PDBe: Experimental Structures
experimental_structuresRetrieve experimentally-solved protein structures for a plant locus using PDBe. Returns ranked PDB entries with experimental method, resolution, and coverage; indicates when no structure exists.
Instructions
Fetch experimentally-solved (X-ray / cryo-EM / NMR) protein structures for a locus from PDBe (www.ebi.ac.uk/pdbe; free, no key). Resolves the locus → UniProt accession, then returns PDBe's best_structures mapping ranked best-first: per entry the PDB id, chain, experimental method, resolution, coverage, and modelled residue span. Most plant proteins have NO deposited structure — that returns found=false (a normal outcome, not an error); a locus with no UniProt entry raises a typed NotFoundError. structure_count is the true total even when the list is capped. Complements alphafold_structure (the predicted view). Works for all 12 organisms (UniProt-keyed). Defaults to arabidopsis_thaliana; pass organism= for other species.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| locus | Yes | e.g. AT4G09760 (Arabidopsis), Os01g0100100 (rice RAP-DB) | |
| organism | No | Plant organism — accepts canonical slug (arabidopsis_thaliana), scientific or common name, or NCBI taxid | arabidopsis_thaliana |
Output Schema
