Bending Residue Dihedral Analysis

Residue i Residue i+1 Distance of hinge axis to residue i in conformer 1 (A) Distance of hinge axis to residue i in conformer 2 (A) Change in psi (i) (deg) Change in phi (i+1) (deg) Angle of psi(i) axis to hinge axis conformer 1 (deg) Angle of psi(i) axis to hinge axis conformer 2 (deg) Percentage Progress  GLN-1137   ALA-1138  3.4 2.8 -14.6 18.5 78.6 79.2 7.1  ALA-1138   ASP-1139  6.6 6.0 -13.1 19.3 81.8 90.4 -17.1  ASP-1139   TYR-1140  8.0 7.7 -10.9 7.4 131.0 140.2 -3.3 Graph shows rotational transition at bending residues and can be used to identify hinge bending residues. Probably only informative for interdomain rotations greater than 20 degrees
