The Kinesin Linear Motor

01:1112 Mar, 2010

http://creation.com Inside a living cell is an amazing transportation system. Proteins have to be delivered to the correct part of the cell to perform their intended functions. This animation, based on a lot of clever research over a number of years, shows how it happens.

Highways, made of microtubules, are assembled by interlocking proteins, each manufactured in accordance with the coded instructions on the cell's DNA. Marching along a microtubule is the kinesin motor, the hero of our story, carrying a huge sack of proteins to be delivered to a pre-determined place in the cell. Here the proteins will be released to fulfil their functions.

A kinesin linear motor uses one ATP to provide the energy for each step and takes 125,000 steps to cover one millimetre!

This amazing machine shows all the hallmarks of design! http://creation.com
