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-121   TYR-122  9.8 9.2 0.4 6.4 58.1 56.0 53.2  TYR-122   ALA-123  7.5 7.0 0.6 0.5 99.9 99.0 -11.5  ALA-123   TYR-124  6.1 5.7 -9.4 2.3 29.1 30.2 36.7 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
