Mitochondrial Sulfide Detoxification Requires a Functional Isoform O-Acetylserine(thiol)lyase C in Arabidopsis thaliana [PDF]
, 2012 In non-cyanogenic species, the main source of cyanide derives from ethylene and camalexin biosyntheses. In mitochondria, cyanide is a potent inhibitor of the cytochrome c oxidase and is metabolised by the β-Cyanoalanine synthase CYS-C1, catalysing the ...

Recent Advances in Our Understanding of the Biosynthesis of Sulfur Modifications in tRNAs
Frontiers in Microbiology, 2018 Sulfur is an essential element in all living organisms. In tRNA molecules, there are many sulfur-containing nucleosides, introduced post-transcriptionally, that function to ensure proper codon recognition or stabilization of tRNA structure, thereby ...

Unraveling the role of thiosulfate sulfurtransferase in metabolic diseases [PDF]
, 2020 Thiosulfate sulfurtransferase (TST, EC 2.8.1.1), also known as Rhodanese, is a mitochondrial enzyme which catalyzes the transfer of sulfur in several molecular pathways.

Possible molecular basis of the biochemical effects of cysteine-derived persulfides [PDF]
, 2022 Persulfides (RSSH/RSS−) are species closely related to thiols (RSH/RS−) and hydrogen sulfide (H2S/HS−), and can be formed in biological systems in both low and high molecular weight cysteine-containing compounds.

Evaluation of cysteine metabolism in the rat liver and kidney following intravenous cocaine administration and abstinence [PDF]
, 2021 Many toxic effects of cocaine are attributed to reactive oxygen species (ROS) generated during its metabolism. Recently, it has been suggested that the biological action of ROS is often confused with endogenously generated reactive sulfur species (RSS ...

Sulfane sulfur : new findings on an old topic [PDF]
, 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.
