Abstract	The resistance of cells to many drugs simultaneously (multidrug resistance) often involves the expression of membrane transporters (Mdrs); each can recognize and expel a broad spectrum of chemically unrelated drugs from the cell. Despite extensive research for many years, the actual mechanism of multidrug transport is still largely unknown. In addition to general questions dealing with energy coupling, the molecular view of substrate recognition by Mdrs is generally obscure. This mini-review describes structural and functional properties of the Escherichia coli Mdr, MdfA, and discusses the possibility that this transporter may serve as a model for studying the multidrug recognition phenomenon and the mechanism of multidrug transport.
