DNA Labeling Using DNA Methyltransferases

2016
DNA methyltransferases (MTases) uniquely combine the ability to recognize and covalently modify specific target sequences in DNA using the ubiquitous cofactor S-adenosyl-L-methionine (AdoMet). Although DNA methylation plays important roles in biological signaling, the transferred methyl group is a poor reporter and is highly inert to further ...

Targeting duplex DNA with DNA‐PNA chimeras? Physico‐chemical characterization of a triplex DNA‐PNA/DNA/DNA

Biopolymers, 2004
AbstractTargeting double‐stranded DNA with homopyrimidine PNAs results in strand displacement complexes PNA/DNA/PNA rather than PNA/DNA/DNA triplex structures. Not much is known about the binding properties of DNA‐PNA chimeras. A 16‐mer 5′‐DNA‐3′‐p‐(N)PNA(C) has been investigated for its ability to hybridize a complementary duplex DNA by DSC, CD, and ...

DNA Methyltransferases and DNA Damage

2022
Ever since the discovery of depletion of CG sites in mammalian genomes it has been clear that cytosine DNA methyltransferases (DNMTs) are linked to the rate at which mutations accumulate in DNA. Research in the intervening decades has shown that DNMTs influence mutation rates through the indirect consequences of methylation on the mechanism of mutation

DNA-PEG-DNA Triblock Macromolecules for Reagentless DNA Detection

Journal of the American Chemical Society, 2004
The sandwich assay is the most common design for electrochemical DNA sensors. This assay consists of three individual DNA components: an immobilized capture strand, a target strand, and a probe strand containing a redox-active reporter group. We report a simplified DNA assay where two strands of ssDNA, the capture and probe strands, are linked together

DNA NANOTECHNOLOGY: Novel DNA Constructions

Annual Review of Biophysics and Biomolecular Structure, 1998
▪ Abstract  DNA nanotechnology entails the construction of specific geometrical and topological targets from DNA. The goals include the use of DNA molecules to scaffold the assembly of other molecules, particularly in periodic arrays, with the objects of both crystal facilitation and memory-device construction.

DNA Glycosylases in DNA Repair

1986
The excision of potentially mutagenic and lethal lesions from DNA proceeds by one of two different routes. DNA damage which results in a major distortion of the DNA double-helix is generally recognized by a high-molecular weight nuclease that cuts two phosphodiester bonds in the altered strand, one on each side of the lesion.

Eukaryotic DNA polymerases in DNA replication and DNA repair

Chromosoma, 1998
DNA polymerases carry out a large variety of synthetic transactions during DNA replication, DNA recombination and DNA repair. Substrates for DNA polymerases vary from single nucleotide gaps to kilobase size gaps and from relatively simple gapped structures to complex replication forks in which two strands need to be replicated simultaneously ...
