== Function ==
[https://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>
