ID   1.8.2.6
DE   S-disulfanyl-L-cysteine oxidoreductase.
AN   sulfur dehydrogenase.
CA   S-disulfanyl-L-cysteinyl-[SoxY protein] + 6 Fe(III)-[cytochrome c] +
CA   3 H2O = S-sulfosulfanyl-L-cysteinyl-[SoxY protein] + 6 Fe(II)-[cytochrome
CA   c] + 7 H(+).
CC   -!- The enzyme is part of the Sox enzyme system, which participates in a
CC       bacterial thiosulfate oxidation pathway that produces sulfate.
CC   -!- The enzyme from the bacterium Paracoccus pantotrophus contains a
CC       molybdoprotein component and a diheme c-type cytochrome component.
CC   -!- The enzyme successively oxidizes the outer sulfur atom in [SoxY
CC       protein]-S-disulfanyl-L-cysteine, using three water molecules and
CC       forming [SoxY protein]-S-sulfosulfanyl-L-cysteine.
CC   -!- During the process, six electrons are transferred to the electron
CC       chain via cytochrome c.
