This SpringerBriefs series presents concise summaries of key ideas in protein folding and structure. Prepared by leading experts, the series contains two types of volumes. “Snapshot” volumes allow fast entry to a general topic in protein folding and structure. These volumes cover fundamental concepts and methodologies in the context of contemporary research and are ideal for newcomers to the field. The second type of volume focuses on a specific topic within the area of protein folding and structure. These volumes are aimed at researchers working in the specialist field but can also be useful for scientists and students in related areas. Through these compact volumes of 50 to 125 pages, this series serves as a venue for publication between typical research papers, review articles and full books.
