Fidelity of DNA polymerases in the detection of intraindividual variation of mitochondrial DNA.

ABSTRACT: Here we investigated the consequences of PCR amplification errors in the identification of intraindividual mtDNA variation. The bumblebee Bombus morio was chosen as model for the COI gene amplification tests with two DNA polymerases (Taq and Q5) presenting different error rates. The amplifications using Taq resulted in a significant increase of singleton haplotypes per individual in comparison to Q5. The sequence characteristics indicated that Taq resulted haplotypes are mostly due to amplification errors. Studies focusing on intraindividual variability should address special attention to the DNA polymerase fidelity to avoid overestimation of heteroplasmic haplotypes.

Lesion processing: high-fidelity versus lesion-bypass DNA polymerases.

Project description:When a high-fidelity DNA polymerase encounters certain DNA-damage sites, its progress can be stalled and one or more lesion-bypass polymerases are recruited to transit the lesion. Here, we consider two representative types of lesions: (i) 7,8-dihydro-8-oxoguanine (8-oxoG), a small, highly prevalent lesion caused by oxidative damage; and (ii) bulky lesions derived from the environmental pre-carcinogen benzo[a]pyrene, in the high-fidelity DNA polymerase Bacillus fragment (BF) from Bacillus stearothermophilus and in the lesion-bypass DNA polymerase IV (Dpo4) from Sulfolobus solfataricus. The tight fit of the BF polymerase around the nascent base pair contrasts with the more spacious, solvent-exposed active site of Dpo4, and these differences in architecture result in distinctions in their respective functions: one-step versus stepwise polymerase translocation, mutagenic versus accurate bypass of 8-oxoG, and polymerase stalling versus mutagenic bypass at bulky benzo[a]pyrene-derived lesions.

The kinetic and chemical mechanism of high-fidelity DNA polymerases.

Project description:This review summarizes our current understanding of the structural, kinetic and thermodynamic basis for the extraordinary accuracy of high-fidelity DNA polymerases. High-fidelity DNA polymerases, such as the enzyme responsible for the replication of bacteriophage T7 DNA, discriminate against similar substrates with an accuracy that approaches one error in a million base pairs while copying DNA at a rate of approximately 300 base pairs per second. When the polymerase does make an error, it stalls, giving time for the slower proofreading exonuclease to remove the mismatch so that the overall error frequency approaches one in a billion. Structural analysis reveals a large change in conformation after nucleotide binding from an open to a closed state. Kinetic analysis has shown that the substrate-induced structural change plays a key role in the discrimination between correct and incorrect base pairs by governing whether a nucleotide will be retained and incorporated or rapidly released.

Both high-fidelity replicative and low-fidelity Y-family polymerases are involved in DNA rereplication.

Project description:DNA rereplication is a major form of aberrant replication that causes genomic instabilities, such as gene amplification. However, little is known about which DNA polymerases are involved in the process. Here, we report that low-fidelity Y-family polymerases (Y-Pols), Pol η, Pol ι, Pol κ, and REV1, significantly contribute to DNA synthesis during rereplication, while the replicative polymerases, Pol δ and Pol ε, play an important role in rereplication, as expected. When rereplication was induced by depletion of geminin, these polymerases were recruited to rereplication sites in human cell lines. This finding was supported by RNA interference (RNAi)-mediated knockdown of the polymerases, which suppressed rereplication induced by geminin depletion. Interestingly, epistatic analysis indicated that Y-Pols collaborate in a common pathway, independently of replicative polymerases. We also provide evidence for a catalytic role for Pol η and the involvement of Pol η and Pol κ in cyclin E-induced rereplication. Collectively, our findings indicate that, unlike normal S-phase replication, rereplication induced by geminin depletion and oncogene activation requires significant contributions of both Y-Pols and replicative polymerases. These findings offer important mechanistic insights into cancer genomic instability.

Efficiency and fidelity of human DNA polymerases ? and ? during gap-filling DNA synthesis.

