Solution NMR structures are typically represented as collections of coordinate sets, where each model in the collection is independently generated by fitting experimental data to a single conformer. This is done multiple times under different initialization conditions, generating a collection of conformers. The singlestate model representation commonly used for NMR structures encodes information about which regions of the protein structure are "well-defined" by the NMR data and which regions are not. Less-well-defined segments of the structure often (but not always) correspond to regions undergoing conformational dynamics. In the simplest case, the coordinates for the collection of conformer models are deposited to the PDB, accompanied by restraints, while the chemical shifts, peaks lists, and raw FID data are deposited to the Biological Magnetic Resonance Bank (BMRB).
