From: ConSole: using modularity of Contact maps to locate Solenoid domains in protein structures
Solenoid contact patterns. (a) The correlation matrix M 1 determined for template matching the contact map of PDB 1DFJ-Chain I determined with the solenoid pattern (b). Bright regions indicate high correlation values [0;1], while dark regions indicate low [−1; 0] correlation values. (b) The solenoid pattern to generate M 1 and (c) the non-solenoid pattern to generate M 2 used for template matching. (d) Plot of the correlation coefficients determined for residue 75 in chain I of 1DFJ. Twenty correlation coefficients were collected around the main diagonal [(75,55); (75,95)] from M 1 and merged with 20 coefficients from M 2 from the same positions. (e) Coefficients determined for residue 81 in chain B of the globular structure from 1QGC. Correlation features determined for solenoid residues have smoother profiles compared to rather noisy features of globular proteins. Peak correlation values also differ for the solenoid/non-solenoid combinations, respectively.
