Popis:	It is proposed that gliding motility in bacteria is based on rotary assemblies located in the cell envelope and that these assemblies may be analogous to basal regions of bacterial flagella. This proposal rests on the following evidence: (i) Structures resembling flagellar basal regions have been demonstrated in cells ofCytophaga johnsonae andFlexibacter columnaris, and such structures are absent from one nonmotile mutant ofF. columnaris. (ii) The effects of inhibitors of energy metabolism on gliding motility are identical with their effects on prokaryotic fiagellar motility. (iii) The active movement of latex spheres along surfaces of gliding bacteria appears to depend on mechanisms responsible for motility and can be explained by the presence of rotary surface assemblies.
