Molecular Biophysics for the Life Sciences

This book covers research themes and strategies in molecular biophysics. It explains the goals of biophysical research as well as details investigative tools, the relevance of biological research to other fields, and future opportunities in the field.

This volume provides an overview of the development and scope of molecular biophysics and in-depth discussions of the major experimental methods that enable biological macromolecules to be studied at atomic resolution. It also reviews the physical chemical concepts that are needed to interpret the experimental results and to understand how the structure, dynamics, and physical properties of biological macromolecules enable them to perform their biological functions. Reviews of research on three disparate biomolecular machinesDNA helicases, ATP synthases, and myosin--illustrate how the combination of theory and experiment leads to new insights and new questions.

Provides an overview of major research themes and research strategies in contemporary molecular biophysics Introduces new investigators to major areas of biophysics Explains the goals of biophysical research, while offering the tools available for investigation, the relevance of biological research to other fields, and future opportunities in the field

This volume of the series Biophysics for the Life Sciences focuses on the conceptual framework and major research tools of contemporary molecular biophysics. It is designed to enable non-specialistsboth students and professionals in other fieldsto understand how these approaches can be used across the biosciences and in medicine, agriculture, biotechnology, pharmaceutical development and other fields. The scope of this volume is appropriate for advanced undergraduate and graduate courses in biophysics and biophysical chemistry.

The book begins with an overview of the development of molecular biophysics and a brief survey of structural, physical, and chemical principles. Subsequent chapters written by experts present, with examples, the major experimental methods: optical spectroscopy, X-ray and neutron diffraction and scattering, nuclear magnetic resonance, electron paramagnetic resonance, mass spectrometry, and single molecule methods. The relationship between the biophysical properties of biological macromolecules and their roles as molecular machines is emphasized throughout and illustrated with three examplesDNA helicases, rotary motor ATPases, and myosin. The concluding chapter discusses future prospects in X-ray and neutron scattering, mass spectrometry, and pharmaceutical development.
