Comparing the in vivo function of α-carboxysomes and β-carboxysomes in two model cyanobacteria

Whitehead, Lynne; Long, Benedict; Price, Graeme (Dean); Badger, Murray


The carbon dioxide (CO2)-concentrating mechanism of cyanobacteria is characterized by the occurrence of Rubisco-containing microcompartments called carboxysomes within cells. The encapsulation of Rubisco allows for high-CO2 concentrations at the site of fixation, providing an advantage in low-CO2 environments. Cyanobacteria with Form-IA Rubisco contain α-carboxysomes, and cyanobacteria with Form-IB Rubisco contain β-carboxysomes. The two carboxysome types have arisen through convergent...[Show more]
