Flagellins polymerise to form bacterial flagella. There is some similarity between this entry and Pfam:PF00669, particularly the motif NRFXSXIXXL. It has been suggested that these two regions associate [2] and this is shown to be correct as structurally this domain forms an extended helix that interacts with the N-terminal region (Pfam:PF00669) to form the D0 and D1 structural domains [3]. These domains are responsible for the activation of TLR5, with the C-terminal D0 region playing a key role [4-6].

Flagellar hook-associated protein 1, D2-like domain
This entry includes Flagellar hook-associated protein 1 (FlgK or HAP1), one of three HAPs that form the hook-filament junction and has structural similarity to flagellin. FlgK is required for normal flagellum assembly. Proteins in this entry have a m ...
This entry includes Flagellar hook-associated protein 1 (FlgK or HAP1), one of three HAPs that form the hook-filament junction and has structural similarity to flagellin. FlgK is required for normal flagellum assembly. Proteins in this entry have a multidomain fold comprising an elongated alpha-helical scaffold core, and depending on the bacterial species, a variable number of smaller domains [1]. This entry represents a beta-sandwich domain from FlgK proteins; Salmonella typhimurium FlgK (Swiss:P0A1J5) has one beta-sandwich domain, while FlgK from Burkholderia pseudomallei has two of them protruding from the alpha-helical core, referred to as D2 and D3 domains in [1], of which the first one, D2, is covered in this entry [1]. FlgK has cytotoxic effects suggesting an important role in pathogenesis and is highly immunogenic. Domains D2 and D3 from B. pseudomallei have been identified as epitopes with increased immunogenic potential for vaccine development.
Flagellar hook-associated protein FlgK helical domain
This entry represents a mainly helical domain found in flagellar hook-associated protein FlgK and related proteins. FlgK is one of three hook associated proteins that form the hook-filament junction. This domain adopts a broken antiparallel helical b ...
This entry represents a mainly helical domain found in flagellar hook-associated protein FlgK and related proteins. FlgK is one of three hook associated proteins that form the hook-filament junction. This domain adopts a broken antiparallel helical bundle comprising six helical segments [1-2].
This entry represents a barrel domain of flagellins FliC and FljB, which have a boomerang-shape with one arm composed of domain D1 and the other formed by D2 and D3 [1-3]. This entry corresponds to to subdomain D2b described in [4].
Flagellar basal body rod FlgEFG protein C-terminal
This family consists of a number of C-terminal domains of unknown function. This domain seems to be specific to flagellar basal-body rod and flagellar hook proteins in which Pfam:PF00460 is often present at the extreme N terminus.
This entry represents the D1 domain found in three closely related flagellar proteins usually denoted FlgE, FlgF and FlgG. In FlgE there is an additional domain (D2, Pfam:PF07559) outside D1 [1-5]. The flagellar hook is a short, highly curved tubular ...
This entry represents the D1 domain found in three closely related flagellar proteins usually denoted FlgE, FlgF and FlgG. In FlgE there is an additional domain (D2, Pfam:PF07559) outside D1 [1-5]. The flagellar hook is a short, highly curved tubular structure that connects the flagellar motor to the long filament acting as a helical propeller.
