Figure 3
Quality of the electron-density maps displayed around the octahedral coordination of sodium in the lysozyme structure. 2mFoDFc electron-density maps are shown as light pink mesh contoured at 1σ. The residues coordinating the Na atom (Ser60, Cys64, Arg71 and Ser72) are shown as a magenta stick representation. Waters W3 and W4 are shown as red spheres. The interactions between sodium and its ligands are represented as blue dotted lines.
