The switching of electron flux from the cyanide-insensitive oxidase to the cytochrome pathway in mung-bean (Phaseolus aureus L.) mitochondria.
The activities of the mung-bean (Phaseolus aureus L.) mitochondrial cyanide-insensitive oxidase and cytochrome pathways have been measured simultaneously. The results show that electrons can be diverted both from the alternative pathway to the cytochrome pathway and from the cytochrome to the alternative pathway. The competition of the two pathways for the available electron flux is discussed.
