[PMID: 39051544 PMCID: PMC11347174 DOI: 10.1093/nar/gkae639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Revised: 07/03/2024] [Accepted: 07/08/2024] [Indexed: 07/27/2024] Open
Abstract
DNA and RNA nucleobase modifications are biologically relevant and valuable in fundamental biochemical and biophysical investigations of nucleic acids. However, directly introducing site-specific nucleobase modifications into long unprotected oligonucleotides is a substantial challenge. In this study, we used in vitro selection to identify DNAzymes that site-specifically N-alkylate the exocyclic nucleobase amines of particular cytidine, guanosine, and adenosine (C, G and A) nucleotides in DNA substrates, by reductive amination using a 5'-benzaldehyde oligonucleotide as the reaction partner. The new DNAzymes each require one or more of Mg2+, Mn2+, and Zn2+ as metal ion cofactors and have kobs from 0.04 to 0.3 h-1, with rate enhancement as high as ∼104 above the splinted background reaction. Several of the new DNAzymes are catalytically active when an RNA substrate is provided in place of DNA. Similarly, several new DNAzymes function when a small-molecule benzaldehyde compound replaces the 5'-benzaldehyde oligonucleotide. These findings expand the scope of DNAzyme catalysis to include nucleobase N-alkylation by reductive amination. Further development of this new class of DNAzymes is anticipated to facilitate practical covalent modification and labeling of DNA and RNA substrates.

Abstract
Xeno nucleic acid (XNA) are artificial nucleic acids, in which the chemical composition of the sugar moiety is changed. These modifications impart distinct physical and chemical properties to XNAs, leading to changes in their biological, chemical, and physical stability. Additionally, these alterations influence the binding dynamics of XNAs to their target molecules. Consequently, XNAs find expanded applications as functional materials in diverse fields. This review provides a comprehensive summary of the distinctive biophysical properties exhibited by various modified XNAs and explores their applications as innovative functional materials in expanded fields.

Abstract
Oligonucleotides are advancing as essential materials for the development of new therapeutics, artificial genes, or in storage of information applications. Hitherto, our capacity to write (i.e., synthesize) oligonucleotides is not as efficient as that to read (i.e., sequencing) DNA/RNA. Alternative, biocatalytic methods for the de novo synthesis of natural or modified oligonucleotides are in dire need to circumvent the limitations of traditional synthetic approaches. This Perspective article summarizes recent progress made in controlled enzymatic synthesis, where temporary blocked nucleotides are incorporated into immobilized primers by polymerases. While robust protocols have been established for DNA, RNA or XNA synthesis is more challenging. Nevertheless, using a suitable combination of protected nucleotides and polymerase has shown promises to produce RNA oligonucleotides even though the production of long DNA/RNA/XNA sequences (>1000 nt) remains challenging. We surmise that merging ligase- and polymerase-based synthesis would help to circumvent the current shortcomings of controlled enzymatic synthesis.

Abstract
To improve their properties or to introduce entirely new functionalities, the intriguing scaffolds of nucleic acids have been decorated with various modifications, most recently also organometallic ones. While challenging to introduce, organometallic modifications offer the potential of expanding the field of application of metal-dependent functionalities to metal-deficient conditions, notably those of biological media. So far, organometallic moieties have been utilized as probes, labels and catalysts. This Feature Article summarizes recent efforts and predicts likely future developments in each of these lines of research.

