Current Opinion in Structural Biology, 2009 The recently solved X-ray crystal structures of archaeal RNA polymerase (RNAP) allow a structural comparison of the transcription machinery among all three domains of life. Archaeal transcription is very simple and all components, including the structures of general transcription factors and RNAP, are highly conserved in eukaryotes. Therefore, it could

Amplification of RNA by an RNA polymerase ribozyme [PDF]
Proceedings 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

RNA Unwinding by the Trf4/Air2/Mtr4 Polyadenylation (TRAMP) Complex [PDF]
, 2012 Many RNA-processing events in the cell nucleus involve the Trf4/Air2/Mtr4 polyadenylation (TRAMP) complex, which contains the poly(A) polymerase Trf4p, the Zn-knuckle protein Air2p, and the RNA helicase Mtr4p.

RNA-Dependent RNA Polymerase as a Target for COVID-19 Drug Discovery
SLAS Discovery, 2020 COVID-19 respiratory disease caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has rapidly become a global health issue since it emerged in December 2019.

Mathematical Biosciences and Engineering, 2019 In the classical chemostat, the output of the system has no effect on its input. This contrasts with many ecological systems, where the output at the end of a growing season affects nutrient inputs for subsequent seasons.

A comparative study of DNA-dependent RNA polymerases from rat ascites hepatoma cell nuclei and from rat liver nuclei [PDF]
, 1975 DNA-dependent RNA polymerases (EC 2.7.7.6) were extracted and partially purified form the nuclei of rat ascites hepatoma cells (AH-130) induced by 4-dimethylaminoazobenzene.

Regulation of Eukaryotic RNAPs Activities by Phosphorylation
Frontiers in Molecular Biosciences, 2021 Evolutionarily conserved kinases and phosphatases regulate RNA polymerase II (RNAPII) transcript synthesis by modifying the phosphorylation status of the carboxyl-terminal domain (CTD) of Rpb1, the largest subunit of RNAPII.

Nucleolar RNA polymerase II drives ribosome biogenesis
Nature, 2020 Proteins are manufactured by ribosomes—macromolecular complexes of protein and RNA molecules that are assembled within major nuclear compartments called nucleoli 1 , 2 .

RNA Polymerase III, Ageing and Longevity
Frontiers in Genetics, 2021 Transcription in eukaryotic cells is performed by three RNA polymerases. RNA polymerase I synthesises most rRNAs, whilst RNA polymerase II transcribes all mRNAs and many non-coding RNAs. The largest of the three polymerases is RNA polymerase III (Pol III)

Nucleocapsid protein of SARS-CoV-2 phase separates into RNA-rich polymerase-containing condensates
Nature Communications, 2020 The etiologic agent of the Covid-19 pandemic is the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The viral membrane of SARS-CoV-2 surrounds a helical nucleocapsid in which the viral genome is encapsulated by the nucleocapsid protein. The
