Protein
Multidrug efflux pump subunit AcrA
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. This subunit may act as an adapter protein that links AcrB and TolC stably together. It is elongated in shape, being long enough to span the periplasm.
Similarity
Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.
