Video Footage of Walking Molecular Motor

Postby Izawwlgood » Mon Nov 15, 2010 5:51 pm UTC

No, I'm serious. This isn't a model, this isn't a simulation, this is actual AFM video footage of a molecular motor walking along a filament.

This is awesome. All experiments I know of to even extrapolate how this is occurring are by proxy; motors are affixed to beads, and laser trapped filaments lowered onto them, alteration of the lever arms producing differing crystal structures, cryo-EM tomography averages of thousands of motors, etc.

Nope. Here we have footage of one moving. Pretty ridiculous.

That's some pretty sweet microscopy right there. The technology behind this sort of thing has made huge strides in the past 5 years or so, and is really amazing.

Is there a way to view the video without subscribing to the journal or paying for specific article access?

Any decent university library should have access to Nature. Not sure about public libraries but its worth a shot.

Yeah sorry; I think you need journal access to see it, I should have mentioned that.

If you click the "Supplementary information" link, you should get a list of all the videos (you don't need to be logged in to download them).

Awesome! Thank you dropzone.

Here's the direct link to the pages with the videos, to slightly lessen anybody else's search:

I am legitimately really impressed. I'm going to show this to my bioengineering class, we read the paper where they finally settled the method of locomotion of myosins the other day.
