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. |
