Reaction(IUBMB)
6-sulfo-alpha-D-quinovose = 6-sulfo-beta-D-quinovose [RN:
R12314 ]
Reaction(KEGG)
Substrate
6-sulfo-alpha-D-quinovose [CPD:
C22077 ]
Product
6-sulfo-beta-D-quinovose [CPD:
C22078 ]
Comment
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.
