ENZYME entry: EC 3.1.4.11

Accepted Name
Phosphoinositide phospholipase C.
Alternative Name(s)
1-phosphatidyl-D-myo-inositol-4,5-bisphosphate inositoltrisphosphohydrolase.
1-phosphatidylinositol-4,5-bisphosphate phosphodiesterase.
Monophosphatidylinositol phosphodiesterase.
Phosphatidylinositol phospholipase C.
Phosphoinositidase C.
PI-PLC.
Triphosphoinositide phosphodiesterase.
Reaction catalysed
1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H(2)O <=> 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol
Comment(s)
  • 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.
