2'-Deoxyguanosine 5'-monophosphate (dGMP) is used as a substrate of guanylate kinases to generate dGDP, which in turn is phosphorylated to dGTP, a nucleotide precursor used in DNA synthesis. In addition, dGMP can be efficiently phosphorylated by the type I thymidylate kinase of the malarial agent P. falciparum. In humans, deficiency of mitochondrial deoxyguanosine kinase, which synthesizes dGMP from ATP and deoxyguanosine, contributes to mitochondrial DNA depletion syndrome.
2'-Deoxyguanosine 5'-monophosphate (sodium salt hydrate)
2'-Deoxyguanosine 5'-monophosphate (sodium salt hydrate) is an oxidizable target of the photosensitizer pterin (PT) and can be used to evaluate the photosensitizing properties of biopterins (such as Bip, Fop and Cap) . Pterin causes a photosensitive reaction of dGMP under UV-A radiation, causing damage to DNA molecules. There are two main mechanisms for the photosensitive oxidation of purine nucleotides by pterin in vitro: one is the hydrogen abstraction reaction of electron transfer from dGMP to the triplet excited state of pterin (type I mechanism), and the other is the interaction between dGMP and pterin. The reaction produces singlet molecular oxygen (1O2) (Type II mechanism).
