Comment typeDescription
Biophysicochemical PropertiesKinetic parameters: KM=0.74 mM for ATP {ECO:0000269|PubMed:16081412}; Vmax=0.34 pmol/min/ug enzyme toward 1,2-dioleoyl-sn-glycerol {ECO:0000269|PubMed:16081412}; pH dependence: Optimum pH is 6.8. {ECO:0000269|PubMed:16081412};
Catalytic ActivityATP + 1,2-diacyl-sn-glycerol = ADP + 1,2- diacyl-sn-glycerol 3-phosphate. {ECO:0000269|PubMed:16081412}.
FunctionPhosphorylates the second messenger diacylglycerol (DAG) to generate phosphatidic acid (PA), another important signaling molecule. PA is required for plant development and responses to abiotic stress and pathogen attack. May be involved in the accumulation of PA during cold stress xhibits high specificity for 1,2-dioleoyl-sn-glycerol (1,2-DOG), 1-palmitoyl, 2-oleoyl-sn- glycerol (1,2 POG), 1-stearoyl, 2-linoleoyl-sn-glycerol (1,2-SLG) and 1-oleoyl, 2-palmitoyl-sn-glycerol (1,2-OPG). {ECO:0000269|PubMed:16081412, ECO:0000269|PubMed:23346092}.
