General description

Phospholipase C (PI-PLC) from Bacillus cereus has irregular triosephosphate isomerase (TIM)-barrel structure with eight-standard parallel β barrel. It is a 28 kDa protein.

Application

Phospholipase C, Phosphatidylinositol-specific from Bacillus cereus has been used:
  • in the hydrolysis of substrates p-nitrophenylphosphorylcholine (p-NPPC) and p-nitrophenylphosphorylphosphate (p-NPP)
  • to cleave glycosylphosphatidylinositol (GPI) anchor of lynx1 protein and its detachment from plasma membrane
  • to cleave immunolabeled HeLa cells

Biochem/physiol Actions

Phospholipase C (PI-PLC) releases diacylglycerol by cleaving the glycosylphosphatidylinositol. It has broad substrate specificity and its activity is influenced by metal ions and surfactants.
Used for the release of GPI anchored proteins from the membrane.

Unit Definition

One unit will liberate one unit of acetylcholinesterase per minute from a membrane-bound crude preparation at pH 7.4 at 30 °C (10 minute incubation).

Physical form

Solution in 60% (v/v) glycerol containing 10 mM Tris-HCl, pH 8.0 and 10 mM EDTA

Analysis Note

Acetylcholinesterase is measured according to Ellman, et al.

In the authors' previous studies, they found that phosphatidylcholine-specific phospholipase C (PC-PLC) and phosphatidylinositol-specific phospholipase C (PI-PLC) played contrary roles in the apoptosis of vascular endothelial cells (VECs), but the mechanism underlying the phenomenon remains unclear.
