Architecture of the Vibrio-specific T ring. (A) The Vibrio motor structure with different domains is highlighted in a 3D surface rendering. (B) Crystal structures of MotY and FlgT were fitted into the map of the T ring and the small portion of the H ring, respectively. (C) Outer membrane and its associated flagellar components were removed to have a better view of the T ring. (D) A top view of the Vibrio motor shows the O ring, the hook, and the OM. (E) Another top view after removing the OM-associated structures shows the CM, the hook, and the T ring. (F) Crystal structures of FlgT and MotY fit well into the T ring.
