Figure 4.
Figure 4. Stereoview of the electron density. Parts of the central b sheet A (strands 3A, 4A, 5A and 6A, right to left, and turn s5As4A) are superimposed with the final 2F[o]-F[c] electron-density map contoured at 0.8s. The atoms are colored by type: blue, carbon; cyan, nitrogen; and red, oxygen. The figure was made with the program BobScript [49].
