We used oriented solid-state NMR spectroscopy and biochemical cross-linking experiments to demonstrate that the ligand-free membrane protein transporter EmrE forms anti-parallel dimers with different monomer tilt angles relative to the lipid bilayer. Our results also show the subtle conformational changes efflux pumps experience in response to drug binding and emphasize the importance of studying membrane proteins in a fluid bilayer environment.
