Accessibility of DNA in Chromatin to DNA Polymerase and RNA Polymerase [PDF]

open access: yesProceedings of the National Academy of Sciences, 1973
The accessibility of DNA in chromatin to both exogenous DNA polymerase and RNA polymerase is slight when compared to isolated DNA. DNA in extracted chromatin is somewhat more accessible to these enzymes than is DNA in the chromatin of isolated nuclei; and the DNA template of chromatin is more accessible to DNA polymerase than to RNA polymerase.

Cloning of DNA Polymerase I Geobacillus thermoleovorans SGAir0734 from a Batu Kuwung Hot Spring in Escherichia coli

open access: yesInternational Journal of Technology, 2020
Access to biological engineering has become a critical point of modern science development through polymerase chain reaction (PCR). One of the main components in this process is DNA polymerase, which copies the main template DNA.

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.

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.

Polymerization Domain Translated from 0.9 kb Gene Fragment of DNA Polymerase I from a Thermo-Halophilic PLS A Strain

open access: yesJurnal Kimia Sains dan Aplikasi, 2020
The search for novel DNA Polymerases I, with higher fidelity and better polymerization rate, is essential to improve the Polymerase Chain Reaction method.

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.

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 ...

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

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.

DNA polymerases and cancer [PDF]

open access: yesNature Reviews Cancer, 2011
There are 15 different DNA polymerases encoded in mammalian genomes, which are specialized for replication, repair or the tolerance of DNA damage. New evidence is emerging for lesion-specific and tissue-specific functions of DNA polymerases. Many point mutations that occur in cancer cells arise from the error-generating activities of DNA polymerases ...
