WebThe bacterial flagellum is an apparatus of motility commonly found among motile species. The flagellum is a supramolecular structure composed of about 20 protein components and divided into three substructures: the filament, the hook and the basal body. The filament is a helix, which takes on several distinct forms under various conditions. WebFlagellin is a structural protein of the flagellum, a surface filament dedicated to bacterial motility. The flagellar filament is composed of as many as 20,000 subunits of flagellin. In pathogenic bacteria, flagella and chemotaxis machinery contribute to virulence. 1 The size of flagellins ranges from 250 to 1250 amino acids depending on the bacterial species. 2 …
