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  LYS-181   TYR-182  3.0 3.0 6.4 -8.0 66.2 65.4 -28.1  TYR-182   ILE-183  6.0 6.0 10.3 -4.5 8.8 11.6 62.3  ILE-183   THR-184  6.1 6.1 -7.7 2.2 113.3 111.7 4.3 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
