Bacterial microcompartments are primitive organelles composed entirely of protein subunits. Genomic sequence databases reveal the widespread occurrence of microcompartments across diverse microbes. The prototypical bacterial microcompartment is the carboxysome, a protein shell for sequestering carbon fixation reactions. We report three-dimensional crystal structures of multiple carboxysome shell proteins, revealing a hexameric unit as the basic microcompartment building block and showing how… 
The Shells of BMC-Type Microcompartment Organelles in Bacteria
TLDR
This review updates the understanding of bacterial microcompartment shells, how they are assembled, and how they carry out their functions in molecular transport and enzyme organization.
Bacterial microcompartment organelles: protein shell structure and evolution.
TLDR
Current structural, evolutionary, and mechanistic ideas are discussed, along with genomic studies for exploring the function and diversity of this family of bacterial organelles.
Structural characterization of hexameric shell proteins from two types of choline-utilization bacterial microcompartments.
TLDR
Six structures of hexameric shell proteins from type I and type II choline-utilization microcompartments are reported, revealing electrostatic surface properties that are shared between the four types of shell proteins described here.
Atomic-Level Models of the Bacterial Carboxysome Shell
TLDR
Two proteins of previously unknown function assemble to form pentameric structures whose size and shape are compatible with formation of vertices in an icosahedral shell, and combining these pentamers with the hexamers previously elucidated gives two plausible, preliminary atomic models for the carboxysome shell.
Protein-based organelles in bacteria: carboxysomes and related microcompartments
TLDR
The carboxysome, a prototypical bacterial microcompartment that is found in cyanobacteria and some chemoautotrophs, encapsulates ribulose-1,5-bisphosphate carboxylase/oxygenase and carbonic anhydrase, and thereby enhances carbon fixation by elevating the levels of CO2 in the vicinity of RuBisCO.
Assembly principles and structure of a 6.5-MDa bacterial microcompartment shell
TLDR
The crystal structure of an intact shell from Haliangium ochraceum is presented, revealing the basic principles of bacterial microcompartment shell construction and can inform the design and engineering of shells with new functionalities.

TLDR
This review evaluates the evidence that relates carboxysome structure to function in the carbon metabolism of autotrophic prokaryotes and examines similarities to newly discovered particles found in heterotrophs.
A HEX-1 crystal lattice required for Woronin body function in Neurospora crassa
TLDR
The crystal structure of HEX-1 is solved at 1.8 Å, which provides the structural basis of its self-assembly and reveals the existence of three intermolecular interfaces that promote the formation of a three-dimensional protein lattice.

TLDR
It is reported that the carboxysomal shell protein, CsoS3, from Halothiobacillus neapolitanus is a novel carbonic anhydrase (epsilon-class CA) that has an evolutionary lineage distinct from those previously recognized in animals, plants, and other prokaryotes.
Translocation portals for the substrates and products of a viral transcription complex: the bluetongue virus core
TLDR
To determine how the logistical problems of transcription within a sealed shell are solved, core crystals were soaked with various ligands and analysed by X‐ray crystallography, demonstrating that nucleotides also bind to the outer core layer, providing a substrate sink.
