Stabilizes the binding of IF-2 and IF-3 on the 30S subunit to which N-formylmethionyl-tRNA(fMet) subsequently binds. Helps modulate mRNA selection, yielding the 30S pre-initiation complex (PIC). Upon addition of the 50S ribosomal subunit IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex. http://togogenome.org/gene/2016057:OXH18_RS19475 ^@ http://purl.uniprot.org/uniprot/A0A9E8ZAP7 ^@ Similarity ^@ Belongs to the bacterial ribosomal protein bS21 family. http://togogenome.org/gene/2016057:OXH18_RS11900 ^@ http://purl.uniprot.org/uniprot/A0A9E9CAB0 ^@ Cofactor|||Function|||Similarity|||Subcellular Location Annotation|||Subunit ^@ Belongs to the PsbE/PsbF family.|||Cellular thylakoid membrane|||Heterodimer of an alpha subunit and a beta subunit.

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.
