Cooperative Molecular Motors

Physical Review Letters, 1995
We present a simple stochastical model for motor molecules that cooperate in large groups. This model could apply for actin-myosin motors in muscles and for motility assays with a high concentration of motor molecules. We calculate the dependence of the velocity on the applied force as a function of ATP concentration and show the existence of a ...

Molecular Rotary Motors

Science, 1999
ATP is the energy currency of the cell: hydrolysis of ATP into ADP and inorganic phosphate (P) releases energy. The enzyme responsible for generating this energy currency is the ATP synthase. In a Perspective, [Fillingame][1] discusses two new reports ([ Sambongi et al. ][2] and [ Stock et al.

Molecular Pumps and Motors

Journal of the American Chemical Society, 2021
Pumps and motors are essential components of the world as we know it. From the complex proteins that sustain our cells, to the mechanical marvels that power industries, much we take for granted is only possible because of pumps and motors. Although molecular pumps and motors have supported life for eons, it is only recently that chemists have made ...

Molecular Motors

2007
Abstract Every biologist has seen it and marveled. Some watch it for hours, spell-bound. Take an individual living cell—a human skin cell, for example and put it under a powerful microscope. What comes into view is a far cry from the vague “protoplasm,” the so-called living jelly, “the stuff of life” that was taught in high school ...

Rotary Molecular Motors

2005
The F-, V-, and A-adenosine triphosphatases (ATPases) represent a family of evolutionarily related ion pumps found in every living cell. They either function to synthesize adenosine triphosphate (ATP) at the expense of an ion gradient or they act as primary ion pumps establishing transmembrane ion motive force at the expense of ATP hydrolysis.

Ion-age molecular motors

Nature Neuroscience, 2001
The hypothesis that prestin is the molecular motor in outer hair cells has been strengthened by a recent paper in Science identifying an unusual molecular mechanism for the effect.

Molecular motors: nature's nanomachines

IEE Proceedings - Nanobiotechnology, 2003
Molecular motors are protein-based machines that convert chemical potential energy into mechanical work. This paper aims to introduce the non-specialist reader to molecular motors, in particular, acto-myosin, the prototype system for motor protein studies. These motors produce their driving force from changes in chemical potential arising directly from

DNA based molecular motors

Physics of Life Reviews, 2009
Most of the essential cellular processes such as polymerisation reactions, gene expression and regulation are governed by mechanical processes. Controlled mechanical investigations of these processes are therefore required in order to take our understanding of molecular biology to the next level. Single-molecule manipulation and force spectroscopy have

How molecular motors work

Nature, 1994
What is the molecular basis of cell movement and changes in cell shape? The integration of three approaches is revealing how the molecular motors that drive these processes move and produce force.

MOVEMENTS OF MOLECULAR MOTORS

Biological Physics 2000, 2001
The movements of cytoskeletal motors such as kinesin or myosin V cover many length and time scales. When such a motor is bound to a filament, the consumption of a single fuel molecule leads to a certain motor displacement or step which is of the order of several nanometers. The motor typically makes about a hundred such steps in its bound state and, in
