This book discusses how biological molecules exert their function and regulate biological processes, with a clear focus on how conformational dynamics of proteins are critical in this respect. In the last decade, the advancements in computational biology, nuclear magnetic resonance including paramagnetic relaxation enhancement, and fluorescence-based ensemble/single-molecule techniques have shown that biological molecules (proteins, DNAs and RNAs) fluctuate under equilibrium conditions. The conformational and energetic spaces that these fluctuations explore likely contain active conformations that are critical for their function. More interestingly, these fluctuations can respond actively to external cues, which introduces layers of tight regulation on the biological processes that they dictate. A growing number of studies have suggested that conformational dynamics of proteins govern their role in regulating biological functions, examples of this regulation can be found in signal transduction, molecular recognition, apoptosis, protein / ion / other molecules translocation and gene expression. On the experimental side, the technical advances have offered deep insights into the conformational motions of a number of proteins. These studies greatly enrich our knowledge of the interplay between structure and function. On the theoretical side, novel approaches and detailed computational simulations have provided powerful tools in the study of enzyme catalysis, protein / drug design, protein / ion / other molecule translocation and protein folding/aggregation, to name but a few. This work contains detailed information, not only on the conformational motions of biological systems, but also on the potential governing forces of conformational dynamics (transient interactions, chemical and physical origins, thermodynamic properties). New developments in computational simulations will greatly enhance our understanding of how these molecules function in various biological events.

"As key effector units of the cell, understanding structure and function relationships of proteins are integral to explaining physiology and, in turn, pathophysiology. With the cost of drug development soaring and success dwindling, new ways to probe protein function will be at the forefront of innovation. A protein's function is the product of its conformational dynamics, where distinct 3-dimensional conformations of a protein dictate its various effects on the cell. Though highly valuable technologies capable of reporting on protein conformation currently exist, X-ray crystallography and nuclear magnetic resonance among others, their capacity to report on dynamic events and/or in physiologically relevant assay conditions are limited.This thesis describes the development and application of biosensors capable of reporting on protein conformation in live human cells. Biosensors were developed for two classes of protein targets, ion channels - Kir3, and G protein-coupled receptors (GPCR) - FP and AT1R, together representing the targets of a majority of current prescription drugs. The biosensor design was based on bioluminescence resonance energy transfer (BRET) and required the insertion of a bioluminescent protein and a short peptide sequences within the protein of interest. Due to the specific affinity for the peptide sequence of an organic fluorophore, fluorescein biarsenical hairpin binder (FlAsH), the latter could be used as a resonance energy transfer acceptor to probe the different conformations of the protein of interest without disrupting its function.Both panels of biosensors successfully reported on ligand-induced conformational rearrangements in the target proteins and correlated with functional effects. The GPCR biosensors were further applied to enrich our understanding of receptor dimerization and allosteric communication between proteins, in this case, the FP/AT1R heterodimer." --

Understanding the conformational dynamics of biological macromolecules at atomic resolution remains a grand challenge at the intersection of biology, chemistry, and physics. Molecular dynamics (MD) -- which refers to computational simulations of the atomic-level interactions and equations of motions that give rise to these dynamics -- is a powerful approach that now produces immense quantities of time series data on the dynamics of these systems. Here, I describe a variety of new methodologies for analyzing the rare events in these MD data sets in an automatic, statically-sound manner, and constructing the appropriate simplified models of these processes. These techniques are rooted in the theory of reversible Markov chains. They include new classes of Markov state models, hidden Markov models, and reaction coordinate finding algorithms, with applications to protein folding and conformational change. A particular focus herein is on methods for model selection and model comparison, and computationally efficient algorithms.

Given the immense progress achieved in elucidating protein-protein complex structures and in the field of protein interaction modeling, there is great demand for a book that gives interested researchers/students a comprehensive overview of the field. This book does just that. It focuses on what can be learned about protein-protein interactions from the analysis of protein-protein complex structures and interfaces. What are the driving forces for protein-protein association? How can we extract the mechanism of specific recognition from studying protein-protein interfaces? How can this knowledge be used to predict and design protein-protein interactions (interaction regions and complex structures)? What methods are currently employed to design protein-protein interactions, and how can we influence protein-protein interactions by mutagenesis and small-molecule drugs or peptide mimetics?The book consists of about 15 review chapters, written by experts, on the characterization of protein-protein interfaces, structure determination of protein complexes (by NMR and X-ray), theory of protein-protein binding, dynamics of protein interfaces, bioinformatics methods to predict interaction regions, and prediction of protein-protein complex structures (docking and homology modeling of complexes, etc.) and design of protein-protein interactions. It serves as a bridge between studying/analyzing protein-protein complex structures (interfaces), predicting interactions, and influencing/designing interactions.
