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  ALA-144   SER-145  8.1 8.4 -2.4 4.3 153.7 152.5 9.6  SER-145   GLY-146  8.9 9.2 7.9 -8.2 79.6 81.7 -24.9  GLY-146   ARG-147  12.3 12.7 7.7 -1.2 58.0 58.4 -16.0 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
