ENZYME entry: EC 3.13.1.1

PURL: https://purl.expasy.org/enzyme/EC/3.13.1.1
Accepted Name
UDP-sulfoquinovose synthase
Alternative Name(s)
sulfite:UDP-glucose sulfotransferase
Reaction catalysed
sulfite + UDP-alpha-D-glucose + H(+) = UDP-alpha-D-6-sulfoquinovose + H2O
Comment(s)
  • NAD(+) appears to oxidize the substrate to UDP-4-dehydroglucose, which dehydrates to UDP-4-dehydro-6-deoxygluc-5-enose, to which sulfite can add; the reaction is completed when the substrate is rehydrogenated at C-4.
  • The enzyme from Arabidopsis thaliana is specific for UDP-Glc and sulfite.
