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  ILE-300   ARG-301  18.5 12.4 -171.1 41.6 133.8 131.9 205.8  ARG-301   MET-302  16.7 13.0 -161.9 54.4 139.5 72.2 -34.5  MET-302   SER-303  18.3 11.5 -158.5 67.6 135.8 90.8 -30.2  SER-303   PHE-304  17.1 8.0 165.7 38.4 51.2 44.1 -181.9  PHE-304   VAL-305  18.7 7.1 -162.8 -161.2 159.3 80.2 25.1  VAL-305   LYS-306  19.2 8.9 25.4 54.8 77.2 144.6 198.8  LYS-306   GLY-307  16.9 7.6 172.4 35.0 144.9 91.0 -199.6  GLY-307   TRP-308  17.6 5.3 114.2 101.3 96.4 71.2 13.3  THR-309   VAL-310  12.0 10.6 142.8 26.9 81.7 139.7 -77.3 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
