[[Category: Kerfeld | [https://www.uniprot.org/uniprot/BMCT2_HALO1 BMCT2_HALO1] A minor component of the bacterial microcompartment (BMC) shell. 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 BMCs with a molecular mass of 6.5 MDa. One of 2 stacked pseudohexamers in the BMC. There are 20 BMC-T pseudohexamers per BMC, composed of mixed BMC-T1, BMC-T2 and BMC-T3. The shell facets are 20-30 Angstroms thick, with 1 of the stacked BMC-T trimers protruding to the exterior (PubMed:28642439, PubMed:30833088). The stacked trimers may serve as conduits to allow chemical flux across the protein shell, gated by Arg-70 which contacts Glu-69 in an adjacent subunit; they are flexible enough to play a role in accommodating variations in shell assembly (Probable).<ref>PMID:28642439</ref> <ref>PMID:30833088</ref> <ref>PMID:30833088</ref> | ||
