Converts 1-acyl-sn-glycerol-3-phosphate (lysophosphatidic acid or LPA) into 1,2-diacyl-sn-glycerol-3-phosphate (phosphatidic acid or PA) by incorporating an acyl moiety at the sn-2 position of the glycerol backbone (PubMed:21173190). Acts on LPA containing saturated or unsaturated fatty acids C16:0-C20:4 at the sn-1 position using C18:1, C20:4 or C18:2-CoA as the acyl donor (PubMed:21173190). Also acts on lysophosphatidylcholine, lysophosphatidylinositol and lysophosphatidylserine using C18:1 or C20:4-CoA (PubMed:21173190). Has a preference for arachidonoyl-CoA as a donor (By similarity). Has also a modest lysophosphatidylinositol acyltransferase (LPIAT) activity, converts lysophosphatidylinositol (LPI) into phosphatidylinositol (By similarity). a 1-acyl-sn-glycero-3-phosphate + an acyl-CoA = a 1,2-diacyl-sn-glycero-3-phosphate + CoA 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + pentadecanoyl-CoA = 1-(9Z)-octadecenoyl-2-pentadecanoyl-sn-glycero-3-phosphate + CoA 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + heptadecanoyl-CoA = 1-(9Z)-octadecenoyl-2-heptadecanoyl-sn-glycero-3-phosphate + CoA 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + octadecanoyl-CoA = 1-(9Z-octadecenoyl)-2-octadecanoyl-sn-glycero-3-phosphate + CoA 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + nonadecanoyl-CoA = 1-(9Z)-octadecenoyl-2-nonadecanoyl-sn-glycero-3-phosphate + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate = 1-(9Z)-octadecenoyl-2-(5Z,8Z,11Z,14Z)-eicosatetraenoyl-sn-glycero-3-phosphate + CoA (9Z)-octadecenoyl-CoA + 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate = 1,2-di-(9Z-octadecenoyl)-sn-glycero-3-phosphate + CoA (9Z,12Z)-octadecadienoyl-CoA + 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate = 1-(9Z)-octadecenoyl-2-(9Z,12Z)-octadecadienoyl-sn-glycero-3-phosphate + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + 1-(9Z-octadecenoyl)-sn-glycero-3-phosphocholine = 1-(9Z)-octadecenoyl-2-(5Z,8Z,11Z,14Z)-icosatetraenoyl-sn-glycero-3-phosphocholine + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + 1-(9Z-octadecenoyl)-sn-glycero-3-phospho-(1D-myo-inositol) = 1-(9Z-octadecenoyl)-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phospho-1D-myo-inositol + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + 1-(9Z-octadecenoyl)-sn-glycero-3-phospho-L-serine = 1-(9Z-octadecenoyl)-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phospho-L-serine + CoA (9Z)-octadecenoyl-CoA + 1-hexadecanoyl-sn-glycero-3-phosphate = 1-hexadecanoyl-2-(9Z-octadecenoyl)-sn-glycero-3-phosphate + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + 1-hexadecanoyl-sn-glycero-3-phosphate = 1-hexadecanoyl-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + 1-heptadecanoyl-sn-glycero-3-phosphate = 1-heptadecanoyl-2-(5Z,8Z,11Z,14Z)-eicosatetraenoyl-sn-glycero-3-phosphate + CoA (9Z)-octadecenoyl-CoA + 1-octadecanoyl-sn-glycero-3-phosphate = 1-octadecanoyl-2-(9Z-octadecenoyl)-sn-glycero-3-phosphate + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + 1-octadecanoyl-sn-glycero-3-phosphate = 1-octadecanoyl-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate + CoA 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + hexadecanoyl-CoA = 1-hexadecanoyl-2-(9Z-octadecenoyl)-sn-glycero-3-phosphate + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + 1-O-(9Z-octadecenyl)-sn-glycero-3-phosphate = 1-O-(9Z-octadecenyl)-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate + CoA (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + a 1-acyl-sn-glycero-3-phospho-(1D-myo-inositol) = a 1-acyl-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phospho-(1D-myo-inositol) + CoA Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 2/3. Widely expressed with highest levels in testis, pancreas and kidney, followed by spleen, lung, adipose tissue and liver. The HXXXXD motif is essential for acyltransferase activity and may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate. Belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family.
