Publication Abstract from PubMed Multidrug resistance in Gram-negative bacteria arises in part from the activities of tripartite drug efflux pumps. In the pathogen Vibrio cholerae, one such pump comprises the inner membrane proton antiporter VceB, the periplasmic adaptor VceA, and the outer membrane channel VceC. Here, we report the crystal structure of VceC at 1.8 A resolution. The trimeric VceC is organized in the crystal lattice within laminar arrays that resemble membranes. A well resolved detergent molecule within this array interacts with the transmembrane beta-barrel domain in a fashion that may mimic protein-lipopolysaccharide contacts. Our analyses of the external surfaces of VceC and other channel proteins suggest that different classes of efflux pumps have distinct architectures. We discuss the implications of these findings for mechanisms of drug and protein export.
