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  THR-116   THR-117  9.2 9.5 17.7 -13.4 43.3 47.3 21.2  THR-117   ALA-118  7.0 6.9 -21.2 30.4 85.6 85.4 -11.0  ALA-118   PRO-119  3.5 3.3 9.0 -13.7 83.8 101.3 97.7 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
