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  27.4 27.7 -9.6 -37.9 149.5 137.5 -150.1  ARG-238   THR-239  26.0 26.5 3.5 9.1 98.3 79.1 -4.2  THR-239   ARG-240  24.7 23.7 -2.3 -2.0 105.5 131.7 -23.8  ARG-240   VAL-241  20.9 21.2 4.7 32.0 48.3 31.2 105.5  VAL-241   ARG-242  19.5 20.1 -5.6 -27.2 87.9 91.1 13.9  ARG-242   LYS-243  16.4 16.3 12.0 24.9 30.8 27.0 134.5  LYS-243   SER-244  13.7 14.3 1.4 2.1 78.8 79.4 -3.2  SER-244   ILE-245  11.0 11.4 -10.1 10.3 50.1 53.9 8.4  ILE-245   GLY-246  11.6 11.8 12.0 -6.8 85.1 84.5 -26.4 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
