Fig. 6

Potentials of mean force (kcal/mol) as a function of slide (see Additional file 1: Figure S1) and number of protein contacts for the Drew-Dickerson dodecamer at 20% (a), 30% (b), 40% (c) protein concentrations, and for the GC-rich dodecamer at 20% (d), 30% (e), 40% (f) protein concentrations from the simulations. A contact is defined when the minimum distance between the heavy atoms of crowder proteins and DNA phosphate groups is less than 5 Å. Solid and dashed lines indicate the slide and x-displacement values for canonical B- and A-forms, respectively. See Additional file 1: Table S5 for uncertainties
