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  GLY-78   VAL-79  2.5 3.7 10.5 -13.7 77.3 86.9 -3.5  VAL-79   LYS-80  2.1 2.5 4.6 24.2 112.5 109.2 -36.3  LYS-80   LYS-81  2.9 1.9 -17.6 -34.9 0.5 19.1 156.6 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
