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 10.1 -13.7 -14.6 79.0 86.1 11.7  ARG-238   THR-239  7.3 6.9 6.6 -11.2 116.5 143.8 3.5  THR-239   ARG-240  3.7 4.4 3.5 -46.5 168.3 138.6 33.4  ARG-240   VAL-241  3.5 4.4 -51.1 171.2 75.1 40.4 -79.4  VAL-241   ARG-242  0.9 2.0 -76.9 -77.5 29.1 22.7 116.9  ARG-242   LYS-243  1.8 2.7 -18.5 29.7 40.7 49.1 -5.2  LYS-243   SER-244  0.2 0.8 -8.1 7.7 32.3 33.5 1.9 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
