|eukaryotic sulfide quinone oxidoreductase.
|a quinone + glutathione + H(+) + hydrogen sulfide <=> a quinol + S-sulfanylglutathione|
- 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 220.127.116.11), 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.
