1.8.5.6 |
| Accepted name: |
sulfite dehydrogenase (quinone) |
| Reaction: |
sulfite + a quinone + H2O = sulfate + a quinol |
| Other name(s): |
soeABC (gene name) |
| Systematic name: |
sulfite:quinone oxidoreductase |
| Comments: |
This membrane-bound bacterial enzyme catalyses the direct oxidation of sulfite to sulfate in the cytoplasm. The enzyme, characterized from the bacteria Ruegeria pomeroyi and Allochromatium vinosum, is a complex that consists of a membrane anchor (SoeC) and two cytoplasmic subunits: an iron-sulfur protein (SoeB) and a molybdoprotein that contains a [4Fe-4S] iron-sulfur cluster (SoeA). cf. EC 1.8.2.1, sulfite dehydrogenase (cytochrome). |
