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.

Combined SPME—GC × GC–MS Volatilomics and UHPLC–HRMS Metabolomics Data Fusion Provides a Multidimensional Fingerprinting and Discrimination of White Garlic From the Piacenza Region

Journal of Food Science, Volume 90, Issue 10, October 2025.
ABSTRACT Garlic quality is attributed to a diverse array of volatile and non‐volatile compounds, and several varieties are protected under geographical indication schemes, whereas many typical local cultivars remain chemically uncharacterized. Among them, white garlic from Piacenza (Italy) is a traditional product with recognized sensory attributes. In

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.

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

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 ...

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 ...

Polysulfide and persulfide-mediated activation of the PERK-eIF2α-ATF4 pathway increases Sestrin2 expression and reduces methylglyoxal toxicity

Redox Biology
Unfolded protein response (UPR) is activated in cells under endoplasmic reticulum (ER) stress. One sensor protein involved in this response is PERK, which is activated through its redox-dependent oligomerization.
