Reaction: 6-sulfo-D-quinovose + O2 + 2-oxoglutarate = 6-dehydro-D-glucose + hydrogensulfite + succinate + CO2
Glossary: 6-sulfo-D-quinovose = sulfoquinovose = 6-deoxy-6-sulfo-D-glucopyranose
Other name(s): SQ dioxygenase; sqoD (gene name)
Systematic name: 6-sulfo-D-quinovose,2-oxoglutarate:oxygen oxidoreductase (sulfite-forming)
Comments: The enzyme, characterized from the marine bacterium Marinobacterium aestuarii, participates in a sulfolytic degradative pathway of sulfoquinovose by cleaving the carbon-sulfur bond. The enzyme requires Fe(II). cf. EC 1.1.1.390 (sulfoquinovose 1-dehydrogenase) and EC 1.14.14.181 (sulfoquinovose monooxygenase).
