DNA methyltransferase 1, cytosine methylation, and cytosine hydroxymethylation in mammalian mitochondria [PDF]
Mitochondrial DNA (mtDNA) has been reported to contain 5-methylcytosine (5mC) at CpG dinucleotides, as in the nuclear genome, but neither the mechanism generating mtDNA methylation nor its functional significance is known. We now report the presence of 5-hydroxymethylcytosine (5hmC) as well as 5mC in mammalian mtDNA, suggesting that previous studies ...

Enzymatic approaches for profiling cytosine methylation and hydroxymethylation
Background: In mammals, modifications to cytosine bases, particularly in cytosine-guanine (CpG) dinucleotide contexts, play a major role in shaping the epigenome.

Structural basis for DNMT3A-mediated de novo DNA methylation. [PDF]
DNA methylation by de novo DNA methyltransferases 3A (DNMT3A) and 3B (DNMT3B) at cytosines is essential for genome regulation and development. Dysregulation of this process is implicated in various diseases, notably cancer.

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

Factors Influencing the Nitrogen-Source Dependent Flucytosine Resistance in Cryptococcus Species
Flucytosine (5-FC) is an antifungal agent commonly used for treatment of cryptococcosis and several other systemic mycoses. In fungi, cytosine permease and cytosine deaminase are known major players in flucytosine resistance by regulating uptake and ...
