Pyruvate dehydrogenase complex (PDC) deficiency can be inherited in an X-linked manner or in an autosomal recessive manner depending on the gene that has a change (mutation or pathogenic variant). Pyruvate dehydrogenase kinase PDK1 is a metabolic enzyme responsible for switching glucose metabolism from mitochondrial oxidation to aerobic glycolysis in cancer cells, a general hallmark of malignancy termed the Warburg effect. Pyruvate dehydrogenase complex (PDC) is a complex of three enzymes that converts pyruvate into acetyl-CoA by a process called pyruvate decarboxylation. Using recombinant enzymes, it has been shown that phenylbutyrate prevents phosphorylation of E 1alpha through binding and inhibition of pyruvate dehydrogenase kinase, providing a molecular explanation for the beneficial effect of phenylbutyrate on the activity of the pyruvate dehydrogenase complex. Just another WordPress site.  |  Alanine dehydrogenase catalyzes the oxidation and deamination of alanine to produce pyruvate, ammonia and NADH. It can reduce the concentration of ammonia by ammoniation, and indirectly regulate the biosynthesis of antibiotics by regulating ammonia metabolism in cells. It also exists in animals, which main function is to balance the body's metabolism of sugar and amino acid metabolism, especially the body in extreme conditions, the enzyme catalysis to produce large amounts of pyruvate, provide energy for the body. Inhibition of PDK2 suppresses pyruvate carboxylase (PC) flux is decreased, whereas pyruvate dehydrogenase complex (PDC) flux is increased, causing a relative oxaloacetate (OAA) insufficiency. Mitochondrial dysfunction generates a growth-restraining signal linked to pyruvate in. Four groups of mice were studied: lean control, DIO, DIO + DCA, and DIO + PS10. In vivo pyruvate dehydrogenase flux, assessed with hyperpolarized magnetic resonance spectroscopy, was reduced by 59% in hyperthyroid animals (0.0022±0.0002 versus 0.0055±0.0005 second −1; P=0.0003), and this reduction was completely reversed by both short- and long-term delivery of dichloroacetic acid, a pyruvate dehydrogenase … We determined whether metabolic reprogramming, diverting metabolism from aerobic glycolysis back to OXPHOS, would inhibit platelet … Mutational study in the PDHA1 gene of 40 patients suspected of pyruvate dehydrogenase complex deficiency.

However, with the further study on the mechanism of enzymatic protein catalysis, it will be possible to develop appropriate antimicrobial agents and therapeutic drugs targeting pyruvate dehydrogenase in the near future. Dichloroacetate (DCA), a classic PDK inhibitor, has been used to treat diabetic cardiomyopathy, but the lack of specificity and side effects of DCA indicate a more specific inhibitor of PDK is needed. As a result, citrate synthesis is decreased and tricarboxylic acid cycle (TCA) cycle intermediates are diminished. The binding site of pyruvate is located in the groove of two scaffolds in the structural domain. 2014 Feb 14;289(7):4432-43. doi: 10.1074/jbc.M113.533885. 2020 Feb;119(2):545-557. doi: 10.1007/s00436-019-06543-z. pyruvate dehydrogenase complex Inhibitors The Biocompare Inhibitor Search Tool lets researchers browse thousands of compounds by searching by inhibitor name or by its target enzyme.
