This book discusses the paradigm-shifting phenomenon of intrinsically disordered proteins (IDPs) and hybrid proteins containing ordered domains and functional IDP regions (IDPRs). The properties of IDPs and IDPRs are highly complementary to those deriving from the presence of a unique and well-defined three-dimensional fold. Ignored for a long time in high-resolution studies of proteins, intrinsic protein disorder is now recognized as one of the key features for a large variety of cellular functions, where structural flexibility presents a functional advantage in terms of binding plasticity and promiscuity and this volume explores this exciting new research. Recent progress in the field has ...
NMR is a growing technique which represents a generalized, spread, common tool for spectroscopy and for structural and dynamic investigation. Part of the field of competence of NMR is represented by molecules with unpaired electrons, which are called paramagnetic. The presence of unpaired electrons is at the same time a drawback (negative effect) and a precious source of information about structure and dynamics. New phenomena and effects are described which are due to the high magnetic fields and advances in the methodology. Solution NMR of Paramagnetic Molecules is unique in dealing with these matters. The scope is that of presenting a complete description, which is both rigorous and pictorial, of theory and experiments of NMR of paramagnetic molecules in solution. Pertinent examples are described. From the time dependent behaviour of electrons in the various metal ions including polimetallic systems to the hyperfine-based information, and from NMR experiments to constraints for solution structure determination. The book's major theme is how to perform high resolution NMR experiments and how to obtain structural and dynamic information on paramagnetic metal ion containing systems.
Nuclear magnetic resonance (NMR) is an analytical tool used by chemists and physicists to study the structure and dynamics of molecules. In recent years, no other technique has gained such significance as NMR spectroscopy. It is used in all branches of science in which precise structural determination is required and in which the nature of interactions and reactions in solution is being studied. Annual Reports on NMR Spectroscopy has established itself as a premier means for the specialist and non-specialist alike to become familiar with new techniques and applications of NMR spectroscopy. - This volume of Annual Reports on NMR Spectroscopy focuses on the analytical tool used by chemists and physicists and inlcudes topics such as Profiling of Food Samples, Recent Advances in Solution NMR Studies and Magic Angle Spinning NMR Studies of Protein Assemblies
Since A. Kowalsky's first report of the spectrum of cytochrome c in 1965, interest in the detection, assignment and interpretation of paramagnetic molecules has surged, especially in the last decade. Two classes of systems have played a key role in the development of the field: heme proteins and iron-sulfur proteins. These two systems are unique in many respects, one of which is that they contain well-defined chromophores, each of which can be studied in detail outside the protein matrix. They are the most successfully studied macromolecules, and the first eight and last six of the seventeen contributions to this book deal with heme and/or iron-sulfur proteins. The middle three chapters survey the progress on, and significant promise of, more difficult systems which do not possess a chromophore, but which have nevertheless yielded remarkable insights into their structure.

In this brief, Vladimir Uversky discusses the paradigm-shifting phenomenon of intrinsically disordered proteins (IDPs) and hybrid proteins containing ordered domains and functional IDP regions (IDPRs). Beginning with an introduction to the concept of protein intrinsic disorder, Uversky then goes on to describe the peculiar amino acid sequences of IDPs, their structural heterogeneity, typical functions and disorder-based binding modes. In the final sections, Uversky discusses IDPs in human diseases and as potential drug targets. This volume provides a snapshot to researchers entering the field as well as providing a current overview for more experienced scientists in related areas.
A wide range of researchers are currently investigating different properties and applications for copper-containing proteins. Biochemists researching metal metabolism in organisms ranging from bacteria to plants to animals are working in a completely different area of discovery than scientists studying the transportation and regulation of minerals and small molecule nutrients. They are both working with copper-containing proteins, but in very different ways and with differing anticipated outcomes.
In 1911, the Nobel Prize for Chemistry was awarded to Marie Curie, eight years after she had received the Nobel Prize for Physics. An extraordinary scientific adventure ended, and the deification of an iconic character and symbol of the amazing transformations of costume which would characterize the following decades began to take root. During the transfer of the Curies' remains to the Pantheon, Pierre Gilles de Gennes wanted to underline Marie's "beauty of self-denial". The Christmas Lecture pays tribute to the dual inheritance which she left us: the strength of scientific rationality against the obscurantism of beliefs and gender equality. The conference traces the most relevant aspects of Marie Curie's life, sharing her extraordinary scientific discoveries, but also underlining socio-cultural and customary aspects and highlighting the historical context of an era which was tumultuously changing.
