Diacylglycerol pyrophosphate phosphatase
WebThe levels of lipid phosphate phosphatase activities may be used as a marker of signaling events in the cell. In this chapter we describe enzymatic assays that are routinely used to measure the activities of phosphatidate phosphatase, lysophosphatidate phosphatase, and diacylglycerol pyrophosphate phosphatase. WebMar 12, 2009 · Diacylglycerol pyrophosphate phosphatase is a novel enzyme of phospholipid metabolism which is present in S. cerevisiae, Escherichia coli, and mammalian cells.

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. WebDiacylglycerol pyrophosphate (DGPP) phosphatase in the yeast Saccharomyces cerevisiae is a Mg2+-independent and N-ethylmaleimide-insensitive 34-kDa vacuolar …
WebMg2+-dependent phosphatidate (PA) phosphatase (3-sn-phosphatidate phosphohydrolase, EC 3.1.3.4) catalyzes the dephosphorylation of PA to yield diacylglycerol and Pi. In this work, we identified the Saccharomyces cerevisiae PAH1 (previously known as SMP2) gene that encodes Mg2+-dependent PA phosphatase using amino acid sequence information … WebThe DPP1-encoded diacylglycerol pyrophosphate (DGPP) phosphatase enzyme accounts for half of the Mg2+-independent phosphatidate (PA) phosphatase activity in Saccharomyces cerevisiae. The LPP1 (lipid phosphate phosphatase) gene encodes a protein that contains a novel phosphatase sequence motif found in DGPP phosphatase …
WebDiacylglycerol pyrophosphate (DGPP) phosphatase is a novel membrane-associated enzyme that catalyzes the dephosphorylation of the β phosphate of DGPP to yield phosphatidate and Pi. DGPP phosphatase was purified 33,333-fold from Saccharomyces cerevisiae by a procedure that included Triton X-100 solubilization of microsomal … WebOct 9, 1998 · In general, PA is converted to DG by PA phosphatase or to lyso-PA by PLA2 [5]. Therefore, these enzymes may regulate the signaling functions of phosphatidate. Recently, a new mechanism of PA attenuation was reported in which this phospholipid is converted into diacylglycerol pyrophosphate (DGPP) by a phosphatidic acid kinase.
WebJul 18, 2024 · The PA abundance in plants is defined as the balance between enzymes responsible for PA synthesis and degradation. Phosphatidic acid kinase catalyzes PA phosphorylation to yield diacylglycerol pyrophosphate (DGPP). Phosphatidic acid phosphatase (PAP) is another key enzyme to keep a PA’s appropriate balance .
