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-75   LYS-76  4.6 3.7 -1.4 41.2 139.0 113.5 -184.3  LYS-76   MET-77  4.8 5.0 -26.0 53.9 116.8 117.1 13.9  MET-77   LYS-78  2.7 3.4 -78.8 4.3 115.5 164.8 147.7  LYS-78   ASP-79  0.8 1.3 -76.1 -99.0 173.2 108.8 -76.6 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
