# Protplex

Natural language search across Protein Data Bank structures

Listed in ChatGPT

Overview

## What Protplex does

Protplex puts a natural language layer over the Protein Data Bank. Instead of matching on identifiers or exact field values, it works from condensed profiles of each entry describing structure, function and biochemistry.

The searchable dimensions listed are function, structure, chemistry, source organism, assembly, bound ligands and experimental context, across a collection the record puts at more than 240,000 structures. A single query can therefore combine constraints that would otherwise mean several separate searches, as in the record's own example of archaeal enzymes carrying a particular cofactor.

The record describes search and retrieval, with no mention of structure prediction, alignment or visualisation.

### Who it is for

Structural biologists and biochemists who search the PDB by description rather than accession code.

### What stands out

Distilled profiles let one query mix organism, ligand and experimental context together.

Availability

## Where Protplex is listed

Protplex is listed in the ChatGPT apps directory only. Straintest has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
