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

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.

V01 · calculated observed ligand environment

Deposited instance PDB:6XCG:LIG:I:V01:401:.. Closest calculated PWWP-region atom distance: 2.794 Å. Five-Å native core contacts: 12; broader-Pfam contacts: 2; source-coordinate model 1.

Limitations: partial occupancy contact atoms; representative alt conformers selected

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.
