Structure of the Helicase Domain of DNA Polymerase Theta Reveals a Possible Role in the Microhomology-Mediated End-Joining Pathway [PDF]

open access: yes, 2015
DNA polymerase theta (Polθ) has been identified as a crucial alternative non-homologous end-joining factor in mammalian cells. Polθ is upregulated in a range of cancer cell types defective in homologous recombination, and knockdown has been shown to ...

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

Eukaryotic DNA Polymerases

open access: yesAnnual Review of Biochemistry, 2002
▪ Abstract  Any living cell is faced with the fundamental task of keeping the genome intact in order to develop in an organized manner, to function in a complex environment, to divide at the right time, and to die when it is appropriate. To achieve this goal, an efficient machinery is required to maintain the genetic information encoded in DNA during ...

Translesion DNA Polymerases [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2013
Living cells are continually exposed to DNA-damaging agents that threaten their genomic integrity. Although DNA repair processes rapidly target the damaged DNA for repair, some lesions nevertheless persist and block genome duplication by the cell's replicase.

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.

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 ...

Promutagenicity of 8-Chloroguanine, A Major Inflammation-Induced Halogenated DNA Lesion

open access: yesMolecules, 2019
Chronic inflammation is closely associated with cancer development. One possible mechanism for inflammation-induced carcinogenesis is DNA damage caused by reactive halogen species, such as hypochlorous acid, which is released by myeloperoxidase to kill ...

A novel role of DNA polymerase λ in translesion synthesis in conjunction with DNA polymerase ζ

open access: yesLife Science Alliance, 2021
As an integral scaffolding component of DNA polymerase (Pol) zeta, Pol lambda adapts Pol zeta–dependent translesion synthesis to operate in a predominantly error-free manner in human cells.

Cyclocytidine hydrochloride inhibits the synthesis of relaxed circular DNA of hepatitis B virus [PDF]

open access: yesPeerJ, 2022
Background Cyclocytidine hydrochloride (HCl) has been reported to inhibit DNA synthesis by affecting DNA polymerase. Here, we tested the antiviral effect of cyclocytidine on hepatitis B virus (HBV) DNA synthesis, which is reliant on DNA polymerase ...

DNA Polymerase e - More Than a Polymerase

open access: yesThe Scientific World Journal, 2003
This paper presents a comprehensive review of the structure and function of DNA polymerase e. Together with DNA polymerases a and d, this enzyme replicates the nuclear DNA in the eukaryotic cell.
