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-506   SER-507  10.4 10.5 -0.3 2.7 79.9 78.2 -18.3  SER-507   GLN-508  6.7 6.8 1.0 -3.2 59.0 58.2 -9.7  GLN-508   CYS-509  4.7 4.7 0.0 4.9 115.4 114.6 55.2  CYS-509   SER-510  1.7 1.7 -6.3 16.9 143.7 140.4 69.7  SER-510   ASP-511  3.3 3.2 -3.4 4.3 100.9 100.1 -9.4 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
