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.
CC       {ECO:0000256|ARBA:ARBA00024816}.
CC   -!- SUBUNIT: The accessory proteins ExbB and ExbD seem to form a complex
CC       with TonB. {ECO:0000256|ARBA:ARBA00011471}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000256|ARBA:ARBA00004429}; Multi-pass membrane protein
CC       {ECO:0000256|ARBA:ARBA00004429}. Membrane
CC       {ECO:0000256|ARBA:ARBA00004141, ECO:0000256|RuleBase:RU004057}; Multi-
CC       pass membrane protein {ECO:0000256|ARBA:ARBA00004141,
CC       ECO:0000256|RuleBase:RU004057}.
CC   -!- SIMILARITY: Belongs to the exbB/tolQ family.
CC       {ECO:0000256|RuleBase:RU004057}.
