- 7-(4,5-cis-Dihydroxy-1-cyclopenten-3-ylaminomethyl)-7-deazaguanosineNucleoside Q
Queuosine is a modified purine nucleoside that is found in the cell-wall peptidoglycan of bacteria. It can be synthesized by the enzymatic conversion of inosine to queuosine with sodium citrate, or it can be obtained from bovine fetal calf serum that has been treated with queuine (a natural amino acid). The reaction mechanism for this conversion is not well understood but it has been shown that queuosine has a number of enzyme activities, including nucleotide phosphoribosyltransferase, mitochondrial functions and eukaryotic DNA synthesis. Queuosine also has a redox potential between -0.2 and -1.8 volts, which makes it an effective antioxidant. Queuosine's antioxidant properties may be due to its ability to donate a pair of electrons to reduce molecular oxygen to hydrogen peroxide, which can then be converted into water by superoxide dismutase or glutathione per
