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-229   SER-230  3.0 2.6 -6.1 -0.2 160.9 165.5 -91.5  SER-230   PRO-231  3.2 3.1 13.9 7.9 57.8 61.1 186.3  PRO-231   PHE-232  0.7 0.8 -2.7 6.7 148.9 143.4 -0.7 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
