A versatile class of cell surface directional motors gives rise to gliding motility and sporulation in Myxococcus xanthus.
Eukaryotic cells utilize an arsenal of processive transport systems to deliver macromolecules to specific subcellular sites. In prokaryotes, such transport mechanisms have only been shown to mediate gliding motility, a form of microbial surface translocation. Here, we show that the motility function...