Abstract
Functional DNAs are valuable molecular tools in chemical biology and analytical chemistry but suffer from low activities due to their limited chemical functionalities. Here, we present a chemoenzymatic method for site-specific installation of diverse functional groups on DNA, and showcase the application of this method to enhance the catalytic activity of a DNA catalyst. Through chemoenzymatic introduction of distinct chemical groups, such as hydroxyl, carboxyl, and benzyl, at specific positions, we achieve significant enhancements in the catalytic activity of the RNA-cleaving deoxyribozyme 10-23. A single carboxyl modification results in a 100-fold increase, while dual modifications (carboxyl and benzyl) yield an approximately 700-fold increase in activity when an RNA cleavage reaction is catalyzed on a DNA-RNA chimeric substrate. The resulting dually modified DNA catalyst, CaBn, exhibits a kobs of 3.76 min-1 in the presence of 1 mM Mg2+ and can be employed for fluorescent imaging of intracellular magnesium ions. Molecular dynamics simulations reveal the superior capability of CaBn to recruit magnesium ions to metal-ion-binding site 2 and adopt a catalytically competent conformation. Our work provides a broadly accessible strategy for DNA functionalization with diverse chemical modifications, and CaBn offers a highly active DNA catalyst with immense potential in chemistry and biotechnology.

Abstract
We used in vitro selection to identify DNAzymes that acylate the exocyclic nucleobase amines of cytidine, guanosine, and adenosine in DNA oligonucleotides. The acyl donor was the 2,3,5,6-tetrafluorophenyl ester (TFPE) of a 5'-carboxyl oligonucleotide. Yields are as high as >95 % in 6 h. Several of the N-acylation DNAzymes are catalytically active with RNA rather than DNA oligonucleotide substrates, and eight of nine DNAzymes for modifying C are site-specific (>95 %) for one particular substrate nucleotide. These findings expand the catalytic ability of DNA to include site-specific N-acylation of oligonucleotide nucleobases. Future efforts will investigate the DNA and RNA substrate sequence generality of DNAzymes for oligonucleotide nucleobase N-acylation, toward a universal approach for site-specific oligonucleotide modification.

Abstract
Chemical modification of aptamers is an important step to improve their performance and stability in biological media. This can be performed either during their identification (mod-SELEX) or after the in vitro selection process (post-SELEX). In order to reduce the complexity and workload of the post-SELEX modification of aptamers, we have evaluated the possibility of improving a previously reported, chemically modified aptamer by combining enzymatic synthesis and nucleotides bearing bioisosteres of the parent cubane side-chains or substituted cubane moieties. This method lowers the synthetic burden often associated with post-SELEX approaches and allowed to identify one additional sequence that maintains binding to the PvLDH target protein, albeit with reduced specificity. In addition, while bioisosteres often improve the potency of small molecule drugs, this does not extend to chemically modified aptamers. Overall, this versatile method can be applied for the post-SELEX modification of other aptamers and functional nucleic acids.

Abstract
Herein, we report the high-yielding solid-phase synthesis of unmodified and chemically modified trinucleotide triphosphates (dN3TPs). These synthetic codons can be used for enzymatic DNA synthesis provided their scaffold is stabilized with phosphorothioate units. Enzymatic synthesis with three rather than one letter nucleotides will be useful to produce xenonucleic acids (XNAs) and for in vitro selection of modified functional nucleic acids.

Abstract
We designed and synthesized a set of four 2'-deoxyribonucleoside 5'-O-triphosphates (dNTPs) derived from 5-substituted pyrimidines and 7-substituted 7-deazapurines bearing anionic substituents (carboxylate, sulfonate, phosphonate, and phosphate). The anion-linked dNTPs were used for enzymatic synthesis of modified and hypermodified DNA using KOD XL DNA polymerase containing one, two, three, or four modified nucleotides. The polymerase was able to synthesize even long sequences of >100 modified nucleotides in a row by primer extension (PEX). We also successfully combined two anionic and two hydrophobic dNTPs bearing phenyl and indole moieties. In PCR, the combinations of one or two modified dNTPs gave exponential amplification, while most of the combinations of three or four modified dNTPs gave only linear amplification in asymmetric PCR. The hypermodified ONs were successfully re-PCRed and sequenced by Sanger sequencing. Biophysical studies including hybridization, denaturation, CD spectroscopy and molecular modelling and dynamics suggest that the presence of anionic modifications in one strand decreases the stability of duplexes while still preserving the B-DNA conformation, whilst the DNA hypermodified in both strands adopts a different secondary structure.

