【 摘 要 】

Electron flow from succinate dehydrogenase, or from non-physiological reductants including ascorbate plus phenazine methosulphate, to nitrate reductase in Paracoccus denitrificans is shown to be linked to energy conservation, contrary to previously accepted schemes for electron transport in this organism. The function of the P. denitrificans nitrate reductase is compared with its counterpart in Escherichia coli.
