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.

PF06429Flagellar basal body rod FlgEFG protein C-terminal (Flg_bbr_C)Flagellar basal body rod FlgEFG protein C-terminalThis 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. Domain

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].
