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  34.1 33.6 -6.2 10.8 121.8 122.7 123.2  LYS-243   SER-244  32.3 32.3 10.1 -1.1 59.5 63.5 6.8  SER-244   ILE-245  28.9 28.9 -0.2 1.8 85.6 89.1 43.0 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
