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  ASN-230   ALA-231  5.5 5.5 -3.1 -9.9 29.2 21.9 47.8  ALA-231   TYR-232  7.7 7.3 15.4 -37.7 137.5 134.2 62.6  TYR-232   LEU-233  4.6 4.2 85.8 -81.7 93.1 84.2 -31.4 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
