ASPG PrEST Antigen

Protein function: Exhibits lysophospholipase, transacylase, PAF acetylhydrolase and asparaginase activities. 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). 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. [The UniProt Consortium] Buffer: PBS and 1M Urea, pH 7.4.
