Protein Folding Protocols presents protocols for studying and characterizing protein folding from the unfolded to the folded state. Covering experiment and theory, bioinformatics approaches, and state-of-the-art simulation protocols for better sampling of the conformational space, this volume describes a broad range of techniques to study, predict, and analyze the protein folding process. Protein Folding Protocols also provides sample approaches toward the prediction of protein structure starting from the amino acid sequence, in the absence of overall homologous sequences. These approaches have tremendous implications, ranging from drug design, functional assignment, comprehension of the nature of regulation, understanding molecular machines, viral entry into cells, and putting together cellular pathways and their dynamics. The protocols follow the successful Methods in Molecular Biology™ series format, each one offering step-by-step laboratory instructions, an introduction outlining the principle behind the technique, lists of equipment and reagents, and tips on troubleshooting and avoiding known pitfalls.
