The SecretoryPathway The transport ofproteins and lipids from their site ofsynthesis at the endoplasmic reticu­ lum (ER) to the cellsurface ismediated by the secretory pathway and isan essential process in eukaryotic organisms. A great variety ofmolecules are extruded from cellsby the action ofthe secretory pathway, including extracellular matrix components that provide the foundation for constructing tissuesand organs. Moreover, this pathway playsa major role in the biogenesisof the plasma membraneand itsexpansion before celldivision. Therefore, withoutsecretion there would be no cells,tissuesor organs, and so it issafeto saythat we oweourvery existence to the secretory pathway. To understand the process ofsecretion we must learn about the organelles that compose the secretory pathway; the ER and Golgi apparatus, and the transport vesicles these or­ ganelles produce. The membrane ofthese organelles is primarily synthesized and assembled at the ER but with contributions from mitochondria (phosphatidylethanolamine) and the Golgi apparatus (sphingolipids). Newly synthesized proteins destined for secretion gain en­ try into the secretory pathway by translocation across the ER membrane. This translocation apparatus also integrates proteins into the membrane and establishes their topology with respect to the lipid bilayer (seeChapter 7). Many secretory proteins are covalently modified with oligosaccharides to produce glycoproteins, a biosynthetic process initiated in the ER and continued in the Golgi apparatus. Once proteins are properly folded and modified in the ER, they are allowed to leave and are ushered into COPlI-coated carrier vesiclesforming at specific exit sites (see Chapters 1 and 8).

Fundamentals of Protein Structure and Function Engelbert Buxbaum, Dr. rer. nat. This book serves as an introduction to the fundamentals of protein structure and function. Starting with their make up from simple building blocks called amino acids, the 3-dimensional structure of proteins is explained. This is followed by an introduction into enzymology and modern concepts of enzyme kinetics, taking into account the physiological and medical significance of this often neglected topic. Also covered in the text are enzymes, biocatalysts, enzyme kinetics, hemoglobin, myoglobin, prion proteins, immunoproteins, motor proteins and movement, cell-cell interactions, molecular chaperones and chaperonins, transport of proteins into mitochondria, transport of proteins between cell compartments, transport of solutes across membranes, analytic techniques, protein-ligand interactions, protein purification, and protein structure, size and shape, emphasizing the link between protein structure, physiological function and medical significance. This book is an introductory text for researchers in protein biochemistry, molecular biology, cell biology, chemistry, biophysics and biomedical research. The book also makes an ideal textbook for graduate and advanced undergraduate courses in protein structure and function, and a supplementary text for related courses. About the Author Dr. Buxbaum is a biochemist with interest in enzymology and protein science. Dr. Buxbaum has been working on the biochemistry of membrane transport proteins for almost 20 years and has taught courses in biochemistry and molecular medicine at several universities. "The analytical descriptions of structure, biophysics and function of proteins is an extremely important aspect of today's education in biochemistry." Martin Sagermann, Ph.D. University of California, Santa Barbara

The adsorption of proteins at interfaces plays a role in many ?elds, such as health, food, environment and analysis. Fundamental aspects are useful when considering applications. We focus here especially on solid-liquid interfaces and present a few fundamental studies regarding adsorption - netics and conformational changes, and examples of applications to sensors and membranes. The ?rst part is dedicated to fundamental studies performed using - tical waveguide lightmode spectroscopy, as an example of a technique that has the advantage of not requiring labelled proteins, but is limited to s- ci?c supports. Conversely, the radiolabelling of proteins, which has the disadvantage of any labelling process, allows application to any kind of s- faces. As proteins bear both positive and negative charges, we can expect thein?uenceofanelectric?eldnormaltothe interfaceonthe pack- ing order at interfaces. The re?ning of data treatment may also lead to the determination of useful structural parameters. The balance between protein-surface and protein-protein interactions is a key point for the - scription of the structure at high coverage of the surface. Electrokinetic methods, like measurement of the streaming potential, may be helpful in the electrical characterisation of the interfacial layer facing the solution. The second part includes different bench techniques that were dev- oped to improve the sensitivity of the characterisation of the orientation and structure of the proteins at interfaces: dual polarisation interferometry and total internal re?ection ellipsometry are such recent examples.

Volume one of this two volume sequence focuses on the basic characterization of known protein structures as well as structure prediction from protein sequence information. The 11 chapters provide an overview of the field, covering key topics in modeling, force fields, classification, computational methods, and struture prediction. Each chapter is a self contained review designed to cover (1) definition of the problem and an historical perspective, (2) mathematical or computational formulation of the problem, (3) computational methods and algorithms, (4) performance results, (5) existing software packages, and (6) strengths, pitfalls, challenges, and future research directions.
