CC -!- FUNCTION: Probably forms vertices in the carboxysome, a polyhedral
CC inclusion where RuBisCO (ribulose bisphosphate carboxylase, rbcL-rbcS)
CC is sequestered. Has been modeled to induce curvature upon insertion
CC into an otherwise flat hexagonal molecular layer of CcmK subunits.
CC {ECO:0000250|UniProtKB:P72759, ECO:0000255|HAMAP-Rule:MF_00858}.
CC -!- SUBUNIT: Homopentamer (PubMed:23949415, PubMed:24504539). May interact
CC with CcmK2, this occurs at very high CcmK2 concentrations (Probable).
CC Interacts with full-length CcmM (By similarity).
CC {ECO:0000250|UniProtKB:P72759, ECO:0000269|PubMed:23949415,
CC ECO:0000269|PubMed:24504539, ECO:0000305|PubMed:24504539}.
CC -!- SUBCELLULAR LOCATION: Carboxysome {ECO:0000250|UniProtKB:Q03512,
CC ECO:0000255|HAMAP-Rule:MF_00858}. Note=This cyanobacterium makes beta-
CC type carboxysomes (Probable). Probably forms vertices in the
CC carboxysome (Probable). {ECO:0000305|PubMed:23949415}.
CC -!- DOMAIN: The tight homopentamer forms a pore with an opening of 4-5
CC Angstroms in diameter which opens into a wider tunnel at the base of
CC the truncated pyramid. The pore is positively charged.
CC {ECO:0000255|HAMAP-Rule:MF_00858, ECO:0000269|PubMed:23949415,
CC ECO:0000269|PubMed:24504539}.
CC -!- SIMILARITY: Belongs to the CcmL/EutN family. CcmL subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00858}.
