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-237   ARG-238  8.5 8.5 1.3 -56.6 109.1 97.1 13.7  ARG-238   THR-239  6.6 5.4 -5.9 -5.3 83.4 35.6 4.8  THR-239   ARG-240  2.9 2.8 -10.3 -74.0 20.1 39.5 67.6  ARG-240   VAL-241  1.6 3.2 -29.2 -160.0 58.9 40.2 -101.2  VAL-241   ARG-242  1.2 1.4 -51.4 -71.7 22.0 24.5 87.6  ARG-242   LYS-243  1.3 1.8 -27.0 24.0 39.2 46.9 3.0  LYS-243   SER-244  0.6 1.2 -9.5 -1.3 35.7 36.6 6.8  SER-244   ILE-245  2.6 2.5 18.3 -16.0 71.9 68.7 -0.3  ILE-245   GLY-246  6.1 6.0 -8.6 -3.5 26.0 29.4 7.7 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
