Identification of an ortholog of the eukaryotic RNA polymerase III subunit RPC34 in Crenarchaeota and Thaumarchaeota suggests specialization of RNA polymerases for coding and non-coding RNAs in Archaea. [PDF]

, 2009
Contains fulltext : 80405.pdf (Publisher’s version ) (Open Access)One of the hallmarks of eukaryotic information processing is the co-existence of 3 distinct, multi-subunit RNA polymerase complexes that are dedicated to the ...

The RNA silencing enzyme RNA polymerase v is required for plant immunity. [PDF]

PLoS Genetics, 2011
RNA-directed DNA methylation (RdDM) is an epigenetic control mechanism driven by small interfering RNAs (siRNAs) that influence gene function. In plants, little is known of the involvement of the RdDM pathway in regulating traits related to immune ...

Primer Extension Reactions for the PCR- based α- complementation Assay

Bio-Protocol, 2015
The PCR- based- α- complementation assay is an effective technique to measure the fidelity of polymerases, especially RNA-dependent RNA polymerases (RDRP) and Reverse Transcriptases (RT). It has been successfully employed to determine the fidelity of the

Functional Diversification of Maize RNA Polymerase IV and V Subtypes via Alternative Catalytic Subunits

Cell Reports, 2014
Summary: Unlike nuclear multisubunit RNA polymerases I, II, and III, whose subunit compositions are conserved throughout eukaryotes, plant RNA polymerases IV and V are nonessential, Pol II-related enzymes whose subunit compositions are still evolving ...

In Silico Analysis of Honey Bee Peptides as Potential Inhibitors of Capripoxvirus DNA-Directed RNA Polymerase

Animals, 2023
The genus Capripoxvirus belongs to the Poxviridae family. The sheeppox, goatpox, and lumpy skin disease viruses are three species of this genus with 96% identity in their genomes. These are financially devastating viral infections among cattle, which cause a reduction in animal products and lead to a loss in livestock industries.

Topoisomerase IIα promotes activation of RNA polymerase I transcription by facilitating pre-initiation complex formation [PDF]

, 2013
Type II DNA topoisomerases catalyse DNA double-strand cleavage, passage and re-ligation to effect topological changes. There is considerable interest in elucidating topoisomerase II roles, particularly as these proteins are targets for anti-cancer drugs.

Simultaneous Disruption of Two DNA Polymerases, Pol eta and Pol zeta, in Avian DT40 Cells Unmasks the Role of Pol eta in Cellular Response to Various DNA Lesions [PDF]

, 2010
Replicative DNA polymerases are frequently stalled by DNA lesions. The resulting replication blockage is released by homologous recombination (HR) and translesion DNA synthesis (TLS). TLS employs specialized TLS polymerases to bypass DNA lesions.

DNA-directed DNA Polymerase Activity in Oncogenic RNA Viruses

Nature, 1970
Besides having RNA-dependent DNA polymerase activity, oncogenic RNA viruses possess a DNA-directed DNA polymerase which is distinguished from previously described enzymes of this type in preferring double-stranded DNA as template and yielding a principally double-stranded product.

Inhibition of Ebola Virus by Anti-Ebola miRNAs in silico

Journal of Infection in Developing Countries, 2016
Introduction: MicroRNAs (miRNAs) are small, noncoding RNA molecules that regulate transcriptional and posttranscriptional gene regulation of the organisms. miRNA provides immune defense when the body is faced with challenges intracellular agents.

Isolation and physical properties of the DNA‐directed RNA polymerase from Thermus thermophilus HB8 [PDF]

European Journal of Biochemistry, 1990
The DNA‐directed RNA polymerase from the extremely thermophilic eubacterium Thermus thermophilus HB8 was purified employing a new and rapid method. The subunit pattern of the enzyme, analyzed by SDS gel electrophoresis, was interpreted as: 140 kDa and 170 kDa for β and β′, 40 kDa for α and 92 kDa for ó.
