Figure 1. The 2F[o] - F[c] electron density map for the crystal structure of PR[V82A]/SQV. The major conformation is colored by atom type and the minor one is in magenta. (A) Saquinavir (contoured at 2.2 level). (B) Residues 79-82 (contoured at 1.8 level). (C) Catalytic site (contoured at 1.8 level). Asp25 and 25 are shown with the hydroxyl group of SQV.
