ENZYME entry: EC 1.8.2.6

Accepted Name
S-disulfanyl-L-cysteine oxidoreductase.
Alternative Name(s)
Sulfur dehydrogenase.
Reaction catalysed
[SoxY protein]-S-disulfanyl-L-cysteine + 6 ferricytochrome c + 3 H(2)O <=> [SoxY protein]-S-sulfosulfanyl-L-cysteine + 6 ferrocytochrome c + 6 H(+)
Comment(s)
  • The enzyme is part of the Sox enzyme system, which participates in a bacterial thiosulfate oxidation pathway that produces sulfate.
  • The enzyme from the bacterium Paracoccus pantotrophus contains a molybdoprotein component and a diheme c-type cytochrome component.
  • The enzyme successively oxidizes the outer sulfur atom in [SoxY protein]-S-disulfanyl-L-cysteine, using three water molecules and forming [SoxY protein]-S-sulfosulfanyl-L-cysteine.
  • During the process, six electrons are transferred to the electron chain via cytochrome c.
