Purification of a rotenone-insensitive NAD(P)H dehydrogenase from the inner surface of the inner membrane of red beetroot mitochondria

Summary, in English

The soluble fraction of disrupted red beetroot mitochondria was resolved by anion-exchange chromatography. Three NADH-oxidising activities were found, including one duroquinone reductase oxidising both NADH and NADPH. This NAD(P)H-duroquinone reductase, which we assign as the internal rotenone-insensitive NAD(P)H dehydrogenase, was further purified by affinity chromatography into a 26 kDa polypeptide.
