Uptake of amino acids and nucleic acid precursors by regenerating rat liver [PDF]

Biochemical Journal, 1972
1. At 0.5–1.0h after partial hepatectomy the intracellular acid-soluble fraction of rat liver took up twice as much radioactivity from [3H]orotic acid, [3H]uridine and [3H]thymidine as did similar fractions from sham-operated animals. This increase in penetration was not prevented by adrenalectomy or actinomycin, both of which decreased precursor ...

Bacteriophage Assembly

Viruses, 2011
Bacteriophages have been a model system to study assembly processes for over half a century. Formation of infectious phage particles involves specific protein-protein and protein-nucleic acid interactions, as well as large conformational changes of ...

An all-purine precursor of nucleic acids. [PDF]

Proceedings of the National Academy of Sciences, 1988
The theory is proposed that the pyrimidines in extant nucleic acids are postenzymatic substitutes for their isoelectronic and isogeometric position 3-bonded purine analogs xanthine and isoguanine, which were sibling products in a preenzymatic de novo purine pathway.

Translin facilitates RNA polymerase II dissociation and suppresses genome instability during RNase H2- and Dicer-deficiency.

PLoS Genetics, 2022
The conserved nucleic acid binding protein Translin contributes to numerous facets of mammalian biology and genetic diseases. It was first identified as a binder of cancer-associated chromosomal translocation breakpoint junctions leading to the ...

Diversity of Endonuclease V: From DNA Repair to RNA Editing

Biomolecules, 2015
Deamination of adenine occurs in DNA, RNA, and their precursors via a hydrolytic reaction and a nitrosative reaction. The generated deaminated products are potentially mutagenic because of their structural similarity to natural bases, which in turn leads
