Cellular Motors for Molecular Manufacturing [PDF]

The Anatomical Record, 2007
AbstractCells are composed of macromolecular structures of various sizes that act individually or collectively to maintain their viability and perform their function within the organism. This review focuses on one structure, the microtubule, and one of the motor proteins that move along it, conventional kinesin (kinesin 1).

Third-Generation Light-Driven Symmetric Molecular Motors [PDF]

, 2017
Symmetric molecular motors based on two overcrowded alkenes with a notable absence of a stereogenic center show potential to function as novel mechanical systems in the development of more advanced nanomachines offering controlled motion over surfaces ...

First-passage times in complex energy landscapes: a case study with nonmuscle myosin II assembly

New Journal of Physics, 2022
Complex energy landscapes often arise in biological systems, e.g. for protein folding, biochemical reactions, or intracellular transport processes. Their physical effects are frequently reflected in the first-passage times (FPTs) arising from these ...

Transport characteristics of molecular motors [PDF]

Biosystems, 2008
Properties of transport of molecular motors are investigated. A simplified model based on the concept of Brownian ratchets is applied. We analyze a stochastic equation of motion by means of numerical methods. The transport is systematically studied with respect to its energetic efficiency and quality expressed by an effective diffusion coefficient.

Molecular Motors–Nature’s Efficiency at Work

Reports in Advances of Physical Sciences, 2022
Nature has generated sophisticated and very efficient molecular motors, employed for nanoscale transport at the intracellular level. As a complementary tool to nanofluidics, these motors have been envisioned for nanotechnological devices.

Molecular motors in nanobiotechnology: Protein and DNA based molecular motors: A review

Results in Chemistry
Molecular motor can be defined as the collection of a separate number of molecular features (that is, a supramolecular structure) which has been developed to carry out a function through the mechanical movements of its components, which occurs when it is

A programmable optical angle clamp for rotary molecular motors

, 2007
Optical tweezers are widely used for experimental investigation of linear molecular motors. The rates and force dependence of steps in the mechanochemical cycle of linear motors have been probed giving detailed insight into motor mechanisms. With similar
