Figure 5.
Fig. 5. Dimerization surfaces. Stereo view of the
superposition of core domain regions that form the symmetrical
dimer interface upon DNA binding (one-half of the symmetrical
dimer), including the nine structures of Fig. 1 (with the same
color code) and the thermostable mutant T-p53C-R249S (PDB code
2BIO)^38 shown in light blue. The various structural elements
(L2, L3, H1, H1″) and the boundaries of the corresponding
regions (residues 168–195 and 236–250) are indicated. Zinc
atoms are shown by the corresponding colored spheres.
