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.

olymerases are the nucleotidyl transferases that are responsible for synthesizing DNA and RNA. They are crucial for essential cellular processes including cellular and viral genome replication, DNA repair and damage tolerance, and transcription. Consistent with their vital roles, polymerases are found in all domains of life. The overall chemistry employed by these enzymes is conserved but there are variations among the different groups of polymerases that confer different substrate specificities and nucleotide incorporation fidelities that allow them to be involved in a wide array of cellular activities. Since polymerases were first isolated more than six decades ago, we have made great progress in understanding how different polymerases have adapted to their specific roles. In this Research Topic we will focus on the enzymatic mechanisms of these enzymes and the relationships between polymerase structure and mechanism, to highlight common themes and unique adaptations.

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.

The First volume gives an overview of the enzymes involved in DNA synthesis and modification; the second volume deals with the RNA-enzymes. Although the major emphasis of the book is on eukaryotic enzymes, a separate chapter dealing with prokaryotic DNA repair enzymes has been included to discuss the major advances in this field in recent years. There are two separate chapters on RNA polymerases to provide a comprehensive coverage of the enzymes from lower eukaryotes, plants and higher eukaryotes.

DNA polymerases are core tools for molecular biology including PCR, whole genome amplification, DNA sequencing and genotyping. Research has focused on discovery of novel DNA polymerases, characterization of DNA polymerase biochemistry and development of new replication assays. These studies have accelerated DNA polymerase engineering for biotechnology. For example, DNA polymerases have been engineered for increased speed and fidelity in PCR while lowering amplification sequence bias. Inhibitor resistant DNA polymerase variants enable PCR directly from tissue (i.e. blood). Design of DNA polymerases that efficiently incorporate modified nucleotide have been critical for development of next generation DNA sequencing, synthetic biology and other labeling and detection technologies. The Frontiers in Microbiology Research Topic on DNA polymerases in Biotechnology aims to capture current research on DNA polymerases and their use in emerging technologies.
