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  ARG-284   VAL-285  4.4 4.9 3.7 -4.7 57.3 56.2 -5.4  VAL-285   PHE-286  5.2 5.5 -2.2 8.9 88.2 88.1 5.1  PHE-286   SER-287  3.6 3.5 4.0 -36.5 149.4 153.2 126.7 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
