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  ASP-1139   TYR-1140  2.1 2.3 3.0 -4.8 26.7 26.3 -33.3  TYR-1140   VAL-1141  1.1 0.8 -8.8 0.9 86.7 88.8 9.2  VAL-1141   SER-1142  3.4 3.2 1.0 -14.6 80.9 71.5 -78.8 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
