Extended Data Fig. 3: Comparison between in situ stator complex and the purified stator components.
From: Molecular mechanism for rotational switching of the bacterial flagellar motor
a, Structure of purified MotA complex from A. aeolicus resolved by single particle EM (EMD 3417)27. b, The in situ stator complex in the ∆cheX motor has a bell-shaped structure embedded in the inner membrane (IM) and a periplasmic domain. The top part of the periplasmic domain matches well with the crystal structure of the S. enterica MotB periplasmic domain (PDB 2ZVY)28 (middle panel). The bell-shaped structure has similar size and shape as the structure of EMD 3417 (right panel). c, The in situ stator complex in the ∆cheY3-Class-2 motor is similar to that in the ∆cheX motor.
