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

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

The conversion of H2S to sulfane sulfur [PDF]
Nature 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”.

Sulfane sulfur – new findings on an old topic
Acta 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 ...

3-Mercaptopyruvate sulfurtransferase: an enzyme at the crossroads of sulfane sulfur trafficking
Biological Chemistry, 2020 Abstract 3-Mercaptopyruvate sulfurtransferase (MPST) catalyzes the desulfuration of 3-mercaptopyruvate to generate an enzyme-bound hydropersulfide. Subsequently, MPST transfers the persulfide’s outer sulfur atom to proteins or small molecule acceptors. MPST activity is known to be involved in hydrogen sulfide generation, tRNA thiolation,
