What is "sugar-phosphatase"

In enzymology, a sugar-phosphatase is an enzyme that catalyzes the chemical reaction

sugar phosphate + HO $\rightleftharpoons$ sugar + phosphate

Thus, the two substrates of this enzyme are sugar phosphate and HO, whereas its two products are sugar and phosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is sugar-phosphate phosphohydrolase.
