Figure 2.
Fig. 2. Stereo diagrams of electron density maps. (A) 2F[o]
– F[c] map in blue and F[o] – F[c] map in red when the
substrate model refined is of a regular peptide. The peptide
bond is in the negative density of the F[o] – F[c] map. (B)
2F[o] – F[c] omit map overlaid with the three models: regular
peptide model (cyan), tetrahedral hydrated peptide model
(brown), and cleaved peptide model (atomic color). Omit density
for P1, P3, P1', and P3' residues defines the single orientation
of the substrate.
