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  25.3 26.0 -4.5 -4.2 49.2 44.3 90.0  LYS-243   SER-244  23.9 24.0 5.6 -15.7 116.3 118.1 91.2  SER-244   ILE-245  20.5 20.8 -7.3 8.5 98.6 101.5 13.0 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
