FIGURE 2   Inverse alignment of cluster 1 from Cv (purple) and DaI (white) with cluster 2 from Pa (dark blue), AvI (red), and Bs (light blue). The protein backbones and the extra cysteines are shown as licorice models (white side chain is completely within the other four) while the cluster is represented as in Fig. 1. This figure was generated using MOLSCRIPT (Kraulis, 1991) and Raster3D (Merritt and Murphy, 1994).
