CC   -!- FUNCTION: Involved in the TonB-dependent energy-dependent transport of
CC       various receptor-bound substrates. Protects ExbD from proteolytic
CC       degradation and functionally stabilizes TonB (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the ExbB/TolQ family. {ECO:0000305}.
