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  LEU-632   LEU-633  10.8 10.7 5.4 -3.0 75.9 77.8 -79.7  LEU-633   TYR-634  7.0 6.9 2.1 -0.8 47.7 46.5 169.1  TYR-634   SER-635  4.4 4.3 -0.6 -3.6 91.3 91.9 -27.4 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
