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
