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  ARG-242   LYS-243  33.2 32.8 -0.4 7.4 123.1 127.4 133.6  LYS-243   SER-244  31.1 31.0 -1.7 17.1 121.1 114.3 71.2  SER-244   ILE-245  28.0 27.8 8.9 -2.8 100.3 96.0 14.8 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
