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. An example of the latter is found in the O2-mediated oxidation of glutathione persulfide to sulfite dianion (SO32 ...

Recombinant Escherichia coli with sulfide:quinone oxidoreductase and persulfide dioxygenase rapidly oxidises sulfide to sulfite and thiosulfate via a new pathway

Environmental Microbiology, 2016
Summary Many heterotrophic bacteria contain sulfide:quinone oxidoreductase (SQR) and persulfide dioxygenase (PDO) genes. It is unclear how these enzymes cooperate to oxidise sulfide in bacteria. Cupriavidus pinatubonensis JMP134 contains a gene cluster of

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.
