Cytoplasmic sulfurtransferases in the purple sulfur bacterium Allochromatium vinosum: evidence for sulfur transfer from DsrEFH to DsrC. [PDF]

PLoS ONE, 2012
While the importance of sulfur transfer reactions is well established for a number of biosynthetic pathways, evidence has only started to emerge that sulfurtransferases may also be major players in sulfur-based microbial energy metabolism.

Therapeutic Gases in Biomedicine: Updates on Nitric Oxide and Beyond

Advanced Science, Volume 13, Issue 23, 23 April 2026.
Therapeutic gases, including NO, CO, H2S, H2, CO2, O2, and Xe, play vital roles in cellular signaling and repair. This review highlights the emerging carriers and delivery systems that enable controlled, localized gas release for diagnostic and therapeutic applications.

Cysteine-based redox regulation and signalling in plants

Frontiers in Plant Science, 2013
Living organisms are subjected to oxidative stress conditions which are characterized by the production of reactive oxygen (ROS), nitrogen (RNS) and sulfur (RSS) species.

Clonal Stabilization Reveals a DAO/3MST‐Expressing MDCK Subpopulation With Robust d‐Cysteine‐Mediated H2S Production

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
A subpopulation of MDCK (NBL‐2) cells, an epithelial cell line derived from the normal kidney, expresses DAO and 3MST. The DAO/3MST‐expressing cells are progressively eliminated during passaging; however, clonal isolation enables the establishment of sublines that maintain stable H2S production. Clonal cells co‐expressing DAO and 3MST therefore provide

Redox Signaling Regulated by Cysteine Persulfide and Protein Polysulfidation

Molecules, 2016
For decades, reactive persulfide species including cysteine persulfide (CysSSH) have been known to exist endogenously in organisms. However, the physiological significance of endogenous persulfides remains poorly understood. That cystathionine β-synthase

NFS1 Regulates IDH2 to Attenuate Abdominal Aortic Aneurysms via Interacting With SP2

Advanced Science, Volume 13, Issue 14, 9 March 2026.
The loss of NFS1 leads to its reduced binding with the transcription factor SP2, resulting in decreased expression of the downstream gene Idh2. This causes a shift in energy supply toward glycolysis in VSMCs, ultimately contributing to the occurrence and progression of AAA.

Iron‐Based Materials for Advanced Lithium/Sodium‐Ion Batteries

ChemSusChem, Volume 19, Issue 4, 25 February 2026.
This Review examines iron‐based anode materials for lithium‐ and sodium‐ion batteries, emphasizing how phase chemistry (sulfides, oxides, and metal–organic framework (MOF)‐derived compounds), multiscale structural engineering, and interface regulation collectively address volume expansion, conductivity limitations, and cycling instability, while ...

Ultrasensitive bioorthogonal probes for selective discrimination of trace H2S2/H2Sn in sulfide-competitive contexts

Acta Pharmaceutica Sinica B
Hydrogen persulfide/polysulfides (H2S2/H2Sn), as an oxidized derivative of hydrogen sulfide (H2S), is capable of directly inducing the S-persulfidation of cysteine residues, thereby modulating the activity of relevant enzymes.

Reaction of peroxynitrite with thiols, hydrogen sulfide and persulfides

Redox Biochemistry and Chemistry
Three decades of research on the biochemistry of peroxynitrite (ONOOH/ONOO−) have established that this stealthy oxidant is formed in biological systems, and that its main targets are carbon dioxide (CO2), metalloproteins and thiols (RSH).

Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Oxidative stress occurs when the reactive oxygen species (ROS) production overwhelms the ROS scavenging, which lead to genomic instability, epigenetic regulation, proteostasis imbalance, and lipid peroxidation, subsequently causing the occurrence and development of numerous diseases. ABSTRACT Although the physiological level of reactive oxygen species (
