RT "Genome sequence of the nitrite-oxidizing bacterium Nitrobacter vulgaris
RT strain Ab1.";
RL Submitted (FEB-2017) 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.
CC {ECO:0000256|ARBA:ARBA00024816}.
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}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
