Stereoselective Synthesis of β-Glycinamide Ribonucleotide

open access: yesMolecules, 2022
A diastereoselective synthesis of the β-anomer of glycinamide ribonucleotide (β-GAR) has been developed. The synthesis was accomplished in nine steps from D-ribose and occurred in 5% overall yield. The route provided material on the multi-milligram scale.

Transforming RNA Degradation into Accurate RNA Detection: RNase I–Assisted Rolling Circle Amplification for Clinical Samples

open access: yesAngewandte Chemie, EarlyView.
Here, we transform this otherwise destructive enzymatic activity into a powerful diagnostic advantage through an RNase I–assisted rolling circle amplification (RI‐RCA) strategy. By integrating controlled RNase I–mediated RNA digestion with circular DNA templates, this approach enables direct and highly sensitive detection of target RNA sequences. Using

Ribonucleotide reductase inhibitors: a new look at an old target for radiosensitization

open access: yesFrontiers in Oncology, 2012
Ribonucleotide reductase, the rate limiting enzyme in the synthesis and repair of DNA, has been studied as a target for inhibition in the treatment of cancer for many years.

Spectroscopic and theoretical approaches for studying radical reactions in class I ribonucleotide reductase [PDF]

open access: yes, 2005
Ribonucleotide reductases (RNRs) catalyze the production of deoxyribonucleotides, which are essential for DNA synthesis and repair in all organisms.

Studying Ribonucleotide Incorporation: Strand-specific Detection of Ribonucleotides in the Yeast Genome and Measuring Ribonucleotide-induced Mutagenesis [PDF]

open access: yesJournal of Visualized Experiments, 2018
The presence of ribonucleotides in nuclear DNA has been shown to be a source of genomic instability. The extent of ribonucleotide incorporation can be assessed by alkaline hydrolysis and gel electrophoresis as RNA is highly susceptible to hydrolysis in alkaline conditions.

The Origin and Evolution of Ribonucleotide Reduction

open access: yesLife, 2015
Ribonucleotide reduction is the only pathway for de novo synthesis of deoxyribonucleotides in extant organisms. This chemically demanding reaction, which proceeds via a carbon-centered free radical, is catalyzed by ribonucleotide reductase (RNR).

Inhibitors of the Cancer Target Ribonucleotide Reductase, Past and Present

open access: yesBiomolecules, 2022
Ribonucleotide reductase (RR) is an essential multi-subunit enzyme found in all living organisms; it catalyzes the rate-limiting step in dNTP synthesis, namely, the conversion of ribonucleoside diphosphates to deoxyribonucleoside diphosphates.

Structural basis for proficient oxidized ribonucleotide insertion in double strand break repair

open access: yesNature Communications, 2021
The authors previously showed that pol μ lacks discrimination against oxidized dGTP (8-oxo-dGTP). Here they reveal the structural basis for proficient oxidized ribonucleotide (8-oxo-rGTP) incorporation during double strand break repair by pol μ.

Gene Therapy Rescues Cardiac Dysfunction in Duchenne Muscular Dystrophy Mice by Elevating Cardiomyocyte Deoxy-Adenosine Triphosphate

open access: yesJACC: Basic to Translational Science, 2019
Summary: Mutations in the gene encoding for dystrophin leads to structural and functional deterioration of cardiomyocytes and is a hallmark of cardiomyopathy in Duchenne muscular dystrophy (DMD) patients.
