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  MET-76   LYS-77  5.8 5.4 -5.0 -31.8 92.7 96.8 -6.3  LYS-77   ASP-78  2.8 3.1 135.5 -101.3 133.4 98.6 -8.1  ASP-78   THR-79  1.2 0.2 -145.6 -29.9 19.3 22.0 112.4  THR-79   ASP-80  2.5 1.9 -7.5 24.5 81.4 46.9 -3.0  ASP-80   SER-81  3.8 3.1 12.5 12.4 97.7 111.2 2.3 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
