1-acyl-sn-glycerol-3-phosphate acyltransferase gamma (Agpat3)

Converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety in the sn-2 position of the glycerol backbone (PubMed:15367102). Acts on LPA containing saturated or unsaturated fatty acids C16:0-C20:4 in the sn-1 position using C18:1, C20:4 or C18:2-CoA as the acyl donor.

Also acts on lysophosphatidylcholine, lysophosphatidylinositol and lysophosphatidylserine using C18:1 or C20:4-CoA (By similarity). Has a preference for arachidonoyl-CoA as a donor (PubMed:19114731).
