Title: Carboxysomes: metabolic modules for CO 2 fixation

The carboxysome is a bacterial microcompartment encapsulating the enzymes carbonic anhydrase and ribulose-1,5-bisphosphate carboxylase/oxygenase. As the site of CO 2 fixation, it serves an essential role in the carbon dioxide concentrating mechanism of many chemoautotrophs and all cyanobacteria. Carboxysomes and other bacterial microcompartments self-assemble through specific protein–protein interactions that are typically mediated by conserved protein domains. In this review, we frame our current understanding of carboxysomes in the context of their component protein domains with their inherent function as the ‘building blocks’ of carboxysomes. These building blocks are organized in genetic modules (conserved chromosomal loci) that encode for carboxysomes and ancillary proteins essential for the integration of the organelle with the rest of cellular metabolism. This conceptual framework provides the foundation for ‘plug-and-play’ engineering of carboxysomes as CO 2 fixation modules in a variety of biotechnological applications.
