Comprehensive structure quality

Residue and heavy-atom completeness calculated directly from 230 source PDBx/mmCIF files, each verified against its frozen historical checksum. Each mapped PWWP chain/domain, NMR model and qualified source-supported ligand environment is tracked individually.

9FOC · NSD2 PWWP1

Newly assessed ligand-bearing structure

Protein and bound ligand coordinates are deposited, but the literature's assayed compound 11 preparation remains stereochemically unresolved. Structural components do not fix that ambiguity.

2M16 · PSIP1 PWWP

Deposited NMR ensemble

All model-specific atom observations are retained. Ensemble variation is not represented by a single first-model structure alone.

Inspect model coverage

11OA · DNMT3A PWWP1

Independently confirmed side-chain gaps

Five observed-core chains each lack 198 standard side-chain heavy atoms; 13 other mapped chains contain no observed core coordinates.

Reproducible scientific exports

Individual experimental mmCIF files are verified by their original SHA-256. Core coordinates, standard heavy-atom templates and source UniProt mappings are analyzed model-by-model. Union-of-alternates and conformer-consistent completeness are distinct; 5 Å and 6 Å geometric proximity are not equivalent to a validated interaction.
