Metabolite Identification
Common Name8-oxo-GDP
Description8-oxo-GDP is a modified guanosine diphosphate, classified as an oxidized nucleotide. Its chemical structure features a guanine base linked to a ribose sugar and two phosphate groups, with the distinctive presence of an oxygen atom at the 8-position of the guanine ring, resulting from oxidative damage. This metabolite is generated through the oxidation of GDP by reactive oxygen species and can be converted to 8-oxo-GTP by nucleoside-diphosphate kinase and adenylate kinase, which do not differentiate between 8-oxo-GDP and normal GDP (PMID:23376345 ). The enzyme MtuMutT1 plays a crucial role in the conversion of 8-oxo-dGTP to 8-oxo-dGDP and 8-oxo-GTP to 8-oxo-GDP (PMID:23463507 ). Additionally, 8-oxo-GDP can be cleaved by MutT protein, which also degrades it to 8-oxo-GMP, although it acts less efficiently on oxidized GMP (PMID:23376345 ). The enzyme MTH3 can degrade 8-oxo-GDP with comparable efficiency to 8-oxo-dGDP, while MTH1 and MTH2 show limited activity against 8-oxo-GTP (PMID:22556419 ). Overall, 8-oxo-GDP is involved in pathways related to nucleotide metabolism and oxidative stress responses.
