Opis

Computational modeling can provide a wealth of insight into how energy flow in proteins mediates protein function. Computational methods can also address fundamental questions related to molecular signaling and energy flow in proteins. Proteins: Energy, Heat and Signal Flow presents state-of-the-art computational strategies for studying energy redistribution, signaling, and heat transport in proteins and other molecular machines. The first of four sections of the book address the transport of energy in molecular motors, which function through a combination of chemically driven large-scale conformational changes and charge transport. Focusing on vibrational energy flow in proteins and nanostructures, the next two sections discuss approaches based on molecular dynamics simulations and harmonic analysis. By exploring the flow of free energy in proteins, the last section examines the conformational changes involved in allosteric transitions and the role of coupled protein solvent dynamics in conformational changes. It also presents computational approaches developed to locate pathways between protein structures. The integrated presentation of this comprehensive, up-to-date volume emphasizes the interrelations between disparate computational approaches that have contributed to our understanding of energy flow in proteins and its role in protein function. By defining the forefront of research in this area, the book delineates the current challenges and opportunities in developing novel methods and applications for the evolving study of energy flow in molecular machines and nanomaterials.

Proteins are the molecular machines of the cell, and computational modeling provides insight into how energy flow in proteins mediates protein function. The first book devoted to energy flow in proteins, this volume provides a broad overview of techniques used in the study of energy flow in biological molecules in general, in addition to its particular focus on proteins. It collects and connects a variety of computational approaches developed in distinct fields of research to reveal information central to our understanding of how proteins function, while also demonstrating methods that can be used to study energy and heat transport in condensed phase systems.
