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  10.1 10.2 3.1 -44.4 103.9 94.6 15.9  ARG-238   THR-239  8.0 7.0 -12.4 2.9 76.7 38.0 2.8  THR-239   ARG-240  4.3 4.3 -7.2 -34.3 9.3 39.5 34.1  ARG-240   VAL-241  3.5 4.5 -33.1 170.7 74.9 42.3 -82.6  VAL-241   ARG-242  0.9 2.3 -66.7 -77.2 32.6 21.5 104.8  ARG-242   LYS-243  1.9 2.8 -24.5 26.5 39.4 50.0 2.3  LYS-243   SER-244  0.3 1.0 -12.9 9.3 31.1 34.0 3.9 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
