Abstract

We propose a fluorescent protein OR gate, which can serve as nanometer-scale building block in photon-coupled, protein-based logic circuits. The structure has numerous advantages with respect to previously introduced photoswitchable protein logic gates, such as its simplicity and faster response time. Furthermore, it can be accomplished with only a single molecule, and fluorescence is the sole requirement, which broadens the choices in contrast to photoswitchable proteins. Besides its operational principle, readily available protein OR gates are introduced, and their integration into photon-coupled protein circuits is discussed, as well. We believe that the present work brings the realization of terahertz-speed molecular circuits yet another step closer.
