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-Rule 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-Rule MF_01162

ATP + an acid + [acyl-carrier-protein] = AMP + diphosphate + acyl-[acyl-carrier-protein]. HAMAP-Rule MF_01162

Subcellular location

Cell inner membrane; Multi-pass membrane protein By similarity HAMAP-Rule 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.
