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  10.3 10.3 2.9 -43.1 104.6 95.4 16.0  ARG-238   THR-239  8.2 7.2 7.5 -23.4 102.0 141.3 8.3  THR-239   ARG-240  4.5 4.4 -9.8 -21.2 11.6 38.3 25.0  ARG-240   VAL-241  3.3 4.7 -23.0 159.1 68.5 43.1 -76.8  VAL-241   ARG-242  1.5 2.7 -59.0 -83.8 32.9 21.2 100.9  ARG-242   LYS-243  1.4 3.0 -21.1 17.6 33.3 50.2 5.0  LYS-243   SER-244  0.5 1.3 -0.6 -6.1 35.6 34.7 7.1 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
