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 ...

Cysteine Metabolism and Oxidative Processes in the Rat Liver and Kidney after Acute and Repeated Cocaine Treatment. [PDF]

open access: yesPLoS ONE, 2016
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 ...

Reactive Sulfur Species Interact with Other Signal Molecules in Root Nodule Symbiosis in Lotus japonicus

open access: yesAntioxidants, 2020
Reactive sulfur species (RSS) function as strong antioxidants and are involved in various biological responses in animals and bacteria. Few studies; however, have examined RSS in plants.

3-Mercaptopyruvate sulfurtransferase: an enzyme at the crossroads of sulfane sulfur trafficking

open access: yesBiological 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,

Sulfur Amino Acids in Diet-induced Fatty Liver: A New Perspective Based on Recent Findings

open access: yesMolecules, 2014
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.

Slow generation of hydrogen sulfide from sulfane sulfurs and NADH models [PDF]

open access: yesBioorganic & Medicinal Chemistry Letters, 2017
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 ...

Cars2‐Mediated Cysteine Catabolism Drives Brown Fat Development and Thermogenesis Through Persulfidating EBF2

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
We demonstrate that Cars2, a cysteine catabolic enzyme in mouse iBAT, is critical for cold tolerance and brown adipocyte differentiation. Through its CPERS activity, Cars2 produces CysSSH/H2S to induce EBF2 persulfidation, promoting its interaction with PPARγ and BRG1 to enhance thermogenic gene expression.

Thiosulfonate‐Derived BODIPY “Stick and Glue” Strategy for Fluorescent Thiol Labeling

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
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 ...

Yohimbine Alleviates Oxidative Stress and Suppresses Aerobic Cysteine Metabolism Elevated in the Rat Liver of High-Fat Diet-Fed Rats

open access: yesMolecules, 2023
Yohimbine is a small indole alkaloid derived from the bark of the yohimbe tree with documented biological activity, including anti-inflammatory, erectile dysfunction relieving, and fat-burning properties.

Synthesis of (E)‐β‐SF5‐Styrenes via a Heck Reaction of in situ Generated Vinylsulfur Pentafluoride†

open access: yesChinese Journal of Chemistry, Volume 44, Issue 11, Page 1823-1827, 1 June 2026.
A Heck cross‐coupling reaction between aryl(hetero)iodides and in situ generated vinylsulfur pentafluoride is reported. This reaction provides β‐SF5‐styrenes in one‐step as a single (E)‐stereoisomer and tolerates a broad range of functional groups. Comprehensive Summary The synthesis of (E)‐(1‐alken‐1‐yl)pentafluoro‐λ6‐sulfanes, a valuable class of ...
