Theoretical scattering curves for the four proteins, PDB codes 1B0P (solid line), 1CX8 (dashed line), 1FCE (dotted line), and 1QJ2 (dashed-and-dotted line), predicted to share a high degree of secondary structure homology with ES-62. The curves were calculated from the coordinates of the homologous region of the proteins using the software CRYSOL (Svergun et al., 1995). The homologous regions of 1B0P and 1CX8 have similar solution shapes; 1QJ2 is slightly different and 1FCE is very different.
