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-74   LYS-75  4.9 6.4 -43.7 6.9 98.8 105.0 -2.2  LYS-75   MET-76  2.9 4.2 24.7 82.6 15.1 35.7 81.4  MET-76   LYS-77  2.3 1.6 -166.3 4.1 114.1 150.9 -101.5 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
