Comments "Carboxysomes are very large and sophisticated multi-protein complexes. They are about 80–150 nm in cross section and are bounded by a 3–4 nm thick protein shell (Fig. 1). Their mass is about 300 MDa and they are composed of several thousand polypeptides of 10–15 different types.(primary sources)"
