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

Frontiers 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

SARS-CoV-2 RNA Dependent RNA polymerase (RdRp) – A drug repurposing study

Heliyon, 2020
The outbreak of SARS-CoV-2 in December 2019 in China subsequently lead to a pandemic. Lack of vaccine and specific anti-viral drugs started a global health disaster. For a sustained control and protection, development of potential anti-viral drugs is one

Structure of the RNA-dependent RNA polymerase P2 from the cystovirus φ8 [PDF]

Scientific Reports
The replication of RNA viruses relies on the activity of RNA-dependent RNA polymerases (RdRps). Despite large variations in their genomic sequences, viral RdRps share a common architecture generally known as a closed right hand.

Reticulocyte RNA-Dependent RNA Polymerase [PDF]

Proceedings 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]

Future 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.
