Theoretical Study of Cytosine−Al, Cytosine−Cu and Cytosine−Ag (Neutral, Anionic and Cationic)

The Journal of Physical Chemistry A, 2008
The binding of cytosine to Al, Cu and Ag has been analyzed using the hybrid B3LYP density functional theory method. The three metals all have open shell electronic configuration, with only one unpaired valence electron. Thus it is possible to study the influence of electronic configuration on the stability of these systems.

On the mechanism of inhibition of DNA-cytosine methyltransferases by cytosine analogs

Cell, 1983
In recent years 5methylcytosine residues in DNA have been implicated to have an important role in the control of eucaryotic gene expression (see Razin and Riggs, Science 210,604-610,198O). Consequently, there has been much interest in cytosine analogs such as 5azacytosine (5.azaC) and 5-fluorocytosine (5.fluoro-C), which, when incorporated into DNA ...

Cytosine-cytosine+ base pairing stabilizes DNA quadruplexes and cytosine methylation greatly enhances the effect

Biochemistry, 1993
Previous spectroscopic studies demonstrated that the oligodeoxynucleotide d(CGC G3 GCG) undergoes a reversible cation-dependent transition between Watson-Crick (WC) hairpin and parallel-stranded "G-DNA" quadruplex structures [Hardin, C.C., Watson, T., Corregan, M., & Bailey, C. (1992) Biochemistry 31, 833-841].
