Trypanosoma cruzi DNA Polymerase β Is Phosphorylated In Vivo and In Vitro by Protein Kinase C (PKC) and Casein Kinase 2 (CK2)

open access: yesCells, 2022
DNA polymerase β plays a fundamental role in the life cycle of Trypanosoma cruzi since it participates in the kinetoplast DNA repair and replication. This enzyme can be found in two forms in cell extracts of T. cruzi epimastigotes form.

Conformational Dynamics of DNA Polymerases Revealed at the Single-Molecule Level

open access: yesFrontiers in Molecular Biosciences, 2022
DNA polymerases are intrinsically dynamic macromolecular machines. The purpose of this review is to describe the single-molecule Förster resonance energy transfer (smFRET) methods that are used to probe the conformational dynamics of DNA polymerases ...

DNA Polymerase B1 Binding Protein 1 Is Important for DNA Repair by Holoenzyme PolB1 in the Extremely Thermophilic Crenarchaeon Sulfolobus acidocaldarius

open access: yesMicroorganisms, 2021
DNA polymerase B1 (PolB1) is a member of the B-family DNA polymerase family and is a replicative DNA polymerase in Crenarchaea. PolB1 is responsible for the DNA replication of both the leading and lagging strands in the thermophilic crenarchaeon ...

Fidelity of DNA polymerase I and the DNA polymerase I-DNA primase complex from Saccharomyces cerevisiae. [PDF]

open access: yesMolecular and Cellular Biology, 1989
We have determined the fidelity of DNA synthesis by DNA polymerase I (yPol I) from Saccharomyces cerevisiae. To determine whether subunits other than the polymerase catalytic subunit influence fidelity, we measured the accuracy of yPol I purified by conventional procedures, which yields DNA polymerase with a partially proteolyzed catalytic subunit and ...

Aptamer-based regulation of DNA polymerase activity for the detection of protein-small molecule interactions

open access: yesBiosensors and Bioelectronics: X, 2023
Herein, we developed a novel method for identifying protein-small molecule interactions (PSMIs) based on the switching of DNA polymerase activity. This strategy employs the small molecule-linked DNA probe (SMP) that could bind to and disrupt the DNA ...

Conditions for Using DNA Polymerase I as an RNA-Dependent DNA Polymerase [PDF]

open access: yesProceedings of the National Academy of Sciences, 1974
Conditions are described for using Escherichia coli DNA polymerase I for synthesizing complementary DNA copies of natural RNA molecules, which are suitable for use in hybridization experiments. The molar ratio of enzyme to template is critical; below a certain level, synthesis is not observed.

Opposed Steric Constraints in Human DNA Polymerase β and E. coli DNA Polymerase I [PDF]

open access: yesJournal of the American Chemical Society, 2008
DNA polymerase selectivity is crucial for the survival of any living species, yet varies significantly among different DNA polymerases. Errors within DNA polymerase-catalyzed DNA synthesis result from the insertion of noncanonical nucleotides and extension of misaligned DNA substrates.

The DNA polymerases of Drosophila melanogaster [PDF]

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. Despite a large body of research, the DNA polymerases of Drosophila melanogaster have not yet been systematically reviewed, leading to inconsistencies in their nomenclature, shortcomings in their functional ...

Bst polymerase — a humble relative of Taq polymerase

open access: yesComputational and Structural Biotechnology Journal, 2023
DNA polymerases are a superfamily of enzymes synthesizing DNA using DNA as a template. They are essential for nucleic acid metabolism and for DNA replication and repair.

Single-molecule view of coordination in a multi-functional DNA polymerase

open access: yeseLife, 2021
Replication and repair of genomic DNA requires the actions of multiple enzymatic functions that must be coordinated in order to ensure efficient and accurate product formation.
