Accepted name: sulfoquinovose monooxygenase
Reaction: 6-sulfo-D-quinovose + FMNH2 + O2 = 6-dehydro-D-glucose + FMN + sulfite + H2O
Glossary: D-quinovose = 6-deoxy-D-glucopyranose
6-dehydro-D-glucose = 6-oxo-D-quinovose
Other name(s): 6-deoxy-6-sulfo-D-glucose monooxygenase; smoC (gene name); squD (gene name)
Systematic name: 6-sulfo-D-quinovose,FMNH2:oxygen oxidoreductase
Comments: The enzyme, characterized from the bacteria Agrobacterium fabrum and Rhizobium oryzae, is involved in a D-sulfoquinovose degradation pathway. FMNH2 is provided by an associated FMN reductase [SmoA, EC, FMN reductase (NADH)].
