522448:FRE64 RS14450
gene id: 522448:FRE64_RS14450
uniprot id: A0A5B8NPU1
names: Cofactor
names: Function
names: Subcellular Location Annotation
names: Subunit
messages: 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.
messages: Binds 2 [4Fe-4S] clusters. Cluster 2 is most probably the spectroscopically characterized electron acceptor FA and cluster 1 is most probably FB.
messages: Cellular thylakoid membrane
messages: 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.

gene id: 522448:FRE64_RS07035
uniprot id: A0A5B8NMD7
names: Domain
names: Function
names: Similarity
names: Subcellular Location Annotation
names: Subunit
messages: Belongs to the bacterial microcompartments protein family. CcmK subfamily.
messages: Carboxysome
messages: Homohexamer. Interacts with CcmN and CcmO in the carboxysome.
messages: 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.
messages: The tight homohexamer forms a small pore which is positively charged.

names: Function
names: Similarity
names: Subcellular Location Annotation
names: Subunit
messages: Belongs to the PsbL family.
messages: Cellular thylakoid membrane
messages: Cyanobacteriotal PSII is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Ycf12, at least 3 peripheral proteins PsbO, PsbU, PsbV and a large number of cofactors. It forms dimeric complexes.
messages: Membrane
messages: 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.
