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  6.7 6.7 -3.5 -100.2 103.6 88.9 -9.2  LYS-75   MET-76  5.4 3.7 148.7 -38.0 119.0 134.7 -59.9  MET-76   LYS-77  3.0 4.5 158.9 4.5 143.5 152.1 97.0  SER-81   GLU-82  6.8 6.7 -88.0 81.0 102.8 88.4 0.2  GLU-82   GLU-83  10.4 9.3 -52.7 27.5 37.3 52.0 8.0 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
