Abstract

When motile swarmer cells of differentiate into sessile stalked cells, the flagellum is ejected. To elucidate the molecular mechanism of the flagellar ejection, flagellar hook–basal body (HBB) complexes from were purified and characterized. The purified HBBs were less stable against acidic pH or protease treatment than HBBs of , supporting the view that flagellar ejection from is initiated by destruction of the fragile basal structures. In addition, protease treatment of the purified flagella resulted in the specific digestion of the MS ring complex, revealing for the first time the intact structure of the whole rod.
