Reaction: PG is hydrolyzed to 2-acyl LPG by PLA2[14]
- in pathway: Acyl chain remodelling of PG
At the endoplasmic reticulum (ER) membrane, phosphatidylglycerol (PG) is hydrolyzed, and has one of its acyl chains cleaved off, by cytosolic phospholipase A2 delta/zeta (PLA2G4D/F) (Ghomashchi et al. 2010) to form 2-acyl lysophosphatidylglycerol (LPG). 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.
