Synergistic DNA‐ and Protein‐Based Recognition Promote an RNA‐Templated Bio‐orthogonal Reaction
Biomolecular assemblies composed of proteins and oligonucleotides play a central role in biological processes. While in nature, oligonucleotides and proteins usually assemble via non‐covalent interactions, synthetic conjugates have been developed which covalently link both modalities. The resulting...

description | Biomolecular assemblies composed of proteins and oligonucleotides play a central role in biological processes. While in nature, oligonucleotides and proteins usually assemble via non‐covalent interactions, synthetic conjugates have been developed which covalently link both modalities. The resulting peptide‐oligonucleotide conjugates have facilitated novel biological applications as well as the design of functional supramolecular systems and materials. However, despite the importance of concerted protein/oligonucleotide recognition in nature, conjugation approaches have barely utilized the synergistic recognition abilities of such complexes. Herein, the structure‐based design of peptide‐DNA conjugates that bind RNA through Watson‐Crick base pairing combined with peptide‐mediated major groove recognition is reported. Two distinct conjugate families with tunable binding characteristics have been designed to adjacently bind a particular RNA sequence. In the resulting ternary complex, their peptide elements are located in proximity, a feature that was used to enable an RNA‐templated click reaction. The introduced structure‐based design approach opens the door to novel functional biomolecular assemblies. |
