Fig. 8. : Protein motion vs. DSSPcont. Protein motion measured by the order parameter 1-S2 is plotted against the DSSPcont assignment grouping helices (GHI) and strands (EB). The points are averages over three consecutive residues and the line is a binned average of helix/strand assignments. Using one set of coordinates from an ensemble of NMR models the continuous DSSP assignment reproduces the segments in a protein that experimentally had a high degree of motion due to thermal fluctuations in water. Note: data as in Fig. 7.
