Citation | Journal: Nat Commun / Year: 2020Title: Cryo-EM structures provide insight into how E. coli FF ATP synthase accommodates symmetry mismatch. Authors: Meghna Sobti / James L Walshe / Di Wu / Robert Ishmukhametov / Yi C Zeng / Carol V Robinson / Richard M Berry / Alastair G Stewart / ![]() Abstract: FF ATP synthase functions as a biological rotary generator that makes a major contribution to cellular energy production. It comprises two molecular motors coupled together by a central and a ...FF ATP synthase functions as a biological rotary generator that makes a major contribution to cellular energy production. It comprises two molecular motors coupled together by a central and a peripheral stalk. Proton flow through the F motor generates rotation of the central stalk, inducing conformational changes in the F motor that catalyzes ATP production. Here we present nine cryo-EM structures of E. coli ATP synthase to 3.1-3.4 Å resolution, in four discrete rotational sub-states, which provide a comprehensive structural model for this widely studied bacterial molecular machine. We observe torsional flexing of the entire complex and a rotational sub-step of F associated with long-range conformational changes that indicates how this flexibility accommodates the mismatch between the 3- and 10-fold symmetries of the F and F motors. We also identify density likely corresponding to lipid molecules that may contribute to the rotor/stator interaction within the F motor. | ||||||||||||||||||||||||||||||||||||||||||
