The Uses of 2'-Deoxyguanosine

2'-Deoxyguanosine (Deoxyguanosine; dG) is composed of the purine nucleoside guanine linked by its N9 nitrogen to the C1 carbon of deoxyribose. It is a purine nucleoside that upon sequential phosphoylation (kinases) forms dGTP which is used by DNA polymerases and reverse transcriptases to synthesis DNA(s). Deoxyguanosine is the most electron rich of the four canonical bases and includes many nucleophilic sites which are susceptible to oxidative damage. This makes deoxyguanosine and its oxidized derivatives useful reagents to study mechanisms of oxidative damage to nucleosides and nucleotides.

Definition

ChEBI: 2'-deoxyguanosine is a purine 2'-deoxyribonucleoside having guanine as the nucleobase. It has a role as a Saccharomyces cerevisiae metabolite, a human metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a purines 2'-deoxy-D-ribonucleoside and a purine 2'-deoxyribonucleoside. It is functionally related to a guanosine.

Purification Methods

2'-Deoxyguanosine recrystallises from H2O as the monohydrate. [Brown &C5440 Lythgoe J Chem Soc 1990 1950, L
