MeDReaders 2.0: an updated database for modified DNA readers [PDF]

open access: yesBMC Genomics
Here, we present a significant update to the MeDReaders database and webserver. The new MeDReaders 2.0 covers interactions between transcription factors (TFs) and DNA cytosine modifications that arise during DNA methylation and active demethylation ...

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 ...

Structure of mouse DNA (cytosine-5-)-methyltransferase [PDF]

open access: yesEuropean Journal of Biochemistry, 1988
DNA (cytosine‐5‐)‐methyltransferase was purified as a single polypeptide (190 kDa by SDS‐PAGE) from mouse P815 mastocytoma cells. This enzyme transfers methyl groups to unmethylated as well as to hemimethylated DNA sites with a strong preference for the hemimethylated substrate.

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.

A mutant of uracil DNA glycosylase that distinguishes between cytosine and 5-methylcytosine. [PDF]

open access: yesPLoS ONE, 2014
We demonstrate that a mutant of uracil DNA glycosylase (N123D:L191A) distinguishes between cytosine and methylcytosine. Uracil DNA glycosylase (UDG) efficiently removes uracil from DNA in a reaction in which the base is flipped into the enzyme's active ...

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.

In silico structural analysis of sequences containing 5-hydroxymethylcytosine reveals its potential as binding regulator for development, ageing and cancer-related transcription factors

open access: yesEpigenetics, 2021
The presence of 5-hydroxymethyl cytosine in DNA has been previously associated with ageing. Using in silico analysis of normal liver samples we presently observed that in 5-hydroxymethyl cytosine sequences, DNA methylation is dependent on the co-presence

Acceleration of the Deamination of Cytosine through Photo-Crosslinking

open access: yesCurrent Issues in Molecular Biology, 2023
Herein, we report the major factor for deamination reaction rate acceleration, i.e., hydrophilicity, by using various 5-substituted target cytosines and by carrying out deamination at high temperatures.

An orphan DNA (cytosine-5-)-methyltransferase in Vibrio cholerae [PDF]

open access: yesMicrobiology, 2006
5-Methyl cytosine (m5C) was detected in genomic DNA of the enteric pathogen Vibrio cholerae by HPLC analysis and immunoblotting with m5C-specific antibody. Although cleavage with the restriction endonuclease EcoRII revealed the absence of a Dcm homologue in V.
