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  SER-81   GLU-82  11.6 10.7 -122.0 58.1 54.5 65.3 53.4  GLU-82   GLU-83  8.7 8.0 -35.5 21.0 112.6 123.4 -6.5  GLU-83   GLU-84  7.9 7.4 -9.8 -3.6 135.9 136.4 -8.6  GLU-84   ILE-85  6.4 6.4 -7.5 13.8 60.7 72.5 11.3  ILE-85   ARG-86  4.7 4.8 4.0 -15.4 102.9 96.7 -2.1 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
