The oxidation-reduction potentials of four periplasmic electron carrier proteins from Paracoccus denitrificans have been determined. Their midpoint potentials are: amicyanin, 294 +/- 6 mV; cytochrome c-550, 253 +/- 5 mV; cytochrome c-551i, 190 +/- 4 mV; and cytochrome c-553i, 148 +/- 5 mV. Although rapid amicyanin-mediated transfer of electrons from methylamine dehydrogenase to cytochrome c-551i was observed, reduced amicyanin did not reduce oxidized cytochrome c-551i in the absence of methylamine dehydrogenase.