Project description:The base excision repair (BER) pathway coordinates the replacement of 1-10 nucleotides at sites of single-base lesions. This process generates DNA substrates with various gap sizes which can alter the catalytic efficiency and fidelity of a DNA polymerase during gap-filling DNA synthesis. Here, we quantitatively determined the substrate specificity and base substitution fidelity of human DNA polymerase ? (Pol ?), an enzyme proposed to support the known BER DNA polymerase ? (Pol ?), as it filled 1-10-nucleotide gaps at 1-nucleotide intervals. Pol ? incorporated a correct nucleotide with relatively high efficiency until the gap size exceeded 9 nucleotides. Unlike Pol ?, Pol ? did not have an absolute threshold on gap size as the catalytic efficiency for a correct dNTP gradually decreased as the gap size increased from 2 to 10 nucleotides and then recovered for non-gapped DNA. Surprisingly, an increase in gap size resulted in lower polymerase fidelity for Pol ?, and this downregulation of fidelity was controlled by its non-enzymatic N-terminal domains. Overall, Pol ? was up to 160-fold more error-prone than Pol ?, thereby suggesting Pol ? would be more mutagenic during long gap-filling DNA synthesis. In addition, dCTP was the preferred misincorporation for Pol ? and its N-terminal domain truncation mutants. This nucleotide preference was shown to be dependent upon the identity of the adjacent 5'-template base. Our results suggested that both Pol ? and Pol ? would catalyze nucleotide incorporation with the highest combination of efficiency and accuracy when the DNA substrate contains a single-nucleotide gap. Thus, Pol ?, like Pol ?, is better suited to catalyze gap-filling DNA synthesis during short-patch BER in vivo, although, Pol ? may play a role in long-patch BER.

Different Divalent Cations Alter the Kinetics and Fidelity of DNA Polymerases.

Project description:Divalent metal ions are essential components of DNA polymerases both for catalysis of the nucleotidyl transfer reaction and for base excision. They occupy two sites, A and B, for DNA synthesis. Recently, a third metal ion was shown to be essential for phosphoryl transfer reaction. The metal ion in the A site is coordinated by the carboxylate of two highly conserved acidic residues, water molecules, and the 3'-hydroxyl group of the primer so that the A metal is in an octahedral complex. Its catalytic function is to lower the pKa of the hydroxyl group, making it a highly effective nucleophile that can attack the α phosphorous atom of the incoming dNTP. The metal ion in the B site is coordinated by the same two carboxylates that are affixed to the A metal ion as well as the non-bridging oxygen atoms of the incoming dNTP. The carboxyl oxygen of an adjacent peptide bond serves as the sixth ligand that completes the octahedral coordination geometry of the B metal ion. Similarly, two metal ions are required for proofreading; one helps to lower the pKa of the attacking water molecule, and the other helps to stabilize the transition state for nucleotide excision. The role of different divalent cations are discussed in relation to these two activities as well as their influence on base selectivity and misincorporation by DNA polymerases. Some, but not all, of the effects of these different metal ions can be rationalized based on their intrinsic properties, which are tabulated in this review.

WRN exonuclease imparts high fidelity on translesion synthesis by Y family DNA polymerases.

Project description:Purified translesion synthesis (TLS) DNA polymerases (Pols) replicate through DNA lesions with a low fidelity; however, TLS operates in a predominantly error-free manner in normal human cells. To explain this incongruity, here we determine whether Y family Pols, which play an eminent role in replication through a diversity of DNA lesions, are incorporated into a multiprotein ensemble and whether the intrinsically high error rate of the TLS Pol is ameliorated by the components in the ensemble. To this end, we provide evidence for an indispensable role of Werner syndrome protein (WRN) and WRN-interacting protein 1 (WRNIP1) in Rev1-dependent TLS by Y family Polη, Polι, or Polκ and show that WRN, WRNIP1, and Rev1 assemble together with Y family Pols in response to DNA damage. Importantly, we identify a crucial role of WRN's 3' → 5' exonuclease activity in imparting high fidelity on TLS by Y family Pols in human cells, as the Y family Pols that accomplish TLS in an error-free manner manifest high mutagenicity in the absence of WRN's exonuclease function. Thus, by enforcing high fidelity on TLS Pols, TLS mechanisms have been adapted to safeguard against genome instability and tumorigenesis.

Intraindividual variation and short-term temporal trend in DNA methylation of human blood.

