of polysulfide prevents neurodegeneration in spinal cord and rescues mice from delayed paraplegia after spinal cord ischemia

open access: yesRedox Biology, 2023
Background: Delayed paraplegia is a devastating complication of thoracoabdominal aortic surgery. Hydrogen sulfide (H2S) was reported to be protective in a mouse model of spinal cord ischemia and the beneficial effect of H2S has been attributed to ...

Isotope dilution mass spectrometry for the quantification of sulfane sulfurs [PDF]

open access: yesFree Radical Biology and Medicine, 2014
Sulfane sulfurs are one type of important reactive sulfur species. These molecules have unique reactivity that allows them to attach reversibly to other sulfur atoms and exhibit regulatory effects in diverse biological systems. Recent studies have suggested that sulfane sulfurs are involved in signal transduction processes regulated by hydrogen sulfide

Sulfane Sulfur Compounds as Source of Reappearance of Reductive Off-Odors in Wine

open access: yesFermentation, 2022
Reactive compounds with one or more sulfane sulfur atoms can be an important source of reductive off-odors in wine. These substances contain labile sulfur, which can participate in microbiological (enzymatic) and chemical transformations (including in ...

Sulfane sulfur – new findings on an old topic

open access: yesActa Biochimica Polonica, 2019
Sulfane sulfur is a divalent sulfur atom bonded to another sulfur which is very reactive and labile. Compounds containing this reactive sulfur include persulfides, polysulfides, thiosulfate, thiosulfinates, polythionates, and elemental sulfur. Sulfane sulfur appears in a number of biologically important compounds, including thiocysteine, thiocystine ...

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 ...

The conversion of H2S to sulfane sulfur [PDF]

open access: yesNature Reviews Molecular Cell Biology, 2012
In a recently published Review article (H2S signalling through protein sulfhydration and beyond. Nature Rev. Mol. Cell Biol. 13, 499–507 (2012))1, Paul and Snyder use the term 'sulfhydration' to define a protein modification involving hydrogen sulfide (H2S) in which “the sulfhydryl group of a reactive Cys is modified to an -SSH group”.
