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  26.0 26.6 4.5 -28.4 128.7 129.8 141.6  LYS-243   SER-244  24.8 24.7 0.6 -11.7 120.6 117.7 70.4  SER-244   ILE-245  21.4 21.3 -10.8 0.2 95.6 100.4 -44.8 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
