Nucleic acid templated reactions have attracted attention as an important technology to sense oligonucleotides and to translate nucleic acid-based instructions into diverse outputs. Great progresses have been made in accelerating the reaction in order to improve signal amplification, reaching rates where substrate turn-over rather than chemical reaction is rate limiting. Herein we explore the utility of architectures inspired by three-way junction that yield a cleavage of a strand thus accelerating substrate turn-over. We demonstrate that such design can overcome product inhibition in templated reactions and operate close to the rate of hybridization.
