Origin and Evolution of RNA-Dependent RNA Polymerase [PDF]

open access: yesFrontiers in Genetics, 2017
RNA-dependent RNA polymerases (RdRp) are very ancient enzymes and are essential for all viruses with RNA genomes. We reconstruct the origin and evolution of this polymerase since the initial stages of the origin of life. The origin of the RdRp was traced

Reticulocyte RNA-Dependent RNA Polymerase [PDF]

open access: yesProceedings of the National Academy of Sciences, 1973
A cytoplasmic, microsomal bound RNA-dependent RNA polymerase has been purified 2500-fold from rabbit reticulocyte lysates. The synthesis of RNA with the purified enzyme is absolutely dependent on the addition of an RNA template. The best template is hemoglobin messenger RNA, while bacteriophage RNA and poly(A,G) are less active, and DNA is completely ...

The Rna-Dependent RNA Polymerase of the Influenza a Virus [PDF]

open access: yesFuture Virology, 2014
The influenza A virus causes a highly contagious respiratory disease that significantly impacts our economy and health. Its replication and transcription is catalyzed by the viral RNA polymerase. This enzyme is also crucial for the virus, because it is involved in the adaptation of zoonotic strains.

Inhibitors of an RNA‐dependent DNA polymerase [PDF]

open access: yesFEBS Letters, 1971
Much interest of late has centered around RNAdirected DNA synthesis. Initially, with the finding of an RNA-dependent DNA polymerase in oncogenic RNA viruses [l-S] and what was described as the exclusive presence of the polymerase in acute leukemia cells as opposed to ‘normal’ cells [6] , speculation as to a molecular basis for leukemogenesis and a ...

Baicalein and Baicalin Inhibit SARS-CoV-2 RNA-Dependent-RNA Polymerase

open access: yesMicroorganisms, 2021
Coronavirus Disease 2019 (COVID-19) is a deadly emerging infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Because SARS-CoV-2 is easily transmitted through the air and has a relatively long incubation time, COVID ...

Structural bases of norovirus RNA dependent RNA polymerase inhibition by novel suramin-related compounds. [PDF]

open access: yesPLoS ONE, 2014
Noroviruses (NV) are +ssRNA viruses responsible for severe gastroenteritis; no effective vaccines/antivirals are currently available. We previously identified Suramin (9) as a potent inhibitor of NV-RNA dependent RNA polymerase (NV-RdRp).

RNA-dependent RNA polymerase of tobacco plants [PDF]

open access: yesProceedings of the National Academy of Sciences, 1978
Several properties of RNA polymerase (nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6) active fractions obtained from tobacco plants, be they uninfected, infected with tobacco mosaic virus, or infected with tobacco necrosis virus, were compared.

Seeking antiviral drugs to inhibit SARS-CoV-2 RNA dependent RNA polymerase: A molecular docking analysis

open access: yesPLoS ONE, 2022
COVID-19 outbreak associated with the severe acute respiratory syndrome coronavirus (SARS-CoV-2) raised health concerns across the globe and has been considered highly transmissible between people.

Molecular Evolution of RNA-Dependent RNA Polymerase Region in Norovirus Genogroup I

open access: yesViruses, 2023
Norovirus is the leading viral agent of gastroenteritis in humans. RNA-dependent RNA polymerase (RdRp) is essential in the replication of norovirus RNA. Here, we present a comprehensive evolutionary analysis of the norovirus GI RdRp gene.

Structure of the RNA-dependent RNA polymerase of poliovirus [PDF]

open access: yesStructure, 1997
The central player in the replication of RNA viruses is the viral RNA-dependent RNA polymerase. The 53 kDa poliovirus polymerase, together with other viral and possibly host proteins, carries out viral RNA replication in the host cell cytoplasm. RNA-dependent RNA polymerases comprise a distinct category of polymerases that have limited sequence ...
