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 10.2 -24.2 -6.8 78.5 86.2 12.1  ARG-238   THR-239  7.3 6.9 -2.6 -18.4 66.4 36.1 12.7  THR-239   ARG-240  3.6 4.4 14.8 -48.5 176.9 138.3 26.4  ARG-240   VAL-241  3.5 4.5 -47.9 -169.5 70.2 40.2 -87.0  VAL-241   ARG-242  0.7 2.1 -77.6 -83.1 21.1 22.8 124.0  ARG-242   LYS-243  1.8 2.8 -14.1 25.1 41.3 49.0 -5.1  LYS-243   SER-244  0.1 0.9 5.6 -3.0 143.4 146.7 -0.9 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
