Interaction between C6 and the FN recombinant fragment formed by the type III repeats B and 8.

A) Schematic representation of the main interactions between the two proteins. The type III domains B and 8 are drawn as green ribbons, the scFv C6 is orange. Residues involved in the binding are reported as sticks, hydrogen bonds between amino acids are shown as dotted black lines. B) Residues of the scFv and of the type III repeats B and 8 that interact. The distances are displayed. C) Representation of the interaction between the type III domains B-8 (green surface) and the scFv C6 (orange surface).
