Single-peptide DNA-dependent RNA polymerase homologous to multi-subunit RNA polymerase [PDF]

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-

Poliovirus-specific primer-dependent RNA polymerase able to copy poly(A) [PDF]

open access: green, 1977
A template-dependent RNA polymerase has been isolated from poliovirus-infected cells by assaying for the ability of the enzyme to copy poly(A) complexed to an oligo(U) primer.

Amplification of RNA by an RNA polymerase ribozyme [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance Darwinian life requires the ability to replicate genotypes and express phenotypes. Although all extant life relies on protein enzymes to accomplish these tasks, life in the ancestral RNA world would have used only RNA enzymes. Here, we report the in vitro evolution of an improved RNA polymerase ribozyme that is able to synthesize

Architecture of the spinach plastid-encoded RNA polymerase. [PDF]

open access: yesNat Commun
The plastid-encoded RNA polymerase serves as the principal transcription machinery within chloroplasts, transcribing over 80% of all primary plastid transcripts.

The architecture of RNA polymerase fidelity [PDF]

open access: yesBMC Biology, 2010
The basis for transcriptional fidelity by RNA polymerase is not understood, but the 'trigger loop', a conserved structural element that is rearranged in the presence of correct substrate nucleotides, is thought to be critical.

Suppression by RNA Polymerase I Inhibitors Varies Greatly Between Distinct RNA Polymerase I Transcribed Genes in Malaria Parasites. [PDF]

open access: yesPathogens
The transcription of ribosomal RNA (rRNA) by RNA Polymerase I (Pol I) is the rate-limiting step in ribosome biogenesis and a major determinant of cellular growth rates.

Structural Biology of Bacterial RNA Polymerase

open access: yesBiomolecules, 2015
Since its discovery and characterization in the early 1960s (Hurwitz, J. The discovery of RNA polymerase. J. Biol. Chem. 2005, 280, 42477–42485), an enormous amount of biochemical, biophysical and genetic data has been collected on bacterial RNA ...

Evolution of complex RNA polymerases: the complete archaeal RNA polymerase structure.

open access: yesPLoS Biology, 2009
The archaeal RNA polymerase (RNAP) shares structural similarities with eukaryotic RNAP II but requires a reduced subset of general transcription factors for promoter-dependent initiation.

Structural basis of RNA polymerase complexes in African swine fever virus. [PDF]

open access: yesNat Commun
African swine fever virus is highly contagious and causes a fatal infectious disease in pigs, resulting in a significant global impact on pork supply.

Abstract P-23: Histone N-terminal Tails Reduce Early Nucleosomal Pausing during Transcription [PDF]

open access: yesInternational Journal of Biomedicine, 2021
Background: Nucleosomes are the barriers to transcript elongation by RNA polymerase 2 (Pol 2) in vitro and in vivo. Formation and overcoming the barrier are important for transcription regulation. N-terminal tails of core histones do not affect the inner
