Molecular Motors: A Theorist's Perspective
Annual Review of Physical Chemistry, 2007Individual molecular motors, or motor proteins, are enzymatic molecules that convert chemical energy, typically obtained from the hydrolysis of ATP (adenosine triphosphate), into mechanical work and motion. Processive motor proteins, such as kinesin, dynein, and certain myosins, step unidirectionally along linear tracks, specifically microtubules and ...

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

The structure of a molecular motor
Current Biology, 1993Two proteins, actin and myosin, together form a molec- ular motor that produces the work performed by mus- cle tissues, as well as many of the movements seen in all eukaryotic cells. IJntil recently, high resolution struc- tures of these two proteins have not been available.

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: 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.

Experiments are described in which the rotation of methyl groups in solids at helium temperatures is driven using external magnetic fields. The orientation of the nuclear magnetic dipoles is caused to oscillate in synchronism with coherent tunnelling rotation, switching time-dependent internal-magnetic-field gradients due to the dipole-dipole ...
