In enzymology a phosphatidylinositol-3-phosphatase (EC 3.1.3.64) is an enzyme that catalyzes the chemical reaction1-phosphatidyl-1D-myo-inositol 3-phosphate + H2O 1-phosphatidyl-1D-myo-inositol + phosphateThus the two substrates of this enzyme are 1-phosphatidyl-1D-myo-inositol 3-phosphate and H2O whereas its two products are 1-phosphatidyl-1D-myo-inositol and phosphate.This enzyme belongs to the family of hydrolases specifically those acting on phosphoric monoester bonds.
