Book excerpt: Lasso peptides form a growing family of fascinating ribosomally-synthesized and post-translationally modified peptides produced by bacteria. They contain 15 to 24 residues and share a unique interlocked topology that involves an N-terminal 7 to 9-residue macrolactam ring where the C-terminal tail is threaded and irreversibly trapped. The ring results from the condensation of the N-terminal amino group with a side-chain carboxylate of a glutamate at position 8 or 9, or an aspartate at position 7, 8 or 9. The trapping of the tail involves bulky amino acids located in the tail below and above the ring and/or disulfide bridges connecting the ring and the tail. Lasso peptides are subdivided into three subtypes depending on the absence (class II) or presence of one (class III) or two (class I) disulfide bridges. The lasso topology results in highly compact structures that give to lasso peptides an extraordinary stability towards both protease degradation and denaturing conditions. Lasso peptides are generally receptor antagonists, enzyme inhibitors and/or antibacterial or antiviral (anti-HIV) agents. The lasso scaffold and the associated biological activities shown by lasso peptides on different key targets make them promising molecules with high therapeutic potential. Their application in drug design has been exemplified by the development of an integrin antagonist based on a lasso peptide scaffold. The biosynthesis machinery of lasso peptides is therefore of high biotechnological interest, especially since such highly compact and stable structures have to date revealed inaccessible by peptide synthesis. Lasso peptides are produced from a linear precursor LasA, which undergoes a maturation process involving several steps, in particular cleavage of the leader peptide and cyclization. The post-translational modifications are ensured by a dedicated enzymatic machinery, which is composed of an ATP-dependent cysteine protease (LasB) and a lactam synthetase (LasC) that form an enzymatic complex called lasso synthetase. Microcin J25, produced by Escherichia coli AY25, is the archetype of lasso peptides and the most extensively studied. To date only around forty lasso peptides have been isolated, but genome mining approaches have revealed that they are widely distributed among Proteobacteria and Actinobacteria, particularly in Streptomyces, making available a rich resource of novel lasso peptides and enzyme machineries towards lasso topologies.

Available in PDF, EPUB and Kindle. Book excerpt: Free energy constitutes the most important thermodynamic quantity to understand how chemical species recognize each other, associate or react. Examples of problems in which knowledge of the underlying free energy behaviour is required, include conformational equilibria and molecular association, partitioning between immiscible liquids, receptor-drug interaction, protein-protein and protein-DNA association, and protein stability. This volume sets out to present a coherent and comprehensive account of the concepts that underlie different approaches devised for the determination of free energies. The reader will gain the necessary insight into the theoretical and computational foundations of the subject and will be presented with relevant applications from molecular-level modelling and simulations of chemical and biological systems. Both formally accurate and approximate methods are covered using both classical and quantum mechanical descriptions. A central theme of the book is that the wide variety of free energy calculation techniques available today can be understood as different implementations of a few basic principles. The book is aimed at a broad readership of graduate students and researchers having a background in chemistry, physics, engineering and physical biology.

Available in PDF, EPUB and Kindle. Book excerpt: "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.

Book excerpt: In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition of mechanisms of protein folding in 1994, significant advances in both the technical and conceptual understanding of protein folding. This new edition has been brought up to date in content, context, and authorship and will make the subject accessibleto a wide range of scientists. The emphasis on experimental approaches has benn maintained from the first edition but this time within the explicit context of simulations and energy surfaces. There is an introductory chapter explaining the 'new' model of protein folding, which takes into account theheterogeneity of the starting state. Advances in interpreting observed kinetic data and the development of technology to observe fast folding reactions and characterize intermediate structures have accompanied this new view and are covered in detail. The term 'molten globule'is often usedincorrectly but here the significance of the term is carefully described at different satges of folding. The concept of the transition state, including the complementary approaches of molecular dynamics and protein engineering, is also discussed in detail. In vitro studies provide the molecularbasis for the thermodynamic and kinetic energy minimization of the in vivo processes of protein folding and two of the potentially rate determining reactions are disulphide bond formation and proline isomerization. It has also become increasingly apparent that chaperone proteins play a vital role inprotein folding and other reactions of proteins involoving major conformational change and the molecular details of these processes are discussed in detail in chapter 14. The final chapter describes the centreal importance of protein folding and unfolding reactions in disease and gives claerdefinition of the term 'misfolding'. Studying protein folding in vivo is full of problems and to show how these problems can be overcome in practice, three case studies of three very different types of protein have been included: the small globular protein apomyoglobin; the fibrous protein collagen;and the membrane protein haemagglutinin.
