Conductance of single molecules gives information on electron transfer

Researchers working in Wales and Denmark have used Scanning Tunnelling Microscopy (STM) to measure the conductance through single-molecules of the electron transfer protein cytochrome b562. The authors modified the protein, adding SH groups at opposite ends to allow contact with a gold surface and a Pt-Ir STM tip. They noted high conductance and conclude that this shows the importance of the heme co-factor bound to the natively structured protein in the electron transfer process.
