"At the endoplasmic reticulum (ER) membrane, phosphatidylserine (PS) is hydrolyzed, and has one of its acyl chains cleaved off, by cytosolic phospholipase A2 alpha/beta/delta/epsilon/zeta (PLA2G4A,B,D/E/F) (Ghomashchi et al. 2010), or by group XVI phospholipase A2 (PLA2G16) (Duncan et al. 2008). This produces 1-acyl lysophosphatidylserine (LPS)."^^ . . . . . . . "PS is hydrolyzed to 1-acyl LPS by PLA2[9]"^^ . "3.1.1.4"^^ . . . . .
