The DNA polymerases of Drosophila melanogaster

open access: yesFly, 2020
DNA synthesis during replication or repair is a fundamental cellular process that is catalyzed by a set of evolutionary conserved polymerases.

DNA Helicase–Polymerase Coupling in Bacteriophage DNA Replication

open access: yesViruses, 2021
Bacteriophages have long been model systems to study the molecular mechanisms of DNA replication. During DNA replication, a DNA helicase and a DNA polymerase cooperatively unwind the parental DNA.

The Loop of the TPR1 Subdomain of Phi29 DNA Polymerase Plays a Pivotal Role in Primer-Terminus Stabilization at the Polymerization Active Site

open access: yesBiomolecules, 2019
Bacteriophage Phi29 DNA polymerase belongs to the protein-primed subgroup of family B DNA polymerases that use a terminal protein (TP) as a primer to initiate genome replication. The resolution of the crystallographic structure showed that it consists of

DNA Polymerase-Catalyzed DNA Network Growth [PDF]

open access: yesJournal of the American Chemical Society, 2008
The distinct base pairing property of DNA is an advantageous phenomenon that has been exploited in the usage of DNA as scaffold for directed self-organization to form nanometer-sized objects in a desirable fashion. Herein we report the construction of three-dimensional DNA-based networks that can be generated and amplified by the DNA polymerase chain ...

Nsp1 stalls DNA polymerase α at DNA hairpins. [PDF]

open access: yesSci Rep
The human primosome, a four-subunit complex of DNA primase and DNA polymerase alpha (Polα), plays a critical role in DNA replication by initiating RNA and DNA synthesis on both chromosome strands. A recent study has shown that a major virulence factor in

PrimPol is required for replicative tolerance of G quadruplexes in vertebrate cells [PDF]

open access: yes, 2016
G quadruplexes (G4s) can present potent blocks to DNA replication. Accurate and timely replication of G4s in vertebrates requires multiple specialized DNA helicases and polymerases to prevent genetic and epigenetic instability.

Polymerase Mu Is a DNA-Directed DNA/RNA Polymerase [PDF]

open access: yesMolecular and Cellular Biology, 2003
DNA polymerases are defined as such because they use deoxynucleotides instead of ribonucleotides with high specificity. We show here that polymerase mu (pol μ), implicated in the nonhomologous end-joining pathway for repair of DNA double-strand breaks, incorporates both ribonucleotides and deoxynucleotides in a template-directed manner.

Analysis of nucleotide insertion opposite urea and translesion synthesis across urea by DNA polymerases

open access: yesGenes and Environment, 2022
Urea (Ua) is produced in DNA as the result of oxidative damage to thymine and guanine. It was previously reported that Klenow fragment (Kf) exo− incorporated dATP opposite Ua, and that DNA polymerase β was blocked by Ua.

Translesion synthesis in mammalian cells [PDF]

open access: yes, 2006
DNA damage blocks the progression of the replication fork. In order to circumvent the damaged bases, cells employ specialized low stringency DNA polymerases, which are able to carry out translesion synthesis (TLS) past different types of damage. The five

Mismatch repair in recombination of bacteriophage T4

open access: yesBiomolecular Concepts, 2012
The review focuses on the mechanism of mismatch repair in bacteriophage T4. It was first observed in T4 as an extra recombination mechanism, which contributed to the general recombination only when particular rII mutations were used as genetic markers ...
