Molecular rectifiers with very high rectification ratio enabled by oxidative damage in double-stranded DNA [PDF]
J. Phys. Chem. B 2022, 126, 25, 4636-4646, 2022 In this work, we report a novel strategy to construct molecular diodes with a record tunable rectification ratio of as high as 10^6 using oxidatively damaged DNA molecules. Being exposed to several endogenous and exogenous events, DNA suffers constant oxidative damages leading to oxidation of guanine to 8-Oxoguanine (8oxoG).

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-triamino-5(2H)-oxazolone (Oz), guanidinoformimine (Gf), guanidinohydantoin/iminoallantoin (Gh/Ia ...

Revisiting the Neutral Dynamics Derived Limiting Guanine-Cytosine Content Using the Human De Novo Point Mutation Data [PDF]
Meta Gene 31: 100994 (2022), 2020 We revisit the topic of human genome guanine-cytosine content under neutral evolution. For this study, the de novo mutation data within human is used to estimate mutational rate instead of using base substitution data between related species. We then define a new measure of mutation bias which separate the de novo mutation counts from the background ...

Modulation of guanine deaminase [PDF]
Biochemical Journal, 1973 1. Guanine deaminases purified from the 15000g supernatant fraction of iso-osmotic sucrose homogenates of rat and mouse liver and brain were tested for the influence of GTP and allantoin. 2. The suffixes A and B were assigned to the isoenzyme fractions eluted from DEAE-cellulose with the lower and the higher molarity of eluent respectively. Isoenzyme A

Molecules, 2023 Quadruplexes (GQs), peculiar DNA/RNA motifs concentrated in specific genomic regions, play a vital role in biological processes including telomere stability and, hence, represent promising targets for anticancer therapy. GQs are formed by folding guanine-
