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  36.0 35.9 6.3 2.4 62.7 59.8 203.8  LYS-243   SER-244  34.1 34.3 2.4 8.7 67.5 71.8 46.5  SER-244   ILE-245  30.7 30.8 11.9 -12.9 94.3 91.1 78.0 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
