SYSTEMATIC NAME
IUBMB Comments
sulfite:quinone oxidoreductase
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).

expression during thiosulfate oxidation and into early stationary phase
transcription of all SoeABC genes is about 3fold increased during photolithoautotrophic growth on sulfide or thiosulfate compared to photo organoheterotrophic growth on malate
