Enzyme Information
| 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.
