FunFam 20: Udp-sulfoquinovose synthase, chloroplastic

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
UDP-sulfoquinovose synthase. [EC: 3.13.1.1]
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.
