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  VAL-228   ILE-229  4.3 4.4 19.2 -22.4 100.5 104.2 18.6  ILE-229   SER-230  2.7 3.5 -0.5 -0.6 41.5 41.7 -5.2  SER-230   PRO-231  5.8 6.7 -16.8 -11.1 64.8 60.8 80.0 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
