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  LYS-81   GLU-82  3.9 2.5 165.5 -18.2 78.7 51.0 493.4  GLU-82   TRP-83  2.8 2.3 -10.8 -7.6 153.8 144.3 -108.8  TRP-83   LYS-84  5.2 4.8 9.0 -11.4 59.2 58.9 25.8 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
