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-76   MET-77  2.9 5.3 -30.8 50.4 140.2 132.9 13.0  MET-77   LYS-78  3.7 4.5 -50.0 11.2 127.6 82.2 -4.9  LYS-78   ASP-79  0.9 1.0 153.3 3.7 86.8 137.4 103.3 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
