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-74   LYS-75  2.6 3.5 -14.9 -5.7 75.8 68.3 0.9  LYS-75   MET-76  3.6 4.4 25.8 63.8 153.3 134.0 -39.1  SER-81   GLU-82  9.8 10.9 81.9 90.1 98.6 77.8 -49.0 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
