Potential for change: The activity of a fungal laccase on a gold electrode can be modulated by an applied potential. The activity–potential dependence resembles “transistor‐like” current–potential characteristics. The applied potential affects the chemical and electronic structure of the T2/T3 copper cluster of the enzyme by a mechanism similar to that of the natural regulation of laccase activity (see scheme; IET: intramolecular electron transfer).
