The bacterial flagellum is a complex and dynamic nanomachine that propels bacteria through liquids. It consists of a basal body, a hook, and a long filament. The flagellar filament is composed of thousands of copies of the protein flagellin (FliC) arranged helically and ending with a filament cap composed of an oligomer of the protein FliD.

In this review we will focus on the external filamentous portion of the bacterial flagellum, the structural characteristics of the axial component proteins, their role in filament assembly and polymorphism and applications in bio- and nanotechnology. Results obtained mainly with E. coli and Salmonella enterica serovar Typhimurium will be described.

2024年11月3日 · Supercoiled flagellar filaments function as mechanical propellers within the bacterial flagellum complex, playing a crucial role in motility. Flagellin, the building block of the filament,...

2017年10月16日 · Seven mutant flagellar filaments in B. subtilis and two in P. aeruginosa capture two different states of the filament. These reliable atomic models of both states reveal conserved molecular...

The bacterial flagellar filament consists of approximately 20,000 flagellins and can be several micrometers long. In this article, we reviewed the experimental works and models of flagellar filament construction and the recent findings of flagellar filament ejection during the cell cycle.

2003年8月7日 · The bacterial flagellar filament is a helical propeller for bacterial locomotion. It is a helical assembly of a single protein, flagellin, and its tubular structure is formed...

2024年11月22日 · The flagellar filament is the largest part of the flagellum and grows to a length of about 15 μm by the assembly of ~30,000 flagellin subunits with the help of the filament cap formed by five FliD subunits [86,87,88,89,90].

2021年8月2日 · It consists of a basal body, a hook, and a long filament. The flagellar filament is composed of thousands of copies of the protein flagellin (FliC) arranged helically and ending with a filament cap composed of an oligomer of the protein FliD.

2022年6月7日 · The flagellar filament of bacteria is made of single protein—flagellin—the rigidity of which is crucial to bacterial motility. The bending stiffness of the filament is frequently studied using the bacterial genus Salmonella, whose flagellin is composed of four subunit domains (D0, D1, D2, and D3).

2020年11月9日 · The bacterial flagellar filament consists of approximately 20,000 flagellins and can be several micrometers long. In this article, we reviewed the experimental works and models of flagellar filament construction and the recent findings of …
