IntEnz Enzyme Nomenclature


Accepted name:
sulfoquinovose mutarotase
Systematic name:
6-sulfo-D-quinovose 1-epimerase



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.
