Comparisons of the crystal structures with the NMR structure of HP67. Mol B of HP67 (orange) is overlaid with the averaged NMR structure (blue) in (a) in ribbon representation. The backbones of Mol X (red), Mol A (magenta), Mol B (orange) and the averaged NMR structure (blue) are aligned in (b) for the entire sequence and in (c) for the C-terminal subdomain, with Phe47, Phe51 and Phe58 labelled. Graphics were created by MOLMOL (Koradi et al., 1996 ▶).
