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  GLU-235   PRO-236  17.0 16.0 -16.2 20.6 138.2 131.2 0.6  PRO-236   ILE-237  14.4 13.3 -5.6 -28.9 84.4 85.9 4.9  ILE-237   ARG-238  11.0 10.2 -19.8 -27.3 67.3 84.4 19.5  ARG-238   THR-239  8.7 7.2 14.6 -17.7 96.8 141.2 1.2  THR-239   ARG-240  5.1 4.3 -2.3 -32.7 12.2 38.1 28.2  ARG-240   VAL-241  3.9 4.7 -50.7 -172.3 72.2 43.2 -81.0  VAL-241   ARG-242  1.2 2.8 -78.9 -67.1 36.1 21.3 102.9  ARG-242   LYS-243  1.8 3.0 -18.2 10.3 35.2 50.1 12.0  LYS-243   SER-244  1.1 1.6 13.2 -2.9 141.1 145.1 -5.3 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
