This domain is found in Flagellar hook protein FlgE from Campylobacter jejuni and similar proteins found in Epsilonproteobacteria. Around 100 copies of FlgE polymerise to form a tubular helical structure: the bacterial flagellar hook. This protein is organised into five domains. This entry represents domain D3, which is made of two discontinuous segments. It shows a set of eight beta-strands separated into two groups by two alpha-helices that form an alpha-beta barrel. This domain is not conserved in other bacterial FlgE proteins [1,2].	Domain
A	PF22692	Flagellar hook protein FlgE/F/G D1 domain (LlgE_F_G_D1)	Flagellar hook protein FlgE/F/G D1 domain	This entry represents the D1 domain found in three closely related flagellar proteins usually denoted FlgE, FlgF and FlgG.

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.	Domain

This entry consists of several bacterial FlaE flagellar proteins. These proteins are part of the flagellar basal body rod complex. FlgE comprises two domains, D1 and D2, this entry represents D2, a flattened, eight-strand beta-barrel with significant irregularity and extra loops [1,2].	Domain
