It has been widely assumed that the atomic structure of the flagellar filament from Salmonella typhimurium serves as a model for all bacterial flagellar filaments given the sequence conservation in the coiled-coil regions responsible for polymerization. On the basis of electron microscopic images, we show that the flagellar filaments from Campylobacter jejuni have seven protofilaments rather than the 11 in S. typhimurium. The vertebrate Toll-like receptor 5 (TLR5) recognizes a region of… 
Complete structure of the bacterial flagellar hook reveals extensive set of stabilizing interactions
TLDR
The structure of the hook from Campylobacter jejuni is reported by cryo-electron microscopy and it is shown that the hook is stabilized by intricate inter-molecular interactions between FlgE molecules.
Atomic structure of the Campylobacter jejuni flagellar filament reveals how ε Proteobacteria escaped Toll-like receptor 5 surveillance
TLDR
The essential role of glycosylation in C. jejuni motility is explained, and how the outer domains have evolved to play a role not previously found in other bacteria is shown.
A structural model of flagellar filament switching across multiple bacterial species
TLDR
Near-atomic resolution cryo-EM structures for flagellar filaments from both Gram-positive Bacillus subtilis and Gram-negative Pseudomonas aeruginosa are presented and detailed information about the molecular interactions in two filament states is successfully predicted to predict point mutations that shift the equilibrium between those two states.
The cryo-EM structure of the bacterial flagellum cap complex suggests a molecular mechanism for filament elongation
TLDR
The cryo-EM structure of the Campylobacter jejuni cap complex is presented, which reveals that FliD is pentameric, with the N-terminal region of the protomer forming an extensive set of contacts across several subunits, that contribute to Fli D oligomerization.
Archaeal flagellin combines a bacterial type IV pilin domain with an Ig-like domain
TLDR
The structure of a flagellar-like filament from an archaeon is determined using cryo-EM and how it has evolved combining domains from two different protein families is shown, providing insights into how motile systems can arise by convergent evolution.
Structural insights into bacterial flagellar hooks similarities and specificities
TLDR
It is shown that a special strain of Salmonella enterica, which was designed to encode a gene of flgE that has the extra domains found in FlgE from C. jejuni, is fully motile and seems that no matter the size of the hook protein, the hook will always have a structure made of 11 protofilaments.
Bacterial flagellar capping proteins adopt diverse oligomeric states
TLDR
Pseudomonas FliD exhibits unexpected structural similarity to other flagellar proteins at the domain level, adopts a unique hexameric oligomeric state, and depends on flexible determinants for oligomerization.

Complete atomic model of the bacterial flagellar filament by electron cryomicroscopy
TLDR
A complete atomic model of the R-type filament by electron cryomicroscopy reveals intricate molecular packing and an α-helical coiled coil formed by the terminal chains in the inner core of the filament, with its intersubunit hydrophobic interactions having an important role in stabilizing the filament.
Structure and switching of bacterial flagellar filaments studied by X-ray fiber diffraction
TLDR
Based on the measured helical parameters of the L and R lattices and the switching model, the twist and curvature calculated for the ten possible supercoils are in quantitative accord with observed supercoiled forms of flagellar filaments.
Evasion of Toll-like receptor 5 by flagellated bacteria.
TLDR
The results suggest that TLR5 evasion is critical for the survival of this subset of bacteria at mucosal sites in animals and raise the intriguing possibility that flagellin receptors provided the selective force to drive the evolution of these unique subclasses of bacterial flageLLins.
Toll-like receptor 5 recognizes a conserved site on flagellin required for protofilament formation and bacterial motility
TLDR
The exquisite ability of the innate immune system to precisely target a conserved site on flagellin that is essential for bacterial motility is demonstrated.
The structure of bacterial ParM filaments
TLDR
Using cryo-EM and three-dimensional reconstruction, it is shown that ParM filaments have a different structure from F-actin, with very different subunit-subunit interfaces, and that this involves domain-domain rotations within the ParM subunit.
Role of two flagellin genes in Campylobacter motility
TLDR
Although the wild-type flagellar filament is a heteropolymer of the flaA andflaB gene products, immunogold electron microscopy suggests that flaB epitopes are poorly surface exposed along the length of theWild-type filament.
