Superposition of the HP1ß (pdb entry 1KNE) (dark green) and MPP8 Chromo domains (pdb entry 3QO2) (red) in complex with H3K9me3 peptides (light green for HP1 and orange for MPP8). 232 backbone atoms of both domains were superimposed with a root mean square of 0.92 Å using Deep View Swiss PDB viewer 3.7. The distance between the closest atoms of E23 of HP1 and R8 of the peptide is 5.14 Å. In MPP8, E97 approaches R8 more closely, with a distance of only 2.41 Å between the closest atoms.
