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  ASN-240   LYS-241  18.0 16.1 46.6 54.8 108.4 125.8 -95.6  LYS-241   SER-242  14.4 12.6 -8.3 -14.6 111.4 107.1 -31.3  SER-242   LYS-243  11.1 10.6 14.4 19.2 139.4 109.4 -43.1  LYS-243   ILE-244  9.1 6.9 138.5 -43.9 73.0 145.3 244.8  ILE-244   PRO-245  6.1 6.3 -141.7 -71.7 79.0 77.8 6.0  PRO-245   HIS-246  3.3 3.3 -7.4 -10.9 140.8 141.2 -19.5 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
