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 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 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 کاملStructural differences in the bacterial flagellar motor among bacterial species
The bacterial flagellum is a supramolecular motility machine consisting of the basal body as a rotary motor, the hook as a universal joint, and the filament as a helical propeller. Intact structures of the bacterial flagella have been observed for different bacterial species by electron cryotomography and subtomogram averaging. The core structures of the basal body consisting of the C ring, the...
