Figure 1.
Figure 1. Electron Density Map of the Region between Helix C and Strand 5The |F[o]|exp(iφ^ave) electron density map is contoured at 1.5 σ and superimposed upon the refined model. |Fo| and φ^ave are the observed amplitudes, and the calculated phases after NCS averaging with RAVE ([23]), respectively. In this map, the turn between helix C and strand 5 (residues 80–85) is stabilized by a solvent molecule or a cation. The refined model is superimposed on the density as a wire model. A water molecule and the unidentified solvent/cation molecule are shown as magenta spheres.
