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  GLN-227   VAL-228  3.8 3.7 -8.6 3.0 121.2 122.9 -156.6  VAL-228   ILE-229  5.5 5.4 2.5 -1.1 26.5 30.7 99.8  ILE-229   SER-230  5.8 5.7 3.3 -1.6 67.7 67.0 -43.5 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
