Flipping Back of Extrahelical Guanine after Methyl Repair
Methylation at O6 atom of guanine is a type of DNA damage which can cause a cancer. This damage at O6 atom of guanine in a DNA can be transferred to SG atom of cysteine in O6-alkylguanine-DNA alkyltransferase (AGT).

A new possible way for cancer cure – DNA four strand [PDF]
DNA is the active ingredient of all the biological operations of the cell because it stores genetic information in the configuration of genes. It is a very well recognized fact that DNA has a double-helical structure; recently, it was reported to have ...

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

Unusual DNA binding modes for metal anticancer complexes [PDF]
DNA is believed to be the primary target for many metal-based drugs. For example, platinum-based anticancer drugs can form specific lesions on DNA that induce apoptosis.

Application of Ammonium Persulfate for Selective Oxidation of Guanines for Nucleic Acid Sequencing
Nucleic acids can be sequenced by a chemical procedure that partially damages the nucleotide positions at their base repetition. Many methods have been reported for the selective recognition of guanine.

G-quartet biomolecular nanowires
We present a first-principle investigation of quadruple helix nanowires, consisting of stacked planar hydrogen-bonded guanine tetramers. Our results show that long wires form and are stable in potassium-rich conditions.
