Enzyme Information
| 1.2.5.1 |
Pyruvate dehydrogenase (quinone).
based on mapping to UniProt P07003
Pyruvate + ubiquinone + H(2)O = acetate + CO(2) + ubiquinol.
-!- This bacterial enzyme is located on the inner surface of the cytoplasmic membrane and coupled to the respiratory chain via ubiquinone. -!- Does not accept menaquinone. -!- Activity is greatly enhanced by lipids. -!- Requires thiamine diphosphate. -!- The enzyme can also form acetoin.
