OX   NCBI_TaxID=75985;
RN   [1]

RA   Graham M.R., Lo R.Y.C.;
RL   Submitted (JUN-1996) to the EMBL/GenBank/DDBJ databases.
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   -!- SUBUNIT: The accessory proteins ExbB and ExbD seem to form a complex
CC       with TonB. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
CC   -!- SIMILARITY: Belongs to the ExbB/TolQ family. {ECO:0000305}.
