Abstract
Metal-mediated artificial base pairs are some of the most promising building blocks for constructing DNA-based supramolecules and functional materials. These base pairs are formed by coordination bonds between ligand-type nucleobases and a bridging metal ion and have been exploited to develop metal-responsive DNA materials and DNA-templated metal arrays. In this review, we provide an overview of methods for the enzymatic synthesis of DNA strands containing ligand-type artificial nucleotides that form metal-mediated base pairs. Conventionally, ligand-bearing DNA oligomers have been synthesized via solid-phase synthesis using a DNA synthesizer. In recent years, there has been growing interest in enzymatic methods as an alternative approach to synthesize ligand-bearing DNA oligomers, because enzymatic reactions proceed under mild conditions and do not require protecting groups. DNA polymerases are used to incorporate ligand-bearing unnatural nucleotides into DNA, and DNA ligases are used to connect artificial DNA oligomers to natural DNA fragments. Template-independent polymerases are also utilized to post-synthetically append ligand-bearing nucleotides to DNA oligomers. In addition, enzymatic replication of DNA duplexes containing metal-mediated base pairs has been intensively studied. Enzymatic methods facilitate the synthesis of DNA strands containing ligand-bearing nucleotides at both internal and terminal positions. Enzymatically synthesized ligand-bearing DNAs have been applied to metal-dependent self-assembly of DNA structures and the allosteric control of DNAzyme activity through metal-mediated base pairing. Therefore, the enzymatic synthesis of ligand-bearing oligonucleotides holds great potential in advancing the development of various metal-responsive DNA materials, such as molecular sensors and machines, providing a versatile tool for DNA supramolecular chemistry and nanotechnology.

Abstract
DNA three-way junction (3WJ) structures with three amino acid side chains in the core have been synthesized via post-synthetic DNA modification. Amide condensation reactions of oligonucleotides containing 2'-aminouridine with activated esters yielded DNA strands modified with His, Cys and Asp side chains to form modified 3WJs. Even a 3WJ with three negatively charged Asp side chains formed stably at room temperature. Furthermore, DNA hybridization alone placed two (His and Asp) and three (His, Cys, and Asp) side chains within the 3WJs, indicating that the DNA 3WJs are a useful platform for spatial arrangement of amino acid side chains.

Abstract
A compact 8-17 DNAzyme was modified with a CuII-meditated artificial base pair to develop a metal-responsive allosteric DNAzyme. The base sequence was rationally designed based on the reported three-dimensional structure. The activity of the modified DNAzyme was enhanced 5.1-fold by the addition of one equivalent of CuII ions, showing good metal responsiveness. Since it has been challenging to modify compactly folded DNAzymes without losing their activity, this study demonstrates the utility of the metal-mediated artificial base pairing to create stimuli-responsive functional DNAs.

Abstract
Incorporation of interstrand metal complexes into DNA is a versatile strategy for metal-dependent stabilization and structural induction of DNA supramolecular structures. In this study, we have synthesized DNA three-way junction (3WJ) structures modified with phenanthroline (phen) ligands. The phen-modified 3WJ was found to be thermally stabilized (ΔTm = +16.9 °C) by the formation of an interstrand NiII(phen)3 complex. Furthermore, NiII-mediated structure induction of 3WJs was demonstrated with the phen-modified strands and their unmodified counterparts. This study suggests that ligand-modified 3WJs would be useful structural motifs for the construction of metal-responsive DNA molecular systems.

Abstract
Dynamic control of DNA assembly by external stimuli has received increasing attention in recent years. Dynamic ligand exchange in metal complexes can be a central element in the structural and functional transformation of DNA assemblies. In this study, N,N-dicarboxymethyl-5-aminouracil (dcaU) nucleoside with an iminodiacetic acid (IDA) ligand at the 5-position of the uracil base has been developed as a bifacial nucleoside that can form both hydrogen-bonded and metal-mediated base pairs. Metal complexation study of dcaU nucleosides revealed their ability to form a 2:1 complex with a GdIII ion at the monomeric level. The characteristics of base pairing of dcaU nucleosides were then examined inside DNA duplexes. The results revealed that the formation of the metal-mediated dcaU-GdIII-dcaU pair significantly stabilized the DNA duplex containing one dcaU-dcaU mismatch (ΔT m = +16.1 °C). In contrast, a duplex containing a hydrogen-bonded dcaU-A pair was destabilized in the presence of GdIII (ΔT m = -3.5 °C). The GdIII-dependent base pairing of dcaU bases was applied to control the hybridization preference of DNA in response to metal ions. The hybridization partner of a dcaU-containing strand was reversibly exchanged by the addition and removal of GdIII ions. Since the incorporation of a single dcaU base can switch the hybridization behavior of DNA, the bifacial dcaU base would be a versatile building block for imparting metal responsiveness to DNA assemblies, allowing the rational design of dynamic DNA systems.

Abstract
Metal-mediated nucleobase pairing can play a central role in the expression of metal-responsive DNA functions. We report the CuII-mediated stabilisation of DNA duplexes bearing damaged nucleobases, 1,N6-ethenoadenine (εA), as metal-binding sites, which was utilised to construct a metal-responsive DNAzyme. Consecutive incorporation of three or more εA-εA mismatch pairs allowed for CuII-dependent significant duplex stabilisation through metal-mediated εA-CuII-εA base pairing. Subsequently, a split DNAzyme with three εA-CuII-εA base pairs was strategically designed. The activity of the εA-modified DNAzyme was enhanced by 5.3-fold upon addition of CuII ions. This study demonstrates the utility of εA lesions for building metal-responsive DNA architectures.

Abstract
Artificial metal-mediated DNA base pairing is a promising strategy for creating highly functionalized DNA supramolecules. Here we report a novel ligand-type triazole-4-carboxylate (TazC) nucleoside that is readily prepared by the click reaction. TazC nucleosides were found to form a stable TazC-CuII-TazC base pair inside DNA duplexes, resulting in CuII-specific duplex stabilization (ΔTm = +7.7 °C). This study demonstrates that the triazole derivatives are useful in the development of metal-mediated base pairing.

Abstract
When covalently incorporating ligands capable of forming chiral metal complexes into a DNA oligonucleotide duplex, an enantiospecific formation of metal-mediated base pairs is possible. We have been investigating the chirality of the silver-mediated base pair P-AgI -P (P, 1H-imidazo[4,5-f][1,10]phenanthroline) depending on the number of consecutive P : P pairs within a series of duplexes. Towards this end, both enantiomers of the nucleoside analogue 3-(1H-imidazo[4,5-f][1,10]phenanthrolin-1-yl)propane-1,2-diol comprising an acyclic backbone were introduced into DNA duplexes, resulting in diastereomeric metal-mediated base pairs. The same chiral-at-metal complex is formed inside the duplex for up to five neighbouring P-AgI -P pairs, irrespective of whether (S)-P or (R)-P is used. With six silver-mediated base pairs, the chirality of the metal complex is inverted for (S)-P but not for (R)-P. This indicates an intricate balance of what determines the configuration of the metal complex, the intrinsically preferred metal-centred chirality or the DNA helical chirality.
