Inoue and Kinoshita et al. report an important role for the flexible linker of the major flagellar export apparatus protein FlhA (FlhAL) in regulating the switch from secretion of hook-type to filament-type components. The data presented here improve our understanding of the complex process of bacterial flagellar assembly.
