Flagellar motor switch protein
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: WebApr 3, 1998 · A ring of about 10 membrane particles known as studs surround each flagellar motor. These probably sit in the L-shaped shelf made by the M and C rings. Figure 1 The Bacterial Flagellum. ... Because it connects the switch proteins to the drive shaft, FliF (an M-ring protein) must be part of the rotor.
