Controlled Vocabulary
| Allowed Value | Details |
|---|---|
| NOE | Distance constraints determined from NOE experiments |
| NOE build-up | Distance constraints determined from a series of NOE experiments with different mixing times |
| NOE not seen | Distance constraints supplied when an expected NOE was not observed |
| ROE | Distance constraints determined from ROE experiments |
| ROE build-up | Distance constraints determine from a series of ROE experiments with different mixing times |
| disulfide bond | Disulfide bond distance constraints |
| general distance | Specific distance constraint is not known |
| hydrogen bond | Hydrogen bond distance constraints |
| paramagnetic relaxation | Distance constraints determined from paramagnetic relaxation studies |
| symmetry | Distance constraint enforces symmetry - for example to enforce symmetry between monomers in a multimer |
