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  10.4 10.5 -16.6 -28.5 71.4 85.5 14.9  ARG-238   THR-239  8.0 7.3 9.6 -17.3 101.6 142.1 3.1  THR-239   ARG-240  4.2 4.7 -12.5 -35.6 7.8 39.7 40.3  ARG-240   VAL-241  3.5 4.8 -45.5 175.9 65.7 42.2 -77.8  VAL-241   ARG-242  1.3 2.4 -68.1 -69.0 38.2 21.5 98.0  ARG-242   LYS-243  1.7 3.0 -15.2 17.0 34.9 50.0 3.3  LYS-243   SER-244  0.7 0.9 4.3 -1.9 140.5 146.2 0.7 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
