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.

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.

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

RNA helicases and RNA helicase-like proteins are the largest group of enzymes in eukaryotic RNA metabolism and although they are subject to intense ongoing research there is much confusion about function and classification of these enzymes. Although these enzymes are essential for virtually all processes involving RNA, there is no overview detailing structure, function and/or biological roles of these pivotal proteins. This book provides the first comprehensive and systematic overview of biology, mechanism, and structure of RNA helicases and RNA helicase-like enzymes. Research into RNA helicases takes place in many different fields from cell and developmental biology to mechanistic enzymology, and structural biology and this book integrates the knowledge of these diverse fields into one valuable resource. It also provides an informative overview on the entire group of enzymes. Individual chapters on each subfamily of RNA helicases and RNA helicase-like proteins are written by experts in the respective fields. All chapters are systematically integrated and the reader is guided by a didactic introductory chapter. The main strengths of the book are the combination of systematics and details that will allow the reader to gain insight into results from diverse fields while maintaining a view of the entire field. It will be a key reference for academics, advanced students, researchers and professionals working in or joining this field.

This book focuses on the application of fluorescence to study motor proteins (myosins, kinesins, DNA helicases and RNA polymerases). It is intended for a large community of biochemists, biophysicists and cell biologists who study a diverse collection of motor proteins. It can be used by researchers to gain an insight into their first experiments, or by experienced researchers who are looking to expand their research to new areas. Each chapter provides valuable advice for executing the experiments, along with detailed background knowledge in order to develop own experiments.

Restriction enzymes are highly specific nucleases which occur ubiquitously among prokaryotic organisms, where they serve to protect bacterial cells against foreign DNA. Many different types of restriction enzymes are known, among them multi-subunit enzymes which depend on ATP or GTP hydrolysis for target site location. The best known representatives, the orthodox type II restriction endonucleases, are homodimers which recognize palindromic sequences, 4 to 8 base pairs in length, and cleave the DNA within or immediately adjacent to the recognition site. In addition to their important biological role (up to 10 % of the genomes of prokaryotic organisms code for restriction/modification systems!), they are among the most important enzymes used for the analysis and recombination of DNA. In addition, they are model systems for the study of protein-nucleic acids interactions and, because of their ubiquitous occurence, also for the understanding of the mechanisms of evolution.
