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  LEU-179   GLN-180  7.5 8.1 -85.3 120.1 127.8 104.2 138.0  GLN-180   ARG-181  6.6 6.0 -97.6 122.5 74.2 60.3 -82.7  ARG-181   THR-182  8.4 8.2 -31.7 13.7 37.1 62.6 69.8  THR-182   ASP-183  7.4 6.9 6.4 -19.2 119.6 121.0 41.6  ASP-183   ALA-184  9.7 9.0 28.2 -22.3 109.0 103.3 -31.6 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
