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-537   PRO-538  4.7 5.0 26.4 -25.3 32.0 34.4 2.1  PRO-538   LEU-539  7.3 7.3 6.1 27.1 37.6 45.7 54.6  LEU-539   THR-540  5.6 5.3 36.4 -19.9 53.0 72.3 50.1 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
