Plays a role in lysophospholipid acylation. Transfers fatty acids to the 1-position via an enzyme-bound acyl-ACP intermediate in the presence of ATP and magnesium. Its physiological function is to regenerate phosphatidylethanolamine from 2-acyl-glycero-3-phosphoethanolamine (2-acyl-GPE) formed by transacylation reactions or degradation by phospholipase A1. a 2-acyl-sn-glycero-3-phosphoethanolamine + a fatty acyl-[ACP] = a 1,2-diacyl-sn-glycero-3-phosphoethanolamine + holo-[ACP] a long-chain fatty acid + ATP + holo-[ACP] = a long-chain fatty acyl-[ACP] + AMP + diphosphate In the N-terminal section; belongs to the 2-acyl-GPE acetyltransferase family. In the C-terminal section; belongs to the ATP-dependent AMP-binding enzyme family.
