Enzyme Information
| 3.1.4.11 |
Phosphoinositide phospholipase C.
based on mapping to UniProt Q01970
1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H(2)O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol.
-!- These enzymes form some of the cyclic phosphate Ins(cyclic 1,2)P(4,5)P(2) as well as Ins(1,4,5)P(3). -!- They show activity toward phosphatidylinositol, i.e., the activity of EC 4.6.1.13 in vitro at high calcium concentration.
