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  ILE-244   PRO-245  9.0 8.8 -4.2 18.3 142.7 142.3 83.1  PRO-245   HIS-246  8.6 8.7 3.2 -26.7 83.2 88.2 7.0  HIS-246   GLY-247  10.2 10.2 2.7 -15.6 11.4 25.3 -77.3 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
