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  5.0 6.4 25.2 71.0 61.6 51.5 44.8  MET-76   LYS-77  2.8 5.7 -169.3 4.3 111.6 79.5 21.2  SER-81   GLU-82  8.9 7.6 -109.4 59.2 44.2 55.1 26.3 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
