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-60   LEU-61  0.9 0.4 -10.4 2.3 109.5 114.0 -46.6  LEU-61   LEU-62  2.5 3.0 7.4 -2.4 26.1 29.2 46.2  LEU-62   ARG-63  1.0 1.3 10.7 -10.1 93.5 99.6 4.3 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
