Structure and stereochemistry of the base excision repair glycosylase MutY reveal a mechanism similar to retaining glycosidases. [PDF]

open access: yes, 2015
MutY adenine glycosylases prevent DNA mutations by excising adenine from promutagenic 8-oxo-7,8-dihydroguanine (OG):A mismatches. Here, we describe structural features of the MutY active site bound to an azaribose transition state analog which indicate a

Uracil Accumulation and Mutagenesis Dominated by Cytosine Deamination in CpG Dinucleotides in Mice Lacking UNG and SMUG1

open access: yesScientific Reports, 2017
Both a DNA lesion and an intermediate for antibody maturation, uracil is primarily processed by base excision repair (BER), either initiated by uracil-DNA glycosylase (UNG) or by single-strand selective monofunctional uracil DNA glycosylase (SMUG1).

Heat‐labile uracil‐DNA glycosylase: purification and characterization [PDF]

open access: yesFEBS Letters, 1996
A uracil‐DNA glycosylase (UNG) from a psychrophilic marine bacterium (BMTU 3346) has been purified to apparent homogeneity. The enzyme has a molecular weight of 23 400 Da. It is stable in complex buffers (containing glycerol/BSA), whereas it is heat‐labile in dilute buffers (free of stabilizers) with a half‐life of 2 min at 40°C.

A Method for Constructing Nucleosome Arrays with Spatially Defined Histone PTMs and DNA Damage

open access: yesAngewandte Chemie, EarlyView.
This work advances methodology by addressing challenges in mimicking the complex in vivo spatial relationships of histone acetylation and DNA damage. The combination of an abiotic/enzymatic hybrid catalyst system (ABEHCS) and the plug‐and‐play method has constituted a versatile platform to construct nucleosome arrays with precise histone acetylation ...

Real-time PCR method for detection of short DNA using a deoxyuridine probe and application for detection of fomivirsen

open access: yesBioTechniques, 2022
This study sought to develop a short DNA detection method using a deoxyuridine probe and polymerase chain reaction. The probe was hybridized to the target short DNA, which was then extended by DNA polymerase.

Direct Measurement of the Substrate Preference of Uracil-DNA Glycosylase [PDF]

open access: yesJournal of Biological Chemistry, 1998
Site-directed mutants of the herpes simplex virus type 1 uracil-DNA glycosylase lacking catalytic activity have been used to probe the substrate recognition of this highly conserved and ubiquitous class of DNA-repair enzyme utilizing surface plasmon resonance. The residues aspartic acid-88 and histidine-210, implicated in the catalytic mechanism of the

A Novel 3-Methyladenine DNA Glycosylase from Helicobacter pylori Defines a New Class within the Endonuclease III Family of Base Excision Repair Glycosylases [PDF]

open access: yes, 2000
The cloning, purification, and characterization of MagIII, a 3-methyladenine DNA glycosylase from Helicobacter pylori, is presented in this paper. Sequence analysis of the genome of this pathogen failed to identify open reading frames potentially coding ...

Plant mitochondria possess a short-patch base excision DNA repair pathway [PDF]

open access: yes, 2009
Despite constant threat of oxidative damage, sequence drift in mitochondrial and chloroplast DNA usually remains very low in plant species, indicating efficient defense and repair.
