The protein complex they are studying here is the ATP Synthase, one of the coolest protein complexes in my opinion. When run in one direction, the complex uses ATP to pump H+ ions across the membrane (against the chemical gradient). When run in the other direction, it uses diffusion and H+ chemical gradients to generate ATP.
Sounds cool, but watch how it works: http://www.youtube.com/watch?v=zOSyGTYCRFw http://www.youtube.com/watch?v=zOSyGTYCRFw

Sadly, this awesome example of evolution is one of the poster-children for creationists.

The gist of it was that you plainly see the components of the engine in a needle-like syringe found in other bacteria. It had the shaft, collars and other bits.
