WebDec 1, 2006 · Phosphatidate phosphatase (PAP) enzymes catalyze the dephosphorylation of phosphatidate, yielding diacylglycerol and inorganic phosphate. In eukaryotic cells, PAP activity has a central role in the synthesis of phospholipids and triacylglycerol through its product diacylglycerol, and it also generates and/or degrades lipid-signaling molecules Webphosphate phosphohydrolase and phosphatidate phosphohydrolase activities in the preparation are attributable to the same enzyme. I-O-Alkyd-rat-glycerol 3- phosphate was hydrolyzed with a V,, of 1.7 nmol min-’ mg-’ of protein and a K, of 270 PM. Phosphatidate phosphohydrolase (EC 3.1.3.4) catalyzes the production
Phosphatidate phosphatase regulates lipid metabolism in several ways. In short, it is a key player in controlling the overall flux of triacylglycerols to phospholipids and vice versa, also exerting control through the generation and degradation of lipid-signaling molecules related to phosphatidate. When the phosphatase is … See more The enzyme phosphatidate phosphatase (PAP, EC 3.1.3.4) is a key regulatory enzyme in lipid metabolism, catalyzing the conversion of phosphatidate to diacylglycerol: a 1,2-diacylglycerol … See more PAP belongs to the family of enzymes known as hydrolases, and more specifically to the hydrolases that act on phosphoric monoester bonds.
