title: Characterization of cyanide-resistant respiration and appearance of a 36 kDa protein in mitochondria isolated from antimycin A-treated Hansenula anomala.
abstract: Mitochondria exhibiting cyanide-resistant respiration were isolated from Hansenula anomala which had been incubated in the presence of antimycin A to induce cyanide-resistant respiration. The cyanide-resistant respiration in isolated mitochondria was not inhibited by antimycin A or myxothiazol, suggesting that the branching of the pathway from the normal cyanide-sensitive pathway takes place at the coenzyme Q level. Analysis of mitochondrial proteins by sodium dodecyl sulfate gel electrophoresis indicated that a 36 kDa protein was induced by antimycin A treatment of the yeast. It is suggested that this protein is a component of the cyanide-resistant respiratory pathway.
