Bending Residue Dihedral Analysis

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-70   MET-71  12.5 13.1 -4.4 16.5 44.6 40.3 -7.3  MET-71   MET-72  12.0 12.6 -16.8 3.1 44.2 62.7 6.3  MET-72   ALA-73  11.9 11.7 5.1 -1.9 78.8 61.8 2.3  GLU-84   ILE-85  6.5 5.9 11.9 -8.5 109.6 106.9 -0.1  ILE-85   ARG-86  7.1 6.8 -9.1 8.8 4.6 9.2 2.2 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
