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-75   MET-76  8.9 6.9 23.7 77.6 83.2 46.2 44.7  MET-76   LYS-77  6.3 5.2 -175.5 3.3 122.7 74.3 -27.9  SER-81   GLU-82  5.1 4.4 -116.7 58.9 56.2 71.2 38.6  GLU-82   GLU-83  8.6 7.3 -35.5 17.1 131.9 133.9 -2.2 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
