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

Single-peptide DNA-dependent RNA polymerase homologous to multi-subunit RNA polymerase [PDF]
Nature Communications, 2017 Although all known RNA polymerases have multiple subunits, unrelated single-subunit polymerases have also been described. Here, the authors describe a single-subunit RNA polymerase from the SPβ prophage ofBacillus subtilis, which shares homology to multi-

Baicalein and Baicalin Inhibit SARS-CoV-2 RNA-Dependent-RNA Polymerase
Microorganisms, 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 ...

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

Identification of Benzothiophene-Derived Inhibitors of Flaviviruses by Targeting RNA-Dependent RNA Polymerase [PDF]
VirusesFlaviviruses such as Dengue, West Nile, and Zika viruses are mosquito-borne RNA viruses that can cause serious diseases in humans. To develop effective drugs for treating these viruses’ infections, we create a new approach for developing common or shared
