Increased tRNA modification and gene-specific codon usage regulate cell cycle progression during the DNA damage response [PDF]

open access: yes, 2012
S-phase and DNA damage promote increased ribonucleotide reductase (RNR) activity. Translation of RNR1 has been linked to the wobble uridine modifying enzyme tRNA methyltransferase 9 (Trm9).

Identification of a novel methyltransferase, Bmt2, responsible for the N-1-methyl-adenosine base modification of 25S rRNA in "Saccharomyces cerevisiae" [PDF]

open access: yes, 2013
The 25S rRNA of yeast contains several base modifications in the functionally important regions. The enzymes responsible for most of these base modifications remained unknown.

Purine and pyrimidine antagonism in a pyrimidine-deficient mutant of Neurospora [PDF]

open access: yes, 1948
The present study is concerned with the inhibition of growth of the pyrimidine-deficient Neurospora mutant, No. 1298, by the naturally occurring purine ribonucleotides and ribonucleosides.

Дослідження взаємодії манітолу з нуклеозидами за допомогою флуоресцентного зонда [PDF]

open access: yes, 2017
Досліджено взаємодію рибонуклеозидів (РН) з манітолом за допомогою флуоресцентного зонда. Встановлено, що при титруванні тестового барвника зростаючими концентраціями розчинів РН та комплексу РН з манітолом (РНМ) зменшується інтенсивність флуоресценції ...

Salvage enzymes in nucleotide biosynthesis [PDF]

open access: yes, 2007
Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

Abiotic Ribonucleoside Formation in Aqueous Microdroplets: Mechanistic Exploration, Acidity, and Electric Field Effects

open access: yesChemistryEurope
Aqueous microdroplets have been reported to dramatically increase the rate of chemical reactions. Proposed mechanisms for this acceleration include confinement effects upon droplet evaporation, and Brønsted acid or electric field catalysis at the air ...
