abstract：:Complex I (NDH-1) translocates protons across the membrane using electron transfer energy. Two different coupling mechanisms are currently being discussed for complex I: direct (redox-driven) and indirect (conformation-driven). Semiquinone (SQ) intermediates are suggested to be key for the coupling mechanism. Recently...
