Figure 4.
Fig. 4. Stereo comparison of 2.5 Å di-Zn-DF1
structure with designed model. The superposition of the crystal
structure symmetric dimer (green) and the designed model (gray)
shows the liganding Glu and His residues. Note that the
dimetal-binding site is nearly identical between the model and
the crystal structure. However, conformation of the Tyr-2 and
Trp-42 side chains in the crystal structure differs markedly
from that in the design.
