DNA glycosylases: in DNA repair and beyond [PDF]
The base excision repair machinery protects DNA in cells from the damaging effects of oxidation, alkylation, and deamination; it is specialized to fix single-base damage in the form of small chemical modifications. Base modifications can be mutagenic and/

Intrinsic Strand-Incision Activity of Human UNG: Implications for Nick Generation in Immunoglobulin Gene Diversification [PDF]
Uracil arises in cellular DNA by cytosine (C) deamination and erroneous replicative incorporation of deoxyuridine monophosphate opposite adenine. The former generates C → thymine transition mutations if uracil is not removed by uracil-DNA glycosylase ...

The Evolutionary Diversity of Uracil DNA Glycosylase Superfamily [PDF]
Uracil DNA glycosylase (UDG) is a crucial member in the base excision (BER) pathway that is able to specially recognize and cleave the deaminated DNA bases, including uracil (U), hypoxanthine (inosine, I), xanthine (X) and oxanine (O).

A rapid reaction analysis of uracil DNA glycosylase indicates an active mechanism of base flipping [PDF]
Uracil DNA glycosylase (UNG) is the primary enzyme for the removal of uracil from the genome of many organisms. A key question is how the enzyme is able to scan large quantities of DNA in search of aberrant uracil residues.

Helix–hairpin–helix protein MJ1434 from Methanocaldococcus jannaschii and EndoIV homologue TTC0482 from Thermus thermophilus HB27 do not process DNA uracil residues [PDF]
The mutagenic threat of hydrolytic DNA cytosine deamination is met mostly by uracil DNA glycosylases (UDG) initiating base excision repair. However, several sequenced genomes of archaeal organisms are devoid of genes coding for homologues of the ...

The Methanothermobacter thermautotrophicus ExoIII homologue Mth212 is a DNA uridine endonuclease [PDF]
The genome of Methanothermobacter thermautotrophicus, as a hitherto unique case, is apparently devoid of genes coding for general uracil DNA glycosylases, the universal mediators of base excision repair following hydrolytic deamination of DNA cytosine ...
