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).

Formation, Reactivity, and Detection of Protein Sulfenic Acids [PDF]

Chemical Research in Toxicology, 2010
It has become clear in recent decades that the post-translational modification of protein cysteine residues is a crucial regulatory event in biology. Evidence supports the reversible oxidation of cysteine thiol groups as a mechanism of redox-based signal transduction, while the accumulation of proteins with irreversible thiol oxidations is a hallmark ...

Molecular Mechanisms and Therapeutic Potential of DJ‐1 in Skeletal Muscle Homeostasis and Disease

Comprehensive Physiology, Volume 16, Issue 1, February 2026.
DJ‐1 protein functions as a redox‐sensing guardian in skeletal muscle by coordinating antioxidant defense, mitochondrial homeostasis, metabolic adaptation, and anti‐atrophy signaling. Enhancing its function holds promise as a potential therapeutic strategy for muscle atrophy, ALS, and metabolic myopathies.

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 (

Redox regulation of cell proliferation: Bioinformatics and redox proteomics approaches to identify redox-sensitive cell cycle regulators

, 2018
Plant stem cells are the foundation of plant growth and development. The balance of quiescence and division is highly regulated, while ensuring that proliferating cells are protected from the adverse effects of environment fluctuations that may damage ...

Parameters Influencing the Plasma‐Mediated Inactivation of Microorganisms and Viruses in Wastewater

Plasma Processes and Polymers, Volume 23, Issue 2, February 2026.
Wastewater parameters, e.g., chemical oxygen demand (COD), influences the antimicrobial and antiviral efficacy of plasma. ABSTRACT Pathogenic microorganisms and viruses in water pose an environmental risk demanding for effective remediation tools like physical plasma. However, parameters influencing its efficiency are mostly descriptive.

OhsR acts as an organic peroxide-sensing transcriptional activator using an S-mycothiolation mechanism in Corynebacterium glutamicum

Microbial Cell Factories, 2018
Background Corynebacterium glutamicum is a well-known producer of various l-amino acids in industry. During the fermenting process, C. glutamicum unavoidably encounters oxidative stress due to a specific reactive oxygen species (ROS) produced by ...

The formation of cysteine-tyrosine crosslinks via a sulfenic acid intermediate [abstract] [PDF]

, 2008
only availableCysteine residues in proteins are readily oxidized to sulfenic acids. Sulfenic acids, in turn, can act as potent electrophiles that have been observed to form intrastrand protein crosslinks with neighboring amide or cysteine residues ...
