Three-dimensional modeling of single stranded DNA hairpins for aptamer-based biosensors. [PDF]

open access: yes, 2017
Aptamers consist of short oligonucleotides that bind specific targets. They provide advantages over antibodies, including robustness, low cost, and reusability.

Progress in ion detection and clinical diagnosis based on G-quadruplex combined with fluorescence properties

open access: yesAdvanced Sensor and Energy Materials
G-quadruplex is a high-level structure composed of folded DNA or RNA rich in tandem repeats of guanine (G). In recent years, G-quadruplex is widely used in various fields due to its unique structural properties.

The Presence and Localization of G-Quadruplex Forming Sequences in the Domain of Bacteria

open access: yesMolecules, 2019
The role of local DNA structures in the regulation of basic cellular processes is an emerging field of research. Amongst local non-B DNA structures, the significance of G-quadruplexes was demonstrated in the last decade, and their presence and functional

G-quadruplex DNA motifs in the malaria parasite Plasmodium falciparum and their potential as novel antimalarial drug targets [PDF]

open access: yes, 2018
G-quadruplexes are DNA or RNA secondary structures that can be formed from guanine-rich nucleic acids. These four-stranded structures, composed of stacked quartets of guanine bases, can be highly stable and have been demonstrated to occur in vivo in the ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

G4mismatch: Deep neural networks to predict G-quadruplex propensity based on G4-seq data.

open access: yesPLoS Computational Biology, 2023
G-quadruplexes are non-B-DNA structures that form in the genome facilitated by Hoogsteen bonds between guanines in single or multiple strands of DNA.

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

Tuning Thermoresponsive Supramolecular G-Quadruplexes [PDF]

open access: yesLangmuir, 2015
Thermoresponsive systems are attractive due to their suitability for fundamental studies as well as their practical uses in a wide variety of applications. While much progress has been achieved using polymers, alternative strategies such as the use of well-defined nonpolymeric supramolecules are still underdeveloped.

G-Quadruplexes in the Archaea Domain [PDF]

open access: yesBiomolecules, 2020
The importance of unusual DNA structures in the regulation of basic cellular processes is an emerging field of research. Amongst local non-B DNA structures, G-quadruplexes (G4s) have gained in popularity during the last decade, and their presence and functional relevance at the DNA and RNA level has been demonstrated in a number of viral, bacterial ...
