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  ARG-91   THR-92  4.0 2.2 -8.1 39.7 62.3 81.7 -7.4  THR-92   TRP-93  2.0 1.8 -40.4 -42.1 39.0 21.6 46.1  TRP-93   ALA-94  0.7 2.5 -150.4 84.2 35.2 36.8 36.6  ALA-94   PRO-95  1.3 0.8 -26.8 -5.8 52.7 60.5 11.9 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
