Figure 3.

(a) Stereo diagrams of the 13 superimposed α₃D structures are shown with the hydrophobic core residues depicted in red and W4 and Y45 in yellow. The structures were aligned by using only the backbone atoms (residues 4–21, 24–45, and 51–70). The figure was generated by using the program molmol (58). (b) Stereo display of a ribbon diagram with the hydrophobic residues in red and W4 and Y45 in yellow of the lowest energy structure of α₃D. The figure was created by using the programs molscript (59) and raster3d (60).
