In enzymology, an ADP-sugar diphosphatase ({{EC number|3.6.1.21}}) is an enzyme that catalyzes the chemical reaction

ADP-sugar + H₂O AMP + alpha-D-aldose 1-phosphate

Thus, the two substrates of this enzyme are ADP-sugar and H₂O, whereas its two products are AMP 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 ADP-sugar sugarphosphohydrolase. Other names in common use include ADP-sugar pyrophosphatase, and adenosine diphosphosugar pyrophosphatase. This enzyme participates in 3 metabolic pathways: fructose and mannose metabolism, purine metabolism, and starch and sucrose metabolism.
