Organic electronic element from modified cytochrome c551 and cytochrome c552

摘要

An organic electronic element material has been produced by modifying cytochrome c551 and cytochrome c552 by bonding at least a second electron transfer functional group to an amino acid residue of the cytochrome. The residue for attachment of the additional electron transfer groups could be introduced by genetic engineering or generated by chemical modification. A plurality of different electron transfer groups can be introduced to provide different redox potentials. Electron transfer can be caused to occur between the functional groups on the modified cytochromes to provide a desired electric property such as rectification, or switching in response to light.
