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-106   GLY-107  1.6 1.5 -4.4 -7.9 113.6 114.1 -84.2  GLY-107   GLN-108  2.5 2.4 10.6 0.9 51.9 63.8 119.0  GLN-108   PRO-109  3.6 3.9 -7.7 1.5 107.7 107.1 38.8  PRO-109   LYS-110  4.8 5.2 -2.8 -1.1 43.7 44.9 66.3  LYS-110   ALA-111  7.3 7.3 -1.5 -0.5 102.8 97.2 -52.3 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