Abstract
Various binding modes of tunable metal organic frameworks (MOFs) and functional DNAzymes (Dzs) synergistically catalyze the emergence of abundant functional nanoplatforms. Given their serial variability in formation, structural designability, and functional controllability, Dzs@MOFs tend to be excellent building blocks for the precise "intelligent" manufacture of functional materials. To present a clear outline of this new field, this review systematically summarizes the progress of Dz integration into MOFs (MOFs@Dzs) through different methods, including various surface infiltration, pore encapsulation, covalent binding, and biomimetic mineralization methods. Atomic-level and time-resolved catalytic mechanisms for biosensing and imaging are made possible by the complex interplay of the distinct molecular structure of Dzs@MOF, conformational flexibility, and dynamic regulation of metal ions. Exploiting the precision of DNAzymes, MOFs@Dzs constructed a combined nanotherapy platform to guide intracellular drug synthesis, photodynamic therapy, catalytic therapy, and immunotherapy to enhance gene therapy in different ways, solving the problems of intracellular delivery inefficiency and insufficient supply of cofactors. MOFs@Dzs nanostructures have become excellent candidates for biosensing, bioimaging, amplification delivery, and targeted cancer gene therapy while emphasizing major advancements and seminal endeavors in the fields of biosensing (nucleic acid, protein, enzyme activity, small molecules, and cancer cells), biological imaging, and targeted cancer gene delivery and gene therapy. Overall, based on the results demonstrated to date, we discuss the challenges that the emerging MOFs@Dzs might encounter in practical future applications and briefly look forward to their bright prospects in other fields.

In this study, we sought DNAzymes as catalytic DNA sequences that promote reductive amination with aliphatic amines, including DNA-anchored peptide substrates with lysine residues. By in vitro selection starting with either N40 or N20 random DNA pools, we identified many DNAzymes that catalyze reductive amination between the DNA oligonucleotide-anchored aliphatic amino group of DNA-C3-NH2 (C3 = short three-carbon tether) and a DNA-anchored benzaldehyde group in the presence of NaCNBH3 as reducing agent. At pH 5.2, 6.0, 7.5, or 9.0 in the presence of various divalent metal ion cofactors including Mg2+, Mn2+, Zn2+ and Ni2+, the DNAzymes have kobs up to 0.12 h-1 and up to 130-fold rate enhancement relative to the DNA-splinted but uncatalyzed background reaction. However, analogous selection experiments did not lead to any DNAzymes that function with DNA-HEG-NH2 [HEG = long hexa(ethylene glycol) tether], or with short- and long-tethered DNA-AAAKAA and DNA-HEG-AAAKAA lysine-containing hexapeptide substrates (A = alanine, K = lysine). Including a variety of other amino acids in place of the neighboring alanines also did not lead to DNAzymes. These findings establish a practical limit on the substrate scope of DNAzyme catalysis for N-alkylation of aliphatic amines by reductive amination. The lack of DNAzymes for reductive amination with any substrate more structurally complex than DNA-C3-NH2 is likely related to the challenge in binding and spatially organizing those other substrates. Because other reactions such as aliphatic amine N-acylation are feasible for DNAzymes with DNA-anchored peptides, our findings show that the ability to identify DNAzymes depends strongly on both the investigated reaction and the composition of the substrate.

Abstract
The unprecedented emergence and spread of SARS-CoV-2, the coronavirus responsible for the COVID-19 pandemic, underscores the need for diagnostic and therapeutic technologies that can be rapidly tailored to novel threats. Here, we show that site-specific RNA endonuclease XNAzymes - artificial catalysts composed of single-stranded synthetic xeno-nucleic acid oligonucleotides (in this case 2'-deoxy-2'-fluoro-β-D-arabino nucleic acid) - may be designed, synthesised and screened within days, enabling the discovery of a range of enzymes targeting SARS-CoV-2 ORF1ab, ORF7b, spike- and nucleocapsid-encoding RNA. Three of these are further engineered to self-assemble into a catalytic nanostructure with enhanced biostability. This XNA nanostructure is capable of cleaving genomic SARS-CoV-2 RNA under physiological conditions, and when transfected into cells inhibits infection with authentic SARS-CoV-2 virus by RNA knockdown. These results demonstrate the potential of XNAzymes to provide a platform for the rapid generation of antiviral reagents.

