The Basal Body of Bacterial Flagella

  • M. L. DePamphilis

Abstract

The bacterial flagellum is composed of three structurally defined parts: the filament, the hook, and the basal body. The filament is a long, narrow helical structure composed of the protein flagellin, and comprises approximately 98 per cent of the flagellum’s length. At the proximal end of the filament is a hook-shaped structure whose morphological, chemical, and serological properties are distinct from the filament (Abram et al., 1970; Dimmit and Simon, 1970a; Lawn, 1967). This “hook” enters the cell wall where it is attached to a complex structure called the basal body. The basal body is firmly bound into the cell envelope and is the only part of the flagellum inside the cell wall.
