At the inner mitochondrial (IR) membrane, phosphatidylglycerol (PG) is hydrolysed, and has one of its acyl chains cleaved off, by phospholipase A2 beta (PLA2G4B) (Ghomashchi et al. 2010) to form 2-acyl lysophosphatidylglycerol (LPG). Phospholipase A2 enzymes show not only PLA2 hydrolysing activity to form the 1-acyl lysophospholipid but also have a degree of PLA1 activity, producing a 2-acyl lysophospholipid.
