Bacterial microcompartments (BMCs) are self-assembling organelles that consist of an
enzymatic core that is encapsulated by a selectively permeable protein shell. The potential …

Cyanobacteria are the globally dominant photoautotrophic lineage. Their success is
dependent on a set of adaptations collectively termed the CO2-concentrating mechanism …

Summary Approximately 30%–40% of global CO 2 fixation occurs inside a non-membrane-
bound organelle called the pyrenoid, which is found within the chloroplasts of most …

In photosynthetic organisms, d-ribulose-1, 5-bisphosphate carboxylase/oxygenase
(Rubisco) is the major enzyme assimilating atmospheric CO2 into the biosphere. Owing to …

Cells use compartmentalization of enzymes as a strategy to regulate metabolic pathways
and increase their efficiency. The α-and β-carboxysomes of cyanobacteria contain ribulose …

Chloroplast function is orchestrated by the organelle's intricate architecture. By combining
cryo-focused ion beam milling of vitreous Chlamydomonas cells with cryo-electron …

Carboxysomes are bacterial microcompartments that function as the centerpiece of the
bacterial CO2-concentrating mechanism by facilitating high CO2 concentrations near the …

Carboxysomes are a family of bacterial microcompartments (BMCs), present in all
cyanobacteria and some proteobacteria, which encapsulate the primary CO 2-fixing …

Highlights•Alpha and beta carboxysomes differ in composition, assembly, and
evolution.•Alphas appear to co-assemble shell and cargo proteins; betas assemble inside …

The carboxysome is a protein-based organelle for carbon fixation in cyanobacteria,
keystone organisms in the global carbon cycle. It is composed of thousands of subunits …
