Determination of laser-induced thymine–thymine dimer in DNA by LC

Journal of Pharmaceutical and Biomedical Analysis, 2002
A new simple and selective high-performance liquid chromatography (HPLC) method has been developed for the determination of thymine-thymine (T-T) dimer in deoxyribonucleic acid (DNA) for the study of relationship between the yield of T-T dimer and laser irradiation conditions. The HPLC method is not disturbed by other hydrolysate formed in DNA with the

DNA base stacking: The stacked uracil/uracil and thymine/thymine minima

Journal of Computational Chemistry, 2012
AbstractThe potential energy surfaces of stacked uracil dimer (U/U) and stacked thymine dimer (T/T) have been explored at the counterpoise (CP)‐corrected M06‐2X/6‐31+G(d) level of theory, in the gas phase and in solution (with water and, for U/U, 1,4‐dioxane as the solvents) modeled by a continuum solvent using the polarizable continuum model ...

Quantitative extraction of thymine-thymine dimer from a large excess of thymine by preparative liquid chromatography

Journal of Chromatography A, 1989
Abstract Extremely small amounts of thymine-thymine dimer can be extracted from thymine solutions using overloaded elution and shaving a narrow fraction at the front of the overloaded, later eluting thymine band. A two- or three-step procedure, involving the concentration and reinjection of the collected fraction, permits the preparation of solutions

Spectroscopic Evaluation of Novel Adenine/Thymine-Conjugated Naphthalenediimides: Preference of Adenine-Adenine over Thymine-Thymine Intermolecular Hydrogen Bonding in Adenine- and Thymine-Functionalized Naphthalenediimides

Journal of Fluorescence, 2019
The synthesis and spectroscopic characterization of novel nucleobase (adenine/thymine)-conjugated naphthalenediimides (NDIs), namely, NDI-AA, NDI-TT, and NDI-AT have been successfully achieved. NDI-AA, NDI-TT and NDI-AT have similar absorption in the 300-400 nm region.

Selectivity for thymine over 5-bromouracil by a thymine-requiring bacterium

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1966
Abstract The relative incorporation of thymine and its analogue, 5-bromouracil, into the DNA of a thymine-requiring bacterium was studied under a variety of conditions. Exponentially growing cultures of Escherichia coli strain TAU-bar were transferred to media containing defined amounts of thymine and 5-bromouracil.

Electronic Coupling Mediated by Stacked [Thymine-Hg-Thymine] Base Pairs

The Journal of Physical Chemistry B, 2006
Very recently it has been shown that stable metal-mediated base pairs [Thymine-Hg-Thymine] can form in DNA. To estimate the effect of such pairs on the efficiency of charge transfer through DNA, we carry out quantum mechanical calculations of double-stranded pi-stacks GXG, GXXG, and GXXXG, where X = [Thymine-Hg-Thymine] and stacks GT(n)G of canonical ...
