Book Description
Maintenance of the information embedded in the genomic DNA sequence is essential for life. DNA polymerases play pivotal roles in the complex physiological processes of DNA replication and repair. Besides the tasks in vivo, DNA polymerases are the workhorses in numerous biotechniques such as polymerase chain reaction (PCR), cDNA cloning, genome sequencing, nucleic acids–based diagnostics, as well as techniques to analyze ancient and otherwise damaged DNA. The authors have recently witnessed the discovery of a plethora of novel DNA polymerases with specialized properties whose physiological functions are only just beginning to be understood. This book summarizes the current knowledge of these fascinating enzymes in viruses, bacteria, archaea and eukaryotes. Moreover, some diseases are related to DNA polymerase defects, and chemotherapy through inhibition of DNA polymerases is used to fight HIV, Herpes, as well as Hepatitis B and C infections. This book will appeal to a broad audience including basic scientists, diagnostic laboratories, and clinicians who will gain an invaluable understanding of these fascinating enzymes.

Book Description
Maintenance of the information embedded in the genomic DNA sequence is essential for life. DNA polymerases play pivotal roles in the complex processes that maintain genetic integrity. Besides their tasks in vivo, DNA polymerases are the workhorses in numerous biotechnology applications such as the polymerase chain reaction (PCR), cDNA cloning, next generation sequencing, nucleic acids based diagnostics and in techniques to analyze ancient and otherwise damaged DNA (e.g. for forensic applications). Moreover, some diseases are related to DNA polymerase defects and chemotherapy through inhibition of DNA polymerases is used to fight HIV, Herpes and Hepatitis B and C infections. This book focuses on (i) biology of DNA polymerases, (ii) medical aspects of DNA polymerases and (iii) biotechnological applications of DNA polymerases. It is intended for a wide audience from basic scientists, to diagnostic laboratories, to companies and to clinicians, who seek a better understanding and the practical use of these fascinating enzymes.

Book Description
The work described in this dissertation focuses on several aspects of DNA replication in the model organism Saccharomyces cerevisiae, with particular attention paid to the function of the replicative DNA polymerase [delta] (Pol [delta]), and its functions in Okazaki fragment synthesis and maturation. The first major theme of this dissertation is investigating the role that metal binding motifs play in the structure and function of Pol [delta] and other budding yeast polymerases. First, I discuss the role that two metal binding motifs within the catalytic subunit of Pol [delta] play in creating the multi-subunit polymerase complex and in promoting crucial interactions with the replication sliding clamp, proliferating cell nuclear antigen (PCNA). Next, I describe work defining the importance of similar metal binding motifs in the translesion DNA polymerase [zeta] (Pol [zeta]). This yielded the observation that the two accessory subunits of Pol [delta], Pol31 and Pol32, are also constitutive members of a four-subunit Pol [zeta] complex. Finally, I describe the creation of a chimeric DNA polymerase comprising the bacteriophage RB69 DNA polymerase fused to the metal binding domain of the Pol [delta] catalytic subunit. We show that this chimeric polymerase can form a multimeric complex containing the Pol [delta] accessory subunits, interact with PCNA, and support DNA replication in vivo. This data provided insight into the structural requirements of the lagging strand replication machinery. The second major theme is Pol [delta]'s crucial role in synthesizing Okazaki fragments and participating in the removal of initiator RNA, called Okazaki fragment maturation. I first describe my work developing a system to study the activity of Pol [delta] in higher kinetic detail than previous studies, using rapid-quench techniques. This work yielded insights into how Pol [delta] performs DNA synthesis and strand displacement synthesis, as well as accomplishes nick translation, requiring collaboration between Pol [delta] and the flap-endonuclease FEN1. The next chapter describes the production and characterization of engineered PCNA heterotrimers. These proteins were produced to test the 'toolbelt' model, which is the hypothesis that PCNA binds multiple enzymes simultaneously to increase the efficiency of DNA metabolism processes involving multiple enzymes. Finally, there has been a growing interest among those studying lagging strand synthesis into how potential impediments to the Okazaki fragment maturation machinery are resolved; we show that although the transcription factor Rap1 can block strand displacement synthesis by Pol [delta] when it is bound to DNA, this block can be resolved through the action of the helicase Pif1. In sum, these studies provide insight into how Pol [delta]'s structure dictates its function, as well as addresses larger mechanistic questions concerning how lagging strand DNA replication is accomplished.

Book Description
DNA Repair and Replication contains an up-to-date review of general principles of DNA replication and an overview of the multiple pathways involved in DNA repair. Specific DNA repair pathways, including base-excision repair, light-dependent direct reversal of UV-damage, nucleotide-excision repair, transcription-coupled repair, double-strand break repair, and mismatch repair, are each discussed in separate chapters.Selected Contents: - Base Excision Repair - Eukaryotic DNA Mismatch Repair - Double Strand Break Repair - Functions of DNA Polymerases - Somatic Hypermutation: A Mutational Panacea

Book Description
This book provides a review of the multitude of nucleic acid polymerases, including DNA and RNA polymerases from Archea, Bacteria and Eukaryota, mitochondrial and viral polymerases, and other specialized polymerases such as telomerase, template-independent terminal nucleotidyl transferase and RNA self-replication ribozyme. Although many books cover several different types of polymerases, no book so far has attempted to catalog all nucleic acid polymerases. The goal of this book is to be the top reference work for postgraduate students, postdocs, and principle investigators who study polymerases of all varieties. In other words, this book is for polymerase fans by polymerase fans. Nucleic acid polymerases play a fundamental role in genome replication, maintenance, gene expression and regulation. Throughout evolution these enzymes have been pivotal in transforming life towards RNA self-replicating systems as well as into more stable DNA genomes. These enzymes are generally extremely efficient and accurate in RNA transcription and DNA replication and share common kinetic and structural features. How catalysis can be so amazingly fast without loss of specificity is a question that has intrigued researchers for over 60 years. Certain specialized polymerases that play a critical role in cellular metabolism are used for diverse biotechnological applications and are therefore an essential tool for research.

Book Description
Replicating and Repairing the Genome provides a concise overview of the fields of DNA replication and repair. The book is particularly appropriate for graduate students and advanced undergraduates, and scientists entering the field or working in related fields. The breadth of information regarding DNA replication and repair is vast and often difficult to absorb, with terminology that differs between experimental systems and with complex interconnections of these processes with other cellular pathways. This book provides simple conceptual descriptions of replication and repair pathways using mostly generic protein names, laying out the logic for how the pathways function and highlighting fascinating aspects of the underlying biochemical mechanisms and biology. The book incorporates extensive and informative diagrams and figures, as well as descriptions of a number of carefully chosen experiments that had major influences in the field.The process of DNA replication is explained progressively by starting with the system of a simple bacterial virus that uses only a few proteins, followed by the well-understood bacterial (E coli) system, and then culminating with the more complex eukaryotic systems. In the second half of the book, individual chapters cover key areas of DNA repair — postreplication repair of mismatches and incorporated ribonucleotides, direct damage reversal, excision repair, and DNA break repair, as well as the related areas of DNA damage tolerance (including translesion DNA polymerases) and DNA damage responses. The book closes with chapters that describe the huge impact of DNA replication and repair on aspects of human health and on modern biotechnology.
