Comments As much as 80 % of the ribulose-1,5-bisphosphate carboxylase- oxygenase (RubisCO 3-phospho-D-glycerate carboxylase [dimerizing], EC 4.1.1.39) activity of Thiobacillus neapolitanus can be found within polyhedral inclusion bodies called carboxysomes (Shively et al., 1973 PMID 4355679 Beudeker et al., 1980 Arch Microbiol 124: 185-189).
