RT   motor of a marine bacterium.";
RL   J. Bacteriol. 179:5104-5110(1997).
CC   -!- FUNCTION: PomA and PomB comprise the stator element of the flagellar
CC       motor complex. Required for rotation of the flagellar motor. Probable
CC       transmembrane proton channel (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Each stator complex is composed of 4 PomA and 2 PomB subunits.
CC       2 A subunits and 1 B subunit are thought to form a single ion channel,
CC       so that each stator complex contains two channels (By similarity).
CC       {ECO:0000250}.

CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the MotA family. {ECO:0000305}.
