[[http://www.uniprot.org/uniprot/B_BPPHX B_BPPHX]] Participates in the assembly of the viral procapsid in the cytoplasm. Forms first a 12S pre-assembly complex with protein H, and F and G pentamers, then twelve 12S complexes are joined by the D protein to form the procapsid. Internal scaffold protein B is released from the procapsid upon genome packaging, possibly through affinity displacement by the protein J, or by proteolysis. [[http://www.uniprot.org/uniprot/D_BPPHX D_BPPHX]] Assembles the procapsid by joining twelve 12S pre-assembly complex into a T=1 icosahedral particle, called 108S procapsid. Ten proteins D bind each 12S complex, which are formed by three pentamers of F, G, B protein and a H protein. The scaffolding protein is released from the provirion after genome packaging to form the mature virion.<ref>PMID:159449</ref> <ref>PMID:15890913</ref> [[http://www.uniprot.org/uniprot/G_BPPHX G_BPPHX]] Attaches the circulating virion to the bacterial lipopolysaccharides which serve as receptor for the virus. Determines the phage host-range. Probably triggers with protein H the injection of the phage DNA into the host cytoplasm upon conformational changes induced by the interaction with host lipopolysaccharides.<ref>PMID:10739948</ref> <ref>PMID:14553915</ref> [[http://www.uniprot.org/uniprot/F_BPPHX F_BPPHX]] Assembles to form an icosahedral capsid with a T=1 symmetry, about 30 nm in diameter, and consisting of 60 capsid proteins F.<ref>PMID:11991963</ref> | |||
