Cryo-EM structures provide insight into how E. coli F1Fo ATP synthase accommodates symmetry mismatch
F1Fo ATP synthase consists of two coupled rotary molecular motors: the soluble ATPase F1 and the transmembrane Fo. Here, the authors present cryo-EM structures of E. coli ATP synthase in four discrete rotational sub-states at 3.1-3.4 Å resolution and observe a rotary sub-step of the Fo motor cring t...

| Sumario: | F1Fo ATP synthase consists of two coupled rotary molecular motors: the soluble ATPase F1 and the transmembrane Fo. Here, the authors present cryo-EM structures of E. coli ATP synthase in four discrete rotational sub-states at 3.1-3.4 Å resolution and observe a rotary sub-step of the Fo motor cring that reveals the mechanism of elastic coupling between the two rotary motors, which is essential for effective ATP synthesis. |
