Comparison with spin-labeling results. (A) Spin-labeling experiments showed that Leu-7 and Ala-10 do not have restricted mobility and are solvent exposed, as opposed to Glu-14 and Thr-18, which have restricted mobility due to interaction with the corresponding residue in the homodimer. This is in line with our model. (B) Surface of EmrE is shown. The labeled residues have been shown to face the lipid by spin-labeling experiments. (C) Contacts to other helices as predicted by our model are corroborated by the spin-label results.
