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  ALA-255   ARG-256  8.9 4.7 167.2 8.6 118.0 105.6 71.2  ARG-256   THR-257  5.7 2.5 8.8 -19.9 164.0 37.1 -2.6  THR-257   ILE-258  4.5 3.9 172.6 -24.2 94.2 98.5 42.1  ILE-258   ARG-259  2.5 4.8 37.5 -16.5 38.3 41.3 14.8 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
