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

open access: yesResults 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 Master equation approach to modeling an artificial protein motor

open access: yes, 2010
Linear bio-molecular motors move unidirectionally along a track by coordinating several different processes, such as fuel (ATP) capture, hydrolysis, conformational changes, binding and unbinding from a track, and center-of-mass diffusion.

Elastically coupled molecular motors

open access: yes, 1998
We study the influence of filament elasticity on the motion of collective molecular motors. It is found that for a backbone flexibility exceeding a characteristic value (motor stiffness divided through the mean displacement between attached motors), the ...

Dynamic curvature regulation accounts for the symmetric and asymmetric beats of Chlamydomonas flagella

open access: yeseLife, 2016
Cilia and flagella are model systems for studying how mechanical forces control morphology. The periodic bending motion of cilia and flagella is thought to arise from mechanical feedback: dynein motors generate sliding forces that bend the flagellum, and

Interaction of molecular motors can enhance their efficiency

open access: yes, 2010
Particles moving in oscillating potential with broken mirror symmetry are considered. We calculate their energetic efficiency, when acting as molecular motors carrying a load against external force. It is shown that interaction between particles enhances

Transport by molecular motors in the presence of static defects [PDF]

open access: yes, 2009
The transport by molecular motors along cytoskeletal filaments is studied theoretically in the presence of static defects. The movements of single motors are described as biased random walks along the filament as well as binding to and unbinding from the

An electric molecular motor

open access: yesNature, 2023
AbstractMacroscopic electric motors continue to have a large impact on almost every aspect of modern society. Consequently, the effort towards developing molecular motors1–3 that can be driven by electricity could not be more timely. Here we describe an electric molecular motor based on a [3]catenane4,5, in which two cyclobis(paraquat-p-phenylene)6 ...

Cluster models of molecular motors: kinesin and myosin V [PDF]

open access: yesКомпьютерные исследования и моделирование, 2014
We present a semiphenomenological model of the two molecular motors: kinesin and myosin V, which play a great role in intracellular transport. The temporal dynamics of changes in the characteristic geometric parameters and the elastic stresses generated ...

Long-Time Dynamics of Selected Molecular-Motor Components Using a Physics-Based Coarse-Grained Approach

open access: yesBiomolecules, 2023
Molecular motors are essential for the movement and transportation of macromolecules in living organisms. Among them, rotatory motors are particularly efficient.
