Figure 4.

Differences in the structure of K₂ in free and SDS-bound states. (A) Ramachandran plots of all residues in the final ensemble of 100 structures for K₂ alone (left) and K₂ in the presence of SDS (right). (B) Fraction of α-helical structures on a per-residue basis for K₂ alone (black line) and K₂ in the presence of SDS (red line). (C) Fractional contact plot map of the final 100 structures. Residues are said to be in contact if a heavy atom of one residue is within 6 Å of another heavy atom. The fractional color scale is shown to the right of the map. The map above the diagonal represents the results for K₂ alone and that below the diagonal represents the results in the presence of SDS. (D) Radius of gyration of the final 100 structures, shown as a histogram plot, for K₂ alone (black bars) and K₂ in the presence of SDS (red bars). To see this figure in color, go online.
