Figure 4.
Fig. 4. The CA7 Fab binding site in D5. CA7 Fab is shown as a surface representation colored in wheat (heavy chain) and light blue (light chain) bound to monomeric D5 shown as a magenta ribbon, with indicated side chains in the AA loop at the center of the epitope as black sticks. Dimeric D4 and D5 are shown as ribbons with a cyan monomer and a yellow monomer superimposed on monomeric D5. The inward-pointing Leu residues of -strand E of the cyan monomer are shown as blue sticks.
