【 摘 要 】

Micromolar concentrations of the uncoupler 3-chlorophenylhydrazonepropanedinitrile caused the release of nitric oxide from the cells of Paracoccus denitrificans respiring nitrite. At the same time, a new component with an absorption maximum at 573 nm could be observed in the difference spectra. Damped oscillations of the concentrations of the cytochrome c-NO complex were observed during the trapping of released NO by added mammalian cytochrome c; reduced cytochrome c accumulated simultaneously in the reaction mixture.