Abstract
Nucleic-acid catalysts (ribozymes, DNA- and XNAzymes) cleave target (m)RNAs with high specificity but have shown limited efficacy in clinical applications. Here we report on the in vitro evolution and engineering of a highly specific modular RNA endonuclease XNAzyme, FR6_1, composed of 2'-deoxy-2'-fluoro-β-D-arabino nucleic acid (FANA). FR6_1 overcomes the activity limitations of previous DNA- and XNAzymes and can be retargeted to cleave highly structured full-length (>5 kb) BRAF and KRAS mRNAs at physiological Mg2+ concentrations with allelic selectivity for tumour-associated (BRAF V600E and KRAS G12D) mutations. Phosphorothioate-FANA modification enhances FR6_1 biostability and enables rapid KRAS mRNA knockdown in cultured human adenocarcinoma cells with a G12D-allele-specific component provided by in vivo XNAzyme cleavage activity. These results provide a starting point for the development of improved gene-silencing agents based on FANA or other XNA chemistries.

Abstract
Chemically modified oligonucleotides have advanced as important therapeutic tools as reflected by the recent advent of mRNA vaccines and the FDA-approval of various siRNA and antisense oligonucleotides. These sequences are typically accessed by solid-phase synthesis which despite numerous advantages is restricted to short sequences and displays a limited tolerance to functional groups. Controlled enzymatic synthesis is an emerging alternative synthetic methodology that circumvents the limitations of traditional solid-phase synthesis. So far, most approaches strived to improve controlled enzymatic synthesis of canonical DNA and no potential routes to access xenonucleic acids (XNAs) have been reported. In this context, we have investigated the possibility of using phosphate as a transient protecting group for controlled enzymatic synthesis of DNA and locked nucleic acid (LNA) oligonucleotides. Phosphate is ubiquitously employed in natural systems and we demonstrate that this group displays most characteristics required for controlled enzymatic synthesis. We have devised robust synthetic pathways leading to these challenging compounds and we have discovered a hitherto unknown phosphatase activity of various DNA polymerases. These findings open up directions for the design of protected DNA and XNA nucleoside triphosphates for controlled enzymatic synthesis of chemically modified nucleic acids.

Abstract
(2R,3S)-4-(Methoxyamino)butane-1,2,3-triol was converted into a protected phosphoramidite building block and incorporated into the middle of a short DNA oligonucleotide. O1 and O3 of the (2R,3S)-4-(methoxyamino)butane-1,2,3-triol were engaged in phosphodiester linkages, leaving O2 and the methoxyamino function available to form an N-methoxy-1,3-oxazinane ring through reaction with an aldehyde. In modified oligonucleotides thus obtained, the oxazinane ring formally replaces the furanose ring and the aldehyde, the base moiety of natural nucleosides. The feasibility of synthesizing base-modified oligonucleotides by this approach was demonstrated with several aromatic and aliphatic aldehydes featuring various functional groups.

Abstract
Since the first report of DNAzyme by in vitro selection in 1994, catalytic DNA has investigated extensively, and their application has expanded continually in virtue of rapid advances in molecular biology and biotechnology. Nowadays, DNA is in the second prime time by way of DNA-based hybrid catalysts and DNA metalloenzymes in which helical chirality of DNA serves to asymmetric catalysis. DNA-based hybrid catalysts are attractive system to respond the demand of the times to pursuit green and sustainable society beyond traditional catalytic systems that value reaction efficiency. Herein, we highlight the recent advances and perspective of DNA-based hybrid catalysts with various aspects of DNA as a versatile scaffold for asymmetric synthesis. We hope that scientists in a variety of fields will be encouraged to join and promote remarkable evolution of this interesting research.

