[[http://www.uniprot.org/uniprot/PORTL_BPP22 PORTL_BPP22]] Required for successful condensation of DNA within the capsid. Gp1 is a minor structural protein. The portal protein is present as a single ring-shaped dodecamer located at the point where tails attach. It is through this ring that DNA is thought to enter the prohead. [[http://www.uniprot.org/uniprot/FIBER_BPP22 FIBER_BPP22]] Structural component of the short non-contractile tail. The tail comprises six fibers that mediate primary attachment to the host cell lipopolysaccharides (LPS) and display endorhamnosidase enzymatic activity, hydrolyzing the alpha-1,3-O-glycosidic linkage between rhamnose and galactose of the O-antigen polysaccharide. Digestion of the LPS brings the capsid near the cell outer membrane.<ref>PMID:12837775</ref> <ref>PMID:20817910</ref> [[http://www.uniprot.org/uniprot/EXLYS_BPP22 EXLYS_BPP22]] Tail protein located at the vertex occupied by the portal ring. Together with gp10 and gp26, gp4 is required for stabilization of the condensed DNA within the capsid; perhaps by plugging the hole through which the DNA enters. Plays a role in ejection of the bacteriophage DNA into the host cell at the initiation of infection. Functions as an exolysin that catalyzes the cleavage of the glycosidic bonds between N-acetylmuramic acid and N-acetylglucosamine residues in peptidoglycans.<ref>PMID:14763988</ref>
