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  28.6 29.0 -3.2 -15.1 47.8 46.2 180.9  LYS-243   SER-244  26.7 26.5 2.7 -10.9 99.9 101.9 80.8  SER-244   ILE-245  23.3 23.2 -7.3 5.5 106.2 110.5 10.2 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
