General description

Phosphatidylinositol-specific phospholipase C (PI-PLC) from Bacillus cereus is a 298 residual protein. It belongs to the class of ubiquitous enzymes. PI-PLC is characterized with a single globular domain and it folds into eight (βα) barrel sheets, out of which only six βα units are found in barrel, lacking helices between strands IV and V and V and VI.


Phospholipase C, Phosphatidylinositol-specific from Bacillus cereus has been used to cleave GPI-anchored protein from green fluorescent protein- glycosylphosphatidylinositol (GFP-GPI) from the cell membrane. It has also been used in invasion assay to test the involvement of PLAP in T. cruzi invasion to human epithelial type 2 (HEp-2) cells.

Biochem/physiol Actions

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

Contains phosphate buffer salts, EDTA and stabilizer

Analysis Note

Acetylcholinesterase is measured according to Ellman, et al.

Iron and other transition metals, such as copper and manganese, are essential for supporting brain function, yet over-accumulation is cytotoxic. This over-accumulation of metals, particularly iron, is common to several neurological disorders; these include Alzheimer's disease, Parkinson's disease, Friedrich's ataxia
