Model-aware structural assessment
Counts concern the annotated PWWP core. Different NMR models are evaluated independently, without averaging their coordinates into an artificial model.
| Model | Core residues observed | Missing backbone | Missing side-chain (union) | Missing side-chain (consistent conformer) | Partial occupancy residues | Unassessable chemistry |
|---|---|---|---|---|---|---|
| 1 | 61 | 0 | 0 | 0 | 7 | 0 |
Experimental ligand environments
Only separately source-classified research ligands are listed. Native annotation-core contacts and broader Pfam-fold contacts are identified separately. A simple distance is not an experimental affinity or density-quality score.
No verified research-ligand local environment is assigned to this chain/domain. It may be apo, structurally incomplete, or lack the necessary source-role verification.
Residue-level coordinate and atom completeness
"Missing" applies only to residues with observed atoms and supported chemical templates. Unobserved residues are reported separately. Alternate-conformer union presence is distinct from a single internally consistent conformer.
