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  ARG-74   LYS-75  9.8 8.1 41.3 23.2 143.2 126.2 -37.3  LYS-75   MET-76  9.2 9.5 -12.6 7.8 59.4 44.9 5.2  MET-76   LYS-77  8.3 7.2 168.5 -156.6 61.2 64.8 -10.3  LYS-77   ASP-78  8.0 4.0 40.9 71.0 153.1 124.8 -55.6  ASP-78   THR-79  6.0 3.9 102.6 -131.6 74.3 155.2 4.4  THR-79   ASP-80  4.2 5.9 158.1 -132.1 97.0 127.4 -28.5  ASP-80   SER-81  1.6 3.5 -81.9 -160.0 32.1 63.9 165.0 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
