Publication Abstract from PubMed
Mitochondrial ATP synthase comprises a membrane embedded Fo motor that rotates to drive ATP synthesis in the F1 subunit. We used single-particle cryo-EM to obtain structures of the full complex in a lipid bilayer in the absence or presence of the inhibitor oligomycin, at 3.6 A and 3.8 A resolution, respectively. To limit conformational heterogeneity, we locked the rotor in a single conformation by fusing the F6 subunit of the stator with the delta-subunit of the rotor. Assembly of the enzyme with the F6-delta fusion caused a twisting of the rotor and a 9 degrees rotation of the Fo c10-ring in the direction of ATP synthesis, relative to the structure of isolated Fo Our cryo-EM structures show how F1 and Fo are coupled, give insight into the proton translocation pathway and show how oligomycin blocks ATP synthesis.
