1985-11-05 · A hybrid complex containing pyruvate dehydrogenase subunits from pyruvate dehydrogenase complex. Steginsky CA, Gruys KJ, Frey PA. The alpha-ketoglutarate dehydrogenase complex of Escherichia coli utilizes pyruvate as a poor substrate, with an activity of 0.082 units/mg of protein compared with 22 units/mg of protein for alpha-ketoglutarate.

Pyruvate dehydrogenase complex

This multienzyme complex catalyses the conversion of pyruvate and coenzyme A (CoA) to acetyl CoA. The mitochondrial pyruvate dehydrogenase (PDH) complex catalyzes the oxidative decarboxylation of pyruvate, linking glycolysis to the tricarboxylic acid cycle  This complex catalyzes the oxidative decarboxylation of pyruvate to yield acetyl- CoA to feed carbohydrate carbon into the TCA cycle and to capture reducing  Oct 23, 2018 Oxidative metabolism entails the further catabolism of pyruvate.

Pyruvate dehydrogenase complex

By exclusion chromatography on Sephadex G-100 a molecular weight of 21 000 was estimated. The pyruvate dehydrogenase complex (PDC)/pyruvate dehydrogenase kinase (PDK) axis directs the universal survival principles of immune resistance and tolerance in monocytes by controlling anabolic and catabolic energetics. pyruvate dehydrogenase complex, 2-(alpha-hydroxyethyl)-TPP linked [mitochondrial matrix] De activiteit van het PDH-complex wordt geregeld door de staat van fosforylering en is het meest actief in de gedefosforyliseerde staat. 1985-11-05 · A hybrid complex containing pyruvate dehydrogenase subunits from pyruvate dehydrogenase complex. Steginsky CA, Gruys KJ, Frey PA. The alpha-ketoglutarate dehydrogenase complex of Escherichia coli utilizes pyruvate as a poor substrate, with an activity of 0.082 units/mg of protein compared with 22 units/mg of protein for alpha-ketoglutarate. Pyruvate dehydrogenase may be allosterically activated by fructose-1,6-bisphosphate and is inhibited by NADH and acetyl-CoA.

The alpha-ketoglutarate dehydrogenase complex of Escherichia coli utilizes pyruvate as a poor substrate, with an activity of 0.082 units/mg of protein compared with 22 units/mg of protein for alpha-ketoglutarate. Pyruvate dehydrogenase may be allosterically activated by fructose-1,6-bisphosphate and is inhibited by NADH and acetyl-CoA. Phosphorylation of PDH is mediated by a special regulatory enzyme, pyruvate dehydrogenase kinase.
