Comments
[?]
| 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. |
