Citation | Journal: Science / Year: 2019 Title: Rotary substates of mitochondrial ATP synthase reveal the basis of flexible F-F coupling. Authors: Bonnie J Murphy / Niklas Klusch / Julian Langer / Deryck J Mills / Özkan Yildiz / Werner Kühlbrandt / Abstract: FF-adenosine triphosphate (ATP) synthases make the energy of the proton-motive force available for energy-consuming processes in the cell. We determined the single-particle cryo-electron microscopy ...FF-adenosine triphosphate (ATP) synthases make the energy of the proton-motive force available for energy-consuming processes in the cell. We determined the single-particle cryo-electron microscopy structure of active dimeric ATP synthase from mitochondria of sp. at a resolution of 2.7 to 2.8 angstroms. Separation of 13 well-defined rotary substates by three-dimensional classification provides a detailed picture of the molecular motions that accompany -ring rotation and result in ATP synthesis. Crucially, the F head rotates along with the central stalk and -ring rotor for the first ~30° of each 120° primary rotary step to facilitate flexible coupling of the stoichiometrically mismatched F and F subcomplexes. Flexibility is mediated primarily by the interdomain hinge of the conserved OSCP subunit. A conserved metal ion in the proton access channel may synchronize -ring protonation with rotation. | |||||||||
