pfam16548: FlgT_N (This model is not part of the current CDD release)
Flagellar assembly protein T, N-terminal domain
FlgT_N is the N-terminal domain of a family of flagellar proteins that make up part of the basal body of the flagellum. The flagellum is a large macromolecular assembly composed of three major parts: the basal body, the hook, and the filament. The basal body has two unique ring structures, the T ring and the H ring. FlgT is required to form and stabilise both ring structures. FlgT-N contributes to the construction of the H-ring structure, and adopts a two-layer alpha-beta sandwich architecture composed of a four-stranded anti-parallel beta-sheet and two alpha helices.
