Abstract
In biology, nanomachines like the ribosome use nucleic acid templates to synthesize polymers in a sequence-specific, programmable fashion. Researchers have long been interested in using the programmable properties of nucleic acids to enhance chemical reactions via colocalization of reagents using complementary nucleic acid handles. In this review, we describe progress in using nucleic acid templates, handles, or splints to enhance the covalent coupling of peptides to other peptides or oligonucleotides. We discuss work in several areas: creating ribosome-mimetic systems, synthesizing bioactive peptides on DNA or RNA templates, linking peptides into longer molecules and bioactive antibody mimics, and scaffolding peptides to build protein-mimetic architectures. We close by highlighting the challenges that must be overcome in nucleic acid-templated peptide chemistry in two areas: making full-length, functional proteins from synthetic peptides and creating novel protein-mimetic architectures not possible through macromolecular folding alone.

Abstract
The design of new protein structures is challenging due to their vast sequence space and the complexity of protein folding. Here, we report a new modular DNA-templated strategy to construct protein mimics. We achieve the spatial control of multiple peptide units by conjugation with DNA and hybridization to a branched DNA trimer template followed by covalent stapling of the preorganized peptides into a single unit. A library of protein mimics with different lengths, sequences, and heptad registers has been efficiently constructed. DNA-templated protein mimics show an α-helix or coiled-coil motif formation even when they are constructed from weakly interacting peptide units. Their attached DNA handles can be used to exert dynamic control over the protein mimics' secondary and tertiary structures. This modular strategy will facilitate the development of DNA-encoded protein libraries for the rapid discovery of new therapeutics, enzymes, and antibody mimics.

Abstract
DNA-stabilized silver nanoclusters (DNA-AgNCs) are biocompatible emitters with intriguing properties. However, they have not been extensively used for bioimaging applications due to the lack of structural information and hence predictable conjugation strategies. Here, a copper-free click chemistry method for linking a well-characterized DNA-AgNC to molecules of interest is presented. Three different peptides and a small protein, human insulin, were tested as labeling targets. The conjugation to the target compounds was verified by MS, HPLC, and time-resolved anisotropy measurements. Moreover, the spectroscopic properties of DNA-AgNCs were found to be unaffected by the linking reactions. For DNA-AgNC-conjugated human insulin, fluorescence imaging studies were performed on Chinese hamster ovary (CHO) cells overexpressing human insulin receptor B (hIR-B). The specific staining of the CHO cell membranes demonstrates that DNA-AgNCs are great candidates for bioimaging applications, and the proposed linking strategy is easy to implement when the DNA-AgNC structure is known.

Abstract
Nucleic acids and proteins form two of the key classes of functional biomolecules. Through the ability to access specific protein-oligonucleotide conjugates, a broader range of functional molecules becomes accessible which leverages both the programmability and recognition potential of nucleic acids and the structural, chemical and functional diversity of proteins. Herein, we summarize the available conjugation strategies to access such chimeric molecules and highlight some key case study examples within the field to showcase the power and utility of such technology.

Abstract
Chiral communications exist in secondary structures of foldamers and copolymers via a network of noncovalent interactions within effective intermolecular force (IMF) range. It is not known whether long-range chiral communication exists between macromolecular tertiary structures such as peptide coiled-coils beyond the IMF distance. Harnessing the high sensitivity of single-molecule force spectroscopy, we investigate the chiral interaction between covalently linked DNA duplexes and peptide coiled-coils by evaluating the binding of a diastereomeric pair of three DNA-peptide conjugates. We find that right-handed DNA triple helices well accommodate peptide triple coiled-coils of the same handedness, but not with the left-handed coiled-coil stereoisomers. This chiral communication is effective in a range (<4.5 nm) far beyond canonical IMF distance. Small-angle X-ray scattering and molecular dynamics simulation indicate that the interdomain linkers are tightly packed via hydrophobic interactions, which likely sustains the chirality transmission between DNA and peptide domains. Our findings establish that long-range chiral transmission occurs in tertiary macromolecular domains, explaining the presence of homochiral pairing of superhelices in proteins. Chiral communication can propagate in secondary structures within the effective intermolecular force (IMF) range but it is not known whether long-range chiral communication exists between tertiary peptide structures. Here, the authors use single-molecule force spectroscopy to investigate chiral interaction between DNA duplexes/triplexes and peptide coiled-coils and demonstrate chiral communication beyond the IMF distance.
