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  10.5 10.5 -17.8 -18.4 75.5 85.4 17.2  ARG-238   THR-239  8.0 7.3 12.1 -26.3 107.3 142.2 8.1  THR-239   ARG-240  4.3 4.6 -5.6 -24.8 8.4 39.6 22.5  ARG-240   VAL-241  3.5 4.8 -54.6 -169.7 73.9 42.1 -75.8  VAL-241   ARG-242  0.6 2.4 -79.3 -64.3 34.0 21.6 103.9  ARG-242   LYS-243  2.2 3.0 -8.0 8.5 36.7 49.9 3.3  LYS-243   SER-244  0.4 0.9 1.1 -5.8 144.0 146.0 5.6 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
