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  ASP-219   LYS-220  7.1 8.0 -10.0 -5.9 113.4 121.3 -40.2  LYS-220   TYR-221  3.6 4.5 2.7 4.6 111.1 107.6 -15.6  TYR-221   GLU-222  5.5 5.0 -44.3 11.8 106.9 98.7 -24.8  GLU-222   GLU-223  8.7 8.8 15.5 -9.4 35.3 11.8 68.0  GLU-223   GLU-224  7.1 8.6 -45.7 -148.6 96.8 107.7 -173.4  GLU-224   ILE-225  8.7 7.3 -165.6 -7.6 65.9 70.5 215.9 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
