WebOct 29, 2009 · DGPP , previously named pyrophosphatidic acid, is a glycerophospholipid consisting of a pyrophosphate group attached to diacylglycerol (DAG) (Fig. 1).It was first identified by mass spectrometry and 31 P-NMR analysis as an in vitro product of a lipid kinase activity in the microsomal fraction of suspension-cultured Catharanthus roseus … WebApr 1, 2012 · PA can be converted to DAG by lipid phosphate phosphatase (LPP), phosphatidic acid phosphatase (PAP) and PA hydrolase (PAH), and specifically in plants to DAG pyrophosphate (DGPP) by PA kinase (PAK). DGPP can be converted to PA by LPPs such as diacylglycerol pyrophosphate phosphatase. The pathway involving these …

Roles of phosphatidate phosphatase enzymes in lipid metabolism

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 … WebDiacylglycerol pyrophosphate (DGPP) phosphatase in the yeast Saccharomyces cerevisiae is a Mg2+-independent and N-ethylmaleimide-insensitive 34-kDa vacuolar … learning to read first words

WebDiacylglycerol pyrophosphate phosphatase is a novel enzyme of phospholipid metabolism which is present in S. cere˝isiae, Escherichia coli, and mammalian cells. This … WebPA by LPPs such as diacylglycerol pyrophosphate phosphatase. The pathway involving these molecules is shown in Figure1. Certain phospholipids, in particular PA and IP3, play impor-tant modulating roles in plants. PA is a key lipid signaling molecule, and its involvement in the stress response, in Webacid (PA), diacylglycerol (DAG), lysophospholipids, or free fatty acids, may be attributed to the action of multiple phospholipases (Lee et al. 1997, Ryu and Wang 1998, van der Luit et al. 2000, Wang 2000). These find-ings raise the possibility that crosstalk may occur among various phospholipases in mediating cellular functions. learning to read electrical schematics
