Figure 3

Crystal structures of wild-type GB1 (1, PDB 2QMT)9b and three analogues with modified backbone in the helix (2), loops (3), or turns (5). Root mean square deviation (rmsd) values are calculated for overlay of Cα atoms between 1 and the indicated analogue. Unnatural residues are shown as spheres; the coloring scheme for proteins 2, 3, and 5 matches Figure 1C.
