Experimental PDDF and DH-PDDF profiles for Drew–Dickerson DNA. The blue profile is the PDDF calculated for experimental XS data using GNOM (Fig. S2). The other PDDFs were calculated from labeled PDB structures using the DH-PDDF approach. PDB codes 1bna and 355d (Shui et al., 1998) are crystallographic structures, and PDB codes 1gip, 1duf (Tjandra et al., 2000), 1naj (Wu et al., 2003) and 171d are NMR structures. PDDFs were vertically offset for clarity. The horizontal dotted lines are respective zero baselines. The vertical dashed lines label the experimental PDDF peaks and Dmax. |
