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 ...

International Journal of Molecular Sciences, 2019 Maintenance of genome integrity is a key process in all organisms. DNA polymerases (Pols) are central players in this process as they are in charge of the faithful reproduction of the genetic information, as well as of DNA repair. Interestingly, all eukaryotes possess a large repertoire of polymerases.

Beyond the Lesion: Back to High Fidelity DNA Synthesis
Frontiers in Molecular Biosciences, 2022 High fidelity (HiFi) DNA polymerases (Pols) perform the bulk of DNA synthesis required to duplicate genomes in all forms of life. Their structural features, enzymatic mechanisms, and inherent properties are well-described over several decades of research.

Functional Insights into ANP32A-Dependent Influenza A Virus Polymerase Host Restriction
Cell Reports, 2017 Host restriction of influenza A virus limits pandemic emergence. The viral RNA polymerase (vPol) is an essential enzyme that must adapt for avian viruses to replicate in humans. Species differences in host ANP32A dictate adaptation: human ANP32A lacks an

Kinetic analysis of an efficient DNA-dependent TNA polymerase. [PDF]
, 2005 alpha-l-Threofuranosyl nucleoside triphosphates (tNTPs) are tetrafuranose nucleoside derivatives and potential progenitors of present-day beta-d-2'-deoxyribofuranosyl nucleoside triphosphates (dNTPs).

LigD: A Structural Guide to the Multi-Tool of Bacterial Non-Homologous End Joining
Frontiers in Molecular Biosciences, 2021 DNA double-strand breaks are the most lethal form of damage for living organisms. The non-homologous end joining (NHEJ) pathway can repair these breaks without the use of a DNA template, making it a critical repair mechanism when DNA is not replicating ...

Recombinant GII.Pe-GII.4 Norovirus, Thailand, 2017–2018
Emerging Infectious Diseases, 2019 During June 2017–December 2018, norovirus was responsible for 10.9% of acute gastroenteritis cases in Thailand. Genogroup I (GI) was found in 14% of samples, of which 12 were co-infected with genogroup II (GII).

, 2011 Viral polymerases play a central role in viral genome replication and transcription. Based on the genome type and the specific needs of particular virus, RNA-dependent RNA polymerase, RNA-dependent DNA polymerase, DNA-dependent RNA polymerase, and DNA-dependent RNA polymerases are found in various viruses.

Structure and mechanism of human DNA polymerase η [PDF]
, 2010 The variant form of the human syndrome xeroderma pigmentosum (XPV) is caused by a deficiency in DNA polymerase eta (Pol eta), a DNA polymerase that enables replication through ultraviolet-induced pyrimidine dimers.
