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 ...

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.

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 ...

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.

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.

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

A genome-phenome association study in native microbiomes identifies a mechanism for cytosine modification in DNA and RNA

open access: yeseLife, 2021
Shotgun metagenomic sequencing is a powerful approach to study microbiomes in an unbiased manner and of increasing relevance for identifying novel enzymatic functions.
