ENZYME entry: EC 1.8.2.6

Accepted Name
S-disulfanyl-L-cysteine oxidoreductase
Alternative Name(s)
sulfur dehydrogenase
Reaction catalysed
6 Fe(III)-[cytochrome c] + 3 H2O + S-disulfanyl-L-cysteinyl-[SoxY protein] <=> 6 Fe(II)-[cytochrome c] + 7 H(+) + S-sulfosulfanyl-L-cysteinyl-[SoxY protein]
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.
