Orientation-dependent electron transport in a single redox protein.

ACS nano - 24 Jan 2012

Della Pia Eduardo Antonio, Elliott Martin, Jones D Dafydd, Macdonald J Emyr

Abstract excerpt

The redox-active protein cytochrome b(562) has been engineered to introduce pairs of thiol groups in the form of cysteine residues at specified sites. Successful STM imaging of the molecules adsorbed on a gold surface indicated that one thiol group controls the orientation of the molecule and that the protein maintains its native form under the experimental conditions. Stable protein-gold STM tip electrical...
