CC   -!- FUNCTION: The M ring may be actively involved in energy transduction.
CC       {ECO:0000250}.
CC   -!- SUBUNIT: The basal body constitutes a major portion of the flagellar
CC       organelle and consists of four rings (L,P,S, and M) mounted on a
CC       central rod. The M ring is integral to the inner membrane of the cell
CC       and may be connected to the flagellar rod via the S ring. The S
CC       (supramembrane ring) lies just distal to the M ring. The L and P rings
CC       lie in the outer membrane and the periplasmic space, respectively (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}. Bacterial flagellum basal body {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the FliF family. {ECO:0000305}.
