Flagellin protein function
WebBacterial motility relies chiefly on the rotation of a molecular propeller, the flagellar filament, which is constructed from the protein flagellin. Here, flagellin sequence conservation and diversity is examined in the light of the recently determined flagellar filament structure. As expected, the surface-exposed domains are not conserved. Webflagellum, plural flagella, hairlike structure that acts primarily as an organelle of locomotion in the cells of many living organisms. Flagella, characteristic of the protozoan group Mastigophora, also occur on the gametes of algae, fungi, mosses, slime molds, and animals. Flagellar motion causes water currents necessary for respiration and circulation in …
