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 + H(2)O <=> UMP + alpha-D-aldose 1-phosphate
Cofactor(s)
Divalent cation.
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.
