Function

function

Plastidial enzyme of the prokaryotic glycerol-3-phosphate pathway that converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at position sn-2 (PubMed:10398728).
Utilizes palmitoyl-ACP (16:0-ACP) to produce phosphatidic acid containing a saturated group at position sn-2, which is characteristic of lipids synthesized by the prokaryotic pathway (PubMed:10398728).
In vitro, can use 16:0-CoA as acyl donor (PubMed:10398728).

Catalytic activity

Pathway

Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 2/3.
