Fig 3. Growth over time of known microcompartment-related structures.

There are currently 163 microcompartment and encapsulin-related protein structures deposited in the PDB. Structures were identified by using “microcompartment,” “carboxysome” and “encapsulin” as search terms in the PDB. The amino acid sequence of a few representative BMCs and BMVs were also used to ensure we identified all microcompartment shell proteins that have been deposited in the PDB.
