Common Name8-oxo-GMP
Description8-oxo-GMP is a modified nucleotide belonging to the class of oxidized guanosine monophosphates. Its chemical structure features an oxidized guanine base, which is a result of oxidative stress, leading to the formation of reactive oxygen species. In cellular pathways, 8-oxo-GMP is involved in nucleotide metabolism, particularly through its conversion and interconversion with other oxidized nucleotides. For instance, it can be produced from the hydrolysis of 8-oxo-GTP and 8-oxo-dGTP by specific enzymes such as GTP cyclohydrolase II (PMID:9756871 ). Moreover, the MutT protein plays a crucial role in preventing the misincorporation of 8-oxo-GMP into DNA by cleaving 8-oxo-GTP and 8-oxo-GDP, thus regulating its levels and preventing the formation of 8-oxo-GDP from 8-oxo-GMP (PMID:23376345 ). Additionally, purified enzymes exhibit 5' nucleotidase activity on 8-oxo-GMP, highlighting its biochemical relevance (PMID:20658964 ). Overall, 8-oxo-GMP serves as a significant intermediate in the oxidative nucleotide metabolism, reflecting the cellular response to oxidative damage.
