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  THR-329   LEU-330  12.7 12.7 -17.1 25.5 49.0 47.6 -46.4  LEU-330   ALA-331  10.9 11.2 17.8 -1.9 58.9 62.9 67.4  ALA-331   PRO-332  9.9 10.1 -11.0 -6.2 73.6 83.5 19.9  PRO-332   ASN-333  6.2 6.4 -83.1 22.4 22.0 37.2 374.9 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
