OrganismHelicobacter pylori (strain ATCC 700392 / 26695) (Campylobacter pylori) [Reference proteome] [HAMAP]
Taxonomic identifier85962 [NCBI]
Taxonomic lineageBacteriaProteobacteriaEpsilonproteobacteriaCampylobacteralesHelicobacteraceaeHelicobacter

Protein attributes

Sequence length145 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Involved in the TonB-dependent energy-dependent transport of various receptor-bound substrates. Protects ExbD from proteolytic degradation and functionally stabilizes TonB By similarity.

Subunit structure

The accessory proteins ExbB and ExbD seem to form a complex with TonB By similarity.

Subcellular location

Cell inner membrane; Multi-pass membrane protein.

Sequence similarities

Belongs to the ExbB/TolQ family.

Sequence caution

The sequence AAD08381.1 differs from that shown. Reason: Erroneous initiation.
