Figure 8. (a) A stereoview of the cis peptide bond between Glu118 and Leu119 is shown in a refined 2F[o] -F[c] simulated annealing omit map contoured at 1.0s in which the contents of the Figure were omitted from the structure factor calculations. (b). A stereo view showing an F[o] -F[c] difference density map contoured at 3.0s for the peptide bond between Glu118 and Leu119 refined in the trans conformation. The aligned cis conformation is shown in gold for reference. (c) The cis peptide bond and surrounding residues are shown, in stereo, as ball-and-stick models. The amino acid residues interacting with Glu118 and Leu119 are labeled. The helix between Phe170 and Asp162 is shown as a green ribbon.
