Reaction: 6-sulfo-α-D-quinovose = 6-sulfo-β-D-quinovose
Systematic name: 6-sulfo-D-quinovose 1-epimerase
Comments: The enzyme is found in bacteria that possess sulfoglycolytic pathways. The enzyme can also act on other aldohexoses such as D-galactose, D-glucose, D-glucose-6-phosphate, and D-glucuronate, but with lower efficiency. Does not act on D-mannose.
