Power Laws, Scale-free Networks and Genome Biology deals with crucial aspects of the theoretical foundations of systems biology, namely power law distributions and scale-free networks which have emerged as the hallmarks of biological organization in the post-genomic era. The chapters in the book not only describe the interesting mathematical properties of biological networks but moves beyond phenomenology, toward models of evolution capable of explaining the emergence of these features. The collection of chapters, contributed by both physicists and biologists, strives to address the problems in this field in a rigorous but not excessively mathematical manner and to represent different viewpoints, which is crucial in this emerging discipline. Each chapter includes, in addition to technical descriptions of properties of biological networks and evolutionary models, a more general and accessible introduction to the respective problems. Most chapters emphasize the potential of theoretical systems biology for discovery of new biological phenomena.

This thesis describes research into the mode of function, inhibition, and evolution of the ribosomal catalytic center, the Peptidyl Transferase Center (PTC)--research that has already led to attempts at improving PTC antibiotics. The PhD candidate carried out two parallel studies. One using a combination of X-ray crystallography, biochemistry, molecular biology, and theoretical studies to obtain crystal structures of ribosomal particles with antibiotics that target the PTC, revealing the modes of action, resistance, cross-resistance and discrimination between ribosomes of eubacterial pathogens and eukaryotic hosts. In the second parallel study, the candidate synthesized a ribosomal substructure--one that may represent the minimal entity capable of catalyzing peptide bond formation--shedding light on the origin of the ribosome itself.

Upon completion of the human genome project over 800 G protein-coupled receptor 1 (GPCR) genes, subdivided into five categories, were identified. These receptors sense a diverse array of stimuli, including peptides, ions, lipid analogues, light and odour, in a discriminating fashion. Subsequently, they transduce a signal from the ligand-receptor complex into numerous cellular responses. The importance of GPCRs is further reflected in the fact that they constitute the most common target for therapeutic drugs across a 2 wide range of human disorders. Phylogenetic analysis of GPCRs produced the GRAFS classification system, which subdivides GPCRs into five discrete families: glutamate, rhodopsin, adhesion, frizzled/taste2 and secretin receptors. The adhesion-GPCR family 2 can be further subdivided into eight groups. The field of adhesion-GPCR biology has indeed become large enough to require a volume dedicated solely to this field. The contributors to this book have made a courageous effort to address the key concepts of adhesion-GPCR biology, including the evolution and biochemistry of adhesion-GPCRs; there are extensive discussions on the functional nature of these receptors during development, the immune response and tumourgenesis. Finally, there are chapters dedicated to adhesion-GPCR signalling, an area of intense investigation.

In the early 1980s, a few scientists started working on a Xenopus transcription factor, TFIIIA. They soon discovered a novel domain associated with zinc, and named this domain "zinc finger. " Th e number of proteins with similar zinc fingers grew quickly and these proteins are now called C2H2, Cys2His2 or classical zinc finger proteins. To date, about 24,000 C2H2 zinc finger proteins have been recognized. Approximately 700 human genes, or more than 2% of the genome, have been estimated to encode C2H2 finger proteins. From the beginning these proteins were thought to be numerous, but no one could have predicted such a huge number. Perhaps thousands of scientists are now working on C2H2 zinc finger proteins fi-om variou s viewpoints. This field is a good example of how a new science begins with the insight of a few scientists and how it develops by efforts of numerous independent scientists, in contrast to a policy-driven scientific project, such as the Human Genome Project, with goals clearly set at its inception and with work performed by a huge collaboration throughout the world. As more zinc finger proteins were discovered, several subfamilies, such as C2C2, CCHC, CCCH, LIM, RING, TAZ, and FYVE emerged, increasing our understanding of zinc fingers. The knowledge was overwhelming. Moreover, scientists began defining the term "zinc finger" differently and using various names for identical zinc fingers. These complications may explain why no single comprehensive resource of zinc finger proteins was available before this publication.

In recent years remarkable progress has been accomplished with respect to our knowledge about bacterial protein toxins.

Quantitative Proteomics by Mass Spectrometry, from the Methods in Molecular Biology series, is a compendium of cutting-edge protocols for quantitative proteomics, and presents the most significant methods used in the field today. The focus on mass spectrometry (MS) is integral, as MS has, and will continue to be, an essential tool in proteomics for studying complex biological systems and human diseases. This volume, written and compiled by leading quantitative proteomic experts, is an indispensable resource in the search for novel biomarkers.
Quantitative Proteomics by Mass Spectrometry presents several innovative MS quantitative procedures, including a variety of methods for introducing isotopic labels and quantifying post-translational modifications. Some of these methods include growing an organism in isotope-enriched media, performing trypsin proteolysis in the presence of 18O-water, reacting protein samples with isotopically labeled reagents, quantifying relative amount of proteins without the use of any isotopic labels. Attention is also given to state-of-the-art techniques for the characterization of the phosphoproteome and tandem MS for detection of inborn errors of metabolism. Specifically, the procedure for determinations of enzymatic activity could be used for large-scale screening of newborns. The protocols in this volume expand both the breadth and depth of readily available methods for quantitative proteomic researchers using MS.

One ofthe major drivers in biological research is the establishment ofstructures and functions of the 50,000 or so proteins in our bodies. Each has a characteristic- dimensional structure, highly "ordered" yet "disordered"! This structure is essential for a protein's function and, significantly, it must be sustained in the competitive and complex environment of the living cell. It is now being recognised that when a cell loses control, proteins can se- assemble into more complex supermolecular structures such as the amyloid fibres and plaques associated with the pathogenesis of prion (CJD) or age-related (Alzheimer's) diseases. This is a pointer to the wider significance of the self-assembling properties of polypeptides. It has been long known that, in silk, polypeptides are assembled into- sheet structures which impart on the material its highly exploitable properties of flexibility combined with high tensile strength. But only now emerging is the recognition that peptides can Self-assemble into a wide variety of non-protein-like structures, including fibrils, fibres, tubules, sheets and monolayers. These are exciting observations and, more so, the potential for materials and medical exploitations is so wide ranging that over 80 scientists from Europe, USA, Japan and Israel. met 1-6 July 1999 in Crete, to discuss the wide-ranging implications of these novel developments. There was a spirit of excitement about the workshop indicative of an important new endeavor. The emerging perception is that of a new class of materials set to become commercially viable early in the 21st century.
