Frequency distribution of Magnesium binding residues in PDB templates and in annotated human sequences. Distribution of the frequency of residues coordinating magnesium ions in the PDB structures (1,341, blue color: Mg is coordinated by the backbone carbonyl oxygen, red color: Mg is coordinated by the lateral side chain) and in the putatively annotated human sequences (3,751, yellow color).
