Protein attributes

Sequence length	552 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	The M ring may be actively involved in energy transduction.
Subunit structure	The basal body constitutes a major portion of the flagellar organelle and consists of four rings (L,P,S, and M) mounted on a central rod. The M ring is integral to the inner membrane of the cell and may be connected to the flagellar rod via the S ring. The S (supramembrane ring) lies just distal to the M ring. The L and P rings lie in the outer membrane and the periplasmic space, respectively.
Subcellular location	Cell inner membrane; Multi-pass membrane protein. Bacterial flagellum basal body.
Sequence similarities	Belongs to the fliF family.