Abstract
Threose nucleic acid has been considered a potential evolutionary progenitor of RNA because of its chemical simplicity, base pairing properties and capacity for higher-order functions such as folding and specific ligand binding. Here we report the in vitro selection of RNA-cleaving threose nucleic acid enzymes. One such enzyme, Tz1, catalyses a site-specific RNA-cleavage reaction with an observed pseudo first-order rate constant (kobs) of 0.016 min-1. The catalytic activity of Tz1 is maximal at 8 mM Mg2+ and remains relatively constant from pH 5.3 to 9.0. Tz1 preferentially cleaves a mutant epidermal growth factor receptor RNA substrate with a single point substitution, while leaving the wild-type intact. We demonstrate that Tz1 mediates selective gene silencing of the mutant epidermal growth factor receptor in eukaryotic cells. The identification of catalytic threose nucleic acids provides further experimental support for threose nucleic acid as an ancestral genetic and functional material. The demonstration of Tz1 mediating selective knockdown of intracellular RNA suggests that functional threose nucleic acids could be developed for future biomedical applications.

Abstract
Threose nucleic acid (TNA) has been considered a potential RNA progenitor in evolution due to its chemical simplicity and base pairing property. Catalytic TNA sequences with RNA ligase activities might have facilitated the transition to the RNA world. Here we report the isolation of RNA ligase TNA enzymes by in vitro selection. The identified TNA enzyme T8-6 catalyzes the formation of a 2'-5' phosphoester bond between a 2',3'-diol and a 5'-triphosphate group, with a kobs of 1.1 × 10-2 min-1 (40 mM Mg2+, pH 9.0). For efficient reaction, T8-6 requires UA|GA at the ligation junction and tolerates variations at other substrate positions. Functional RNAs such as hammerhead ribozyme can be prepared by T8-6-catalyzed ligation, with site-specific introduction of a 2'-5' linkage. Together, this work provides experimental support for TNA as a plausible pre-RNA genetic polymer and also offers an alternative molecular tool for biotechnology.

Abstract
Artificial metal base pairs have become increasingly important in nucleic acids chemistry due to their high thermal stability, water solubility, orthogonality to natural base pairs, and low cost of production. These interesting properties combined with ease of chemical and enzymatic synthesis have prompted their use in several practical applications, including the construction of nanomolecular devices, ions sensors, and metal nanowires. Chemical synthesis of metal base pairs is highly efficient and enables the rapid screening of novel metal base pair candidates. However, chemical synthesis is limited to rather short oligonucleotides and requires rather important synthetic efforts. Herein, we discuss recent progress made for the enzymatic construction of metal base pairs that can alleviate some of these limitations. First, we highlight the possibility of generating metal base pairs using canonical nucleotides and then describe how modified nucleotides can be used in this context. We also provide a description of the main analytical techniques used for the analysis of the nature and the formation of metal base pairs together with relevant examples of their applications.

Abstract
The construction of a host-orthogonal genetic system can not only minimize the impact of host-specific nuances on fine-tuning of gene expression, but also expand cellular functions such as in vivo continuous evolution of genes based on an error-prone DNA polymerase. It represents an emerging powerful approach for making biology easier to engineer. In this review, the recent advances are described on the design of genetic systems that can be stably inherited in the host cells and are responsible for important biological processes including DNA replication, RNA transcription, protein translation, and gene regulation. Their applications in synthetic biology are summarized and the future challenges and opportunities are discussed in developing such systems.

