Possible Involvement of Hydrosulfide in B12-Dependent Methyl Group Transfer
Molecules, 2017 Evidence from several fields of investigation lead to the hypothesis that the sulfur atom is involved in vitamin B12-dependent methyl group transfer. To compile the evidence, it is necessary to briefly review the following fields: methylation, the new ...

Hydrogen Sulfide Signaling in Plants: Emerging Roles of Protein Persulfidation [PDF]
, 2018 Hydrogen sulfide (H2S) has been largely referred as a toxic gas and environmental hazard, but recent years, it has emerged as an important gas-signaling molecule with effects on multiple physiological processes in both animal and plant systems.

Mammalian frataxin directly enhances sulfur transfer of NFS1 persulfide to both ISCU and free thiols [PDF]
, 2014 Friedreich's ataxia is a severe neurodegenerative disease caused by the decreased expression of frataxin, a mitochondrial protein that stimulates iron sulfur (Fe-S) cluster biogenesis.

Catalase as a sulfide-sulfur oxido-reductase: An ancient (and modern?) regulator of reactive sulfur species (RSS) [PDF]
, 2017 Catalase is well-known as an antioxidant dismutating H2O2 to O2 and H2O. However, catalases evolved when metabolism was largely sulfur-based, long before O2 and reactive oxygen species (ROS) became abundant, suggesting catalase metabolizes reactive ...

Nitrosopersulfide (SSNO(-)) targets the Keap-1/Nrf2 redox system.
Nitric oxide (NO), hydrogen sulfide and polysulfides have been proposed to contribute to redox signaling by activating the Keap-1/Nrf2 stress response system. Nitrosopersulfide (SSNO(-)) recently emerged as a bioactive product of the chemical interaction

Chemical imaging analysis of the brain with X-ray methods [PDF]
, 2017 Cells employ various metal and metalloid ions to augment the structure and the function of proteins and to assist with vital biological processes. In the brain they mediate biochemical processes, and disrupted metabolism of metals may be a contributing ...

Acute hydrogen sulfide-induced neuropathology and neurological sequelae: challenges for translational neuroprotective research. [PDF]
, 2016 Hydrogen sulfide (H2 S), the gas with the odor of rotten eggs, was formally discovered in 1777, over 239 years ago. For many years, it was considered an environmental pollutant and a health concern only in occupational settings. Recently, however, it was

Equilibria between Sulfur Rings in Carbon Disulfide Solution at Elevated Temperatures [PDF]
, 1982 Cyclooctasulfur, S8, dissolved in CS2 reacts at 130-155 °C in sealed ampoules to give S6 and S7 whose concentrations have been determined by HPLC. The half-time of the reaction is independent of the initial S8 concentration and decreases from 232 min at ...
