Enzyme transistor circuits for biomolecular computing

Abstract

A model of an enzyme transistor, a three-terminal biomolecular switching device, is proposed. Ideally, an enzyme transistor can be regarded as an artificial enzyme whose catalytic activity is controlled by some effector molecule. In this paper, we show that various biomolecular circuits can be constructed with enzyme transistors. Also, a possible approach to the implementation based on electrical control of enzyme reactions is discussed.
