Role of the Escherichia coli and human DNA glycosylases that remove 5-formyluracil from DNA in the prevention of mutations.

J. Radiat. Res. 42(1) , 11-9, (2001)

Ionizing radiation induces a wide variety of modifications to purine and pyrimidine residues. The exocyclic methyl group of thymine does not escape oxidative damage. Any 5-hydroperoxymethyluracil prod...

Repair of the mutagenic DNA oxidation product, 5-formyluracil.

DNA Repair (Amst.) 2(2) , 199-210, (2003)

The oxidation of the thymine methyl group can generate 5-formyluracil (FoU). Template FoU residues are known to miscode, generating base substitution mutations. The repair of the FoU lesion is therefo...

Nucleotide excision repair of 5-formyluracil in vitro is enhanced by the presence of mismatched bases.

Biochemistry 43(10) , 2682-7, (2004)

5-Formyluracil (fU) is a major thymine lesion produced by reactive oxygen radicals and photosensitized oxidation. Although this residue is a potentially mutagenic lesion and is removed by several base...
