[https://www.uniprot.org/uniprot/BMCP_HALO1 BMCP_HALO1] Forms vertices in bacterial microcompartment (BMC) shells. Expression of 5 proteins in E.coli (BMC-H (Hoch_5815), BMC-P (Hoch_5814), and 3 BMC-T (Hoch_5812, Hoch_5816, Hoch_3341)) forms 40 nm artificial BMC with a molecular mass of 6.5 MDa. There are 12 BMC-P pentamers per BMC. The shell facets are 20-30 Angstroms thick, with 1 of BMC-T trimers protruding to the exterior.<ref>PMID:28642439</ref> <ref>PMID:30833088</ref>

Bacterial microcompartments (BMCs) are composed of an enzymatic core encapsulated by a selectively permeable protein shell that enhances catalytic efficiency. Many pathogenic bacteria derive competitive advantages from their BMC-based catabolism, implicating BMCs as drug targets. BMC shells are of interest for bioengineering due to their diverse and selective permeability properties and because they self-assemble. A complete understanding of shell composition and organization is a prerequisite for biotechnological applications. Here, we report the cryoelectron microscopy structure of a BMC shell at 3.0-A resolution, using an image-processing strategy that allowed us to determine the previously uncharacterized structural details of the interactions formed by the BMC-T(S) and BMC-T(D) shell subunits in the context of the assembled shell. We found unexpected structural plasticity among these interactions, resulting in distinct shell populations assembled from varying numbers of the BMC-T(S) and BMC-T(D) subunits. We discuss the implications of these findings on shell assembly and function.
