Multiple effects of silymarin on the hepatitis C virus lifecycle [PDF]
, 2010 Silymarin, an extract from milk thistle (Silybum marianum), and its purified flavonolignans have been recently shown to inhibit hepatitis C virus (HCV) infection, both in vitro and in vivo.

Inhibitors of an RNA‐dependent DNA polymerase [PDF]
FEBS Letters, 1971 Much interest of late has centered around RNAdirected DNA synthesis. Initially, with the finding of an RNA-dependent DNA polymerase in oncogenic RNA viruses [l-S] and what was described as the exclusive presence of the polymerase in acute leukemia cells as opposed to ‘normal’ cells [6] , speculation as to a molecular basis for leukemogenesis and a ...

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.

Space constrained homology modelling: The paradigm of the RNA-dependent RNA polymerase of dengue (Type II) virus [PDF]
, 2013 Protein structure is more conserved than sequence in nature. In this direction we developed a novel methodology that significantly improves conventional homology modelling when sequence identity is low, by taking into consideration 3D structural features

NeoRdRp2 with improved seed data, annotations, and scoring
Frontiers in VirologyRNA-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 ...

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.

A link between transcription fidelity and pausing in vivo [PDF]
, 2017 Pausing by RNA polymerase is a major mechanism that regulates transcription elongation but can cause conflicts with fellow RNA polymerases and other cellular machineries. Here, we summarize our recent finding that misincorporation could be a major source

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)

Mechanistic insights into the transcriptional arrest in the presence of Double Strand Breaks [PDF]
, 2014 Double-strand breaks (DSBs) occur frequently in the genome during genome replication or by DNA damaging agents. DNA lesions affect fundamental DNA-dependent nuclear processes, such as replication and transcription.

Involvement of the N-terminal portion of influenza virus RNA polymerase subunit PB1 in nucleotide recognition [PDF]
, 2014 The influenza virus PB1 protein functions as a catalytic subunit of the viral RNA-dependent RNA polymerase and contains the highly conserved motifs of RNA-dependent RNA polymerases together with putative nucleotide-binding sites.
