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-121   ILE-122  7.0 7.0 -7.6 12.3 104.1 106.6 57.9  ILE-122   HIS-123  4.5 4.5 -8.1 8.1 152.8 145.4 -17.0  HIS-123   PRO-124  6.1 6.3 3.2 11.9 78.6 77.5 20.1 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
