Many bacteria glide smoothly on surfaces, despite having no discernable propulsive organelles on their surface. Recent experiments with <em>Myxococcus xanthusem> and <em>Flavobacterium johnsoniaeem> show that both of these distantly related bacterial species glide using proteins that move in helical tracks, albeit with significantly different motility mechanisms. Both species utilize proton-motive force for movement. Although the motors that power gliding in <em>M.聽xanthusem> have been identified, the <em>F.聽johnsoniaeem> motors remain to be discovered.
