Figure 2: Experimental electron density. a, F[Se] - F[native] difference density (contoured at 4 ) in the EcClC P2[1]2[1]2[1] crystal form superimposed on an carbon trace of the EcClC subunit viewed from outside the cell. Side chains of methionine residues are shown in stick representation with the position of the Se atom indicated by a green sphere. The difference Fourier map was calculated to 4.0 Å and averaged over the six subunits in the asymmetric unit. b, Electron density map from the StClC P2[1] crystal form at 3.0 Å resolution, contoured at 1 . The map was calculated from native amplitudes and solvent-flattened, averaged phases. The refined structure is shown as a stick model. Figures 2 -6 were prepared with DINO (http://www.dino3d.org).
