physiological function | in the absence of the tightly bound quinone, a strongly diminished rate of electrocatalytic reduction of oxygen is detected, which can be restored by adding quinones. The stabilization of the radical is not necessary for the oxygen reaction. The reaction mechanism should involve a one electron transfer step from the quinone radical to the next electron acceptor, the heme b | Escherichia coli |
