Figure 4. The intermolecular contacts between the Mrf2 ARID domain and DNA.
(a) Summary of the contacts observed between the protein and DNA. Dashed lines indicate intermolecular van der Waals interactions. Arrows indicate intermolecular hydrogen-bond interactions with arrowheads denoting the hydrogen bond acceptors. (b) Detailed view of the protein-DNA interface. The amino acid residues involved in DNA-binding are from loops L1 and L2, and helices H4 and H5.
