Gene name	Name=ccmL;

Comments [?]

FUNCTION	Probably forms vertices in the carboxysome, a polyhedral inclusion where RuBisCO (ribulose bisphosphate carboxylase, rbcL-rbcS) is sequestered. Has been modeled to induce curvature upon insertion into an otherwise flat hexagonal molecular layer of CcmK subunits.
SUBUNIT	Homopentamer. Interacts with full-length CcmM.
SUBCELLULAR LOCATION	Carboxysome.
DOMAIN	The tight homopentamer forms a pore with an opening of 4-5 Angstroms in diameter which opens into a wider tunnel at the base of the truncated pyramid. The pore is positively charged.
SIMILARITY	Belongs to the CcmL/EutN family. CcmL subfamily.
