Polyclonal Rabbit Affinity Purified B IH
Pyruvate dehydrogenase kinase 1 (PDK1), a 48kD member of
the mitochondrial matrix protein kinase family, is related to the
histidine protein kinases found in prokaryotes. A mitochondrial multiple subunit enzyme, pyruvate dehydrogenase (PDH) catalyses the oxidative decarboxylation of pyruvic acid to generate acetyl-CoA, NADH, and CO2. This reaction is central to the homeostasis of carbohydrate fuels in mammals. Along with three other isoforms, PDK1 is responsible for phosphorylation and concomitant inactivation of PDH, the E1 component of the multi-enzyme pyruvate dehydrogenase complex. Phosphorylation of PDH by PDK1 occurs at three serine residues on the E1 alpha subunits: Ser264, Ser271, and Ser203. In vitro studies indicate that PDK1 is the only isoenzyme able to phosphorylate Ser203 of PDH, while PDK2 and PDK3 exhibit the strongest activity toward Ser264 and Ser271, respectively. Northern blot analysis reveals that PDK1 is predominantly expressed in heart tissue.
