With a quinone or similar compound as acceptor
BRITE hierarchy
Sysname
sulfite:quinone oxidoreductase
Reaction(IUBMB)
sulfite + a quinone + H2O = sulfate + a quinol [RN:R11487]
Reaction(KEGG)
Substrate
sulfite [CPD:C00094];
quinone [CPD:C15602];
H2O [CPD:C00001]
Product
sulfate [CPD:C00059];
quinol [CPD:C15603]
Comment
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).
