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  6.7 5.7 4.0 20.7 71.8 65.4 5.0  MET-76   LYS-77  3.4 2.4 -53.3 4.5 86.1 104.3 -11.9  ASP-80   SER-81  5.6 7.5 -75.9 8.8 136.5 145.0 -74.1  SER-81   GLU-82  5.6 4.4 52.2 -114.3 101.8 74.9 15.4  GLU-82   GLU-83  6.0 5.5 41.3 -11.2 66.8 61.4 9.4 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
