“Evidence for the hook supercoiling mechanism of the bacterial flagellum”

【Significance】
Bacterial flagellar hook supercoiling mechanism

The bacterial flagellar hook is a short, highly curved tubular structure connecting the flagellar motor with the helical filament acting as a propeller to function as a universal joint to transmit motor torque to the filament regardless of its orientation. The highly curved form is part of a supercoil as observed in the polyhook structure. The essential role of the outermost domain D2 of the hook protein in the supercoiling mechanism is revealed by its deletion that made the polyhook straight.
