A Dinuclear Iron(II) Persulfide Complex Reacts with O 2 to Give Sulfite: Relevance to Persulfide Dioxygenases

Journal of the American Chemical Society
Persulfides (RSSH) have been proposed as key players in biochemical transformations that often involve iron, including iron-sulfur cluster assembly, H2S regulation, post translational modifications, and mitochondrial sulfur oxidation.

Microorganisms uptake zero-valent sulfur via membrane lipid dissolution of octasulfur and intracellular solubilization as persulfide.

Science of the Total Environment
Zero-valent sulfur, commonly utilized as a fertilizer or fungicide, is prevalent in various environmental contexts. Its most stable and predominant form, octasulfur (S8), plays a crucial role in microbial sulfur metabolism, either through oxidation or ...

Investigating the role of regulatory cysteine residues as functional redox switches in human persulfide dioxygenase

2023
Hydrogen sulfide (H2S) regulates many (patho)physiological processes such as inflammation and mitochondrial function, exerting its signaling role in a narrow physiological concentration range, maintained by specialized synthesizing and detoxification enzymes.
