WebRotary Motor. For the F1 rotary motor, the overall reaction is the hydrolysis of ATP that is the substrate and the products are ADP and Pi. ... When one or more of the motors rotate CW, the corresponding flagella unbundle and the bacterium stops and spins in place. The bacterial flagellum is a supramolecular motility machine consisting of the basal body as a rotary motor, the hook as a universal joint, and the filament as a helical propeller. Intact structures of the bacterial flagella have been observed for different bacterial species by electron cryotomography and subtomogram averaging.

A Third Rotary Motor Has Now Been Found in Bacteria

The three types of flagella are bacterial, archaeal, and eukaryotic. The flagella in eukaryotes have dynein and microtubules that move with a bending mechanism. Bacteria and archaea do not have dynein or microtubules in their flagella, and they move using a rotary mechanism. Other differences among these three types are: WebNational Center for Biotechnology Information
