Biogenic Guanine Crystals Are Solid Solutions of Guanine and Other Purine Metabolites [PDF]
Journal of the American Chemical Society, 2022 Highly reflective crystals of the nucleotide base guanine are widely distributed in animal coloration and visual systems. Organisms precisely control the morphology and organization of the crystals to optimize different optical effects, but little is known about how this is achieved.

Guanine-vacancy–bearing G-quadruplexes responsive to guanine derivatives [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2015 Significance Guanine-rich nucleic acids fold into a four-stranded structure named G-quadruplex that has implications in essential cellular processes, pharmaceutical applications, and nanodevices. We found a unique type of G-quadruplex that contains a G-vacancy and is stabilized by guanine derivatives such as te physiological ...

Engineering Proceedings, 2023 Pathogens can be detected electrochemically by measuring guanine oxidation signals generated from RNA or DNA hybridized to a biosensor working electrode. However, the associated limit of detection (LOD) is not sufficiently low for widespread clinical use.

Diversity of Parallel Guanine Quadruplexes Induced by Guanine Substitutions [PDF]
International Journal of Molecular Sciences, 2020 Recently, we reported an inhibitory effect of guanine substitutions on the conformational switch from antiparallel to parallel quadruplexes (G4) induced by dehydrating agents. As a possible cause, we proposed a difference in the sensitivity of parallel and antiparallel quadruplexes to the guanine substitutions in the resulting thermodynamic stability ...

Tautomerism of Guanine Analogues [PDF]
Biomolecules, 2020 Tautomerism of nucleic acid (NA) bases is a crucial factor for the maintenance and translation of genetic information in organisms. Only canonical tautomers of NA bases can form hydrogen-bonded complexes with their natural counterparts. On the other hand, rare tautomers of nucleobases have been proposed to be involved in processes catalysed by NA ...
