AcrAB-TolC is the most important multidrug efflux pump system of Gram-negative bacteria, responsible for their resistance to lipophilic and amphiphilic drugs. In this work, a molecular graphics study of the pump components AcrB and TolC, 16 β-lactam antibiotics and 7 other substrates, as well as of AcrB-substrate complexes, was performed in order to give a mechanistic proposal for the efflux process at molecular level. AcrAB-TolC is a proton-dependent electromechanical device which opens to extrude drugs from the bacterial periplasm and perhaps cytoplasm, by means of a series of structural changes within the complex and its components AcrA, AcrB and TolC. These changes are initiated by protonation and disruption of salt bridges and certain ...
