It forms dimeric complexes.|||Membrane|||One of the components of the core complex of photosystem II (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. This subunit is found at the monomer-monomer interface and is required for correct PSII assembly and/or dimerization. http://togogenome.org/gene/522448:FRE64_RS14450 ^@ http://purl.uniprot.org/uniprot/A0A5B8NPU1 ^@ Cofactor|||Function|||Subcellular Location Annotation|||Subunit ^@ Apoprotein for the two 4Fe-4S centers FA and FB of photosystem I (PSI); essential for photochemical activity. FB is the terminal electron acceptor of PSI, donating electrons to ferredoxin. The C-terminus interacts with PsaA/B/D and helps assemble the protein into the PSI complex. Required for binding of PsaD and PsaE to PSI. PSI is a plastocyanin/cytochrome c6-ferredoxin oxidoreductase, converting photonic excitation into a charge separation, which transfers an electron from the donor P700 chlorophyll pair to the spectroscopically characterized acceptors A0, A1, FX, FA and FB in turn.|||Binds 2 [4Fe-4S] clusters. Cluster 2 is most probably the spectroscopically characterized electron acceptor FA and cluster 1 is most probably FB.|||Cellular thylakoid membrane|||The cyanobacterial PSI reaction center is composed of one copy each of PsaA,B,C,D,E,F,I,J,K,L,M and X, and forms trimeric complexes. http://togogenome.org/gene/522448:FRE64_RS07035 ^@ http://purl.uniprot.org/uniprot/A0A5B8NMD7 ^@ Domain|||Function|||Similarity|||Subcellular Location Annotation|||Subunit ^@ Belongs to the bacterial microcompartments protein family. CcmK subfamily.|||Carboxysome|||Homohexamer. Interacts with CcmN and CcmO in the carboxysome.|||One of the shell proteins of the carboxysome, a polyhedral inclusion where RuBisCO (ribulose bisphosphate carboxylase, rbcL-rbcS) is sequestered. Assembles into hexamers which make sheets that form the facets of the polyhedral carboxysome. The hexamer central pore probably regulates metabolite flux.|||The tight homohexamer forms a small pore which is positively charged.
