Phosphatidic acid to diacylglycerol
Web2 days ago · In the penultimate step, PA is dephosphorylated by phosphatidic acid phosphatase (PAP) to generate diacylglycerol (DAG). In the acyl-CoA-dependent pathway, the final step is catalyzed by diacylglycerol acyltransferases (DGATs) (i.e., DGAT1 and DGAT 2), which convert DAG and acyl-CoA into TAGs. Websignalling, phosphatidic acid, plant stress signalling, protein kinase. Introduction Phosphatidic acid (PA) has been shown to represent an important lipid second messenger in several eukaryotic systems, including plants. It is produced via the phospho-lipase D (PLD) or the phospholipase C/diacylglycerol kinase-mediated pathways (Meijer and ...

WebFeb 6, 2024 · DAG can emanate from stored fat as triacylglycerol, as well as the glycerophospholipid phosphatidylinositol (PI). In order to produce DAG from triacylglycerol, one of the outer acyl-CoA groups is deacylated by a lipase. Conversely, DAG synthesis from PI requires removal of the inositol group. WebJan 1, 2013 · Phosphatidic acid phosphatase (PAP; EC 3.1.3.4) catalyzes the dephosphorylation of phosphatidic acid (PA) to produce diacylglycerol (DAG) and inorganic phosphate. In seed plants, PA plays pivotal roles both as a precursor to membrane lipids and as a signaling molecule.
