DescriptionNMR-STAR name: _Entity.Ambiguous_conformational_states
Please indicate by answering yes or no if the molecule exists in multiple conformational states that have not been or cannot be clearly defined. In some cases, proteins have been found to exhibit multiple peaks for a single proton or carbon atom that may be caused by cis/trans isomerization at one or more proline residue. If the peaks have not been associated specifically with the isomeric state of a defined proline residue, the conformational heterogeneity of the protein has not been determined and the molecule exists in undetermined or ambiguous conformational states. Similar circumstances may exist for other kinds of biopolymers and ligands.
