"A paper from David Beratan's group was featured on the October 10 cover of Physical Review Letters. Post-doctoral associate Ilya Balabin and Visiting Professor Spiros Skourits (from the University of Cyprus) working with Beratan have identified an average transition distance at which protein-mediated electron tunneling becomes dominated by thermal fluctuations of the protein. Although these fluctuations control the tunneling mechanism in most cases, the researchers find that fluctuations do not "wash out" the influence of the underlying protein fold on the kinetics. Electron transfer reactions play a central role in photosynthesis, oxidative phosphorylation, and biocatalysis.
