Biogenesis of Iron–Sulfur Clusters and Their Role in DNA Metabolism

Frontiers in Cell and Developmental Biology, 2021
Iron–sulfur (Fe/S) clusters (ISCs) are redox-active protein cofactors that their synthesis, transfer, and insertion into target proteins require many components. Mitochondrial ISC assembly is the foundation of all cellular ISCs in eukaryotic cells.

Cyclization of Short DNA Fragments [PDF]

Physica A482, 569 (2017), 2017
From the per unit length free energy for DNA under tension, we have calculated an effective contour length dependent persistence length for short DNA. This effective persistence length results from the enhanced fluctuations in short DNA. It decreases for shorter DNA, making shorter DNA more flexible.

DNA binding shifts the redox potential of the transcription factor SoxR [PDF]

, 2008
Electrochemistry measurements on DNA-modified electrodes are used to probe the effects of binding to DNA on the redox potential of SoxR, a transcription factor that contains a [2Fe-2S] cluster and is activated through oxidation. A DNA-bound potential of +

The trajectory of intrahelical lesion recognition and extrusion by the human 8-oxoguanine DNA glycosylase

Nature Communications, 2020
DNA glycosylases are lesion-specific enzymes that recognize specific nucleobase damages and catalyze their excision through cleavage of the glycosidic bond.

Defects Can Increase the Melting Temperature of DNA-Nanoparticle Assemblies [PDF]

J. Phys. Chem. B, 110 (2006) 16393-16396, 2007
DNA-gold nanoparticle assemblies have shown promise as an alternative technology to DNA microarrays for DNA detection and RNA profiling. Understanding the effect of DNA sequences on the melting temperature of the system is central to developing reliable detection technology.

DNA demethylation by ROS1a in rice vegetative cells promotes methylation in sperm. [PDF]

, 2019
Epigenetic reprogramming is required for proper regulation of gene expression in eukaryotic organisms. In Arabidopsis, active DNA demethylation is crucial for seed viability, pollen function, and successful reproduction. The DEMETER (DME) DNA glycosylase

Modulation of the Turnover of Formamidopyrimidine DNA Glycosylase [PDF]

Biochemistry, 2006
In recent years, significant progress has been made in determining the catalytic mechanisms by which base excision repair (BER) DNA glycosylases and glycosylase-abasic site (AP) lyases cleave the glycosyl bond. While these investigations have identified active site residues and active site architectures, few investigations have analyzed postincision ...

DNA glycosylases involved in base excision repair may be associated with cancer risk in BRCA1 and BRCA2 mutation carriers. [PDF]

PLoS Genetics, 2014
Single Nucleotide Polymorphisms (SNPs) in genes involved in the DNA Base Excision Repair (BER) pathway could be associated with cancer risk in carriers of mutations in the high-penetrance susceptibility genes BRCA1 and BRCA2, given the relation of ...

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

Angewandte 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 ...

Active DNA Demethylation Mediated by DNA Glycosylases [PDF]

Annual Review of Genetics, 2009
Active DNA demethylation is involved in many vital developmental and physiological processes of plants and animals. Recent genetic and biochemical studies in Arabidopsis have demonstrated that a subfamily of DNA glycosylases function to promote DNA demethylation through a base excision-repair pathway.
