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  ALA-121   LYS-122  3.2 4.6 -0.2 -21.7 65.6 60.1 18.5  LYS-122   THR-123  1.7 2.8 -8.1 45.0 134.5 122.0 49.0  THR-123   THR-124  3.8 3.9 2.1 -24.4 98.1 93.8 -11.8 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
