Detection of Ring Structure and Its Flexibility in Periplasmic Region of FliL, Bacterial Flagellar Stator-Associate Protein, in Marine Vibrio.
Analysis of oligomeric organization and structural plasticity of the periplasmic domain of polar-flagellum FliL from Vibrio alginolyticus and compared with detergent-solubilized full-length pofFliL suggests that such plasticity enables FliL to act as an adaptable scaffold for stator engagement and mechanosensitive remodeling of the motor.
