Polymerase Mu Is a DNA-Directed DNA/RNA Polymerase [PDF]

open access: greenMolecular and Cellular Biology, 2003
DNA polymerases are defined as such because they use deoxynucleotides instead of ribonucleotides with high specificity. We show here that polymerase mu (pol μ), implicated in the nonhomologous end-joining pathway for repair of DNA double-strand breaks, incorporates both ribonucleotides and deoxynucleotides in a template-directed manner.

On the Binding of Rifampicin to the DNA‐Directed RNA Polymerase from Escherichia coli [PDF]

open access: bronzeEuropean Journal of Biochemistry, 1973
The capacity of RNA polymerase to bind the antibiotic rifampicin is rather sensitive to conditions which lead to conformational changes in the enzyme. Repeated freezing and thawing in 1 M LiCl as well as treatment with guanidinium chloride destroys the binding affinity of the enzyme for the inhibitor. Similarly rifampicin does not associate with any of

DragonRNA: Generality of DNA-primed RNA-extension activities by DNA-directed RNA polymerases. [PDF]

open access: yesNucleic Acids Res
Abstract RNA polymerases (RNAPs) transcribe DNA into RNA. Several RNAPs, including from bacteriophages Sp6 and T7, Escherichia coli, and wheat germ, had been shown to add ribonucleotides to DNA 3′ ends. Mitochondria have their own RNAPs (mtRNAPs).

Mode of inhibition of HIV-1 reverse transcriptase by polyacetylenetriol, a novel inhibitor of RNA- and DNA-directed DNA polymerases [PDF]

open access: greenBiochemical Journal, 2002
Polyacetylenetriol (PAT), a natural marine product from the Mediterranean sea sponge Petrosia sp., was found to be a novel general potent inhibitor of DNA polymerases. It inhibits equally well the RNA- and DNA-dependent DNA polymerase activities of retroviral reverse transcriptases (RTs) (i.e.

DNA-directed termination of mammalian RNA polymerase II

open access: goldGenes & Development
ABSTRACTThe best-studied mechanism of eukaryotic RNA polymerase II (RNAPII) transcriptional termination involves polyadenylation site-directed cleavage of the nascent RNA. The RNAPII-associated cleavage product is then degraded by XRN2, dislodging RNAPII from the DNA template.

In silico Evaluation of the Potential of Natural Products from Chili Pepper as Antiviral Agents Against Dna-Directed Rna Polymerase of the Monkeypox Virus

open access: goldBitlis Eren Üniversitesi Fen Bilimleri Dergisi
This study focused on the discovery of new drug candidates effective against the monkeypox virus. Virtual screening was performed to evaluate the potential of chili pepper natural products against homology-modeled DNA-directed RNA polymerase of the monkeypox virus using molecular docking. Our findings revealed that structurally similar triterpenes such

DNA-directed termination of RNA polymerase II transcription [PDF]

open access: yesMolecular Cell, 2023
RNA polymerase II (RNAPII) transcription involves initiation from a promoter, transcriptional elongation through the gene, and termination in the terminator region. In bacteria, terminators often contain specific DNA elements provoking polymerase dissociation, but RNAPII transcription termination is thought to be driven entirely by protein co-factors ...
