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-1237   ARG-1238  10.3 10.5 -24.9 -18.9 66.4 85.5 14.6  ARG-1238   THR-1239  8.1 7.4 11.3 -17.4 101.5 141.1 1.2  THR-1239   ARG-1240  4.5 4.6 20.6 -53.6 167.6 141.2 26.8  ARG-1240   VAL-1241  3.9 4.8 -27.2 162.9 74.3 43.2 -80.7  VAL-1241   ARG-1242  1.1 2.6 -78.0 -70.5 37.3 20.7 108.1  ARG-1242   LYS-1243  1.9 3.0 -21.3 30.0 35.9 50.8 3.8  LYS-1243   SER-1244  0.5 1.2 0.0 4.3 33.8 33.9 -1.3 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
