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  LYS-76   MET-77  7.3 7.0 2.3 5.8 125.1 117.1 -1.4  MET-77   LYS-78  7.1 5.9 24.9 -48.7 78.6 77.8 -3.8  LYS-78   ASP-79  4.5 2.5 55.3 9.3 117.7 105.8 -11.9  ASP-79   THR-80  1.9 3.1 -176.5 1.6 7.0 60.4 99.2  THR-80   ASP-81  3.3 3.4 12.7 -35.1 105.9 169.9 7.2  ASP-81   SER-82  4.2 3.5 72.9 -1.1 82.4 100.6 16.8  SER-82   GLU-83  3.1 2.7 8.0 -5.0 140.2 152.3 0.4 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
