Function | One of the shell proteins of the carboxysome, a polyhedral inclusion where RuBisCO (ribulose bisphosphate carboxylase, rbcL-rbcS) is sequestered. Assembles into hexamers which make sheets that form the facets of the polyhedral carboxysome. The hexamer central pore probably regulates metabolite flux. |
Subunit | Homohexamer. Interacts with CcmN and CcmO in the carboxysome. |
Subcellular location | Carboxysome. |
Domain | The tight homohexamer forms a small pore which is positively charged. |
Similarity | Belongs to the bacterial microcompartments protein family. CcmK subfamily. |
