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  GLY-86   PRO-87  1.3 1.5 23.5 -13.0 81.2 93.9 -10.2  PRO-87   GLU-88  2.8 3.5 -87.4 42.5 45.3 50.9 116.2  GLU-88   ILE-89  5.7 5.9 6.2 -6.4 87.6 72.8 -33.3 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
