Products of Oxidative Guanine Damage Form Base Pairs with Guanine [PDF]
International Journal of Molecular Sciences, 2020 Among the natural bases, guanine is the most oxidizable base. The damage caused by oxidation of guanine, commonly referred to as oxidative guanine damage, results in the formation of several products, including 2,5-diamino-4H-imidazol-4-one (Iz), 2,2,4 ...

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,

Guanine crystal formation by bacteria [PDF]
BMC Biology, 2023 Background Guanine crystals are organic biogenic crystals found in many organisms. Due to their exceptionally high refractive index, they contribute to structural color and are responsible for the reflective effect in the skin and visual organs in ...

Generation, repair and replication of guanine oxidation products
Genes and Environment, 2017 Guanine is the most readily oxidized of the four DNA bases, and guanine oxidation products cause G:C-T:A and G:C-C:G transversions through DNA replication.

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 ...
