Pyruvate dehydrogenase kinase 1 (PDK1) is persistently expressed in immune-tolerant monocytes of septic mice and humans and deactivates mitochondrial pyruvate dehydrogenase complex (PDC), the gate-keeping enzyme for glucose oxidation. Pyruvate dehydrogenase is an enzyme that catalyzes the reaction of pyruvate and a lipoamide to give the acetylated dihydrolipoamide and carbon dioxide. The conversion requires the coenzyme thiamine pyrophosphate. Pyruvate dehydrogenase is usually encountered as a component, referred to as E1, of the pyruvate dehydrogenase complex (PDC). •Pyruvate dehydrogenase complex (PDH complex) is a multienzyme complex containing: 3 enzymes + 5 coenzymes + other proteins (+ ATP coenzyme as a regulator) E1 = pyruvate dehydrogenase E2 = dihydrolipoamide acetyltransferase E3 = dihydrolipoamide dehydrogenase Structure of the pyruvate dehydrogenase (PDH) complex In experimental mouse models of acute liver failure, we found that two metabolic enzymes, namely pyruvate dehydrogenase complex and lactic dehydrogenase, translocate to the nucleus resulting in detrimental gene expression. Treatment with an inhibitor of these two enzymes was found to reduce liver damage and to improve survival.

The pyruvate dehydrogenase complex also catalyzes a similar reaction - oxidative decarboxylation of an alpha-keto acid.

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.

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.
