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  SER-235   GLY-236  2.4 2.4 -7.5 9.1 128.7 129.5 21.8  GLY-236   ARG-237  4.6 4.2 -4.6 1.4 84.0 85.0 -25.2  ARG-237   LEU-238  7.6 7.2 -9.0 4.4 116.9 115.7 -27.6 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
