Figure 2.
Figure 2. Ramachandran diagram, calculated using the program of [Laskowski et al 1993], showing the backbone conformational angles for the four Cro monomers. Glycine residues are shown as triangles, non-glycine residues as squares. Ser60 is toward the carboxy terminus of the molecule at the point where the electron density becomes weak, indicative of disorder.