Abstract
Although several DNAzymes are known, their utility is limited by a narrow range of substrate specificity. Here, we report the isolation of two zinc-dependent DNAzymes, ZincDz1 and ZincDz2, which exhibit compact catalytic core sequences with highly versatile hydrolysis activity. They were selected through in vitro selection followed by deep sequencing analysis. Despite their sequence similarity, each DNAzyme showed different Zn2+-concentration and pH-dependent reaction profiles, and cleaved the target RNA sequences at different sites. Using various substrate RNA sequences, we found that the cleavage sequence specificity of ZincDz2 and its highly active mutant ZincDz2-v2 to be 5'-rN↓rNrPu-3'. Furthermore, we demonstrated that the designed ZincDz2 could cut microRNA miR-155 at three different sites. These DNAzymes could be useful in a broad range of applications in the fields of medicine and biotechnology.

Abstract
Guanine quadruplex nucleic acids (G4s) are involved in key biological processes such as replication or transcription. Beyond their biological relevance, G4s find applications as biotechnological tools since they readily bind hemin and enhance its peroxidase activity, creating a G4-DNAzyme. The biocatalytic properties of G4-DNAzymes have been thoroughly studied and used for biosensing purposes. Despite hundreds of applications and massive experimental efforts, the atomistic details of the reaction mechanism remain unclear. To help select between the different hypotheses currently under investigation, we use extended explicit-solvent molecular dynamics (MD) simulations to scrutinize the G4/hemin interaction. We find that besides the dominant conformation in which hemin is stacked atop the external G-quartets, hemin can also transiently bind to the loops and be brought to the external G-quartets through diverse delivery mechanisms. The simulations do not support the catalytic mechanism relying on a wobbling guanine. Similarly, the catalytic role of the iron-bound water molecule is not in line with our results; however, given the simulation limitations, this observation should be considered with some caution. The simulations rather suggest tentative mechanisms in which the external G-quartet itself could be responsible for the unique H2O2-promoted biocatalytic properties of the G4/hemin complexes. Once stacked atop a terminal G-quartet, hemin rotates about its vertical axis while readily sampling shifted geometries where the iron transiently contacts oxygen atoms of the adjacent G-quartet. This dynamics is not apparent from the ensemble-averaged structure. We also visualize transient interactions between the stacked hemin and the G4 loops. Finally, we investigated interactions between hemin and on-pathway folding intermediates of the parallel-stranded G4 fold. The simulations suggest that hemin drives the folding of parallel-stranded G4s from slip-stranded intermediates, acting as a G4 chaperone. Limitations of the MD technique are briefly discussed.

Abstract
DNAzymes were previously identified by in vitro selection for a variety of chemical reactions, including several biologically relevant peptide modifications. However, finding DNAzymes for peptide lysine acylation is a substantial challenge. By using suitably reactive aryl ester acyl donors as the electrophiles, here we used in vitro selection to identify DNAzymes that acylate amines, including lysine side chains of DNA-anchored peptides. Some of the DNAzymes can transfer a small glutaryl group to an amino group. These results expand the scope of DNAzyme catalysis and suggest the future broader applicability of DNAzymes for sequence-selective lysine acylation of peptide and protein substrates.

Abstract
Synthetic nucleic acids, with four non-canonical nucleobases, can function as genetic materials. A comprehensive analysis of PCR amplification, transcription, reverse transcription, and cloning was done to screen for alternative genetic monomers. A small library of six modified nucleobases was selected: the modified 2'-deoxyribonucleoside (dZTPs) and ribonucleoside (rZTPs) triphosphates of 7-deaza-adenine, 5-chlorouracil, 7-deaza-guanine or inosine together with 5-fluorocytosine or 5-bromocytosine. The fragments composed of one to four modified nucleotides (denoted as DZA) have been successfully recognized and transcribed to natural or modified RNA (denoted as RZA) by T7 RNA polymerase. The fully modified RZA fragment could be reverse transcribed and then amplified in the presence of various dZTPs. Noticeably, modified fragments could function as genetic templates in vivo by encoding the 678 base pair gene of a fluorescent protein in bacteria. These results demonstrate the existence of a fully simulated genetic circuit that uses synthetic materials.

