Abstract:
Two -type cytochrome components, differing in their mid-point redox potentials as well as their reactivities toward CO, are demonstrated in the membrane particle of by potentiometric titration. The low redox component is revealed to be CO-reactive while the higher redox component is not. Accordingly, the later cytochrome is believed not to be directly involved in the reduction of oxygen while the former component is the cytochrome of .
