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  6.8 7.2 -17.0 -77.6 103.4 88.8 -7.7  LYS-75   MET-76  5.5 3.8 90.9 4.3 119.2 139.2 -52.5  MET-76   LYS-77  3.1 4.6 -135.5 -30.3 36.7 25.9 80.4  SER-81   GLU-82  6.9 7.2 -105.2 85.0 102.9 81.6 -1.6  GLU-82   GLU-83  10.5 9.3 -44.9 20.5 37.5 47.4 7.7 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
