Bacterial flagellumBacterial flagellum basal body

Definition

The basal body of a bacterial flagellum is a rod and a system of rings embedded in the cell envelope. Gram-negative flagella usually have an L ring in the plane of the lipopolysaccharide in the outer membrane, a periplasmic P ring in the plane of the peptidoglycan around the flagellar rod and a MS ring that is located within and above the cytoplasmic membrane. A C ring extends into the cytoplasm. The rod is a major component of the flagellar basal body and it spans the bacterial periplasm. The L and P rings are not found in Gram-positive bacteria.
