In enzymology, an UDP-sugar diphosphatase (EC 3.6.1.45) is an enzyme that catalyzes the chemical reaction

UDP-sugar + H2O UMP + alpha-D-aldose 1-phosphate

Thus, the two substrates of this enzyme are UDP-sugar and H2O, whereas its two products are UMP and alpha-D-aldose 1-phosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides in phosphorus-containing anhydrides. The systematic name of this enzyme class is UDP-sugar sugarphosphohydrolase. Other names in common use include nucleosidediphosphate-sugar pyrophosphatase, nucleosidediphosphate-sugar diphosphatase, UDP-sugar hydrolase, and UDP-sugar pyrophosphatase.

Structural studies

As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1HO5, 1HP1, 1HPU, 1OI8, 1OID, and 1OIE.

ADP-ribose diphosphatase (EC 3.6.1.13) is an enzyme that catalyzes a hydrolysis reaction in which water nucleophilically attacks ADP-ribose to produce AMP and D-ribose 5-phosphate. Enzyme hydrolysis occurs by the breakage of a phosphoanhydride bond and is dependent on Mg2+ ions that are held in complex by the enzyme.
