Carboxysomes are closed polyhedral cellular microcompartments that increase the efficiency of carbon fixation in autotrophic bacteria. Carboxysome shells consist of small proteins that form hexameric units with semipermeable central pores containing binding sites for anions. This feature is thought to selectively allow access to RuBisCO enzymes inside the carboxysome by HCO<sub>3</sub><sup>-</sup> (the dominant form of CO<sub>2</sub> in the aqueous solution at pH 7.4) but not O<sub>2</sub>, whic ...[more]
