WebAbstract. We tested how the addition of oxaloacetate (OAA) to SH-SY5Y cells affected bioenergetic fluxes and infrastructure, and compared the effects of OAA to malate, pyruvate, and glucose deprivation. OAA displayed pro-glycolysis and pro-respiration effects. OAA pro-glycolysis effects were not a consequence of decarboxylation to …

During gluconeogenesis, pyruvate carboxylase is involved in the synthesis of phosphoenolpyruvate (PEP) from pyruvate. Pyruvate is first converted by pyruvate carboxylase to oxaloacetate (OAA) in the mitochondrion requiring hydrolysis of one molecule of ATP. The OAA is then decarboxylated and … See more Pyruvate carboxylase (PC) encoded by the gene PC is an enzyme (EC 6.4.1.1) of the ligase class that catalyzes (depending on the species) the physiologically irreversible carboxylation of pyruvate to form oxaloacetate See more Structural studies of PC have been conducted by electron microscopy, by limited proteolysis, and by cloning and gasa sequencing of genes and cDNA encoding the enzyme. Most well characterized forms of active PC consist of four identical … See more As a crossroad between carbohydrate and lipid metabolism, pyruvate carboxylase expression in gluconeogenic tissues, adipose tissues … See more The reaction mechanism can be subdivided into two partial reactions (see figure to the right). In the first reaction, ATP is carboxylated to produce carbonic phosphoric … See more • Pyruvate carboxylase deficiency See more • GeneReviews/NCBI/NIH/UW entry on Pyruvate Carboxylase Deficiency See more Webpyruvate is created in the mitochondrial intermembrane space, and then for pyruvate to enter the mitochondrial matrix, it has to be converted to OAA (through malate shuttle) I was under the impression that the malate shuttle is to transport the NADH made during glycolysis into the mitochondria. corner house landscape ideas
