How this service works
Give the experimental structures or the predicted model of a protein by its UniProt accession.
Output
Returns a list of protein structure records for the given UniProt accession. For experimental coverage, results include PDB entries sorted by newest release, up to the requested limit (1–25). For predicted coverage, returns the predicted structural model data. Each entry includes relevant structure identifiers and metadata.
Example use cases
Retrieve predicted model for drug target
“I'm researching a potential drug target — can you get the predicted 3D model for the protein with UniProt accession Q9Y253?”
Find latest crystal structures for cancer protein
“Look up the 10 newest experimental PDB structures for the tumor suppressor protein P04637 so I can compare their conformations.”
Check structural coverage for unknown protein
“For UniProt accession O00206, can you check whether there are any experimental structures available and return up to 25 of them?”
Technical details
Endpoint
POSThttps://win.oneshotagent.com/v1/tools/lookup/protein-structure?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need protein 3D structure data keyed by a UniProt accession and want to choose between experimental (PDB) or predicted (e.g. AlphaFold) structures. Prefer this over general bioinformatics search APIs when you already have the UniProt ID and need structured, per-protein results with control over how many entries to retrieve.
Side effects
- Invalid or malformed UniProt accession returns an error
- Protein with no experimental structures returns an empty list
- Predicted model unavailable for obscure or uncharacterized proteins
- Limit parameter out of range (must be 1–25) returns validation error
- Network or upstream database timeout causes failure
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| limit | integer | How many experimental structures to return, newest release first (1 to 25). Ignored for predicted. From 1 to 25. Defaults to `10`. |
| coverage | string | Which kind of structure: experimental (entries in the Protein Data Bank) or predicted (the predicted model) |
| accession | string | The UniProt accession of the protein, for example P04637. A UniProt accession is 6 or 10 letters and digits in the UniProt form. |
