Bacterial flagellar motor
What do you think of the state of biology today? It has indeed changed in many ways, and to the good. Molecular biology has come into its own and provides enormous power to answer new and old questions in such areas as development, physiology, and cell biology. The use of mathematical tools has become increasingly effective in shedding light on ecological and evolutionary problems, and other ma...
متن کاملBacterial flagellar motor.
The bacterial flagellar motor is a reversible rotary nano-machine, about 45 nm in diameter, embedded in the bacterial cell envelope. It is powered by the flux of H+ or Na+ ions across the cytoplasmic membrane driven by an electrochemical gradient, the proton-motive force or the sodium-motive force. Each motor rotates a helical filament at several hundreds of revolutions per second (hertz). In m...
متن کاملBacterial Flagella: Flagellar Motor
Many species of bacteria actively seek out favourable conditions for growth by swimming up gradients of nutrients, oxygen, light or other attractants, or down gradients away from toxic substances (repellants). Different species employ several different modes of swimming, almost all of which are driven by the rapid rotation of helical flagellar filaments that protrude from the cell. Rotation of ...
متن کاملFlagellar motility in bacteria structure and function of flagellar motor.
Bacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments. At the base of each flagellum, a reversible rotary motor, which is powered by the proton- or the sodium-motive force, is embedded in the cell envelope. The motor consists of two parts: the rotating part,...
متن کاملDomain-based biophysical characterization of the structural and thermal stability of FliG, an essential rotor component of the Na+-driven flagellar motor
Many bacteria move using their flagellar motor, which generates torque through the interaction between the stator and rotor. The most important component of the rotor for torque generation is FliG. FliG consists of three domains: FliGN, FliGM, and FliGC. FliGC contains a site(s) that interacts with the stator. In this study, we examined the physical properties of three FliG constructs, FliGFull...
