Molecular Motors

by Editor1 last modified October 28, 2006 - 11:16

Molecular motors are proteins that convert chemical energy into mechanical energy (chemomechanical energy transduction) through the hydrolysis of adenosine 5′-triphosphate (ATP) or, alternatively, the translocation of ions through cellular membranes. The potential use of molecular motors as actuators and power sources for nanoelectromechanical systems (NEMS) has been widely discussed.

Examples of such motors include the protein F1-ATPase, kinesin and dynein, myosin, and RNA polymerase.
