FIGURE 7

The free energy landscape for peptide K19 at 275 K, along with representative structures obtained from cluster analysis of the ensemble. X and Y axes represent the first 2 principle components. Relative free energy values (in kcal/mol) are represented by color as indicated by the legend. Representative structures for each basin are shown. The colors of the structures reflect secondary structure type: alpha helix – purple, extended beta – yellow, turn – cyan, coil – orange. Only lysine side chains are shown. The populations of the clusters are shown in parentheses.
