Bacterial flagellum structure. Cutaway artwork showing the internal structure of the flagellum in bacteria,with examples of bacteria and their flagella at lower right. The flagellum,used for locomotion,is a protein filament designed to rotate like a propeller and move the bacterium forward. The base of the flagellum (seen here) is composed of a series of rings that allow this helical movement. Surrounding the rings are rod-like units called stators. The entire unit can reach speeds of 200-1000 revolutions per minute. The hook (upper left) is the sharp bend in the flagellum where it leaves the cell. Some bacteria have several flagella | |
