"At the endoplasmic reticulum (ER) membrane, phosphatidylinositol (PI) is hydrolyzed, and has one of its acyl chains cleaved off, by cytosolic phospholipase A2 delta/epsilon (PLA2G4D/E) Ghomashchi et al. 2010). This produces 2-acyl lysophosphatidylinositol (LPI). Cytosolic phospholipase A2 enzymes show not only PLA2 hydrolyzing activity to form the 1-acyl lysophospholipid but also have a degree of PLA1 activity, producing a 2-acyl lysophospholipid."^^ . . . . . . "PI is hydrolyzed to 2-acyl LPI by PLA2[13]"^^ . "3.1.1.32"^^ . . . . . . . .
