Carbon dioxide concentrating mechanism K (CcmK)-like proteins, Bacterial Micro-Compartment (BMC) domain; Bacterial micro-compartments are primitive protein-based organelles that sequester specific metabolic pathways in bacterial cells. The prototypical bacterial microcompartment is the carboxysome shell, a bacterial polyhedral organelle which increase the efficiency of CO2 fixation by encapsulating RuBisCO and carbonic anhydrase. They can be divided into two types: alpha-type carboxysomes (alpha-cyanobacteria and proteobacteria) and beta-type carboxysomes (beta-cyanobacteria). Potential functional differences between the two types are not yet fully understood. In addition to these proteins there are several homologous shell proteins including those found in pdu organelles involved in coenzyme B12-dependent degradation of 1,2-propanediol and eut organelles involved in the cobalamin-dependent degradation of ethanolamine. Structure evidence shows that several carboxysome shell proteins and their homologs (Csos1A, CcmK1,2,4, and PduU) exist as hexamers which might further assemble into extended, tightly packed layers hypothesized to represent the flat facets of the polyhedral organelles outer shell. Although it has been suggested that other homologous proteins in this family might also form hexamers and play similar functional roles in the construction of their corresponding organelle outer shells at present no experimental evidence directly supports this view.

Carbon dioxide concentrating mechanism (CcmK); Bacterial Micro-Compartment (BMC) domain; CcmK1-4 and CcmL proteins found in Synechocystis sp. strain PCC 6803 make up the beta carboxysome shell. These CcmK proteins have been shown to form hexameric units, while the CcmL proteins have been shown to form pentameric units. Together these proteins further assemble into the flat facets of the polyhedral carboxysome shell. The structures suggest that the central pores and the gaps between hexamers limit the transport of metabolites into and out of the the carboxysome.

1,2-propanediol utilization protein T (PduT), Bacterial Micro-Compartment (BMC) domain repeat 1; PduT proteins are homologs of the carboxysome shell protein. They are encoded within the pdu operon and might be required for the formation of the outer shell of the bacterial pdu polyhedral organelles which are involved in coenzyme B12-dependent degradation of 1,2-propanediol. Although it has been suggested that PduT might form hexamers and further assemble into the flat facets of the polyhedral outer shell of pdu organelles at present no experimental evidence directly supports this view. PduT proteins contain two tandem BMC domains repeats. This CD contains repeat 1 (the first BMC domain of PduT) as well as carboxysome shell protein sequence homolog, EutM protein, are also included in this CD. They too might exist as hexamers and might play similar functional roles in the construction of the eut organelle outer shell which still remains poorly understood.

Carboxysome Shell 1 (CsoS1); Bacterial Micro-Compartment (BMC) domain; The cso operon in Halothiobacillus neapolitanus contains the genes involved in alpha carboxysome function including those for the carboxysome shell proteins: CsoS1A, CsoS1B, and CsoS1C. CsoS1A has been shown to form hexameric units which further assemble into the flat facets of the polyhedral carboxysome shell. The structures suggest that the central pores and the gaps between hexamers limit the transport of metabolites into and out of the the carboxysome. Although it has been suggested that other homologous proteins, CsoS1B and CsoS1C, in this family might also form hexamers and play similar functional roles in the construction of carboxysome outer shell at present no experimental evidence directly supports this view.
