Poxvirus uracil‐DNA glycosylase—An unusual member of the family I uracil‐DNA glycosylases [PDF]
Protein Science, 2016 AbstractUracil‐DNA glycosylases are ubiquitous enzymes, which play a key role repairing damages in DNA and in maintaining genomic integrity by catalyzing the first step in the base excision repair pathway. Within the superfamily of uracil‐DNA glycosylases family I enzymes or UNGs are specific for recognizing and removing uracil from DNA.

Uracil-DNA glycosylase. Purification and properties of uracil-DNA glycosylase from Micrococcus luteus. [PDF]
Journal of Biological Chemistry, 1982 A uracil-DNA-glycosylase from Micrococcus luteus has been purified more than 3,000-fold. The enzyme preparation appears homogeneous, according to the results of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. It is devoid of nonspecific endonucleases, specific endonucleases for apurinic and apyrimidinic sites, 3-methyladenine or 7 ...

A mutant of uracil DNA glycosylase that distinguishes between cytosine and 5-methylcytosine. [PDF]
PLoS ONE, 2014 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 ...

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. Based on two short conserved sequences (motifs A and B), UDGs have been classified into six families. Here we report a novel UDG, UdgX, from Mycobacterium smegmatis and other organisms.

Phylogenomic Analysis of the Uracil-DNA Glycosylase Superfamily [PDF]
Molecular Biology and Evolution, 2010 The spontaneous deamination of cytosine produces uracil mispaired with guanine in DNA, which will produce a mutation, unless repaired. In all domains of life, uracil-DNA glycosylases (UDGs) are responsible for the elimination of uracil from DNA.

Mass spectrometry-based analysis of macromolecular complexes of Staphylococcus aureus uracil-DNA glycosylase and its inhibitor reveals specific variations due to naturally occurring mutations. [PDF]
FEBS Open Bio, 2019 The base excision repair pathway plays an important role in correcting damage induced by either physiological or external effects. This repair pathway removes incorrect bases from the DNA.

Bacillus Calmette-Guerin Increases Base Excision Repair in Bladder Cancer Cells
Journal of Urological Surgery, 2021 Objective:Most patients with non-muscle-invasive bladder cancer (NMIBC) do not respond to intravesical Bacillus Calmette-Guerin (BCG) immunotherapy and have high risk of NMIBC recurrence and progression.

Chicken MBD4 Regulates Immunoglobulin Diversification by Somatic Hypermutation
Frontiers in Immunology, 2019 Immunoglobulin (Ig) diversification occurs via somatic hypermutation (SHM) and class switch recombination (CSR), and is initiated by activation-induced deaminase (AID), which converts cytosine to uracil.

Mechanisms of base selection by human single-stranded selective monofunctional uracil-DNA glycosylase [PDF]
, 2009 hSMUG1 (human single-stranded selective monofunctional uracil-DNA glyscosylase) is one of three glycosylases encoded within a small region of human chromosome 12. Those three glycosylases, UNG (uracil-DNA glycosylase), TDG (thymine-DNA glyscosylase), and

FACT Assists Base Excision Repair by Boosting the Remodeling Activity of RSC. [PDF]
PLoS Genetics, 2016 FACT, in addition to its role in transcription, is likely implicated in both transcription-coupled nucleotide excision repair and DNA double strand break repair.
