title: Spinning tails.
abstract: The torque-generating, direction-reversing switch proteins of the bacterial flagellar rotary motor form a cytoplasmic extension of the bacterial flagellar basal body. 10 A maps, obtained by electron cryomicroscopy, of the bacterial filament reveal an unusual alpha domain which forms the protein-subunit export channel. The details of subunit export, assembly, and assembly-monitoring machinery are becoming clearer.
