Figure 8
A fragment of PDB structure 3e0k around the site of a rather improbable Na+ ion. The B factors (Å2) of the Na+ ion and selected neighboring atoms are shown in parentheses and the distances (in Å) of two close O and two H atoms are also shown. The 2mFoDFc map (blue) is contoured at 1.5σ and the mFoDFc map at ±2.5σ (positive contours, green; negative contours, red).
