Uracil-DNA Glycosylase in the Extreme Thermophile Archaeoglobus fulgidus [PDF]

Journal of Biological Chemistry, 2000
Uracil-DNA glycosylase (UDG) is an essential enzyme for maintaining genomic integrity. Here we describe a UDG from the extreme thermophile Archaeoglobus fulgidus. The enzyme is a member of a new class of enzymes found in prokaryotes that is distinct from the UDG enzyme found in Escherichia coli, eukaryotes, and DNA-containing viruses. The A.

Bacillus subtilis RNase HII Is Inefficient at Processing Guanosine Monophosphate and Damaged Ribonucleotides

Molecular Microbiology, EarlyView.
Bacillus subtilis RNase HII corrects ribonucleotide errors and mismatched ribonucleotides, but not damaged ribonucleotides. Mismatched ribonucleotides would also serve as substrates for mismatch repair while damaged ribonucleotides would be addressed through base excision repair.

Colorimetric and electrochemical dual-signal detection of uracil-DNA glycosylase using functionalized pure DNA hydrogel on paper-based analytical devices

Advanced Agrochem, 2023
The development of simple and accurate detection of uracil-DNA glycosylase (UDG) is of great significance for early clinical diagnosis and biomedical research. Here, we on the first effort introduced the uracil bases into the rolling circle amplification

The PagDMG6341–PagWD40–PagPOLD4 Module Coordinates Base Excision Repair in ‘84K’ Poplar (Populus alba × P. glandulosa)

Plant Biotechnology Journal, EarlyView.
ABSTRACT Base excision repair (BER) is a critical pathway for repairing damaged DNA bases in cells; however, the mechanisms of protein recruitment and interaction in this pathway remain largely unexplored in higher plants. In this study, we used ‘84K’ poplar (Populus alba × P.

The kinetics of uracil-N-glycosylase distribution inside replication foci

Scientific Reports
Mismatched nucleobase uracil is commonly repaired through the base excision repair initiated by DNA uracil glycosylases. The data presented in this study strongly indicate that the nuclear uracil-N-glycosylase activity and nuclear protein content in ...

Repair of Hypoxanthine in DNA Revealed by DNA Glycosylases and Endonucleases From Hyperthermophilic Archaea

Frontiers in Microbiology, 2021
Since hyperthermophilic Archaea (HA) thrive in high-temperature environments, which accelerate the rates of deamination of base in DNA, their genomic stability is facing a severe challenge.

Endocytic Programming via Porous Silicon Nanoparticles Enhances TLR4 Nanoagonist Potency for Macrophage‐Mediated Immunotherapy

Advanced Functional Materials, Volume 36, Issue 5, 15 January 2026.
Porous silicon nanoparticles (PSiNPs) reprogram macrophage endocytosis of manganese@albumin‐based TLR4 nanoagonists, driving TRIF‐biased TLR4 signaling, eliciting robust proinflammatory responses, and potentiating macrophage‐mediated immunotherapeutic effects against NSCLC.

Determination of Methylation Site of DNA-Methyltransferase NlaX by a Hybrid Method

BioTechniques, 2002
Using a new method based on a combination of bisulfite reaction, the repair enzyme uracil-DNA glycosylase, and synthetic oligodeoxyribonucleotides, the methylation site of DNA-methyltransferase NlaX (M·NlaX) from Neisseria lactamica was established to be

The Double Face of Base Excision Repair: Preventing and Triggering Double‐Strand Breaks

BioEssays, Volume 48, Issue 1, January 2026.
Base excision repair is conserved from bacteria to man, robustly eliminating oxidized bases in DNA and reinserting the appropriate nucleotide to restore an intact double helix. Recent results describe conditions and mechanisms that misregulate long‐patch BER to generate double‐strand breaks, triggering chromosome fragmentation and cell death, altering ...

N6-methyladenosine in DNA promotes genome stability

eLife
DNA base lesions, such as incorporation of uracil into DNA or base mismatches, can be mutagenic and toxic to replicating cells. To discover factors in repair of genomic uracil, we performed a CRISPR knockout screen in the presence of floxuridine, a ...
