Reduction of Coenzyme Q by Succinic Acid Dehydrogenase


Crane, Hatefi, Lester and Widmer1,2 have shown that coenzyme Q is reduced by mitochondria or derivative particles like electron-transporting particles, or succinic dehydrogenase complex, and that this reaction is sensitive to antimycin A. We have now succeeded in reducing coenzyme Q with a soluble preparation of succinic acid dehydrogenase, and this reaction was not sensitive to antimycin A.
