Figure 2.
Overlay of the Ca^2+ binding sites of WT-CBD1 and E454K-CBD1.
E454K-CBD1 is shown as a blue drawing, and Ca^2+ ions are
depicted as green spheres. Ca^2+-coordinating residues are
displayed as sticks colored by atom type (Cα is yellow).
Relevant metal ion coordinations and charge pairs of E454K-CBD1
are shown as black dotted lines. WT-CBD1 is shown as a gray
drawing, and equivalent residues are displayed as sticks colored
by atom type. Ca^2+ ions are numbered according to Ref. 5.
