Determination of protein backbone structures from residual dipolar couplings.
In a cross-b motif, the hydrogen bonding capacity of the polypeptide backbone can be fully utilized.
No changes are found in the backbone conformation of the -helical bundle itself, indicating rather stable and rigid structure of the four -helical coiled coil.
In this structure, half of the backbone hydrogen bonds are intramolecular.
Quantitative constraints on backbone w and y torsion angles can be obtained from tensor correlation measurements, as discussed above.
In view of its systematic character, the public law system provides a rigid backbone which restricts opportunities for swift and single-handed institutional reorganisation.
Low cost multi-port devices, called hubs are easily connected to the network backbone, the task of adding devices to the network thus becoming easier.
Aristocratic patronage was the backbone of the event.
