Structure of Formamidopyrimidine-DNA Glycosylase Covalently Complexed to DNA [PDF]

open access: yesJournal of Biological Chemistry, 2002
Formamidopyrimidine-DNA glycosylase (Fpg) is a DNA repair enzyme that excises oxidized purines from damaged DNA. The Schiff base intermediate formed during this reaction between Escherichia coli Fpg and DNA was trapped by reduction with sodium borohydride, and the structure of the resulting covalently cross-linked complex was determined at a 2.1-A ...

Mechanism of Werner DNA helicase: POT1 and RPA stimulates WRN to unwind beyond gaps in the translocating strand. [PDF]

open access: yesPLoS ONE, 2009
WRN belongs to the RecQ family of DNA helicases and it plays a role in recombination, replication, telomere maintenance and long-patch base excision repair. Here, we demonstrate that WRN efficiently unwinds DNA substrates containing a 1-nucleotide gap in

The DNA Repair Protein XRCC1 Functions in the Plant DNA Demethylation Pathway by Stimulating Cytosine Methylation (5-meC) Excision, Gap Tailoring, and DNA Ligation [PDF]

open access: yes, 2013
Background: Active DNA demethylation in plants is initiated by 5-meC DNA glycosylases of the ROS1/DME family and continued through a base excision repair pathway.

Uracil-DNA glycosylase as a probe for protein-DNA interactions [PDF]

open access: yesNucleic Acids Research, 1993
The DNA repair enzyme Uracil-DNA Glycosylase (UDG) can be used to investigate three different features of protein-DNA interactions. Complexes can be probed by simple protection experiments ('footprinting') or by two kinds of interference assays: a missing thymine site (MT-site) experiment and a missing thymine methyl site (MTM-site) experiment.

An Update: Enzymatic Synthesis for Industrial Applications

open access: yesAngewandte Chemie International Edition, EarlyView.
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Ginsenoside Rd Attenuates DNA Damage by Increasing Expression of DNA Glycosylase Endonuclease VIII-like Proteins after Focal Cerebral Ischemia

open access: yesChinese Medical Journal, 2016
Background: Ginsenoside Rd (GSRd), one of the main active ingredients in traditional Chinese herbal Panax ginseng, has been found to have therapeutic effects on ischemic stroke.

Excision of damaged bases from transcription intermediates by FPG/NEI superfamily DNA glycosylases [PDF]

open access: yes, 2007
Oxidative lesions are abundant due to constant presence of reactive oxygen species in living cells. Repair of oxidative base lesions is initiated by DNA glycosylases.

A universal framework to efficiently share material and process resources in the DNA construction world [PDF]

open access: yesarXiv, 2021
DNA constructs and their annotated sequence maps have been rapidly accumulating with the advancement of DNA cloning, synthesis, and assembly methods. Such a resource has the potential to be optimally utilized in an autonomous DNA building platform. However, most DNA design processes today remain manually operated with the assistance of graphical user ...

ATP-Stimulated, DNA-Mediated Redox Signaling by XPD, a DNA Repair and Transcription Helicase [PDF]

open access: yes, 2011
Using DNA-modified electrodes, we show DNA-mediated signaling by XPD, a helicase that contains a [4Fe-4S] cluster and is critical for nucleotide excision repair and transcription.

Frameshift Mutagenesis and Microsatellite Instability Induced by Human Alkyladenine DNA Glycosylase [PDF]

open access: yes, 2009
Human alkyladenine DNA glycosylase (hAAG) excises alkylated purines, hypoxanthine, and etheno bases from DNA to form abasic (AP) sites. Surprisingly, elevated expression of hAAG increases spontaneous frameshift mutagenesis. By random mutagenesis of eight
