resistance-nodulation-cell division (RND) (TC 2.A.6) family

DESCRIPTION

Also known as ACRB_ECOLI, acrB, acrE. 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. Homotrimer, with large domains that extend into the periplasm, interacts with AcrA and TolC. AcrA may be required to stably link this protein and TolC. Interacts with AcrZ. Part of the AcrA-AcrB-AcrZ-TolC efflux pump.
