A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
UDP-sugar diphosphatase.
Alternative Name(s)
Nucleosidediphosphate-sugar diphosphatase.
Nucleosidediphosphate-sugar pyrophosphatase.
UDP-sugar hydrolase.
UDP-sugar pyrophosphatase.
Reaction catalysed
UDP-sugar + H(2)O <=> UMP + alpha-D-aldose 1-phosphate
Divalent cation.
  • UDP-sugar is the best substrate, although other nucleoside-sugar diphosphates are used as substrates with similar Km values but much lower maximum velocities.
  • Thus, this enzyme has a specificity distinct from that of EC
  • Some but not all enzymes of this class also appear to have EC activity.
