Available in PDF, EPUB and Kindle. Book excerpt: To thrive, every living cell must continuously gauge and respond to changes in its environment. These changes are ultimately implemented by modulating gene expression, a process that relies on transcription by Nature’s most multivalent molecular machine, the RNA polymerase. This book covers progress made over the past decade understanding how this machine functions to compute the cellular state, from the atomistic structural level responsible for chemistry to the integrative level at which RNA polymerase interacts with the other key molecular machineries of the cell.
Download or read book Principles of Brownian and Molecular Motors written by José Antonio Fornés and published by Springer Nature. This book was released on 2021-02-04 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular motors convert chemical energy (typically from ATP hydrolysis) to directed motion and mechanical work. Biomolecular motors are proteins able of converting chemical energy into mechanical motion and force. Because of their dimension, the many small parts that make up molecular motors must operate at energies only a few times greater than those of the thermal baths. The description of molecular motors must be stochastic in nature. Their actions are often described in terms of Brownian Ratchets mechanisms. In order to describe the principles used in their movement, we need to use the tools that theoretical physics give us. In this book we centralize on the some physical mechanisms of molecular motors.

Download or read book Mechanics of Motor Proteins and the Cytoskeleton written by Jonathon Howard and published by Sinauer. This book was released on 2005-12-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanics of Motor Proteins and the Cytoskeleton provides a physical foundation for molecular mechanics. Part I explains how small particles like proteins respond to mechanical, thermal, and chemical forces, Part II focuses on cytoskeletal filaments, and Part III focuses on motor proteins. The treatments are unified in the respect that they are organized around principles rather than proteins: chapters are centred on topics such as structure, chemistry, and mechanics, and different filaments or motors are discussed together.
Download or read book Molecular Motors in Bionanotechnology written by Keith Firman and published by CRC Press. This book was released on 2013-03-18 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological molecular motors provide most cells with the dynamic systems required for their day-to-day existence. Examples occur in even the simplest organism (e.g. a bacteria virus), and the range of tasks that they carry out is vast. Over the last few years, there has been a large increase in the study of these motors, and it is becoming apparent that many motors will find uses in either bionanotechnology or synthetic biology. Molecular Motors in Bionanotechnology describes a wide range of molecular motors, ranging from chemical motors to biological motors, in a manner that updates, or reviews, both classification of the type of motor and the grouping into families. Many techniques have evolved to study and characterise molecular motors at the single-molecule level (e.g. use of molecular tweezer devices for single-molecule studies). The text introduces the reader to the concepts and benefits of these techniques. In addition, it looks at the structural information and how this helps understand function and, finally, how some of these motors are being used or may be used in the future as part of a synthetic biology approach to building devices and sensors.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book RNA Polymerases as Molecular Motors written by Henri C. Buc and published by Royal Society of Chemistry. This book was released on 2009-04-16 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, written by expert scientists in the field, analyses how these diverse fields of research interact on a specific example - RNA polymerase. The book concentrates on RNA polymerases because they play a central role among all the other machines operating in the cell and are the target of a wide range of regulatory mechanisms. They have also been the subject of spectacular advances in their structural understanding in recent years, as testified by the attribution of the Nobel prize in chemistry in 2006 to Roger Kornberg. The book focuses on two aspects of the transcription cycle that have been more intensively studied thanks to this increased scientific cooperation - the recognition of the promoter by the enzyme, and the achievement of consecutive translocation steps during elongation of the RNA product. Each of these two topics is introduced by an overview, and is then presented by worldwide experts in the field, taking the viewpoint of their specialty. The overview chapters focus on the mechanism-structure interface and the structure-machine interface while the individual chapters within each section concentrate more specifically on particular processes-kinetic analysis, single-molecule spectroscopy, and termination of transcription, amongst others. Specific attention has been paid to the newcomers in the field, with careful descriptions of new emerging techniques and the constitution of an atlas of three-dimensional pictures of the enzymes involved.

Download or read book Coarse grained Structural Modeling of Molecular Motors written by David William Parker and published by Stanford University. This book was released on 2011 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular motors perform central functions in fundamental biological processes, including cell division, DNA replication, muscle contraction, and intracellular transport. Experimental and computational approaches are needed to uncover the mechanisms by which molecular motors convert chemical energy into mechanical work. A software system called Protein Mechanica has been developed to generate structurally realistic models of molecular motor conformations compatible with experimental data from different sources. It facilitates the construction of models of protein geometry from atomic resolution structures, lower-resolution electron microscopy data and parametric solids. Coarse-grained models of molecular structures are constructed by combining groups of atoms into a system of rigid bodies connected by joints. Contacts between rigid bodies enforce excluded volume constraints, and spring potentials model system elasticity. This simplified representation allows the conformations of complex molecular motors to be simulated interactively, providing a tool for hypothesis building and quantitative comparisons between models and experiments. Protein Mechanica was used to build an atomic-resolution model of a mouse brain myosin V, a dimeric cellular transport motor, in pre- and post powerstroke conformations from partial X-ray crystal structures. A mechanical analysis of the head-neck region model was performed using normal mode analyses and molecular dynamics simulations to guide the construction of a coarse-grained models. The coarse-grained model of myosin V enabled examination of its conformations bound to its actin track. Elastic strain energies calculated from simulations are compatible with observations of single myosin V motors traversing suspended actin filaments that infer that the motor uses a combination of 11 subunit and 13 subunit stride sizes. These calculations extend previous simple mechanical models for step size selection and processivity, and provide atomically detailed models for comparison with future experiments. The Protein Mechanica software described in this dissertation provides a new tool for structural modeling of many different molecular machines, basic understanding and engineering design.
