Structure of the respiratory MBS complex reveals iron-sulfur cluster catalyzed sulfane sulfur reduction in ancient life. [PDF]
Nat Commun, 2020 AbstractModern day aerobic respiration in mitochondria involving complex I converts redox energy into chemical energy and likely evolved from a simple anaerobic system now represented by hydrogen gas-evolving hydrogenase (MBH) where protons are the terminal electron acceptor.

Mass spectrometric identification of intermediates in the O2-driven [4Fe-4S] to [2Fe-2S] cluster conversion in FNR [PDF]
, 2017 The iron-sulfur cluster containing protein FNR is the master regulator for the switch between anaerobic and aerobic respiration in Escherichia coli and many other bacteria. The [4Fe-4S] cluster functions as the sensory module, undergoing reaction with O2

Isotope dilution mass spectrometry for the quantification of sulfane sulfurs [PDF]
Free Radical Biology and Medicine, 2014 Sulfane sulfurs are one type of important reactive sulfur species. These molecules have unique reactivity that allows them to attach reversibly to other sulfur atoms and exhibit regulatory effects in diverse biological systems. Recent studies have suggested that sulfane sulfurs are involved in signal transduction processes regulated by hydrogen sulfide

New fluorescent probes for sulfane sulfurs and the application in bioimaging [PDF]
Chemical Science, 2013 A sulfane sulfur mediated benzodithiolone formation was developed. Based on this reaction, two fluorescent probes (SSP1 and SSP2) for the detection of sulfane sulfur species (persulfide, polysulfide, and elemental sulfur) were prepared and evaluated. The probes showed high selectivity and sensitivity to sulfane sulfurs.

A Proteomic Approach to Study the Effect of Thiotaurine on Human Neutrophil Activation [PDF]
, 2017 Thiotaurine, a thiosulfonate related to taurine and hypotaurine, is formed by a metabolic process from cystine and generated by a transulfuration reaction between hypotaurine and thiocysteine.