Abstract
In the last three decades, oligonucleotides have been extensively investigated as probes, molecular ligands and even catalysts within therapeutic and diagnostic applications. The narrow chemical repertoire of natural nucleic acids, however, imposes restrictions on the functional scope of oligonucleotides. Initial efforts to overcome this deficiency in chemical diversity included conservative modifications to the sugar-phosphate backbone or the pendant base groups and resulted in enhanced in vivo performance. More importantly, later work involving other modifications led to the realization of new functional characteristics beyond initial intended therapeutic and diagnostic prospects. These results have inspired the exploration of increasingly exotic chemistries highly divergent from the canonical nucleic acid chemical structure that possess unnatural physiochemical properties. In this review, the authors highlight recent developments in modified oligonucleotides and the thrust towards designing novel nucleic acid-based ligands and catalysts with specifically engineered functions inaccessible to natural oligonucleotides.

Abstract
An oxidative DNA-cleaving DNAzyme (PL) employs a double-cofactor model “X/Cu2+” for catalysis. Herein, we verified that reduced nicotinamide adenine dinucleotide (NADH), flavin mononucleotide, cysteine, dithiothreitol, catechol, resorcinol, hydroquinone, phloroglucinol, o-phenylenediamine, 3,3′,5,5'-tetramethylbenzidine, and hydroxylamine acted as cofactor X. According to their structural similarities or fluorescence property, we further confirmed that reduced nicotinamide adenine dinucleotide phosphate (NADPH), 2-mercaptoethanol, dopamine, chlorogenic acid, resveratrol, and 5-carboxyfluorescein also functioned as cofactor X. Superoxide anions might be the commonality behind these cofactors. We subsequently determined the conservative change of individual nucleotides in the catalytic core under four different cofactor X. The nucleotides A4 and C5 are highly conserved, whereas the conservative levels of other nucleotides are dependent on the types of cofactor X. Moreover, we observed that the minor change in the PL's secondary structure affects electrophoretic mobility. Finally, we characterized a highly efficient variant T3G and converted its double-cofactor NADH/Cu2+ to sole-cofactor NADH. An oxidative cleavage DNAzyme works with various cofactor X Catalytic nucleotide conservation fluctuates with different cofactor X The PL DNAzyme's minor secondary structure change affects electrophoretic mobility Double-cofactor model of the variant T3G can be converted to sole-cofactor model

Abstract
While many protein enzymes exert their functions through multimerization, which improves both selectivity and activity, this has not yet been demonstrated for other naturally occurring catalysts. Here, we report a multimerization effect applied to catalytic DNAs (or DNAzymes) and demonstrate that the enzymatic efficiency of G-quadruplexes (GQs) in interaction with the hemin cofactor is remarkably enhanced by homodimerization. The resulting non-covalent dimeric GQ-DNAzyme system provides hemin with a structurally defined active site in which both the cofactor (hemin) and the oxidant (H2O2) are activated. This new biocatalytic system efficiently performs peroxidase- and peroxygenase-type biotransformations of a broad range of substrates, thus providing new perspectives for biotechnological application of GQs.

Abstract
Aptamers are short single stranded DNA or RNA oligonucleotides that can recognize analytes with extraordinary target selectivity and affinity. Despite their promising properties and diagnostic potential, the number of commercial applications remains scarce. In order to endow them with novel recognition motifs and enhanced properties, chemical modification of aptamers has been pursued. This review focuses on chemical modifications, aimed at increasing the binding affinity for the aptamer's target either in a non-covalent or covalent fashion, hereby improving their application potential in a diagnostic context. An overview of current methodologies will be given, thereby distinguishing between pre- and post-SELEX (Systematic Evolution of Ligands by Exponential Enrichment) modifications.

