Enzyme Information

2.7.1.153	Phosphatidylinositol-4,5-bisphosphate 3-kinase. based on mapping to UniProt P48736 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.
2.7.11.1	Non-specific serine/threonine protein kinase. based on mapping to UniProt P48736 ATP + a protein = ADP + a phosphoprotein. -!- This is a heterogeneous group of serine/threonine protein kinases that do not have an activating compound and are either non-specific or their specificity has not been analyzed to date. -!- Formerly EC 2.7.1.37 and EC 2.7.1.70.
