CC -!- FUNCTION: One of shell proteins of the carboxysome, a polyhedral
CC inclusion where RuBisCO (ribulose bisphosphate carboxylase, ccbL-ccbS)
CC is sequestered. Assembles into hexamers which make sheets that form the
CC facets of the polyhedral carboxysome (By similarity). The shell
CC probably limits the diffusion of CO(2) into and out of the carboxysome
CC (Probable). There are estimated to be 540 CsoS1B proteins per
CC carboxysome (Ref.4). {ECO:0000250|UniProtKB:P45689, ECO:0000269|Ref.4,
CC ECO:0000305|PubMed:18258595}.
CC -!- FUNCTION: Unlike beta-carboxysomes, alpha-carboxysomes (Cb) can form
CC without cargo protein. CsoS2 is essential for Cb formation and is also
CC capable of targeting foreign proteins to the Cb. The Cb shell assembles
CC with the aid of CsoS2; CsoS1A, CsoS1B and CsoS1C form the majority of
CC the shell while CsoS4A and CsoS4B form vertices. CsoS1D forms
CC pseudohexamers that probably control metabolite flux into and out of
CC the shell. {ECO:0000269|PubMed:33116131}.
CC -!- SUBUNIT: Homohexamer with a small central pore (By similarity).
CC Interacts with the N-terminus (residues 1-136) of RuBisCO (CbbL)
CC (PubMed:30305640). {ECO:0000250|UniProtKB:P45689,
CC ECO:0000269|PubMed:30305640}.
CC -!- SUBCELLULAR LOCATION: Carboxysome {ECO:0000269|PubMed:18258595,
CC ECO:0000305|PubMed:9696760}. Note=This bacterium makes alpha-type
CC carboxysomes. {ECO:0000269|PubMed:18258595, ECO:0000269|Ref.4,
CC ECO:0000305}.
CC -!- DOMAIN: The tight homohexamer forms a small pore which is positively
CC charged. {ECO:0000250|UniProtKB:P45689}.
CC -!- DISRUPTION PHENOTYPE: Required for growth in ambient air.
CC {ECO:0000269|PubMed:31406332}.
CC -!- BIOTECHNOLOGY: Expression of 10 genes for alpha-carboxysome (Cb)
CC proteins (cbbL-cbbS-csoS2-csoS3-csoS4A-csoS4B-csoS1C-csoS1A-csoS1B-
CC csoS1D) in E.coli generates compartments that resemble Cb, contain
CC RuBisCO and have its catalytic activity, showing it is possible to make
CC artificial, functional Cb using these 10 genes. Cargo proteins can be
CC targeted to these organelles (PubMed:22184212, PubMed:30305640).
CC Artificial Cb assembly in E.coli requires csoS2-csoS4A-csoS4B-csoS1C-
CC csoS1A-csoS1B-csoS1D (but not the gene for carbonic anhydrase, csoS3).
CC Targeting proteins to the organelle requires at least one of the CsoS2
CC C-repeats; 3 repeats gives the best localization. A nanoreactor of the
CC Cb shell proteins has been engineered which generates H(2) using a
CC ferredoxin-hydrogenase fusion (AC P07839-Q9FYU1) and a
CC flavodoxin/ferredoxin--NADP reductase (AC A0A0K3QZA5) targeted
CC separately to the Cb; the hydrogenase has first to be matured and
CC activated by HydGXEF (AC Q8EAH9, Q8EAH8, Q8EAH7 and Q8EAH6
CC respectively). Encapsulation increases H(2) production about 20% during
CC anaerobic growth, and over 4-fold more during aerobic growth
CC (PubMed:33116131). {ECO:0000269|PubMed:22184212,
CC ECO:0000269|PubMed:30305640, ECO:0000269|PubMed:33116131}.
CC -!- SIMILARITY: Belongs to the bacterial microcompartments protein family.
CC CsoS1 subfamily. {ECO:0000305}.
