Figure 1.
(a) Structure of 3MBT bound to an H4K20me2 peptide (residues 17–25). H4K20me2 peptide is shown in red and the dimethyllysine is shown as a stick model. (b) Sequence alignment of MBT2, MBT1 and MBT3. Red, identical; blue, conserved; dots, lysine-binding pocket residues. (c) Superimposition of the three MBT repeats in 3MBT. Residues forming the lysine-binding pocket are shown as green sticks, and Phe256 from MBT1 and Arg467 from MBT3 are colored pink and blue, respectively. H4K20me2 peptide is shown as yellow sticks.
