Figure 4.

NMR solution structures of (A) CjCBM5 (Protein Data Bank ID:6Z40) and (B) CjCBM73 (Protein Data Bank ID:6Z41). The figures show backbone representations of the 20 conformers with the lowest CYANA target function (left), a cartoon representation of the structure with the lowest target function (center), and a view of the binding surfaces (right). The cartoon representations also display the secondary structure elements as well as aromatic residues of the putative binding surface. Disulfide bridges (residues 253–306 in CjCBM5 and 340–396 and 366–372 for CjCBM73) are highlighted in orange. His tags added for purification purposes (see Experimental procedures section) are not shown.
