Caption
States 1 to 3 indicate main pauses and States 1' to 3' indicate sub-pauses. The main pauses are structures in which the rotor rotates by 120 degrees, but in State 3, the angle deviated -10 degrees. In addition, the sub-pauses deviated +13° in State1', +32° in State2', and +28° in State3'. (A) Overall structure of EhV-ATPase. (B) Positional relationship between the rotor terminal subunit “d” and the c-ring. Subunit “d” (red “+” indicates the position of the centroid) is in contact with the c-ring at a position distant from the center of the c-ring (black “+”). As a result, the rotor stirs the c-ring as indicated by the yellow line in (A). (C) Structural interference between rotor-end subunit “d” and stator subunit “a”.
