5-Formyluracil is a major oxidation product of thymine, formed in DNA in yields comparable to that of 8-oxo-7,8-dihydroguanine by exposure to gamma-irradiation. Whereas the repair pathways for removal and the biological effects of persisting 8-oxo-7,8-dihydroguanine are much elucidated, much less

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 produced is spontaneously decomposed to form 5-formyluracil (5-foU) and 5-hydroxymethyluracil. The yield of 5-foU
Pingfang Liu et al.
DNA repair, 2(2), 199-210 (2003-01-18)
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 therefore important in minimizing mutations induced by DNA oxidation. We have

We here present a novel covalently linked base pair via Schiff base formation between 5-formyluracil (fU) and 5-aminocytosine (AmC). The formation of Schiff base remarkably increases thermal stability of the duplex DNA, whereas it completely dissociates upon heating at 90

Oxidatively damaged thymine, 5-formyluracil (5-fU), was incorporated into a predetermined site of double-stranded shuttle vectors. The nucleotide sequences in which the modified base was incorporated were 5'-CFTAAG-3' and 5'-CTFAAG-3' (F represents 5-fU), the recognition site for the restriction enzyme AflII
