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  ARG-74   LYS-75  6.6 6.8 -19.2 -77.2 103.9 93.1 -11.3  LYS-75   MET-76  5.3 3.7 137.6 -36.6 118.9 135.8 -55.9  MET-76   LYS-77  2.9 4.5 155.6 22.7 143.8 150.9 89.9  SER-81   GLU-82  6.8 7.2 -105.8 78.7 102.5 88.5 -2.0  GLU-82   GLU-83  10.4 9.6 -26.7 4.7 37.1 39.5 6.7 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
