Epigenetics of Modified DNA Bases: 5-Methylcytosine and Beyond

open access: yesFrontiers in Genetics, 2018
Modification of DNA bases plays vital roles in the epigenetic control of gene expression in both animals and plants. Though much attention is given to the conventional epigenetic signature 5-methylcytosine (5-mC), the field of epigenetics is attracting ...

Engineering the DNA cytosine-5 methyltransferase reaction for sequence-specific labeling of DNA [PDF]

open access: yesNucleic Acids Research, 2012
DNA methyltransferases catalyse the transfer of a methyl group from the ubiquitous cofactor S-adenosyl-L-methionine (AdoMet) onto specific target sites on DNA and play important roles in organisms from bacteria to humans. AdoMet analogs with extended propargylic side chains have been chemically produced for methyltransferase-directed transfer of ...

Fluorescent Method for the Detection of Biothiols Using an Ag+-Mediated Conformational Switch

open access: yesSensors, 2019
In this work, a novel, simple, and time-saving fluorescence approach for the detection of biothiols (glutathione and cysteine) was developed by employing a DNA probe labeled with 2-aminopurine.

Chemical display of pyrimidine bases flipped out by modification-dependent restriction endonucleases of MspJI and PvuRts1I families.

open access: yesPLoS ONE, 2014
The epigenetic DNA modifications 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) in eukaryotes are recognized either in the context of double-stranded DNA (e.g., by the methyl-CpG binding domain of MeCP2), or in the flipped-out state (e.g., by ...

Molecular Dynamics Simulation of Melting of the DNA Duplex with Silver-Mediated Cytosine–Cytosine Base Pair

open access: yesComputation
Metal-mediated base pairs in DNA double helix molecules open up broad opportunities for biosensors based on DNA clusters with silver due to their low toxicity and applicability in drug design.

Discovery of Bacterial Deaminases That Convert 5-Fluoroisocytosine Into 5-Fluorouracil

open access: yesFrontiers in Microbiology, 2018
Cytosine is one of the four letters of a standard genetic code, found both in DNA and in RNA. This heterocyclic base can be converted into uracil upon the action of the well-known cytosine deaminase.

The DNA cytosine methylome revealed two methylation motifs in the upstream regions of genes related to morphological and physiological differentiation in Streptomyces coelicolor A(3)2 M145

open access: yesScientific Reports, 2023
DNA methylation is an epigenetic modification detected in both prokaryotic and eukaryotic genomic DNAs. In bacteria, the importance of 5-methylcytosine (m5C) in gene expression has been less investigated than in eukaryotic systems.

rahu is a mutant allele of Dnmt3c, encoding a DNA methyltransferase homolog required for meiosis and transposon repression in the mouse male germline. [PDF]

open access: yesPLoS Genetics, 2017
Transcriptional silencing by heritable cytosine-5 methylation is an ancient strategy to repress transposable elements. It was previously thought that mammals possess four DNA methyltransferase paralogs-Dnmt1, Dnmt3a, Dnmt3b and Dnmt3l-that establish and ...
