A nonafluoro nucleoside as a sensitive 19f NMR probe of nucleic acid conformation.
Organic Letters, 2008 A nucleoside carrying a perfluorinated tert-butyl group ( 4) was prepared by a Sonogashira coupling of 5-iodo-2'-deoxyuridine with 4,4,4-trifluoro-3,3-bis(trifluoromethyl)-1-butyne in nearly quantitative yield and subsequently incorporated into DNA ...

Conformation of nucleic acids and the analysis of the hypochromic effect [PDF]
Biochemical Journal, 1970 The spectra of two double-helical RNA species isolated from virus-like particles found in the mycelium of Penicillium chrysogenum were measured at about 25 degrees C, and at 95 degrees C after denaturation to a single-stranded form, and compared with the spectrum of the equivalent mixture of nucleotides.

Molecular Dynamics Analysis of Biomolecular Systems Including Nucleic Acids [PDF]
arXiv, 2021 Along with recent progress in structural biology and genome biology, structural dynamics of molecular systems including nucleic acids has attracted attention in the context of gene regulation. Structure-function relationship is an important topic, where physicochemical properties of nucleotides are important as well as those of amino acids in proteins.

Highly Improved Electrospray Ionization-Mass Spectrometry Detection of G-Quadruplex-Folded Oligonucleotides and Their Complexes with Small Molecules [PDF]
, 2017 G-quadruplexes are nucleic acids structures stabilized by physiological concentration of potassium ions. Because low stability G-quadruplexes are hardly detectable by mass spectrometry, we optimized solvent conditions: isopropanol in a triethylamine ...

RNA Folding Pathways in Stop Motion [PDF]
Nucleic Acids Research 44, 5883 (2016), 2016 We introduce a method for predicting RNA folding pathways, with an application to the most important RNA tetraloops. The method is based on the idea that ensembles of three-dimensional fragments extracted from high-resolution crystal structures are heterogeneous enough to describe metastable as well as intermediate states.
