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-32   GLU-33  2.1 2.6 36.2 -18.4 74.0 72.0 4.5  GLU-33   VAL-34  2.2 2.2 41.6 24.7 5.4 5.9 77.0  VAL-34   LYS-35  2.1 2.3 9.0 -16.4 71.4 62.7 5.9 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
