Bacterial flagella are comprised of ~20,000 repeating subunits called flagellin and are synthesized by transporting unfolded flagellin monomers through the central channel of the flagellar filament to the distal end where they are folded and incorporated into the growing structure. The transport mechanism is predicted to be facilitated by a hydrophilic coating of amino acid side chains on the inside wall of the central channel that repels the mostly hydrophobic surface of the unfolded flagellin monomer. The lack of interaction between the flagellin monomer and the central channel wall is thought to allow for the passive diffusion of protein monomers. …
