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

Acceleration of Anaerobic Cysteine Transformations to Sulfane Sulfur Consequent to γ-Glutamyl Transpeptidase Inhibition

The Scientific World Journal, 2012
Toxicity of drugs and radiation in the cells is largely dependent on the level of thiols. In the present studies, an attempt has been made to inhibit γ-glutamyl transpeptidase (γGT) activity in EAT-bearing animals tissue.

Hydrogen Sulfide Protects Erectile Function Through Stimulation of Antioxidant Defense in the Corpus Cavernosum: Insights From SG1002 Administration and Cystathionine γ‐Lyase Knockout

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 ...

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.

Mycobacterium tuberculosis sulfurtransferase SseA is activated by its neighboring gene product Rv3284

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.

Sulfide Quinone Oxidoreductase Alleviates Acute Ulcerative Colitis by Regulating Mitochondrial Dysfunction

MedComm, Volume 6, Issue 7, July 2025.
SQOR deficiency in intestinal epithelial cells aggravated DSS‐induced acute colitis and disrupted the integrity of intestinal tight junctions. Moreover, SQOR plays a vital role in regulating the mitochondrial function of intestinal epithelial cells.

Rhodobacteraceae methanethiol oxidases catalyze methanethiol degradation to produce sulfane sulfur other than hydrogen sulfide

mBio
Methanethiol (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.

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 ...

Mobilization of sulfane sulfur from cysteine desulfurases to the Azotobacter vinelandii sulfurtransferase RhdA

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.
