The architecture of RNA polymerase fidelity [PDF]
BMC 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.

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

RNA Polymerases of Maize: Nuclear RNA Polymerases [PDF]
Proceedings of the National Academy of Sciences, 1971 Two DNA-dependent RNA polymerases of nuclear origin have been purified from leaves of Zea mays . The two enzymes can be separated on DEAE-cellulose columns. Enzymes I and II are eluted with 0.08 and 0.20 M (NH 4 ) 2 SO 4 , respectively.

DNA polymerase III protein, HolC, helps resolve replication/transcription conflicts
Microbial Cell, 2021 In Escherichia coli, DNA replication is catalyzed by an assembly of proteins, the DNA polymerase III holoenzyme. This complex includes the polymerase and proofreading subunits, the processivity clamp and clamp loader complex.

Biophysical Chemistry, 2011 Molecular motors can exhibit Brownian ratchet or power stroke mechanisms. These mechanistic categories are related to transition state position: An early transition state suggests that chemical energy is stored and then released during the step (stroke) while a late transition state suggests that the release of chemical energy rectifies thermally ...

Cell, 1999 The appearance of these structures represents a historic advance in our understanding of one of molecular biology's most remarkable enzymes. Here we have suggested several possible structural bases for key steps in its function. Although speculative, they should serve as stimuli for future work.

Structure of the SARS-CoV-2 RNA-dependent RNA polymerase in the presence of favipiravir-RTP
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance While the current COVID-19 pandemic continues, the US Food and Drug Administration (FDA) has approved only one drug against the virus—remdesivir.

bioRxiv, 2020 The pandemic of Corona Virus Disease 2019 (COVID-19) caused by SARS-CoV-2 has become a global crisis. The replication of SARS-CoV-2 requires the viral RNA-dependent RNA polymerase (RdRp), a direct target of the antiviral drug, Remdesivir.

Emerging SARS-CoV-2 mutation hot spots include a novel RNA-dependent-RNA polymerase variant
Journal of Translational Medicine, 2020 Background SARS-CoV-2 is a RNA coronavirus responsible for the pandemic of the Severe Acute Respiratory Syndrome (COVID-19). RNA viruses are characterized by a high mutation rate, up to a million times higher than that of their hosts.
