Defective removal of ribonucleotides from DNA promotes systemic autoimmunity.
Journal of Clinical Investigation, 2015 Genome integrity is continuously challenged by the DNA damage that arises during normal cell metabolism. Biallelic mutations in the genes encoding the genome surveillance enzyme ribonuclease H2 (RNase H2) cause Aicardi-Goutières syndrome (AGS), a ...

PLoS ONE, 2022 Ribonucleotide reductases (RNRs) use radical-based chemistry to catalyze the conversion of all four ribonucleotides to deoxyribonucleotides. The ubiquitous nature of RNRs necessitates multiple RNR classes that differ from each other in terms of the ...

Remote Control of Eukaryotic Gene Expression by a Modular Ultrasound‐Responsive RNA Toolkit
Angewandte Chemie, EarlyView.A modular RNA‐based sonogenetic toolkit enables remote control of gene expression in eukaryotes by releasing small molecule modulators from ultrasound‐responsive carriers. These modulators activate engineered mRNA elements such as riboswitches, leading to tunable protein expression.

The binding of streptomycin to ribonucleotides.
The Journal of Antibiotics, 1979 Incubation of streptomycin (SM) with [32P]5'-ribonucleotides at pH 7.0 produces fractions that migrate towards the cathode in high voltage electrophoresis (HVE) separations at pH 3.5. SM appears to interact with pG, pA and pC but not with pU. The appearance of these [32P]-labeled fractions is dependent on incubation time and SM concentration ...

Lethal Mutagenesis of Picornaviruses with N-6-Modified Purine Nucleoside Analogues [PDF]
, 2008 RNA viruses exhibit extraordinarily high mutation rates during genome replication. Nonnatural ribonucleosides that can increase the mutation rate of RNA viruses by acting as ambiguous substrates during replication have been explored as antiviral agents ...

Etheno adducts: from tRNA modifications to DNA adducts and back to miscoding ribonucleotides
Genes and Environment, 2021 Etheno (and ethano) derivatives of nucleic acid bases have an extra 5-membered ring attached. These were first noted as wyosine bases in tRNAs. Some were fluorescent, and the development of etheno derivatives of adenosine, cytosine, and guanosine led to ...

Increased levels of RNA oxidation enhance the reversion frequency in aging pro-apoptotic yeast mutants [PDF]
, 2016 Despite recent advances in understanding the complexity of RNA processes, regulation of the metabolism of oxidized cellular RNAs and the mechanisms through which oxidized ribonucleotides affect mRNA translation, and consequently cell viability, are not ...

Computational and Structural Biotechnology Journal, 2021 Ribonucleotides (rNTPs) are predicted to be incorporated into the genome at a rate of up to 3 million times per cell division, making rNTPs the most common non-standard nucleotide in the human genome.
