Solution conformation of 2-aminopurine dinucleotide determined by ultraviolet two-dimensional fluorescence spectroscopy

open access: yesNew Journal of Physics, 2013
We have observed the conformation-dependent electronic coupling between the monomeric subunits of a dinucleotide of 2-aminopurine (2-AP), a fluorescent analogue of the nucleic acid base adenine.

Snf2 family ATPases and DExx box helicases:differences and unifying concepts from high-resolution crystal structures [PDF]

open access: yes, 2006
Proteins with sequence similarity to the yeast Snf2 protein form a large family of ATPases that act to alter the structure of a diverse range of DNA–protein structures including chromatin. Snf2 family enzymes are related in sequence to DExx box helicases,

Identification of G-quadruplex DNA/RNA binders: Structure-based virtual screening and biophysical characterization [PDF]

open access: yes, 2017
Background Recent findings demonstrated that, in mammalian cells, telomere DNA (Tel) is transcribed into telomeric repeat-containing RNA (TERRA), which is involved in fundamental biological processes, thus representing a promising anticancer target. For

Microgels and apparatus for PAGE of nucleic acids in one or two dimensions

open access: yesBioTechniques, 2018
We describe a system for horizontal 1D or 2D PAGE comprising an apparatus and microgels. There is no buffer outside the gel, making handling and sample loading easy.

T7 RNA polymerase functions in vitro without clustering. [PDF]

open access: yesPLoS ONE, 2012
Many nucleic acid polymerases function in clusters known as factories. We investigate whether the RNA polymerase (RNAP) of phage T7 also clusters when active.

TFE and Spt4/5 open and close the RNA polymerase clamp during the transcription cycle [PDF]

open access: yes, 2016
Transcription is an intrinsically dynamic process and requires the coordinated interplay of RNA polymerases (RNAPs) with nucleic acids and transcription factors.

First High-Resolution Crystal Structures of DNA:2′-O-Methyl-RNA Heteroduplexes

open access: yesCrystals, 2022
Heteroduplexes composed of all-DNA and all-2′-OMe RNA strands do not occur in nature, but they have found application in the development of molecular beacons and could also be used as aptamers or elements of nucleic acid-based nanostructures that will ...
