Extended Data Fig. 5: Motor structures in constantly running ∆cheY3 cells.
From: Molecular mechanism for rotational switching of the bacterial flagellar motor
a, A medial cross-section of an averaged structure in ∆cheY3 B. burgdorferi cell. b, c, Cross-sections show the stator ring and the C-ring, respectively. d, Focused structure of the C-ring (unrolled along the central rod). Two distinct classes in the ∆cheY3 cells are named as ∆cheY3-Class-1 e-h, and ∆cheY3-Class-2 i-l. Class-1 and Class-2 account ~45% and ~55% of all the ∆cheY3 motors we used for current work, respectively. The stator structures in Class-1 and Class-2 f and j, are quite similar, while the C-ring subunits (compare h with l) are tilted in different directions.
