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  GLU-177   THR-178  7.7 7.8 19.3 -7.4 46.6 43.4 189.7  THR-178   LEU-179  5.2 5.3 -20.7 21.4 70.7 66.7 0.8  LEU-179   GLN-180  2.2 2.2 11.3 -16.0 140.6 143.6 93.2 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
