Functional Family	Phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta

2.7.1.153

Phosphatidylinositol-4,5-bisphosphate 3-kinase.

based on mapping to UniProt Q8BTI9

ATP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate = ADP + 1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate.

-!- This enzyme also catalyzes the phosphorylation of PtdIns4P to PtdIns(3,4)P(2), and of PtdIns to PtdIns3P.
