Dihydroxyacetonephosphate acyltransferase involved in plasmalogen biosynthesis. an acyl-CoA + dihydroxyacetone phosphate = a 1-acylglycerone 3-phosphate + CoA dihydroxyacetone phosphate + hexadecanoyl-CoA = 1-hexadecanoylglycerone 3-phosphate + CoA Membrane lipid metabolism; glycerophospholipid metabolism. May be part of a heterotrimeric complex composed of DAP-AT, ADAP-S and a modified form of DAP-AT. Exclusively localized to the lumenal side of the peroxisomal membrane. Expressed in liver (at protein level). 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 GPAT/DAPAT family.
