The enzyme phosphatidylinositol-3-phosphatase (EC 3.1.3.64) catalyzes the reaction
1-phosphatidyl-1D-myo-inositol 3-phosphate + H2O
\rightleftharpoons
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name is 1-phosphatidyl-1D-myo-inositol-3-phosphate 3-phosphohydrolase. Other names in common use include inositol-1,3-bisphosphate 3-phosphatase, inositol 1,3-bisphosphate phosphatase, inositol-polyphosphate 3-phosphatase, D-myo-inositol-1,3-bisphosphate 3-phosphohydrolase, and phosphatidyl-3-phosphate 3-phosphohydrolase. This enzyme participates in inositol phosphate metabolism and phosphatidylinositol signaling system.
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and .
