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  10.2 10.2 -19.0 -25.4 70.2 85.1 18.3  ARG-238   THR-239  7.9 6.9 2.2 -12.9 106.2 142.8 5.4  THR-239   ARG-240  4.2 4.4 -5.4 -35.5 8.7 39.9 34.6  ARG-240   VAL-241  3.6 4.4 -37.5 172.8 69.2 41.5 -84.6  VAL-241   ARG-242  1.0 2.1 -78.6 -62.1 32.8 22.2 106.1  ARG-242   LYS-243  1.8 2.8 -17.0 23.2 37.6 49.3 -0.4  LYS-243   SER-244  0.2 0.6 -5.6 1.9 35.2 34.3 5.0 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
