The enzyme in conjunction with Pah1 PA phosphatase controls the levels of PA and DAG for the. WebDiacylglycerol kinases (DGKs) are a family of enzymes that catalyze the ATP-dependent phosphorylation of diacylglycerol (DAG) to phosphatidic acid (PtdOH). Despite the critical role in lipid biosynthesis, both DAG and PtdOH have been shown as bioactive lipids mediating a number of signaling pathways.

The role of PA in the cell can be divided into three categories: • PA is the precursor for the biosynthesis of many other lipids. • The physical properties of PA influence membrane curvature. • PA acts as a signaling lipid, recruiting cytosolic proteins to appropriate membranes (e.g., sphingosine kinase 1 ). WebPhosphatidic acid, a key intermediate in lipid metabolism Phosphatidic acid (PtdOH) is an essential substrate for enzymes involved in the synthesis of glycerophospholipids and triacyl-glycerols. PtdOH enters the biosynthetic pathway of phos-pholipids through a CTP-dependent activation catalyzed by CDP-diacylglycerol synthase. solar operations
