Abstract

α-carboxysomes are large, heterogeneous bodies that fix CO₂ in cyanobacteria. In this issue of Structure, Evans et al. (2023) report a cryo-electron microscopy study of the α-carboxysome from Cyanobium sp. PCC 7001 along with modeling of its icosahedral shell and the packing of RuBisCO within its interior.
