Abstract

The bacterial flagellum represents one of the best understood molecular machines. Comprised of 40 parts that self-assemble into a true rotary engine, the biochemistry and genetics of these systems has revealed an unanticipated complexity. An essential component to assembly is the subset of parts that function as a protein secretory pump to ensure and discriminate that the correct number of protein subunits and their order of secretion is precisely regulated during assembly. Of further interest is the recognition of late that a number of important plant and animal pathogens use a related protein secretory pump fused to a membrane-spanning needle-like syringe by which a subset of toxins can be injecte
