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 ...

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.

Coenzyme Q deficiency causes impairment of the sulfide oxidation pathway [PDF]
, 2017 Coenzyme Q (CoQ) is an electron acceptor for sulfide‐quinone reductase (SQR), the first enzyme of the hydrogen sulfide oxidation pathway. Here, we show that lack of CoQ in human skin fibroblasts causes impairment of hydrogen sulfide oxidation ...

Cysteine Signalling in Plant Pathogen Response
Plant, Cell &Environment, Volume 48, Issue 10, Page 7107-7122, October 2025.ABSTRACT The amino acid cysteine is the precursor for a wide range of sulfur‐containing functional molecules in plants, including enzyme cofactors and defence compounds. Due to its redox active thiol group cysteine is highly reactive. Synthesis and degradation pathways are present in several subcellular compartments to adjust the intracellular cysteine

Pichia pastoris Fep1 is a [2Fe-2S] protein with a Zn finger that displays an unusual oxygen-dependent role in cluster binding [PDF]
, 2016 Fep1, the iron-responsive GATA factor from the methylotrophic yeast Pichia pastoris, has been characterised both in vivo and in vitro. This protein has two Cys(2)-Cys(2) type zinc fingers and a set of four conserved cysteines arranged in a Cys-X-5-Cys-X ...

The FASEB Journal, Volume 39, Issue 15, 15 August 2025.Chronic consumption of a western diet suppressed corpus cavernosum cystathionine γ‐lyase (CSE) protein content and H2S production and was associated with elevated penile reactive oxygen species (ROS) levels and impaired erectile function. CSE knockout mice demonstrate impaired erectile function, elevated penile ROS levels, and suppressed corpus ...

Redox Biology, 2018 Hydrogen sulfide (H2S) is a gasotransmitter that regulates cellular homeostasis and impacts on multiple physiological and pathophysiological processes. However, it exerts many of its biological actions indirectly via the formation of H2S-derived sulfane ...

Continuous chemotrophic growth and respiration of Chromatiaceae species at low oxygen concentrations [PDF]
, 1992 Endogenous and maximum respiration rates of nine purple sulfur bacterial strains were determined. Endogenous rates were below 10 nmol O2 · (mg protein · min)-1 for sulfur-free cells and 15–35 nmol O2 · (mg protein · min)-1 for cells containg ...

FEBS Letters, Volume 599, Issue 16, Page 2362-2376, August 2025.Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

Conformational studies on Arabidopsis sulfurtransferase AtStr1 with spectroscopic methods [PDF]
, 2007 Sulfurtransferases/rhodaneses (Str) are enzymes widely distributed in archaea, prokaryota and eukaryota, and catalyze the transfer of sulfur from a donor molecule to a thiophilic acceptor substrate.
