Figure 3
Salt bridges and hydrogen bonds at the derCD23–Fc∊3-4 interface of the triclinic crystal form. The four salt bridges shown in red, with additional hydrogen bonds shown in green, were seen in the orthorhombic crystal form. A further hydrogen bond present in three of four molecules is shown in yellow. Also depicted is an enlarged view of a region of the interface showing the additional Arg440–Asp227 salt bridge and hydrogen bond (in purple) found only in the triclinic crystal form. Lightly coloured residues are from the A:G interface of the orthorhombic crystal form (PDB entry 4ezm ).
