Fig. 3. : DSSPcont assignments for DSSP states. For each of the eight default DSSP states (x-axis), we compiled the average continuous assignment (letter height proportional to average) for both (a) the X-ray and (b) the NMR data sets. The DSSP states generally remained the same. Only the 310-helix and b-bridge states were markedly changed, but all changes occurred within their respective class (helix {GHI} and strand {EB}). X-ray and NMR data sets yielded similar results. Note that the low-counts of the 'I' state result in large variations. The letters shown represent G: 310-helix, H: a-helix, I: p-helix, T: turn, E: extended b-strand, B: b-bridge, S: bend, L: other/loop.
