Comparative analysis of the intact motor and the purified basal body. (A) Purified S. enterica basal body structure determined by cryo-EM.66 (B) In situ S. enterica motor structure reconstructed by cryo-ET.49 (C) Cartoon model of the S. enterica flagellar motor. (D) The purified B. burgdorferi basal body structure determined by cryo-ET50 is comparable to the MS ring and rod complex of the S. enterica basal body. (E) Intact motor structure of B. burgdorferi.52 The basal body portion is outlined in the intact motor. (F) Cartoon model of the B. burgdorferi flagellar motor. (G) Slice from a cryotomogram of a ΔfliE mutant showing two flagellar motors lacking the filament and hook.50 (H) Averaged motor structure of the ΔfliE mutant. The red arrow indicates that the central channel in the MS ring is closed. (I) Cartoon model of a rodless motor in the ΔfliE mutant. The architecture of the MS ring in the B. burgdorferi motor is similar to that of the MS ring in S. enterica.67
