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  ILE-85   ARG-86  3.7 6.0 178.6 -66.3 29.6 69.6 53.8  ARG-86   GLU-87  1.2 6.3 19.1 -64.2 92.2 7.4 -16.6  GLU-87   ALA-88  3.5 4.7 -136.8 -99.0 103.4 106.0 32.3  ALA-88   PHE-89  6.1 5.9 126.4 -9.1 17.9 27.0 -154.3  PHE-89   ARG-90  5.5 5.2 -156.7 -48.0 123.1 117.0 105.2 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
