CC -!- FUNCTION: One of the shell proteins of the carboxysome, a polyhedral
CC inclusion where RuBisCO (ribulose bisphosphate carboxylase, rbcL-rbcS)
CC is sequestered. Assembles into hexamers which make sheets that form the
CC facets of the polyhedral carboxysome. The hexamer central pore probably
CC regulates metabolite flux. {ECO:0000256|HAMAP-Rule:MF_00854}.
CC -!- SUBUNIT: Homohexamer. Interacts with CcmN and CcmO in the carboxysome.
CC {ECO:0000256|HAMAP-Rule:MF_00854}.
CC -!- SUBCELLULAR LOCATION: Carboxysome {ECO:0000256|ARBA:ARBA00023587,
CC ECO:0000256|HAMAP-Rule:MF_00854}.
CC -!- DOMAIN: The tight homohexamer forms a small pore which is positively
CC charged. {ECO:0000256|HAMAP-Rule:MF_00854}.
CC -!- SIMILARITY: Belongs to the bacterial microcompartments protein family.
CC CcmK subfamily. {ECO:0000256|HAMAP-Rule:MF_00854}.
