CC   -!- FUNCTION: Involved in the TonB-dependent energy-dependent transport of
CC       various receptor-bound substrates. {ECO:0000250}.
CC   -!- SUBUNIT: The accessory proteins ExbB and ExbD seem to form a complex
CC       with TonB. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Single-pass
CC       type II membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ExbD/TolR family. {ECO:0000305}.
