Phosphatidate phosphohydrolase
WebJul 31, 1985 · In lung microsomes, labeled phosphatidic acid and diacylglycerols were synthesized from the endogenous free fatty acids and sn-[14C]glycerol 3-phosphate, which had previously been added. By addition of CDPcholine to the prelabeled microsomes the synthesis of phosphatidylcholine was measured.

Both forms of … WebSubsequent DAG production was inhibited by the phosphatidate phosphohydrolase (PAP) inhibitor, propranolol. R59949, a DAG kinase inhibitor, increased DAG accumulation and blocked the second PA wave. These results suggest that docetaxel triggers a metabolic cascade consisting in PLD-mediated PC hydrolysis, PA release, PAP-dependent DAG ...
WebMay 11, 2010 · Phosphatidic acid is converted to diacylglycerol by phosphatidate phosphohydrolase-1 before final addition of another fatty acyl-CoA to yield TAG. This final stage in the pathway is performed by diacylglycerol acyltransferase (DGAT). Two DGAT enzymes, DGAT1 and DGAT2, have been identified, which appear to have distinct … WebJan 1, 2012 · Phosphatidic acid phosphohydrolase (3-sn-phosphatidate phosphohydrolase, EC 3.1.3.4), also known as PAP, catalyzes the dephosphorylation of phosphatidic acid (PtdOH) to form diacylglycerol (DAG ...
WebTwo isoforms of phosphatidate phosphohydrolase are found in mammalian cells; the one involved in glycerolipid biosynthesis appears to be both cytosolic and in the endoplasmic reticulum. The other isoform is plasma membrane-associated and functions primarily in signal transduction. WebPhosphatidate phosphatase (3-sn-phosphatidate phosphohydrolase) catalyzes the conversion of phosphatidate to diacylglycerol. In the yeast, Saccharomyces cerevisiae (S. cerevisiae), phosphatidate phosphatase is associated with the membrane and cytosolic fractions of the cell.
