Intermediates in the Sox sulfur oxidation pathway are bound to a sulfane conjugate of the carrier protein SoxYZ. [PDF]
PLoS ONE, 2017 The Sox pathway found in many sulfur bacteria oxidizes thiosulfate to sulfate. Pathway intermediates are covalently bound to a cysteine residue in the carrier protein SoxYZ.

Is Development of High-Grade Gliomas Sulfur-Dependent?
Molecules, 2014 We characterized γ-cystathionase, rhodanese and 3-mercaptopyruvate sulfurtransferase activities in various regions of human brain (the cortex, thalamus, hypothalamus, hippocampus, cerebellum and subcortical nuclei) and human gliomas with II to IV grade ...

The role of sulfur compounds in chronic obstructive pulmonary disease
Frontiers in Molecular Biosciences, 2022 Chronic obstructive pulmonary disease (COPD) is a common respiratory disease that brings about great social and economic burden, with oxidative stress and inflammation affecting the whole disease progress. Sulfur compounds such as hydrogen sulfide (H2S),

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.

On the possible roles of gaseous sulfur and sulfanes in the atmosphere of Venus
Geophysical Research Letters, 1979 We discuss the possible importance of gaseous elemental sulfur (particularly S2S3 (thiozone) and S4) and sulfanes (H2Sn) in the lower atmosphere of Venus. These species absorb visible and near ultraviolet light. They can provide a local heating source which could drive convection in the 10‐40 km altitude region and may also contribute to the ...

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 ...

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.

Amino Acids, 2010 Mobilization of the L-cysteine sulfur for the persulfuration of the rhodanese of Azotobacter vinelandii, RhdA, can be mediated by the A. vinelandii cysteine desulfurases, IscS and NifS. The amount of cysteine was higher in mutant strains lacking rhdA (MV474) than in wild type. The diazotrophic growth of MV474 was impaired.
