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-242   LYS-243  23.1 23.4 -9.1 -10.8 64.4 61.8 191.6  LYS-243   SER-244  21.7 21.5 5.2 -8.9 105.4 109.5 6.9  SER-244   ILE-245  18.1 17.9 -1.9 -6.1 87.7 90.1 -14.7 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
