“…The beads were carried by the cells, maintaining their same attached positions, indicating that the cells do not roll around the cell axis during gliding. In the bacteria that glide independently of their appendages, the surface movement can be visualized when a bead is attached to the cell surface [14,15]. However, our observations indicated that the cell surface does not move during M. mobile gliding.…”

Mycoplasma mobile cells glide on solid surfaces such as glass with a fast and continuous motion in the direction of the membrane protrusion (head-like structure) at one cell pole. To examine its cell-surface movement, a latex bead was attached to a cell and behavior in gliding was monitored. The bead was carried without movement relative to the cell body, suggesting that the cell does not roll around the cell axis and the surface movement is limited to a small area. A small percentage of cells showed an elongated head-like structure in an old batch culture. The head-like structure moved forward, sometimes leaving the cell body in one position, resulting in a stretching of this head-like structure. These results indicate that the head-like structure drags the cell body, leading us to conclude that the force for gliding is generated at the head-like structure.

“…44 A variety of gliding motility models have been proposed on the Cytophaga-Flavobacterium group, one of which is a ratchet structure. 39,45 In this model, proteins locating in the cytoplasmic membrane and periplasm propel the outer membrane proteins along tracks anchored to the peptidoglycan. 46 Although similarity of gliding motility features to the Cytophaga-Flavobacterium group were implied in Saprospira grandis, 24 no conclusive mechanisms have been proposed to date.…”

The Saprospira sp. strain SS98-5 cells form colonies on a nutrient-rich agar medium, but are motile by gliding under low-nutrient condition and then numerous microtubule-like fibril structures are found intracellularly. The fibril structures are composed of a proteinous subunit SCFP; this gene was cloned previously. Here, the organization of ORFs adjacent to the SS98-5 SCFP gene and its transcription were investigated, and a SCFP gene homolog was cloned from Saprospira sp. SS03-4, a relative strain of SS98-5. The SCFP gene was also encoded within the SS03-4 chromosome, and grouped into a phage tail sheath protein family, suggesting its bacteriophage genome origin. Four ORFs adjacent to the SCFP gene were identified and their organization was in common with several prokaryotes. The SCFP mRNA was detected by reverse transcriptase polymerase chain reaction from gliding and non-gliding cells, implying that the SCFP gene was transcribed independent of existence or absence of the fibril structures.

“…However, F. johnsoniae glides about 50 times faster than M. xanthus and can move on a much wider range of surfaces (McBride and Nakane, 2015). F. johnsoniae cells, besides gliding along their long axes, sometimes lift one end off a glass surface, rotate their cell bodies around the other end (pivoting) or flip their cell bodies over (Lapidus and Berg, 1982). PMF was determined to be the energy source for flavobacterial gliding (Pate and Chang, 1979).…”

Summary For many bacteria, motility is essential for survival, growth, virulence, biofilm formation and intra/interspecies interactions. Since natural environments differ, bacteria have evolved remarkable motility systems to adapt, including swimming in aqueous media, and swarming, twitching and gliding on solid and semi-solid surfaces. Although tremendous advances have been achieved in understanding swimming and swarming motilities powered by flagella, and twitching motility powered by Type IV pili, little is known about gliding motility. Bacterial gliders are a heterogeneous group containing diverse bacteria that utilize surface motilities that do not depend on traditional flagella or pili, but are powered by mechanisms that are less well understood. Recently, advances in our understanding of the molecular machineries for several gliding bacteria revealed the roles of modified ion channels, secretion systems and unique machinery for surface movements. These novel mechanisms provide rich source materials for studying the function and evolution of complex microbial nano-machines. In this review, we summarize recent findings made on the gliding mechanisms of the myxobacteria, flavobacteria and mycoplasmas.
