In vitro RNA-dependent RNA Polymerase Assay Using Arabidopsis RDR6

Bio-Protocol, 2018
RNA-dependent RNA polymerases (RdRPs) in eukaryotes convert single-stranded RNAs into double-stranded RNAs, thereby amplifying small interfering RNAs that play crucial roles in the regulation of development, maintenance of genome integrity and antiviral ...

Identification of Potential Key Agents for Targeting RNA-Dependent RNA Polymerase of SARS-CoV-2 by Integrated Analysis and Virtual Drug Screening

Frontiers in Genetics, 2020
BackgroundRNA-dependent RNA polymerase (RdRp) is the key enzyme responsible for the SARS-CoV-2 replication process and catalyzes the synthesis of complementary minus strand RNA and genomic plus strand RNA, often recognized as good targets for antiviral ...

Crystal structure of Zika virus NS5 RNA-dependent RNA polymerase

Nature Communications, 2017
The Zika virus outbreak is a global health threat and there is an urgent need for drugs against the virus. Here the authors present the structure of the RNA-dependent RNA-polymerase domain from Zika non-structural protein 5, which is a template for the ...

Inhibitors of the Hepatitis C Virus RNA-Dependent RNA Polymerase NS5B

Viruses, 2010
More than 20 years after the identification of the hepatitis C virus (HCV) as a novel human pathogen, the only approved treatment remains a combination of pegylated interferon-α and ribavirin.

Biochemical characterization of the fidelity of poliovirus RNA-dependent RNA polymerase

Virology Journal, 2007
Background Putative high mutation rates of RNA viruses are believed to mediate undesirable phenomena, such as emergence of drug resistance. However, very little is known about biochemical fidelity rates for viral RNA-dependent RNA polymerases.

RNA-dependent RNA polymerases of dsRNA bacteriophages

Virus Research, 2004
Genome replication and transcription of riboviruses are catalyzed by an RNA-dependent RNA polymerase (RdRP). RdRPs are normally associated with other virus- or/and host-encoded proteins that modulate RNA polymerization activity and template specificity. The polymerase complex of double-stranded dsRNA viruses is a large icosahedral particle (inner core)

NeoRdRp2 with improved seed data, annotations, and scoring

Frontiers in Virology
RNA-dependent RNA polymerase (RdRp) is a marker gene for RNA viruses; thus, it is widely used to identify RNA viruses from metatranscriptome data. However, because of the high diversity of RdRp domains, it remains difficult to identify RNA viruses using ...

Targeting Emerging RNA Viruses by Engineered Human Superantibody to Hepatitis C Virus RNA-Dependent RNA Polymerase

Frontiers in Microbiology, 2022
RNA-dependent RNA polymerase (RdRp) is a unique and highly conserved enzyme across all members of the RNA virus superfamilies. Besides, humans do not have a homolog of this protein.
