`assembly`

Pack: rcsb-pdb · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/assembly for the schema, then POST the same URL with its arguments for the data.

“Biological assembly of [pdb_id]” / “functional oligomer for [PDB entry]” — fetch a biological assembly record (the functional oligomeric unit, which often differs from the crystallographic asymmetric unit). Use when you need the actual functional form of a protein (dimer / tetramer / etc.) rather than the crystal contents.

Parameters

`pdb_id`	string	yes
