GrayDiethylaniline-terminated oligo(phenyl-ethynyl)-thiol (DEA-OPE-SH) wires on Au-bead electrodes facilitate electron tunneling to and from the deeply buried topaquinone (TPQ) cofactor in <i>Arthrobacter </i><i>globiformis</i> amine oxidase (AGAO). Reversible cyclic voltammograms were observed when AGAO was adsorbed onto this DEA-OPE-SAu surface: the 2e<sup>-</sup>/2H<sup>+</sup> reduction potential is −140 mV versus SCE.
