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  GLY-49   ALA-50  21.0 23.2 137.0 0.9 94.1 63.4 -289.8  THR-54   THR-55  16.8 16.1 56.2 -136.7 157.1 141.5 403.1  THR-55   ALA-56  16.2 16.2 -40.4 92.7 80.7 62.6 -127.1  ALA-56   LYS-57  12.9 13.0 42.7 -40.8 170.0 168.9 -9.3  LYS-57   ASP-58  11.9 11.7 -11.7 5.1 74.2 64.5 -27.4 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
