RL   Submitted (NOV-1999) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Assembles around the rod to form the L-ring and probably
CC       protects the motor/basal body from shearing forces during rotation.
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. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250}. Bacterial flagellum
CC       basal body {ECO:0000250}.
