Pull experimental structures,
citation and resolution attached.
The Protein Data Bank is the archive of experimentally-determined 3D structures. pdb_search and pdb_entry return a structure with the facts that decide whether to trust it — method, resolution, and the primary citation — pinned to its PDB ID and download URLs.
What the instrument does
RCSB PDB is the worldwide repository of macromolecular structures solved by X-ray crystallography, cryo-EM and NMR. Each entry records how it was determined and at what resolution.
On the console, pdb_search finds structures and pdb_entry returns a single one — method, resolution, molecular weight, primary citation (with DOI and PMID) and direct .pdb/.cif download links.

How Perslis integrates RCSB PDB
PDB is where a protein's structure claim becomes checkable. A UniProt entry lists its cross-referenced PDB IDs; the console follows one straight to pdb_entry, and the resolution and primary citation come back with it — so a structural statement always carries the evidence and the paper behind it.
Experimental structure sits deliberately beside AlphaFold's prediction on the same bench: an agent can compare a measured structure against a predicted one and see, from the metadata, which is which.
Ask
One question at the console — no per-service query language, no tab-hopping.
Route
Lois calls this instrument alongside the others and gathers what returns.
Pin
Every field keeps its source: database, accession, URL. A result that cannot name its source is refused by construction.
Admit
The PEEL gate decides what enters the lab record. Reported values stay verbatim; unsupported claims stay out.
A real, source-pinned result
Pulled live from the service and pinned to its identifier — the same contract every answer on the console is held to.

Why route RCSB PDB through one console
Structures, callable
An agent pulls a real structure with method and resolution — no manual RCSB browsing.
Anchored to UniProt
A UniProt accession's cross-referenced PDB IDs resolve here directly — one protein, its structures.
Evidence travels with it
Every structure carries its resolution and primary citation, so trust is a fact, not a vibe.
Instruments RCSB PDB talks to
A structure is one view of a protein. PDB answers next to its UniProt anchor, its predicted model and its domains.
UniProt
Curated proteins — function, disease links, domains, sequence.
uniprot_search · uniprot_entryAlphaFold DB
Predicted structures for UniProt accessions, with confidence data.
alphafold_structureInterPro
Protein families, domains and sites — and an honest zero when nothing matches.
