Pyruvate dehydrogenase (quinone)

Pyruvate dehydrogenase (quinone) (, pyruvate dehydrogenase, pyruvic dehydrogenase, pyruvic (cytochrome b1) dehydrogenase, pyruvate:ubiquinone-8-oxidoreductase, pyruvate oxidase (ambiguous)) is an enzyme with systematic name pyruvate:ubiquinone oxidoreductase. This enzyme catalyses the following chemical reaction


 * pyruvate + ubiquinone + H2O $$\rightleftharpoons$$ acetate + CO2 + ubiquinol

This bacterial enzyme is located on the inner surface of the cytoplasmic membrane.
