Mechanism of Active Proton Translocation by Cytochrome Systems

  • Sergio Papa


The cytochrome systems of mitochondria and plasma membrane of prokaryotes catalyze the transfer of reducing equivalents from dehydrogenases to oxygen, or other oxidants, and convert the energy so made available into transmembrane thermodynamic potential difference of protons, \( \Delta {{\tilde{\mu }}_{{{H}^{+}}}} \) (Mitchell, 1966, 1980a; Papa, 1976; Haddock and Jones, 1977; Wikström and Krab, 1979).
