Escherichia coli DNA repair helicase Lhr is also a uracil-DNA glycosylase [PDF]
DNA glycosylases protect genetic fidelity during DNA replication by removing potentially mutagenic chemically damaged DNA bases. Bacterial Lhr proteins are well-characterized DNA repair helicases that are fused to additional 600–700 amino acids of ...

Structural basis for uracil removal from DNA by human SMUG1. [PDF]
Human single-strand-selective monofunctional uracil DNA glycosylase 1 (hSMUG1) removes uracil, 5-hydroxymethyluracil (5hmU) and 5-fluorouracil (5FU) from DNA, thereby initiating the base excision repair (BER) process.

A mutant of uracil DNA glycosylase that distinguishes between cytosine and 5-methylcytosine [PDF]
We demonstrate that a mutant of uracil DNA glycosylase (N123D:L191A) distinguishes between cytosine and methylcytosine. Uracil DNA glycosylase (UDG) efficiently removes uracil from DNA in a reaction in which the base is flipped into the enzyme’s active ...

Architecturally diverse proteins converge on an analogous mechanism to inactivate Uracil-DNA glycosylase [PDF]
Uracil-DNA glycosylase (UDG) compromises the replication strategies of diverse viruses from unrelated lineages. Virally encoded proteins therefore exist to limit, inhibit or target UDG activity for proteolysis.

Cytosine-to-Uracil Deamination by SssI DNA Methyltransferase [PDF]
The prokaryotic DNA(cytosine-5)methyltransferase M.SssI shares the specificity of eukaryotic DNA methyltransferases (CG) and is an important model and experimental tool in the study of eukaryotic DNA methylation.

A function of thymine DNA glycosylase-initiated DNA repair in maintaining epigenome stability [PDF]
The Thymine DNA Glycosylase (TDG) was initially discovered by its ability to excise the deamination products of cytosine and 5-methylcytosine (5-mC), and therefore thought to initiate base excision repair (BER) of the resulting G•U and G•T mismatches.

Ground State Destabilization in Uracil DNA Deglycosylase (UDG): Let’s Not Forget “Tautomeric Strain” in Substrates [PDF]
QM and QM/MM computations reveal that some enzymes, like the uracil DNA deglycosylase, may achieve ground state destabilization through substrate "tautomeric strain.

The importance of the fifth nucleotide in DNA: Uracil
Uracil is a ribonucleotide found in both DNA and RNA, with the main difference between the two being the presence of thymine in DNA and uracil in RNA. Although thymine and uracil are similar in function and can form the same base pairs with adenine, the ...

Targeted rapid amplification of cDNA ends (T-RACE)-an improved RACE reaction through degradation of non-target sequences [PDF]
Amplification of the 5' ends of cDNA, although simple in theory, can often be difficult to achieve. We describe a novel method for the specific amplification of cDNA ends. An oligo-dT adapter incorporating a dUTP-containing PCR primer primes first-strand
