Proteomics - the analysis of the whole set of proteins and their functions in a cell - is based on the revolutionary developments which have been achieved in protein analysis during the last years. The number of finished genome projects is growing and in parallel there is a dramatically increasing need to identify the products of revealed genes. Acting on a micro level modern protein chemistry increases our understanding of biological events by elucidating the relevant structure-function relationships. The second edition of the successful title Microcharacterization of Proteins presents a current overview of modern protein analysis: From sample preparation to sequence analysis, mass spectrometry and bioinformatics it informs about the tools needed in protein research. This makes the book indispensable for everyone involved in proteomics!

Milestones in the techniques and methodology of polypeptide structure determination include the determination of the sequence of insulin by Sanger in 1951 (I) and the introduction of the repeti tive degradation of proteins with phenylisothiocyanate by Edman in 1959 (2). The automation of Edman chemistry (3) played a major role in the determination of polypeptide structures. Important modifications of Edman chemistry include the solid-phase approach by Laursen in 1971 (4) and the use of modified Edman reagents such as 4-N, N-dimethylaminoazobenzene-4'-isothiocy- ate (DABITC) for manual sequencing by Chang et al. (5) in 1976. A second major breakthrough in the analysis of polypeptides was automated amino acid analysis described by Spackman et al. in 1958 (6). However, during the period from 1975 to 1980, it became increasingly clear that the amount of material required for struc tural analysis was more than could be easily isolated for the vast majority of proteins. The field was criticized for its lack of sensitive techniques for the analysis of growth factors, immune modulators, membrane receptors, and peptide hormones. In addition, very little had been done to modernize and improve the original instruments introduced in the mid-1960s. The first indications of improved instrumentation for Edman chemistry came from Wittmann-Liebold's laboratory (7), followed by the introduction of a "micro" sequencer by Hunkapiller and Hood in 1978 (8). The movement toward improved instrumentation culminated in the "gas"--Phase sequencer of Hewick et al. (9) in 1981

Both a thorough introduction and laboratory guide! This book is based on the lectures and demonstrations presented at a successful workshop organized by the authors. Expert contributions and the support of more than a dozen companies engaged in bioanalysis and instrumentation enabled the participants to familiarize themselves with the most recent developments e.g. in protein separation and characterization (including laser desorption-ionisation mass spectrometry), fragmentation and micro sequencing. The workshop was held in the Max Planck Institute for Biochemistry at Martinsried. It helped graduate students and researchers from academia and industry both to understand and apply themselves the most sophisticated methods available. This book offers a stimulating combination of basic concepts and practical applications - and is thus useful at all levels.

This text is devoted to the characterization of recombinant DNA-derived proteins by peptide mapping. It describes new technological procedures including capillary electrophoresis, analysis of glycopeptides and the use of electrospray and matrix-assisted laser desorption mass spectrometry. The book presents practical procedures for preparing a protein sample, the enzyme digestion, choice of separation method and procedures for the structural analysis of the separated species. Many figures of peptide maps illustrate typical results. Tables of summary information about digestion, separation conditions, and analyses of important protein samples are also presented.

"Protein Structure Analysis - Preparation and Characterization" is a compilation of practical approaches to the structural analysis of proteins and peptides. Here, about 20 authors describe and comment on techniques for sensitive protein purification and analysis. These methods are used worldwide in biochemical and biotechnical research currently being carried out in pharmaceu tical and biomedical laboratories or protein sequencing facilities. The chapters have been written by scientists with extensive ex perience in these fields, and the practical parts are well documen ted so that the reader should be able to easily reproduce the described techniques. The methods compiled in this book were demonstrated in student courses and in the EMBO Practical Course on "Microsequence Analysis of Proteins" held in Berlin September 10-15, 1995. The topics also derived from a FEBS Workshop, held in Halkidiki, Thessaloniki, Greece, in April, 1995. Most of the authors participated in these courses as lecturers and tutors and made these courses extremely lively and successful. Since polypeptides greatly vary depending on their specific structure and function, strategies for their structural analysis must for the most part be adapted to each individual protein. Therefore, advantages and limitations of the experimen tal approaches are discussed here critically, so that the reader becomes familiar with problems that might be encountered.

Proteins are the servants of life. They occur in all component parts of living organisms and are staggering in their functional var- ty, despite their chemical similarity. Even the simplest single-cell organism contains a thousand different proteins, fulfilling a wide range of life-supporting roles. Their production is controlled by the cell’s genetic machinery, and a malfunction of even one protein in the cell will give rise to pathological symptoms. Additions to the total number of known proteins are constantly being made on an increasing scale through the discovery of mutant strains or their production by genetic manipulation; this latter technology has become known as protein engineering. The in vivo functioning of proteins depends critically on the chemical structure of individual peptide chains, but also on the detailed folding of the chains themselves and on their assembly into larger supramolecular structures. The molecules and their fu- tional assemblies possess a limited in vitro stability. Special methods are required for their intact isolation from the source material and for their analysis, both qualitatively and quantitatively. Proteins are also increasingly used as “industrial components,” e.g., in biosensors and immobilized enzymes, because of their specificity, selectivity, and sensitivity. This requires novel and refined proce- ing methods by which the protein isolate can be converted into a form in which it can be utilized.

With the development of genomics, separation technology and mass spectrometry, proteomics has become an important tool in biological research. Characterization of posttranslational modification (PTM) by mass spectrometry is attracting an increasing attention because of its importance in signal transduction and the difficulty in obtaining this information from genomic methods. Bottom-up methods, which analyze the peptides from enzymatic digestion of proteins, are widely used for proteomic research. However, bottom-up methods may lose some important information when characterizing PTM since not all peptides are detected. In contrast, top-down methods directly characterize intact proteins, which makes it possible to retain PTM information. This dissertation focuses on the characterization of proteins by coupling high throughput methods, capillary isoelectric focusing electrophoresis (CIEF) and electrospray ionization (ESI) mass spectrometry (MS). In this work, a CIEF-RPLC-ESIMS system is designed and constructed for 2-D profiling of protein mixture. The microdialysis membrane based cathodic cell used in this system not only serves as the cathodic cell in CIEF separation, but also transfers the focused proteins separated by CIEF to RPLC. After eliminating the interference of ampholyte, a few fmol of protein can be detected with this system. The detection limit of this system is one order of magnitude lower than 2-D PAGE. By taking the advantage of high resolving power with mass spectrometry and multidimensional separation, the theoretical peak capacity of this system can reach 1x10 6, which is two orders of magnitude higher than theoretical peak capacity of 2-D PAGE. This system is firstly tested with a standard protein mixture. After slight modification, this system is used to profile the intact protein from a yeast enzyme concentrate and a lysate of the green sulfur bacterium Chlorobium tepidum. The pI vs. MW profile obtained from CIEF-RPLC-MS compares favorably with theoretical data derived from C. tepidum genome and experimental data obtained from 2-D-PAGE.
