EC 1.8.2.5     
Accepted name: thiosulfate reductase (cytochrome)
Reaction: sulfite + hydrogen sulfide + 2 ferricytochrome c3 = thiosulfate + 2 ferrocytochrome c3
Systematic name: sulfite,hydrogen sulfide:ferricytochrome-c3 oxidoreductase (thiosulfate-forming)
Comments: The enzyme is found in sulfate-reducing bacteria. The source of the electrons is molecular hydrogen, via EC 1.12.2.1, cytochrome-c3 hydrogenase. The organisms utilize the sulfite that is produced for energy generation by EC 1.8.99.5, dissimilatory sulfite reductase.
