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 ...

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 ...

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.

Molecular motors: nature's nanomachines
IEE Proceedings - Nanobiotechnology, 2003Molecular 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

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

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

Molecular Motors: Cooperative Phenomena of Multiple Molecular Motors
2014Transport of various types of cargoes in cells is based on molecular motors moving along the cytoskeleton. Often, these motors work in teams rather than as isolated molecules. This chapter discusses analytical and computational approaches to study the cooperation of multiple molecular motors theoretically.
