Book Description
In recent years, a number of groundbreaking structural and mechanistic studies deepened our understanding of helicase mechanisms and established new approaches for their analyses. Many fundamental mechanistic questions ranging from the mechanism of force generation, mechanochemical coupling to distinct mechanisms by which the same enzyme translocates on DNA removing obstacles, unwinds DNA and/or remodels nucleoprotein complexes, however, remain to be answered. It is even less understood how the helicase motors are incorporated into a wide range of genome maintenance and repair machines. The field has reached a stage when the studies of molecular mechanisms and basic biology of helicases can and shall be integrated with the studies of development, cancer and longevity. The objective of this book is to provide the first systematic overview of structure, function and regulation of DNA helicases and related molecular motors. By integrating the knowledge obtained through the diverse technical approaches ranging from single-molecule biophysics to cellular and molecular biological studies the editors aim to provide a unified view on how helicases function in the cell, are regulated in response to different cellular stresses and are integrated into large macromolecular assemblies to form a complex and adaptive living system.

Book Description
This is an introductory text and laboratory manual to be used primarily in undergraduate courses. It is also useful for graduate students and research scientists who require an introduction to the theory and methods of nanopore sequencing. The book has clear explanations of the principles of this emerging technology, together with instructional material written by experts that describes how to use a MinION nanopore instrument for sequencing in research or the classroom.At Harvard University the book serves as a textbook and lab manual for a university laboratory course designed to intensify the intellectual experience of incoming undergraduates while exploring biology as a field of concentration. Nanopore sequencing is an ideal topic as a path to encourage students about the range of courses they will take in Biology by pre-emptively addressing the complaint about having to take a course in Physics or Maths while majoring in Biology. The book addresses this complaint by concretely demonstrating the range of topics — from electricity to biochemistry, protein structure, molecular engineering, and informatics — that a student will have to master in subsequent courses if he or she is to become a scientist who truly understands what his or her biology instrument is measuring when investigating biological phenomena.

Book Description
Helicases are ubiquitous enzymes found throughout evolution. Research in the helicase field has been going on for a long time now but in recent past with the completion of so many genomes, these enzymes have been discovered in a number of organisms. But the available literature is scattered. The huge number of identified DNA and RNA helicases, along with the structural and functional differences among them, make difficult for the interested scholar to grasp a comprehensive view of the field. Helicases from all Domains of Life is the first book to compile information about helicases from many different organisms in one place. Knowledge of the functions and features of helicases across the different kingdoms of life are a valuable source of novel ideas and information The book begins with a chapter on the evolutionary history of helicases followed by three "overview" chapters: one for bacteria/archaea (which are not mentioned), one for plants/algae and one for human helicases The overview chapters are followed by specific chapters on selected helicases of great importance from a biological/applicative point of view

Book Description
Helicases from All Domains of Life is the first book to compile information about helicases from many different organisms in a single volume. Research in the helicase field has been going on for a long time now, but the completion of so many genomes of these ubiquitous enzymes has made it difficult to keep up with new discoveries. As the huge number of identified DNA and RNA helicases, along with the structural and functional differences among them, make it difficult for the interested scholar to grasp a comprehensive view of the field, this book helps fill in the gaps. - Presents updates on the functions and features of helicases across the different kingdoms - Begins with a chapter on the evolutionary history of helicases - Contains specific chapters on selected helicases of great importance from a biological/applicative point-of-view

Book Description
The first edition of this book, published in 1999 and called DNA Repair Protocols: Eukaryotic Systems, brought together laboratory-based methods for studying DNA damage and repair in diverse eukaryotes: namely, two kinds of yeast, a nematode, a fruit fly, a toad, three different plants, and human and murine cells. This second edition of DNA Repair Protocols covers mammalian cells only and hence its new subtitle, Mammalian Systems. There are two reasons for this fresh emphasis, both of them pragmatic: to cater to the interests of what is now a largely mammalocentric DNA repair field, and to expedite editing and prod- tion of this volume. Although DNA Repair Protocols: Mammalian Systems is a smaller book than its predecessor, it actually contains a greater variety of methods. Fourteen of the book’s thirty-two chapters are entirely new and areas of redundancy present in the first edition have been eliminated here (for example, now just two chapters describe assays for nucleotide excision repair [NER], rather than seven). All eighteen returning chapters have been revised, many of them ext- sively. In order to maintain a coherent arrangement of topics, the four-part p- titioning seen in the first edition was dispensed with and chapters concerned with ionizing radiation damage and DNA strand breakage and repair were re- cated to near the front of the book. Finally, an abstract now heads each chapter.

Book Description
This volume of Methods in Enzymology aims to provide a reference for the diverse, powerful tools used to analyze RNA helicases. The contributions in this volume cover the broad scope of methods in the research on these enzymes. Several chapters describe quantitative biophysical and biochemical approaches to study molecular mechanisms and conformational changes of RNA helicases. Further chapters cover structural analysis, examination of co-factor effects on several representative examples, and the analysis of cellular functions of select enzymes. Two chapters outline approaches to the analysis of inhibitors that target RNA helicases. - This volume of Methods in Enzymology aims to provide a reference for the diverse, powerful tools used to analyze RNA helicases - The contributions in this volume cover the broad scope of methods in the research on these enzymes

Book Description
This volume examines a number of different molecular motors that utilize ATP. The molecular machines to be discussed include ATP synthase, myosin, kinesin, DNA helicases, DNA topoisomerases, chaperones and bacterial rotory motors. The discussion of these various molecular motors is rarely undertaken in one volume and will serve as a great resource for scientists studying structure and function of multiprotein complexes as well as those working on energy coupling mechanisms. The areas of research presented in this volume do not normally overlap, and yet they share common mechanisms.This volume examines a number of different molecular motors that utilize ATP.

Book Description
There has been a sea change in how we view genetic recombination. When germ cells are produced in higher organisms, genetic recombination assures the proper segregation of like chromosomes. In the course of that process, called meiosis, recombination not only assures segregation of one chromosome of each type to progeny germ cells, but also further shuffles the genetic deck, contributing to the unique inheritance of individuals. In a nutshell, that is the classical view of recombination. We have also known for many years that in bacteria recombination plays a role in horizontal gene transfer and in replication itself, the latter by establishing some of the replication forks that are the structural scaffolds for copying DNA. In recent years, however, we have become increasingly aware that replication, which normally starts without any help from recombination, is a vulnerable process that frequently leads to broken DNA. The enzymes of recombination play a vital role in the repair of those breaks. The recombination enzymes can function via several different pathways that mediate the repair of breaks, as well as restoration of replication forks that are stalled by other kinds of damage to DNA. Thus, to the classical view of recombination as an engine of inheritance we must add the view of recombination as a vital housekeeping function that repairs breaks suffered in the course of replication. We have also known for many years that genomic instability--including mutations, chromosomal rearrangements, and aneuploidy--is a hallmark of cancer cells. Although genomic instability has many contributing causes, including faulty replication, there are many indications that recombination, faulty or not, contributes to genome instability and cancer as well. The (Nas colloquium) Links Between Recombination and Replication: Vital Roles of Recombination was convened to broaden awareness of this evolving area of research. Papers generated by this colloquium are published here. To encourage the desired interactions of specialists, we invited some contributions that deal only with recombination or replication in addition to contributions on the central thesis of functional links between recombination and replication. To aid the nonspecialist and specialist alike, we open the set of papers with a historical overview by Michael Cox and we close the set with a commentary on the meeting and the field by Andrei Kuzminov.
