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  30.5 29.9 7.1 10.8 51.5 53.7 204.7  LYS-243   SER-244  28.2 28.1 -10.9 13.5 110.9 111.5 28.0  SER-244   ILE-245  24.9 24.8 6.4 -0.7 93.8 95.9 -25.4  ILE-245   GLY-246  24.2 24.2 12.2 -48.8 83.7 73.9 -41.9 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
