Abstract: The preparation from beef heart mitochondria and the properties, of a highly active and stable enzyme system, capable of catalyzing the reduction of cytochrome c by reduced coenzyme Q2 are described. The enzyme complex contains cytochrome b and cytochrome c1 in high concentration, and is free of cytochrome c oxidase, cytochrome c, flavoproteins, and the citric acid cycle dehydrogenases. The activity of the enzyme corresponds to a QO2, of about 320,000 at 38°. This activity is strongly inhibited by antimycin A, 2-nonyl-4-hydroxy-quinoline-N-oxide, and 2-alkyl-3-hydroxynaphthoquinone. Amytal, thenoyltrifluoroacetone, and a number of specific metal-chelating compounds are ineffective as inhibitors. • Keywords: Q-junction, Coenzyme Q, Reduced coenzyme Q (QH2), Cytochrome c reductase, Beef heart
