In enzymology a phosphatidylinositol-4-phosphate 3-kinase (EC 2.7.1.154) is an enzyme that catalyzes the chemical reactionATP + 1-phosphatidyl-1D-myo-inositol 4-phosphate ADP + 1-phosphatidyl-1D-myo-inositol 34-bisphosphateThus the two substrates of this enzyme are ATP and 1-phosphatidyl-1D-myo-inositol 4-phosphate whereas its two products are ADP and 1-phosphatidyl-1D-myo-inositol 34-bisphosphate.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor.
