Gliding Motility: Anticipating the Next Move with a Molecular Clock
نویسنده
چکیده
FrzS protein is important for normal social motility in myxobacteria, which includes periodic reversals in the direction of cell motion. Recent results show that cell reversal correlates with the migration of FrzS from the old leading pole of the cell to the new leading pole.

New insights into the function of a versatile class of membrane molecular motors from studies of Myxococcus xanthus surface (gliding) motility
Cell motility is a central function of living cells, as it empowers colonization of new environmental niches, cooperation, and development of multicellular organisms. This process is achieved by complex yet precise energy-consuming machineries in both eukaryotes and bacteria. Bacteria move on surfaces using extracellular appendages such as flagella and pili but also by a less-understood process...
متن کاملGenetic and molecular analysis of cglB, a gene essential for single-cell gliding in Myxococcus xanthus.
Gliding movements of individual isolated Myxococcus xanthus cells depend on the genes of the A-motility system (agl and cgl genes). Mutants carrying defects in those genes are unable to translocate as isolated cells on solid surfaces. The motility defect of cgl mutants can be transiently restored to wild type by extracellular complementation upon mixing mutant cells with wild-type or other moti...
متن کاملThe junctional pore complex, a prokaryotic secretion organelle, is the molecular motor underlying gliding motility in cyanobacteria
BACKGROUND Whereas most bacteria move by means of flagella, some prokaryotes move by gliding. In cyanobacteria, gliding motility is a slow uniform motion which is invariably accompanied by a continuous secretion of slime. On the basis of these characteristics, a model has been proposed in which the gliding motility of cyanobacteria depends on the steady secretion of slime using specific pores, ...
متن کاملGliding motility in bacteria: insights from studies of Myxococcus xanthus.
Gliding motility is observed in a large variety of phylogenetically unrelated bacteria. Gliding provides a means for microbes to travel in environments with a low water content, such as might be found in biofilms, microbial mats, and soil. Gliding is defined as the movement of a cell on a surface in the direction of the long axis of the cell. Because this definition is operational and not mecha...
متن کاملActin depolymerizing factor controls actin turnover and gliding motility in Toxoplasma gondii
Apicomplexan parasites rely on actin-based gliding motility to move across the substratum, cross biological barriers, and invade their host cells. Gliding motility depends on polymerization of parasite actin filaments, yet ∼98% of actin is nonfilamentous in resting parasites. Previous studies suggest that the lack of actin filaments in the parasite is due to inherent instability, leaving uncert...
