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

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]
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 ...
