Fig. 2.

Ramachandran plots of the guest residues (‘X’) in the GGXGG (G) and AAXAA (A) hosts. Plots have been prepared for all peptides under three environmental conditions: water at 298 K, water at 498 K, and 8 M urea at 298 K. Plots have been normalized to the maximally populated bin of each plot and colored by increasing percentage population from gray to black: 0 = white; 0 < grey < 0.05; 0.05 ≤ green < 0.2; 0.2 ≤ blue < 0.4; 0.4 ≤ red < 0.8; 0.8 ≤ black.
