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  10.3 10.4 -18.9 -27.1 71.7 84.7 18.3  ARG-238   THR-239  7.8 7.3 9.5 -22.9 101.4 141.7 8.8  THR-239   ARG-240  4.0 4.6 -4.1 -34.4 11.0 38.7 30.5  ARG-240   VAL-241  3.1 4.8 -51.1 -168.1 70.9 42.7 -83.8  VAL-241   ARG-242  0.6 2.5 -73.1 -65.0 29.9 21.5 100.6  ARG-242   LYS-243  1.9 3.1 -28.7 27.2 38.2 49.9 5.3  LYS-243   SER-244  0.3 1.0 -4.2 -3.7 34.7 34.6 6.4 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
