Carboxysomes are anabolic bacterial microcompartments that play an essential role in carbon fixation in cyanobacteria and some chemoautotrophs. This self-assembling organelle encapsulates the key CO2-fixing enzymes, Rubisco, and carbonic anhydrase using a polyhedral protein shell that is constructed...
The fixation of dissolved inorganic carbon (DIC) such as CO2 and bicarbonate is fundamental to the global primary production. Many autotrophs depend on a diversity of CO2-concentrating mechanisms (CCMs) to overcome the inefficiency of ribulose-1,5-bisphosphate carboxylase/oxygenase and the limited s...
