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  28.3 29.1 -7.8 -8.2 57.2 55.2 130.6  LYS-243   SER-244  27.4 27.5 0.0 -10.8 128.4 129.6 66.0  SER-244   ILE-245  24.1 24.4 -1.4 -2.9 88.5 90.2 6.7 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
