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.
