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  SER-75   TYR-76  4.8 5.2 145.8 11.3 33.4 43.0 181.7  TYR-76   VAL-77  4.2 3.9 -28.1 10.6 98.8 77.2 15.7  VAL-77   PHE-78  3.6 3.6 -3.0 -6.1 46.4 46.8 10.8 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
