ENZYME entry: EC 3.6.1.45

Accepted Name
UDP-sugar diphosphatase
Alternative Name(s)
nucleosidediphosphate-sugar diphosphatase
nucleosidediphosphate-sugar pyrophosphatase
UDP-sugar hydrolase
UDP-sugar pyrophosphatase
Reaction catalysed
UDP-sugar + H2O <=> UMP + alpha-D-aldose 1-phosphate
Comment(s)
  • 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 3.6.1.21.
  • Some but not all enzymes of this class also appear to have EC 3.1.3.5 activity.
