Movement of microtubules by single kinesin molecules

Nature. 1989 Nov 9;342(6246):154-8. doi: 10.1038/342154a0.

Abstract

Kinesin is a motor protein that uses energy derived from ATP hydrolysis to move organelles along microtubules. Using a new technique for measuring the movement produced in vitro by individual kinesin molecules, it is shown that a single kinesin molecule can move a microtubule for several micrometers. New information about the mechanism of force generation by kinesin is presented.
