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-100   SER-101  7.0 5.1 54.1 -1.1 125.9 81.4 -11.6  SER-101   ALA-102  5.7 4.4 -59.6 8.6 48.5 45.4 38.2  ALA-102   ALA-103  3.9 7.9 -2.2 -0.1 118.3 59.2 1.0  ALA-103   GLU-104  3.2 7.9 -1.4 1.8 112.1 42.3 -0.9 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
