A Palladium‐Binding Deltarhodopsin for Light‐Activated Conversion of Protonic to Electronic Currents

Fusion of a palladium‐binding peptide to an archaeal rhodopsin promotes intimate integration of the lipid‐embedded membrane protein with a palladium hydride protonic contact.

Summary:Fusion of a palladium‐binding peptide to an archaeal rhodopsin promotes intimate integration of the lipid‐embedded membrane protein with a palladium hydride protonic contact. Devices fabricated with the palladium‐binding deltarhodopsin enable light‐activated conversion of protonic currents to electronic currents with on/off responses complete in seconds and a nearly tenfold increase in electrical signal relative to those made with the wild‐type protein.
