This book addresses the most recent advances in the transport of proteins across a variety of biological membranes. In addressing this topic, this volume includes several new twists not previously addressed in the literature. In the last few years, the study of protein translocation has been revolutionized by the availability of structural information on many of the components and complexes involved in the process. Unlike earlier books written on protein translocation, this volume considers these advances. In addition, several chapters discuss facets of protein translocation from a systems biology perspective, considered by many to be the next paradigm for biological study. Readers of this book will
