In enzymology a phosphatidylinositol-34-bisphosphate 4-phosphatase (EC 3.1.3.66) is an enzyme that catalyzes the chemical reaction1-phosphatidyl-myo-inositol 34-bisphosphate + H2O 1-phosphatidyl-1D-myo-inositol 3-phosphate + phosphateThus the two substrates of this enzyme are 1-phosphatidyl-myo-inositol 34-bisphosphate and H2O whereas its two products are 1-phosphatidyl-1D-myo-inositol 3-phosphate and phosphate.This enzyme belongs to the family of hydrolases specifically those acting on phosphoric monoester bonds.
