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  GLN-508   CYS-509  5.9 5.6 12.6 -17.6 124.5 123.8 10.4  CYS-509   SER-510  2.9 2.6 -10.3 7.6 25.2 28.8 28.9  SER-510   ASP-511  2.2 1.8 -12.3 8.7 74.9 80.1 -25.3 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
