mBioMethanethiol (MT) is a sulfur-containing compound produced during dimethylsulfoniopropionate (DMSP) degradation by marine bacteria. The C–S bond of MT can be cleaved by methanethiol oxidases (MTOs) to release a sulfur atom.

Sulfur Atom in its Bound State Is a Unique Element Involved in Physiological Functions in Mammals
Molecules, 2016 It was in the 1950s that the term polysulfide or persulfide was introduced in biological studies. The unfamiliar term “sulfane sulfur” sometimes appeared in papers published in the 1970s, and was defined in the review article by Westley in 1983.

Modified cyclodextrins solubilize elemental sulfur in water and enable biological sulfane sulfur delivery. [PDF]
Chem Sci, 2020 An important form of biological sulfur is sulfane sulfur, or S0, which is found in polysulfide and persulfide compounds as well as in elemental sulfur. Sulfane sulfur, often in the form of S8, functions as a key energy source in the metabolic processes ...

In the Alphaproteobacterium Hyphomicrobium denitrificans SoxR Serves a Sulfane Sulfur-Responsive Repressor of Sulfur Oxidation. [PDF]
Antioxidants (Basel), 2023 In organisms that use reduced sulfur compounds as alternative or additional electron donors to organic compounds, transcriptional regulation of genes for enzymes involved in sulfur oxidation is needed to adjust metabolic flux to environmental conditions.

On the chemical biology of the nitrite/sulfide interaction [PDF]
, 2015 Sulfide (H2S/HS(-)) has been demonstrated to exert an astounding breadth of biological effects, some of which resemble those of nitric oxide (NO). While the chemistry, biochemistry and potential (patho)physiology of the cross-talk between sulfide and NO ...

New fluorescent probes for sulfane sulfurs and the application in bioimaging [PDF]
, 2013 A sulfane sulfur mediated benzodithiolone formation was developed. Based on this reaction, two fluorescent probes ( and ) for the detection of sulfane sulfur species (persulfide, polysulfide, and elemental sulfur) were prepared and evaluated.
