Figure 4
DNA-(Slr1738) 2 complex structure properties. A) 3D structure of DNA-(Slr1738)2 complex showing six contact regions between the protein (in grey) and the DNA molecule (in cyan). For each monomer, the predicted contact regions are the loop between H1 and H2 (in orange), the helix H4 (in red) and the loop between S1 and S2 (in yellow). B) Helical wheel representation of the recognition helix (H4) of the monomer A. Three faces with different properties are presented. In soft pink are shown the hydrophobic residues turn toward the protein. In dark pink are shown the small residues facing the DNA strand 2 and in red are represented the large and charged residues in interaction with the DNA strand 1. Hydrophilic residues are present as circles, hydrophobic residues as diamonds and potentially positively charged as pentagons http://rzlab.ucr.edu/scripts/wheel/wheel.cgi.
