Correlation coefficients between conformational deviation along each PC axis and physical indicator. The radius of gyration (Rg) for PCall1, structural symmetry related to the N-terminal and C-terminal halves (D sim ) for PCall2, a simple indicator of β-hairpin (Dmn+mc) and Dmn+mc/end-to-end distance (D end ) for PCall3, and the radius of gyration ( mid Rg) around the midpoint of the segment for PCall4 were used in these analyses. Correlation coefficients were calculated at every 10 residues of 10–50 residues.
