|Eukaryotic sulfide quinone oxidoreductase.
|Hydrogen sulfide + glutathione + a quinone <=> S-sulfanylglutathione + a quinol|
- This eukaryotic enzyme, located at the inner mitochondrial membrane,
catalyzes the first step in the metabolism of sulfide.
- While both sulfite and glutathione have been shown to act as sulfane
sulfur acceptors in vitro, it is thought that the latter acts as the
main acceptor in vivo.
- The electrons are transferred via FAD and quinones to the electron
- Unlike the bacterial homolog (EC 184.108.40.206), which repeats the
catalytic cycle without releasing the product, producing a
polysulfide, the eukaryotic enzyme transfers the persulfide to an
acceptor at the end of each catalytic cycle.
