Mechanisms of microtubule dynamics and force generation examined with computational modeling and electron cryotomography
Microtubules are dynamic tubulin polymers which elongate by addition of bent guanosine triphosphate tubulin to the tips of curving protofilaments. Here authors use Brownian dynamics modeling and electron cryotomography to show that the lateral activation energy barrier in tubulin-tubulin interaction...

| Sumario: | Microtubules are dynamic tubulin polymers which elongate by addition of bent guanosine triphosphate tubulin to the tips of curving protofilaments. Here authors use Brownian dynamics modeling and electron cryotomography to show that the lateral activation energy barrier in tubulin-tubulin interactions is a key parameter for this process, controlling the development of high pulling forces. |
