Figure 8

Examples of protein/DNA interactions. (A) Structure of human centromere protein B (CENP-B) binding to DNA CENP-B box (PDB code 1HLV, Tanaka et al., 2001). The image highlights contacts between arginine 125 (chain A, green) in PB m (regular helix) and cytosine 15 (chain B, red) in ntC 41. (B) Details of methionine repressor protein (MetJ) binding to DNA metbox (PDB code 1MJQ, Garvie and Phillips, 2000). The same PB m and amino acid residue (arginine 40 in chain H, green) is in contact with guanine 2 (chain K, red) in NtC 13. Visualization was created by the program PyMOL (http://www.pymol.org, Delano, 2013).