Abstract
The incorporation of nucleotides equipped with C-glycosidic aromatic nucleobases into DNA and RNA is an alluring strategy for a number of practical applications including fluorescent labelling of oligonucleotides, expansion of the genetic alphabet for the generation of aptamers and semi-synthetic organisms, or the modulation of excess electron transfer within DNA. However, the generation of C-nucleoside containing oligonucleotides relies mainly on solid-phase synthesis which is quite labor intensive and restricted to short sequences. Here, we explore the possibility of constructing biphenyl-modified DNA sequences using enzymatic synthesis. The presence of multiple biphenyl-units or biphenyl residues modified with electron donors and acceptors permits the incorporation of a single dBphMP nucleotide. Moreover, templates with multiple abasic sites enable the incorporation of up to two dBphMP nucleotides, while TdT-mediated tailing reactions produce single-stranded DNA oligonucleotides with four biphenyl residues appended at the 3'-end.

Abstract
In this work, a hydrazone chemistry assisted DNAzyme has been designed and constructed. The introduction of hydrazone chemistry increases the versatility of DNAzymes. With superior catalytic capability, the hydrazone chemistry assisted DNAzyme has been successfully applied for the analysis of double targets. Taking 5-hydroxymethylfurfural (HMF) and lipopolysaccharide (LPS) as samples, the hydrazone chemistry assisted DNAzyme can be used for the detection of different combinations of targets. Moreover, because hydrazone chemistry is popular in nature, this work may also provide a new insight for the development of DNAzymes and their multifunctionality.

Abstract
8-17 and 17E DNAzyme are being explored as biosensors for metal ions and RNA motifs of interest, more sensitive and efficient DNAzymes are required to meet the practical applications. Their similarity in the catalytic cores and differences in catalytic efficiency and metal ion dependence initiated great interest about the contribution of the catalytic residues. Functionalization of four adenine residues in the catalytic cores of 8-17 DNAzyme and 17E was conducted with amino, guanidinium, and imidazolyl groups. In the bulge loops of 8-17 and 17E, N6-(3-aminopropyl)-2'-deoxyadenosine (residue 1) at A15 led to new DNAzymes 8-17DZ-A15-1 and 17E-A15-1, with much more efficient cleavage ability in the Ca2+-mediated reaction and the greater preference for Ca2+ over Mg2+ than 8-17 DNAzyme and 17E, respectively, especially with a concentration-dependent increase of the selectivity, which is different from most DNAzymes with the similar dependence on both Mg2+ and Ca2+. With this kind of post-selection modification on 8-17 DNAzymes, for the first time, the catalytic efficiency and metal ion selectivity could be positively modulated. It is also helpful for the catalyic mechanistic studies of these DNAzymes, especially, the role of the unconserved A15 should be emphasized.

Abstract
The formation of artificial metal base pairs is an alluring and versatile method for the functionalization of nucleic acids. Access to DNA functionalized with metal base pairs is granted mainly by solid-phase synthesis. An alternative, yet underexplored method, envisions the installation of metal base pairs through the polymerization of modified nucleoside triphosphates. Herein, we have explored the possibility of using thiolated and pKa -perturbed nucleotides for the enzymatic construction of artificial metal base pairs. The thiolated nucleotides S2C, S6G, and S4T as well as the fluorinated analogue 5FU are readily incorporated opposite a templating S4T nucleotide through the guidance of metal cations. Multiple incorporation of the modified nucleotides along with polymerase bypass of the unnatural base pairs are also possible under certain conditions. The thiolated nucleotides S4T, S4T, S2C, and S6G were also shown to be compatible with the synthesis of modified, high molecular weight single-stranded (ss)DNA products through TdT-mediated tailing reactions. Thus, sulfur-substitution and pKa perturbation represent alternative strategies for the design of modified nucleotides compatible with the enzymatic construction of metal base pairs.

Abstract
A modified nucleoside triphosphate bearing two modifications based on a 2'-deoxy-2'-fluoro-arabinofuranose sugar and a uracil nucleobase equipped with a C5-ethynyl moiety (5-ethynyl-2'F-ANA UTP) was synthesized. This nucleotide analog could enzymatically be incorporated into DNA oligonucleotides by primer extension and reverse transcribed to unmodified DNA. This nucleotide could be used in SELEX for the identification of high binding affinity and nuclease resistant aptamers.
