Multidrug efflux pumps adversely affect both the clinical effectiveness of existing antibiotics as well as the discovery process to find new ones. In this chapter, we summarize recent advances in structural and functional analyses of multi-component efflux pumps from Gram-negative bacteria with the focus on transporters belonging to the Resistance-Nodulation-cell Division superfamily. The unquestionably significant impact of these pumps on the effectiveness of antibiotics in clinical settings and their emerging role in bacterial pathogenesis makes them attractive targets for inhibition. We discuss modes of inhibition and current efforts to develop effective inhibitors of multidrug efflux pumps read more ...
