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  ILE-237   ARG-238  25.3 25.2 -9.3 41.8 15.2 14.7 -195.9  ARG-238   THR-239  24.9 24.9 23.0 -7.2 119.0 122.5 -128.9  THR-239   ARG-240  22.8 24.1 -12.5 7.5 61.9 69.6 43.3  ARG-240   VAL-241  20.2 20.5 -12.3 -26.6 6.5 15.1 221.5  VAL-241   ARG-242  19.9 19.9 10.5 -9.9 99.3 101.2 -31.7  ARG-242   LYS-243  16.4 16.7 -14.0 0.6 58.6 46.0 115.2  LYS-243   SER-244  14.9 14.8 -11.3 -3.7 54.9 48.8 43.4  SER-244   ILE-245  11.7 11.7 -18.4 22.6 87.6 100.6 13.3 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
