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-75   LEU-76  7.2 7.5 -14.2 2.7 59.6 50.9 23.4  LEU-76   ARG-77  7.3 7.6 -11.8 0.2 37.5 32.1 88.7  ARG-77   GLU-78  8.4 8.0 14.0 -21.2 71.6 80.0 -36.6 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
