Here we report that the four isoenzymes of protein kinase responsible for the phosphorylation and inactivation of pyruvate dehydrogenase (pdk1, pdk2, pdk3 and pdk4) differ in their abilities to phosphorylate the enzyme. Pdk1 can phosphorylate all three sites (s232, s293, s300), whereas pdk2, pdk3 and pdk4 each phosphorylate only s232 and s293. |

PDK1 is a direct HIF-1 target gene. We found that the gene encoding pyruvate dehydrogenase kinase 1 (PDK1) is a direct target of HIF-1. PDK1 phosphorylates the pyruvate dehydrogenase (PDH) E1α subunit and inactivates the PDH enzyme complex that converts pyruvate to acetyl-coenzyme A, thereby inhibiting pyruvate metabolism via the tricarboxylic acid (TCA) cycle |

Activation of glycolytic genes by HIF-1 is considered critical for metabolic adaptation to hypoxia through increased conversion of glucose to pyruvate and subsequently to lactate. We found that HIF-1 also actively suppresses metabolism through the tricarboxylic acid cycle (TCA) by directly trans-activating the gene encoding pyruvate dehydrogenase kinase 1 (PDK1). PDK1 inactivates the TCA cycle enzyme, pyruvate dehydrogenase (PDH), which converts pyruvate to acetyl-CoA. |
