Figure 5.

Matrix of the static correlation of secondary structure I_ij (Eq. 5). The modular pattern suggests that the interactions responsible for secondary structure formation are present between the homopolymer segments of the protein ssG. The cartoons are shown to illustrate the secondary structure elements having the highest correlations. Abbreviations: H = Ala²³–Ala³⁷ for the poly-Ala and S1 = Thr¹–Thr⁹, S2 = Thr¹²–Thr²⁰, S3 = Thr⁴⁰–Thr⁴⁷, and S4 = Thr⁵⁰–Thr⁵⁶ for the poly-Thr.
