Dissociative multi-photon ionization of isolated uracil and uracil-adenine complexes [PDF]
International Journal of Mass Spectrometry, 2016 Recent multi-photon ionization (MPI) experiments on uracil revealed a fragment ion at m/z 84 that was proposed as a potential marker for ring opening in the electronically excited neutral molecule.

A unique uracil-DNA binding protein of the uracil DNA glycosylase superfamily [PDF]
Nucleic Acids Research, 2015 Uracil DNA glycosylases (UDGs) are an important group of DNA repair enzymes, which pioneer the base excision repair pathway by recognizing and excising uracil from DNA.

Uracil-DNA glycosylases preferentially excise mispaired uracil [PDF]
Biochemical Journal, 1992 We have investigated the substrate specificity of human, viral and bacterial uracil-DNA glycosylases employing as substrate double-stranded oligonucleotides containing in the same position of the 5′-32P-labelled strand an uracil residue facing, on the complementary strand, guanine (mimicking cytosine deamination) or adenine (mimicking dUTP ...

Uracil mustard revisited [PDF]
Cancer, 1999 A patient with diffuse large cell lymphoma who had a complete response lasting 35 years following a 3-day course of uracil mustard stimulated a recall review of patients treated with this oral alkylating agent.Records of patients treated with uracil mustard between 1958 and 1970 were reviewed.
