Cytosine Methylation: Remaining Faithful [PDF]
Current Biology, 2008 DNA methyltransferase-1 (DNMT1) has a higher specific activity on hemimethylated DNA than on unmethylated DNA, but this preference is too small to explain the faithful mitotic inheritance of genomic methylation patterns. New genetic studies in plants and mammals have identified a novel factor that increases the fidelity of maintenance methylation.

Molecular Cancer, 2020 Background Literature reports that mature microRNA (miRNA) can be methylated at adenosine, guanosine and cytosine. However, the molecular mechanisms involved in cytosine methylation of miRNAs have not yet been fully elucidated.

Consecutive Silver(I) Ion Incorporation into Oligonucleotides containing Cytosine‐Cytosine Mispairs [PDF]
ChemPlusChem, 2020 AbstractInvited for this month's cover is the group of Prof. Heinz‐Bernhard Kraatz from the University of Toronto, Canada. The cover picture shows the consecutive incorporation of AgI ions into a DNA duplex containing adjacent C−C mispairs. Read the full text of the article at 10.1002/cplu.202000607.

Enzymatic approaches for profiling cytosine methylation and hydroxymethylation
Molecular Metabolism, 2022 Background: In mammals, modifications to cytosine bases, particularly in cytosine-guanine (CpG) dinucleotide contexts, play a major role in shaping the epigenome.

Non-Empirically Tuned Range-Separated DFT Accurately Predicts Both Fundamental and Excitation Gaps in DNA and RNA Nucleobases [PDF]
, 2012 Using a non-empirically tuned range-separated DFT approach, we study both the quasiparticle properties (HOMO-LUMO fundamental gaps) and excitation energies of DNA and RNA nucleobases (adenine, thymine, cytosine, guanine, and uracil).

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

Factors Influencing the Nitrogen-Source Dependent Flucytosine Resistance in Cryptococcus Species
mBio, 2023 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 ...
