ENZYME entry: EC 3.13.1.1

Accepted Name
UDP-sulfoquinovose synthase.
Alternative Name(s)
Sulfite:UDP-glucose sulfotransferase.
Reaction catalysed
UDP-alpha-D-sulfoquinovose + H(2)O <=> UDP-alpha-D-glucose + sulfite
Cofactor(s)
NAD(+).
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.
