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

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
