細菌べん毛繊維は分子間相互作用とフラストレーションを利用して超らせん構造の変化を制御する

The bacterial flagellar filament controls the swimming mode of bacteria by its polymorphic structural change. We investigated dynamics of the flagellar filament by massive molecular dynamic simulation and found that three types of inter-molecular interactions, permanent, sliding and switch interactions, play essential roles in the structural change. The polymorphic structure of the flagellar filament is thought to be due to energy frustration between intra- and inter-molecular interactions.
