Protein existence	Inferred from homology

General annotation (Comments)

Function	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 By similarity. HAMAP MF_01162
Catalytic activity	Acyl-[acyl-carrier-protein] + O-(2-acyl-sn-glycero-3-phospho)ethanolamine = [acyl-carrier-protein] + O-(1-beta-acyl-2-acyl-sn-glycero-3-phospho)ethanolamine. HAMAP MF_01162 ATP + an acid + [acyl-carrier-protein] = AMP + diphosphate + acyl-[acyl-carrier-protein]. HAMAP MF_01162
Subcellular location	Cell inner membrane; Multi-pass membrane protein By similarity HAMAP MF_01162.
Sequence similarities	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.
