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-241   SER-242  9.1 9.1 8.3 -5.6 69.7 71.1 16.3  SER-242   ILE-243  8.8 8.8 4.4 2.6 19.0 18.0 196.4  ILE-243   ASP-244  9.8 9.8 4.3 -2.4 80.2 81.0 -231.5 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
