Figure 2. Structure-based sequence alignment of RAD against close structural homologues identified by DALI.[38] Only the sequences of the polypeptides present in the PDB entries are displayed. The positions of -helices are indicated by red shading and the locations of the W,W,W motifs are boxed. EH has a Phe in the third position according to the structural alignment, although the adjacent residue is a Trp (also boxed). Residues showing large chemical shifts in ARR10-B upon binding DNA are indicated with blue bars. Residues that contact DNA in the crystal structure of EH are also shown as bars: blue bars representing interactions with the phosphate backbone and green bars indicating interactions with the DNA bases.
