pyruvate:ubiquinone oxidoreductase
Flavoprotein (FAD) [1]. This bacterial enzyme is located on the inner surface of the cytoplasmic membrane and coupled to the respiratory chain via ubiquinone [2,3]. Does not accept menaquinone. Activity is greatly enhanced by lipids [4,5,6]. Requires thiamine diphosphate [7]. The enzyme can also form acetoin [8].
