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  4.4 4.6 19.3 -21.8 103.7 107.4 19.6  ILE-229   SER-230  2.7 3.5 2.9 2.6 139.7 137.9 -20.6  SER-230   PRO-231  5.7 6.6 -16.9 -12.9 61.8 53.3 96.8 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
