General Information of Binding Target of SBP (BTS) (ID: ST00129)
BTS Name
Multidrug efflux pump subunit AcrB
Synonyms
AcrAB-TolC multidrug efflux pump subunit AcrB; Acridine resistance protein B
BTS Type
Protein
Family
Resistance-nodulation-cell division (RND) (TC 2.A.6) family
Gene Name
acrB
Organism
Escherichia coli (strain K12)
Function
AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates.; (Microbial infection) Involved in contact-dependent growth inhibition (CDI), acts downstream of BamA, the receptor for CDI. Its role in CDI is independent of the AcrA-AcrB-TolC efflux pump complex.
