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  ASN-192   LEU-193  3.9 4.4 13.4 -25.0 60.1 61.0 -2.7  LEU-193   ALA-194  0.4 0.9 16.3 4.5 6.9 11.5 122.4  ALA-194   SER-195  2.0 2.0 -17.5 8.7 120.4 130.6 -33.9  SER-195   LYS-196  3.3 2.8 -4.6 21.1 90.4 81.9 2.7  LYS-196   SER-197  3.6 3.6 2.9 5.8 57.3 64.0 20.8  SER-197   ALA-198  5.2 5.5 -3.0 -3.9 49.7 39.7 18.6  ALA-198   GLU-199  7.5 7.4 10.4 4.2 115.1 114.7 -51.1 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
