MdfA is a prototypic secondary multidrug transporter from Escherichia coli, which recognizes and exports a broad spectrum of structurally and electrically dissimilar toxic compounds. Here we review recent studies of MdfA, which, on the one hand, provide advanced understanding of certain aspects of secondary multidrug transport, and, on the other, address major mechanistic questions, some of which remain to be elucidated. Using biochemical, genetic, and physiological approaches, we have revealed several surprisingly promiscuous properties of MdfA including its multidrug recognition capacity, proton recognition determinants, aspects of energy utilization, and physiological role.
