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  9.7 7.4 23.5 77.7 78.1 46.0 47.6  MET-76   LYS-77  7.3 6.0 -177.8 8.4 120.6 80.6 -33.2  SER-81   GLU-82  4.1 4.2 -118.5 61.9 52.9 66.4 37.3  GLU-82   GLU-83  7.6 7.2 -41.4 26.5 128.5 133.6 -3.6 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
