Each complex consists of three catalytic components: pyruvate dehydrogenase or α -ketoglutarate dehydrogenase (E 1); dihydrolipoyl transacetylase or dihydrolipoyl trans-succinylase (E 2); and dihydrolipoyl dehydrogenase (E 3), a flavopro-tein that is a common component of the two complexes. The pyruvate dehydrogenase complex (PDHc) is a giant enzymatic assembly involved in pyruvate oxidation. PDHc components have been characterized in isolation, but the complex’s quaternary structure has remained elusive due to sheer size, heterogeneity, and plasticity. Nonetheless, the role of the pyruvate dehydrogenase complex (PDC) regulation during the metabolic shift from lactate formation to lactate uptake has not yet been sufficiently investigated. With this study, the interaction of oxidative metabolism with the PDC regulation by phosphorylation–dephosphorylation was descriptively studied for the first time during the lactate shift. The PDHX gene encodes component X of the pyruvate dehydrogenase (PDH) complex.

PDH is a multienzyme complex; The molecular weight of the PDH complex in Escherichia coli is 48,00,000. PDH complex is located in the Matrix Space of Mitochondria of the erythrocytes in the cytoplasm of the prokaryotes. A combination of crystallography, NMR spectroscopy and electron microscopy is revealing the secrets of pyruvate dehydrogenase complex. The complex performs a central step in energy production, catalyzing the reaction that links glycolysis with the tricarboxylic acid cycle. The Pyruvate Dehydrogenase Complex (PDHc) The PDHc is a mitochondrial enzyme complex responsible for the oxidation of pyruvate to acetyl-CoA. The acetyl-CoA can then be fully oxidized to CO 2 and H 2 O in the TCA cycle.

PDHc components have been characterized in isolation, but the complex’s quaternary structure has remained elusive due to sheer size, heterogeneity, and plasticity. Nonetheless, the role of the pyruvate dehydrogenase complex (PDC) regulation during the metabolic shift from lactate formation to lactate uptake has not yet been sufficiently investigated. With this study, the interaction of oxidative metabolism with the PDC regulation by phosphorylation–dephosphorylation was descriptively studied for the first time during the lactate shift. The PDHX gene encodes component X of the pyruvate dehydrogenase (PDH) complex. For a detailed description of the pyruvate dehydrogenase complex, see 300502.The mammalian PDH complex differs from that in E. coli and from the other mammalian alpha-keto acid dehydrogenases by the presence of a 53-kD protein called protein X.
