Factors controlling the binding of two protons per electron transferred through the ubiquinone and cytochrome b/c2 segment of Rhodopseudomonas sphaeroides chromatophores.

Abstract

1. On every turnover, 2.0 protons can be bound by the membrane for each single electron moving through the Q-b/c2 oxidoreductase. 2. One proton (H+II) binding reaction is, and one (H+I) is not, sensitive to antimycin. 3. The redox states of electron transfer components other than the proton binding agents can affect both the rate of proton uptake and the apparent pK values on the agents binding the protons. 4. The presence of valinomycin under certain well-defined conditions can strongly influence the value of the measured pK on the H+II binding agent.
