csoS2
Introduction
CsoS2 is an essential protein involved in the assembly and formation of α-carboxysomes, which are bacterial microcompartments designed to encapsulate enzymes such as ribulose-1,5-bisphosphate carboxylase-oxygenase (Rubisco) for carbon fixation. The carboxysome shell, composed of various proteins, serves as a selectively permeable barrier, facilitating the flux of specific metabolites while protecting enzymes from external inhibitors like oxygen. CsoS2 plays a crucial role in mediating the self-assembly of the shell and is functionally analogous to linking proteins found in β-carboxysomes, like CcmM. In the chemoautotrophic bacterium Halothiobacillus neapolitanus, CsoS2 is present in two isoforms (CsoS2A and CsoS2B), which together drive the formation of ordered, virus-like protein shells in E. coli.
