Abstract

An active respiratory chain system was demonstrated in sonically treated mycelium of Streptomyces antibioticus, the producer of antimycin A. The respiratory electron transfer from substrate to oxygen proceeded successively through flavoprotein(s), b-, c-, and a-type cytochromes, and terminated with the cyanide-sensitive cytochrome oxidase. The cytochrome composition of the culture was not affected by the age of the mycelium, the intensity of antimycin A production, or differences in the media. Slater factor, coenzyme Q, and vitamin K were not interposed as hydrogen carriers in the respiratory chain between flavoproteins and cytochromes. The oxidation of reduced nicotinamide adenine dinucleotide and succinate was unaffected by antimycin A. Evidence is presented in support of the absence of the antimycin A-sensitive site from the electron transport system of S. antibioticus.
