Sparse bayesian step-filtering for high-throughput analysis of molecular machine dynamics [PDF]

open access: yes, 2010
Nature has evolved many molecular machines such as kinesin, myosin, and the rotary flagellar motor powered by an ion current from the mitochondria. Direct observation of the step-like motion of these machines with time series from novel experimental ...

The force exerted by a molecular motor [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
The stochastic driving force exerted by a single molecular motor (e.g., a kinesin, or myosin) moving on a periodic molecular track (microtubule, actin filament, etc.) is discussed from a general viewpoint open to experimental test. An elementary “barometric” relation for the driving force is introduced that ( i

Cellular Motors for Molecular Manufacturing [PDF]

open access: yesThe 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).

Transport characteristics of molecular motors [PDF]

open access: yesBiosystems, 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.

External Stresses Affect Gonococcal Type 4 Pilus Dynamics

open access: yesFrontiers in Microbiology, 2022
Bacterial type 4 pili (T4P) are extracellular polymers that serve both as adhesins and molecular motors. Functionally, they are involved in adhesion, colony formation, twitching motility, and horizontal gene transfer.

Structural dynamics of myosin 5 during processive motion revealed by interferometric scattering microscopy

open access: yeseLife, 2015
Myosin 5a is a dual-headed molecular motor that transports cargo along actin filaments. By following the motion of individual heads with interferometric scattering microscopy at nm spatial and ms temporal precision we found that the detached head ...

A novel isoform of MAP4 organises the paraxial microtubule array required for muscle cell differentiation

open access: yeseLife, 2015
The microtubule cytoskeleton is critical for muscle cell differentiation and undergoes reorganisation into an array of paraxial microtubules, which serves as template for contractile sarcomere formation.

Effect of the Neck Linker on Processive Stepping of Kinesin Motor

open access: yesBiophysica, 2023
Kinesin motor protein, which is composed of two catalytic domains connected together by a long coiled-coil stalk via two flexible neck linkers (NLs), can step processively on a microtubule towards the plus end by hydrolyzing adenosine triphosphate (ATP ...

Transient pauses of the bacterial flagellar motor at low load

open access: yesNew Journal of Physics, 2016
The bacterial flagellar motor (BFM) is the molecular machine responsible for the swimming and chemotaxis of many species of motile bacteria. The BFM is bidirectional, and changes in the rotation direction of the motor are essential for chemotaxis. It has
