Protein expression in a heterologous host is a cornerstone of biomedical research and of the biotechnology industry. Despite the advanced state of protein expression technology improvements are still needed. For example, membrane proteins constitute a significant percentage of the total cellular proteins but as a class are very difficult to overexpress, especially in a heterologous host. The ideal host would have the ability to express any protein, with relevant post-translational modifications, and be as easy to work with as E. coli. In Heterologous Gene Expression in E. coli: Methods and Protocols, expert scientists intimately familiar with the relevant techniques offer chapters that greatly expand the utility of this expression host. The contributions in this detailed volume describe methods, for example, to successfully express proteins in E. coli that would otherwise form aggregates in this host, to add post-translational modifications, to incorporate non-standard amino acid residues or moieties into E. coli expressed proteins, to identify binding partners, and to express membrane proteins. Written in the highly successful Methods in Molecular Biology(TM) format, chapters include introductions to their respective subjects, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Practical and cutting-edge, Heterologous Gene Expression in E. coli: Methods and Protocols seeks to familiarize the researcher with the myriad of E. coli expression strains available and move E. coli closer to that ideal of the perfect host.

50 years of DNA double helix; what was before, and afterwards

The present book, although written mainly for science students and research scientists, is also aimed at those readers who look at science, not for its own sake, but in search of a better understanding of our world in general. What were the fundamental questions asked by the early pioneers of molecular biology? What made them tick for decades, trying to elucidate the basic mechanisms of heredity and life itself? In each chapter, the development of a particular aspect of modern biology is described in a historical and logical context, not missing to take into account human aspects of the protagonists of the story. At the end of each chapter, there are some excursus with additional information, technical and otherwise, which can be read separately. The book is enriched with many illustrations, including facsimile reproductions from the original descriptions of key experiments.

In nature, biological organisms produce mineralized tissues such as bone, teeth, diatoms, and shells. Biomineralization is the sophisticated process of production of these inorganic minerals by living organisms. Construction of organic-inorganic hybrid materials with controlled mineralization analogous to those produced by nature has recently received much attention because it can aid in understanding the mechanisms of the biomineralization process and development of biomimetic materials processing. The biomineralization ? processes use aqueous solutions at temperatures below 100 C and no toxic intermediates are produced in these systems. From a serious global en- ronmental problem point of view, the development of processes inspired by biomineralization would offer valuable insights into material science and en- neering to reduce energy consumption and environmental impact. One of the most challenging scienti?c problems is to gain greater insight into the mol- ular interactions occurring at the interface between the inorganic mineral and the macromolecular organic matrix. Model systems are often regarded as a straight-forward experimental approach toward biomimetic crystallization. Hierarchical architectures consisting of small building blocks of inorganic cr- tals are often found in biominerals. Studies of nanocrystal self-organization in solution systems would also be helpful for understanding biomineralization. In these volumes, we focus on construction of organic-inorganic hybrid - terials with controlled mineralization inspired by natural biomineralization. In the?rst volume, thereader will ?nd contributionsproviding abasic scopeof the mineralization process in aqueous solution.

Del Rio's research group focuses on the metabolism of reactive oxygen species (ROS), reactive nitrogen species (RNS) and antioxidants in plant peroxisomes, and the ROS- and RNS-dependent role of peroxisomes in plant cell signalling. The editor Michael Schrader is Professor of Cell Biology & Cytopathology in the Department of Biosciences at the University of Exeter, UK. Using mammalian peroxisomes as model organelles, Prof. Schrader and his team aim to unravel the molecular machinery and signalling pathways that mediate and regulate the formation, dynamics and abundance of these medically relevant cellular compartments.

The present monograph is devoted to the chemistry of nitroazoles, one of the most interesting series of heteroaromatic compounds. The azoles hold a special position in the chemistry of heterocycles. Their unique properties and specific biological activity attract much attention of research chemists all over the world. During the last years the interest in the chemistry of nitroazoles has increasing. The nitro derivatives of azoles have found a wide application in various fields of industrial chemistry, agriculture, and medicine. Medical products developed by nitroazoles incluce a- mycin, metronidazole, misonidazole, tinidazole, nitazole, etc. , ionic liquids, hi- energy materials, synthons for nanocompounds, universal bases in peptide nucleic acids, plant growth regulators, and intermediates for organic synthesis. The investigations in the field of energetic compounds have received enormous interest in recent years. Energetic materials on the base nitroazoles - explosives, propellants, and pyrotechnics - are widely used for both civilian and military applications. Nitroazoles, especially polynitroazoles, possess higher heat of for- tion, density, and oxygen balance than their carbocyclic analogs. A number of ongoing research programs worldwide are aimed for the development of new explosives and propellants with higher performance characteristics or enhanced insensitivity to thermal or shock insults and pyrotechnics with reduced smoke. The preparation of nitroazoles demonstrates its great synthetic potential. At the same time, feasibility and availability of the starting molecules make this strategy a p- erful method for high-energy material construction.
