Enzyme Information
| 3.13.1.1 |
UDP-sulfoquinovose synthase.
based on mapping to UniProt O48917
UDP-alpha-D-sulfoquinovose + H(2)O = UDP-alpha-D-glucose + sulfite.
-!- 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.
