Molecular Motors: Dynein's Gearbox
A new optical trapping study shows that the stepsize of cytoplasmic dynein varies according to the applied force, suggesting that this motor can change gear. Complementary biochemical kinetic work on yeast dynein mutants hints at the allosteric mechanisms involved.

The " Molecular Motors " Minisymposium focused mainly on the microtubule-based motors kinesin and dynein and a class V myosin. A common feature of all these motors is that they move processively on their track, meaning that the motor can take multiple steps without dissociating. A common theme of the Minisymposium was motor function in a complex intracellular environment. Kathy Trybus (Universi...
متن کاملMolecular Motors
Perhaps the most fascinating proteins that associate with the cytoskeleton are the molecular motors called motor proteins. These remarkable proteins bind to a polarized cytoskeletal filament and use the energy derived from repeated cycles of ATP hydrolysis to move steadily along it. Dozens of different motor proteins coexist in every eucaryotic cell. They differ in the type of filament they bin...
متن کاملMolecular motors
Molecular motors are responsible for almost all biologically interesting motion. They support efficient, sustained, directional motility of cellular components within cells, of entire cells over surfaces and of entire organisms. Motors allow cells to set up complex structure, and then continuously to maintain and adjust it, by directing packets of molecular components to localised, and sometime...
متن کاملSynthetic Molecular Motors
The fascinating molecular motors ubiquitous in biological systems offer a great source of inspiration for the design of artificial motors and in the quest to achieve controlled movement at the molecular level. Synthetic chemists are involved in the challenging endeavor to exploit ormimic the properties of these intriguingmolecules found in nature. Movement in biological systems can be divided i...
