Designed RNAs with two peptide-binding units as artificial templates for native chemical ligation of RNA-binding peptides.

Abstract excerpt

The template effect plays important roles not only in modern synthetic and enzymatic catalysis but also in the ancient "RNA-polypeptide (RNP) world," which has been postulated to be a crucial stage in the origin of life. To mimic primitive template catalysis of peptide ligations by RNAs, we previously reported the design and synthesis of a ternary RNP complex in which the ligation of two peptides was...
