In this research, we have design an ATP binding domain that consists of an RNA subunit and a peptide subunit by means of structure-based design approach and in vitro selection method. The RNA subunit is designed to consist of two functional domains; an ATP binding domain with 20 randomized nucleotides and an adjacent stem region that serves as a binding site for the RNA-binding peptide. RNA-peptide receptors to ATP were isolated from a pool of different RNAs by selection with affinity column and enzymatic amplification. Effects of the RNA-binding peptide for the specific ATP binding to the selected RNA-peptide receptors are discussed.
