| Enzyme Function | FUNCTION: Exhibits lysophospholipase, transacylase, PAF acetylhydrolase and asparaginase activities (PubMed:9575212, PubMed:8119970, PubMed:10320809). Can catalyze three types of transacylation reactions: (1) acyl transfer from 1-acyl-sn-glycero-3-phosphocholine (1-acyl-GPC) to the sn-1(3) positions of glycerol and 2-acylglycerol (sn-1 to -1(3) transfer), (2) acyl transfer from 1-acyl-GPC to the sn-2 positions of 1-acyl-GPC, 1-acyl-sn-glycero-3-phosphoethanolamine (1-acyl-GPE), and other lysophospholipids (sn-1 to -2 transfer) and (3) acyl transfer from 2-acyl-GPC to the sn-1 position of 2-acyl-GPC and 2-acyl-GPE (sn-2 to -1 transfer) (PubMed:10320809). Mediates the synthesis of 1-arachidonoyl species of phospholipids by transferring the arachidonoyl residue from 2-arachidonoyl lysophospholipid to the sn-1 position of 2-acyl lysophospholipid (PubMed:10320809). {ECO:0000269|PubMed:10320809, ECO:0000269|PubMed:8119970, ECO:0000269|PubMed:9575212}. |
