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  4.1 6.4 162.9 -52.3 28.8 66.7 56.7  ARG-86   GLU-87  1.6 6.5 24.7 -71.5 90.6 8.6 -19.9  GLU-87   ALA-88  3.1 5.0 -137.0 -101.4 104.5 110.2 39.6  ALA-88   PHE-89  5.9 6.1 95.5 16.1 18.2 25.2 -162.2  PHE-89   ARG-90  5.4 4.9 -172.4 -62.4 124.4 119.1 83.2 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
