`assembly`

Pack: rcsb-pdb · Endpoint: https://gateway.pipeworx.io/rcsb-pdb/mcp

“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.
