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

open access: yesFrontiers 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 ...

Topoisomerase IIα promotes activation of RNA polymerase I transcription by facilitating pre-initiation complex formation [PDF]

open access: yes, 2013
Type II DNA topoisomerases catalyse DNA double-strand cleavage, passage and re-ligation to effect topological changes. There is considerable interest in elucidating topoisomerase II roles, particularly as these proteins are targets for anti-cancer drugs.

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 ...

Crystal structure of Zika virus NS5 RNA-dependent RNA polymerase

open access: yesNature 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

open access: yesViruses, 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.

A hepatitis C virus cis-acting replication element forms a long-range RNA-RNA interaction with upstream RNA sequences in NS5B [PDF]

open access: yes, 2008
The genome of hepatitis C virus (HCV) contains cis-acting replication elements (CREs) comprised of RNA stem-loop structures located in both the 5' and 3' non-coding regions (NCR), and in the NS5B coding sequence.

An improved method for surface immobilisation of RNA: application to small Non-Coding RNA - mRNA pairing [PDF]

open access: yes, 2013
Characterisation of RNA and its intermolecular interactions is increasing in importance as the inventory of known RNA functions continues to expand. RNA-RNA interactions are central to post-transcriptional gene regulation mechanisms in bacteria, and the ...

Identification of an ortholog of the eukaryotic RNA polymerase III subunit RPC34 in Crenarchaeota and Thaumarchaeota suggests specialization of RNA polymerases for coding and non-coding RNAs in Archaea. [PDF]

open access: yes, 2009
Contains fulltext : 80405.pdf (Publisher’s version ) (Open Access)One of the hallmarks of eukaryotic information processing is the co-existence of 3 distinct, multi-subunit RNA polymerase complexes that are dedicated to the ...

Roles of the HEAT repeat proteins Utp10 and Utp20 in 40S ribosome maturation [PDF]

open access: yes, 2007
A family of HEAT-repeat containing ribosome synthesis factors was previously identified in Saccharomyces cerevisiae. We report the detailed characterization of two of these factors, Utp10 and Utp20, which were initially identified as components of the ...

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

open access: yesVirology 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.
