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  HIS-77   TYR-78  2.2 2.0 -4.3 -9.0 38.1 36.4 136.0  TYR-78   SER-79  2.7 2.4 -4.9 -1.5 56.3 51.7 -6.1  SER-79   GLU-80  2.9 2.7 -0.6 1.0 30.1 28.5 -47.1 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
