Figure 3.

A stereo diagram of the relative orientations of the four helices and the hydrophobic core in the C subdomain. The view, from the top of Fig. 2A, shows the antiparallel orientations of helix-4 and -5 and the perpendicular location of helix-6 relative to the preceding helices. The putative hydrophobic residues from one face of each helix are indicated with their side chains. This figure was prepared by using the ribbons program (34).
