Acceleration of DNA Replication of Klenow Fragment by Small Resisting Force [PDF]

open access: yesChin. Phys. Lett. 2021, 38 (11): 118701, 2021
DNA polymerases are an essential class of enzymes or molecular motors that catalyze processive DNA syntheses during DNA replications. A critical issue for DNA polymerases is their molecular mechanism of processive DNA replication. We have previously proposed a model for chemomechanical coupling of DNA polymerases, based on which the predicted results ...

Density- and elongation speed-dependent error correction in RNA polymerization [PDF]

open access: yes, 2021
Backtracking of RNA polymerase (RNAP) is an important pausing mechanism during DNA transcription that is part of the error correction process that enhances transcription fidelity. We model the backtracking mechanism of RNA polymerase, which usually happens when the polymerase tries to incorporate a mismatched nucleotide triphosphate.

Plant or fungal sequences? An alternative optimized PCR protocol to avoid ITS (nrDNA) misamplification

open access: yesBrazilian Archives of Biology and Technology, 2010
The nuclear ribosomal DNA internal transcribed spacers (ITS1 and ITS2) from leaves of Drosera (Droseraceae) were amplified using "universal" primers.

Computational Investigations on Polymerase Actions in Gene Transcription and Replication Combining Physical Modeling and Atomistic Simulations [PDF]

open access: yesChin. Phys. B Vol. 25, No. 1 (2016) 018706, 2015
Polymerases are protein enzymes that move along nucleic acid chains and catalyze template-based polymerization reactions during gene transcription and replication. The polymerases also substantially improve transcription or replication fidelity through the non-equilibrium enzymatic cycles.

Recombinant GII.Pe-GII.4 Norovirus, Thailand, 2017–2018

open access: yesEmerging 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).

Chicken eEF1α is a Critical Factor for the Polymerase Complex Activity of Very Virulent Infectious Bursal Disease Virus

open access: yesViruses, 2020
Infectious bursal disease (IBD) is an immunosuppressive, highly contagious, and lethal disease of young chickens caused by IBD virus (IBDV). It results in huge economic loss to the poultry industry worldwide.

Structure and Function of Caliciviral RNA Polymerases

open access: yesViruses, 2017
Caliciviruses are a leading agent of human and animal gastroenteritis and respiratory tract infections, which are growing concerns in immunocompromised individuals. However, no vaccines or therapeutics are yet available.

Functional Insights into ANP32A-Dependent Influenza A Virus Polymerase Host Restriction

open access: yesCell 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

Stochastic resetting in backtrack recovery by RNA polymerases [PDF]

open access: yesPhys. Rev. E 93, 062411 (2016), 2016
Transcription is a key process in gene expression, in which RNA polymerases produce a complementary RNA copy from a DNA template. RNA polymerization is frequently interrupted by backtracking, a process in which polymerases perform a random walk along the DNA template.
