Comments
Comment typeDescription
Biophysicochemical PropertiesKinetic parameters: Vmax=86.85 pmol/min/mg enzyme {ECO:0000269|PubMed:12897259};
Catalytic ActivityAcyl-CoA + sn-glycerol 3-phosphate = CoA + 1- acyl-sn-glycerol 3-phosphate. {ECO:0000269|PubMed:12897259}.
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, an essential step in glycerolipid biosynthesis.
PathwayPhospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 1/3.
SimilarityBelongs to the GPAT/DAPAT family. {ECO:0000305}.
Subcellular LocationMembrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
Tissue SpecificityWeakly or not expressed in roots, leaves, seedlings, developing siliques and flower buds. {ECO:0000269|PubMed:12897259}.
