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  THR-70   MET-71  16.0 15.7 -1.2 15.7 50.4 36.3 -6.9  MET-71   MET-72  14.4 15.2 1.1 -6.0 136.3 124.3 1.6  MET-72   ALA-73  15.1 15.5 6.0 -17.0 76.5 72.1 1.5  ALA-73   ARG-74  14.0 13.2 36.2 -39.1 92.5 98.7 0.3  ASP-78   THR-79  6.2 7.7 -18.4 -21.9 15.3 44.3 33.2  THR-79   ASP-80  7.5 10.1 158.2 169.1 96.0 103.2 -14.5  ASP-80   SER-81  9.2 8.3 63.0 -11.8 83.0 103.0 -2.2  SER-81   GLU-82  6.5 6.2 -122.6 -14.6 31.6 18.5 106.9  GLU-82   GLU-83  4.5 4.7 2.2 18.3 136.3 128.2 -16.0 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