Project description:BackgroundBetween- and within-person variation in DNA methylation levels are important parameters to be considered in epigenome-wide association studies. Temporal change is one source of within-person variation in DNA methylation that has been linked to aging and disease.MethodsWe analyzed CpG-site-specific intraindividual variation and short-term temporal trend in leukocyte DNA methylation among 24 healthy Chinese women, with blood samples drawn at study entry and after 9 months. Illumina HumanMethylation450 BeadChip was used to measure methylation. Intraclass correlation coefficients (ICC) and trend estimates were summarized by genomic location and probe type.ResultsThe median ICC was 0.36 across nonsex chromosomes and 0.80 on the X chromosome. There was little difference in ICC profiles by genomic region and probe type. Among CpG loci with high variability between participants, more than 99% had ICC > 0.8. Statistically significant trend was observed in 10.9% CpG loci before adjustment for cell-type composition and in 3.4% loci after adjustment.ConclusionsFor CpG loci differentially methylated across subjects, methylation levels can be reliably assessed with one blood sample. More samples per subject are needed for low-variability and unmethylated loci. Temporal changes are largely driven by changes in cell-type composition of blood samples, but temporal trend unrelated to cell types is detected in a small percentage of CpG sites.ImpactThis study shows that one measurement can reliably assess methylation of differentially methylated CpG loci.

A binding free energy decomposition approach for accurate calculations of the fidelity of DNA polymerases.

Project description:DNA polymerase beta (pol beta) is a small eukaryotic enzyme with the ability to repair short single-stranded DNA gaps that has found use as a model system for larger replicative DNA polymerases. For all DNA polymerases, the factors determining their catalytic power and fidelity are the interactions between the bases of the base pair, amino acids near the active site, and the two magnesium ions. In this report, we study effects of all three aspects on human pol beta transition state (TS) binding free energies by reproducing a consistent set of experimentally determined data for different structures. Our calculations comprise the combination of four different base pairs (incoming pyrimidine nucleotides incorporated opposite both matched and mismatched purines) with four different pol beta structures (wild type and three mutants). We generate three fragments of the incoming deoxynucleoside 5'-triphosphate-TS and run separate calculations for the neutral base part and the highly charged triphosphate part, using different dielectric constants in order to account for the specific dielectric response. This new approach improves our ability to predict the effect of matched and mismatched base pairing and of mutations in DNA polymerases on fidelity and may be a useful tool in studying the potential of DNA polymerase mutations in the development of cancer. It also supports our point of view with regards to the origin of the structural control of fidelity, allowing for a quantified description of the fidelity of DNA polymerases.

Oxidative damage diminishes mitochondrial DNA polymerase replication fidelity.

Project description:Mitochondrial DNA (mtDNA) resides in a high ROS environment and suffers more mutations than its nuclear counterpart. Increasing evidence suggests that mtDNA mutations are not the results of direct oxidative damage, rather are caused, at least in part, by DNA replication errors. To understand how the mtDNA replicase, Pol γ, can give rise to elevated mutations, we studied the effect of oxidation of Pol γ on replication errors. Pol γ is a high fidelity polymerase with polymerase (pol) and proofreading exonuclease (exo) activities. We show that Pol γ exo domain is far more sensitive to oxidation than pol; under oxidative conditions, exonuclease activity therefore declines more rapidly than polymerase. The oxidized Pol γ becomes editing-deficient, displaying a 20-fold elevated mutations than the unoxidized enzyme. Mass spectrometry analysis reveals that Pol γ exo domain is a hotspot for oxidation. The oxidized exo residues increase the net negative charge around the active site that should reduce the affinity to mismatched primer/template DNA. Our results suggest that the oxidative stress induced high mutation frequency on mtDNA can be indirectly caused by oxidation of the mitochondrial replicase.

Computer simulations of protein functions: searching for the molecular origin of the replication fidelity of DNA polymerases.

Project description:The use of computers to simulate the functions of complex biological macromolecules is essential to achieve a microscopic description of biological processes and to model and interpret experimental data. Here we apply theoretical computational approaches to investigate the fidelity of T7 DNA polymerase, divided into discrete steps that include contributions from substrate binding, pK(a) shifts, and rate constants for the PO bond-breaking and bond-making processes. We begin by defining the discrimination between right and wrong nucleotides in terms of the free energy landscape for the dNMP incorporation reaction. We then use the linear response approximation and the empirical valence bond methods to obtain converging results for the contribution of the binding and chemical steps to the overall fidelity. These approaches are successful in reproducing general trends in the observed polymerase incorporation fidelity. The calculations demonstrate the potential for further integration of theoretical and experimental studies to analyze high- and low-fidelity DNA polymerases.
