Enzyme Information
| 2.7.1.153 |
Phosphatidylinositol-4,5-bisphosphate 3-kinase.
based on mapping to UniProt P42336
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 P42336
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.
