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-69   THR-70  2.1 2.5 -20.7 11.2 36.7 33.1 6.8  THR-70   MET-71  3.2 3.8 -4.5 6.6 66.0 53.1 2.5  MET-71   MET-72  2.7 2.3 9.8 -11.5 117.1 126.3 1.7  MET-72   ALA-73  2.1 1.4 41.9 38.0 150.9 145.8 -40.3  SER-81   GLU-82  9.8 10.5 88.1 65.4 101.1 90.2 -55.3 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
