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  ALA-74   ARG-75  2.0 2.3 29.0 -2.6 137.7 138.2 -13.2  ARG-75   LYS-76  4.5 3.6 168.8 14.7 145.1 139.8 95.0  LYS-76   MET-77  4.2 2.1 86.8 37.8 120.1 119.7 -27.8 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
