Comment typeDescription
Catalytic ActivityAcyl-CoA + sn-glycerol 3-phosphate = CoA + 1- acyl-sn-glycerol 3-phosphate.
DomainThe HXXXXD motif is essential for acyltransferase activity and may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate. {ECO:0000250}.
FunctionEsterifies acyl-group from acyl-ACP to the sn-1 position of glycerol-3-phosphate. The enzyme from chilling-resistant plants discriminates against non-fluid palmitic acid and selects oleic acid whereas the enzyme from sensitive plants accepts both fatty acids. This is an oleate-selective acyltransferase.
PathwayPhospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 1/3.
SimilarityBelongs to the GPAT/DAPAT family. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast stroma.
