This is one of the largest known protein Pyruvate dehydrogenase complex is a multifunctional enzyme complex which catalyzes oxidative decarboxylation of pyruvate to acetyl-CoA, NADH, and CO 2. The overall reaction is carried out by three different enzymes (pyruvate dehydrogenase, dihydrolipoyl transacetylase, and dihydrolipoyl dehydrogenase), which form a tight multienzyme complex that is easily isolated as such by extraction of Pyruvate dehydrogenase complex deficiency (PDCD) is a rare disorder of carbohydrate metabolism caused by a deficiency of one of the three enzymes in the pyruvate dehydrogenase complex (PDC). The age of onset and severity of disease depends on the activity level of the PDC enzymes.

Under aerobic conditions, pyruvate is converted to acetyl CoA which enters the TCA cycle to be oxidized to CO2. ATP is generated. Glycolysis is taking place in cytoplasm. So pyruvate is generated in cytoplasm. This is transported into mitochondria by a pyruvate transporter. The Pyruvate Dehydrogenase complex (PDHc) is responsible for catalyzing the irreversible, rate-limiting step in the aerobic oxidation of pyruvate to acetyl CoA, thereby effectively linking the cytosolic glycolysis metabolic pathway to the mitochondrial citric acid cycle. The PDHc is a large, multisubunit complex located in the mitochondrial matrix. 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.
