Sulfane sulfur – new findings on an old topic
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
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,

Cysteine Metabolism and Oxidative Processes in the Rat Liver and Kidney after Acute and Repeated Cocaine Treatment. [PDF]
The role of cocaine in modulating the metabolism of sulfur-containing compounds in the peripheral tissues is poorly understood. In the present study we addressed the question about the effects of acute and repeated (5 days) cocaine (10 mg/kg i.p ...

Slow generation of hydrogen sulfide from sulfane sulfurs and NADH models [PDF]
Here we report the model studies of the reactions between NADH models (using HEH and BNAH) and sulfane sulfurs (using polysulfides). Such reactions could lead to the oxidation of NADH models and the production of hydrogen sulfide (H2S). Kinetics of the reaction between BNAH and elemental sulfur S8 were determined in ethanol and the second-order rate ...

Sulfur Amino Acids in Diet-induced Fatty Liver: A New Perspective Based on Recent Findings
The relationship of sulfur amino acids to diet-induced fatty liver was established 80 years ago, with cystine promoting the condition and methionine preventing it.

Thiosulfonate‐Derived BODIPY “Stick and Glue” Strategy for Fluorescent Thiol Labeling
We present a powerful photochemical strategy for converting disulfide bonds into stable thioether linkages via a [1,2]‐sigmatropic rearrangement. By integrating this reaction into traditional methanethiosulfonate‐based thiol labeling, we enable light‐triggered stabilization of peptide and protein conjugates with enhanced robustness and versatility ...
