Inspection on the Mechanism of SARS-CoV-2 Inhibition by Penciclovir: A Molecular Dynamic Study

open access: yesMolecules, 2022
In recent years, humanity has had to face a critical pandemic due to SARS-CoV-2. In the rapid search for effective drugs against this RNA-positive virus, the repurposing of already existing nucleotide/nucleoside analogs able to stop RNA replication by ...

Generation and characterization of a recombinant Rift Valley fever virus expressing a V5 epitope-tagged RNA-dependent RNA polymerase [PDF]

open access: yes, 2011
The viral RNA-dependent RNA polymerase (RdRp; L protein) of Rift Valley fever virus (RVFV; family Bunyaviridae) is a 238 kDa protein that is crucial for the life cycle of the virus, as it catalyses both transcription of viral mRNAs and replication of the

Global Genomic Analysis of SARS-CoV-2 RNA Dependent RNA Polymerase Evolution and Antiviral Drug Resistance

open access: yesMicroorganisms, 2021
A variety of antiviral treatments for COVID-19 have been investigated, involving many repurposed drugs. Currently, the SARS-CoV-2 RNA-dependent RNA polymerase (RdRp, encoded by nsp12-nsp7-nsp8) has been targeted by numerous inhibitors, e.g., remdesivir ...

A splicing-dependent transcriptional checkpoint associated with prespliceosome formation [PDF]

open access: yes, 2014
There is good evidence for functional interactions between splicing and transcription in eukaryotes, but how and why these processes are coupled remain unknown.

RNA-dependent RNA Polymerase Assay for Hepatitis E Virus

open access: yesBio-Protocol, 2017
RNA-dependent RNA polymerase (RdRp) is essential for the replication of viral RNA for RNA viruses. It synthesizes the complementary strand of viral genomic RNA, which is used subsequently as a template to generate more copies of viral genome.

Ribovirus classification by a polymerase barcode sequence [PDF]

open access: yesPeerJ, 2022
RNA viruses encoding a polymerase gene (riboviruses) dominate the known eukaryotic virome. High-throughput sequencing is revealing a wealth of new riboviruses known only from sequence, precluding classification by traditional taxonomic methods.

Single-peptide DNA-dependent RNA polymerase homologous to multi-subunit RNA polymerase

open access: yesNature 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-

Independent Inhibition of the Polymerase and Deubiquitinase Activities of the Crimean–Congo Hemorrhagic Fever Virus Full-Length L-Protein

open access: yesProceedings, 2020
The Crimean–Congo hemorrhagic fever virus (CCHFV) is a segmented negative-sense RNA virus that can cause severe human disease. The World Health Organization (WHO) has listed CCHFV as a priority pathogen with an urgent need for enhanced research ...

Activation of influenza virus RNA polymerase by the 5' and 3' terminal duplex of genomic RNA [PDF]

open access: yes, 2003
The current model for influenza virus mRNA transcription involves the sequential interaction of the viral polymerase with the 5'- and 3'-ends of vRNA, with each RNA-protein interaction triggering a polymerase function necessary for cap-primed ...

PAPD5, a noncanonical poly(A) polymerase with an unusual RNA-binding motif [PDF]

open access: yes, 2011
PAPD5 is one of the seven members of the family of noncanonical poly(A) polymerases in human cells. PAPD5 was shown to polyadenylate aberrant pre-ribosomal RNAs in vivo, similar to degradation-mediating polyadenylation by the noncanonical poly(A ...
