UniProtKB description: Together with BHP-pb3, forms the central straight fiber, bearing the receptor binding protein RBP-pb5 at its C-terminus (PubMed:36961893). Upon RBP-pb5 binding to the host receptor FhuA, the central fiber reorganizes and undergoes structural rearrangements that lead to its bending, bringing BHP-pb3 close to the host membrane for anchoring (PubMed:36961893).
