Increased intracellular H2S levels enhance iron uptake in Escherichia coli [PDF]

mBio
We investigated the impact of intracellular hydrogen sulfide (H2S) hyperaccumulation on the transcriptome of Escherichia coli. The wild-type (WT) strain overexpressing mstA, encoding 3-mercaptopyruvate sulfur transferase, produced significantly higher ...

Oxidants induce Escherichia coli MarR glutathionylation in the presence of glutathione [PDF]

Redox Biology
The results of protein thiols reacting with oxidants may be different in the presence or absence of glutathione (GSH). Upon exposure to oxidants, such as Cu2+ and polysulfide, the multiple drug resistant regulator MarR dimer in Escherichia coli is ...

Unique response of polysulfide in serum albumin to oxidative stress [PDF]

Scientific Reports
Supersulfide species have been identified as molecules that have catenated sulfur atoms as persulfides (R-SSH) and polysulfides (R-SSnH). The physiological activities of intracellular supersulfides have been widely studied, but little is known about the ...

The Therapeutic Potential of Supersulfides in Oxidative Stress-Related Diseases. [PDF]

Biomolecules
Oxidation-reduction (redox) reactions are fundamental to sustaining life, with reactive oxygen and nitrogen species playing pivotal roles in cellular signaling and homeostasis. However, excessive oxidative stress disrupts redox balance, contributing to a wide range of diseases, including inflammatory and pulmonary disorders, neurodegeneration, and ...

The Selective 3-MST Inhibitor I3MT-3 Works as a Potent Caspase-1 Inhibitor. [PDF]

Int J Mol Sci
I3MT-3 (HMPSNE) has been identified as a selective inhibitor of the supersulfide-producing enzyme 3-MST. In this study, we found that I3MT-3 inhibits inflammatory responses, including the secretion of the pro-inflammatory cytokine interleukin-1β (IL-

A Theoretical Discussion on the Stability of (O2) and (S2) Species in KCl and KBr Salts: Luminescence Spectra and Defect Energy Formation

, 2022
In this article, we unambiguously demonstrate from first-principles calculations that superoxide (O2)− and supersulfide (S2)− anions play the role of luminescence centers in chalcogen-doped potassium halides.

Role of Sulfide Quinone Oxidoreductase and Supersulfides in Hepatic Ischemia-Reperfusion Injury in Mice. [PDF]

Antioxidants (Basel)
Hepatic ischemia–reperfusion injury (IRI) is a critical clinical condition associated with liver transplantation and acute liver injury. This study investigated the role of sulfide quinone oxidoreductase (SQOR) and its downstream product, supersulfides, in hepatic IRI.
