The DNA (cytosine-5) methyltransferases [PDF]

open access: yesNucleic Acids Research, 1994
The m5C-MTases form a closely-knit family of enzymes in which common amino acid sequence motifs almost certainly translate into common structural and functional elements. These common elements are located predominantly in a single structural domain that performs the chemistry of the reaction.

DNA bending induced by DNA (cytosine-5) methyltransferases. [PDF]

open access: yesNucleic Acids Research, 2000
DNA bending induced by six DNA (cytosine-5) methyltransferases was studied using circular permutation gel mobility shift assay. The following bend angles were obtained: M.BSP:RI (GG(m5)CC), 46-50 degrees; M.HAE:III (GG(m5)CC), 40-43 degrees; M.SIN:I (GGW(m5)CC), 34-37 degrees; M.SAU:96I (GGN(m5)CC), 52-57 degrees; M.HPA:II (C(m5)CGG), 30 degrees; and M.

Enzymatic properties of de novo-type mouse DNA (cytosine-5) methyltransferases. [PDF]

open access: yesNucleic Acids Research, 2001
We have purified GST-fused recombinant mouse Dnmt3a and three isoforms of mouse Dnmt3b to near homogeneity. Dnmt3b3, an isoform of Dnmt3b, did not have DNA methylation activity. Dnmt3a, Dnmt3b1 or Dnmt3b2 showed similar activity toward poly(dG-dC)-poly(dG-dC) for measuring de novo methylation activity, and toward poly(dI-dC)-poly(dI-dC) for measuring ...

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.

Molecular Cloning, Expression, and Characterization of Starfish DNA (Cytosine-5)-methyltransferases

open access: yesBioscience, Biotechnology, and Biochemistry, 2012
To determine whether and if so how a DNA methylation-dependent epigenetic mechanism for transcriptional gene silencing functions in Echinoderms, we cloned and sequenced dnmt1 and dnmt3 cDNAs of the starfish Asterina pectinifera. Since the Strongylocentrotus purpuratus genome has only two loci of DNA (cytosine-5)-methyltransferase genes encoding Dnmt1 ...

Plant cytosine-5 DNA methyltransferases: structure, function, and molecular evolution.

open access: yesGenomics, 2007
A detailed analysis of the structure and function, along with evolutionary aspects, of the main plant cytosine-5 DNA methyltransferases (C5-MTases) is presented. The evolutionary relationships between the already known and four candidate plant C5-MTases identified in this work were investigated using the distance, maximum-parsimony, and maximum ...

Diverse Domains of (Cytosine-5)-DNA Methyltransferases: Structural and Functional Characterization [PDF]

open access: yes, 2012
(Cytosine-5)-DNA methyltransferases (C5-DNA MTases) are enzymes which catalyze meth‐ yl group transfer from S-adenosyl-L-methionine (AdoMet) to C5 atom of cytosine residue in DNA.

The Impact of the HydroxyMethylCytosine epigenetic signature on DNA structure and function

open access: yesPLoS Computational Biology, 2021
We present a comprehensive, experimental and theoretical study of the impact of 5-hydroxymethylation of DNA cytosine. Using molecular dynamics, biophysical experiments and NMR spectroscopy, we found that Ten-Eleven translocation (TET) dioxygenases ...

Identification, expression, and purification of DNA cytosine 5-methyltransferases with short recognition sequences

open access: yesbioRxiv, 2022
Background DNA methyltransferases (MTases) are enzymes that induce methylation, one of the representative epigenetic modifications of DNA, and are also useful tools for analyzing epigenomes.

The behaviour of 5-hydroxymethylcytosine in bisulfite sequencing. [PDF]

open access: yesPLoS ONE, 2010
We recently showed that enzymes of the TET family convert 5-mC to 5-hydroxymethylcytosine (5-hmC) in DNA. 5-hmC is present at high levels in embryonic stem cells and Purkinje neurons.
