An introduction to underlying principles and experimental procedures using the newest strategies and techniques for obtaining extensive NMR assignments in biopolymers based on NMR data and the primary structure. Includes an extensive and non-mathematical discussion of 2D NMR and Nulcear Overhauser effects; resonance assignments and structure determination in proteins; and resonance assignments and structure determination in nucleic acids. Enables specialists and non-specialists to evaluate the potentialities and limitations of the method. Read more Read less.
Proton nuclear magnetic resonance was used to study individual molecules of hydration water bound to the protein basic pancreatic trypsin inhibitor BPTI and to the nonapeptide oxytocin in aqueous solution. The experimental observations are nuclear Overhauser effects NOE between protons of individual amino acid residues of the protein and those of hydration water. The studies show that there are two qualitatively different types of hydration sites. Four water molecules in the interior of the BPTI molecule are in identical locations in the crystal structure and in solution. Short residence times prevail for all surface hydration sites, independent of whether or not they are occupied by well ordered, X-ray observable water in the protein single crystals.
NMR of proteins and nucleic acids
By Jason Socrates Bardi. Even with the most powerful and sensitive of modern nuclear magnetic resonance NMR instruments, many interesting systems are impossible to solve because they are simply too big. And structural biologists have sought for ways in which to breach, stretch, surpass, or otherwise blow away this size limitation. Some biologists have wanted to do this for decades. Proteins in solution are constantly bombarded with solvent molecules and undergo random "Brownian" motion as a result. The larger the structure is, the more slowly it will respond to the impact and the more slowly it will reorient itself in solution. This slow response deteriorates NMR spectra and makes structure determination impossible.

Nuclear magnetic resonance spectroscopy of proteins usually abbreviated protein NMR is a field of structural biology in which NMR spectroscopy is used to obtain information about the structure and dynamics of proteins , and also nucleic acids , and their complexes. The field was pioneered by Richard R. Structure determination by NMR spectroscopy usually consists of several phases, each using a separate set of highly specialized techniques. The sample is prepared, measurements are made, interpretive approaches are applied, and a structure is calculated and validated. NMR involves the quantum-mechanical properties of the central core " nucleus " of the atom. These properties depend on the local molecular environment, and their measurement provides a map of how the atoms are linked chemically, how close they are in space, and how rapidly they move with respect to each other. These properties are fundamentally the same as those used in the more familiar magnetic resonance imaging MRI , but the molecular applications use a somewhat different approach, appropriate to the change of scale from millimeters of interest to radiologists to nanometers bonded atoms are typically a fraction of a nanometer apart , a factor of a million.

The recommendations presented here are designed to support easier communication of NMR data and NMR structures of proteins and nucleic acids through unified nomenclature and reporting standards. Much of this document pertains to the reporting of data in journal articles; however, in the interest of the future development of structural biology, it is desirable that the bulk of the reported information be stored in computer-accessible form and be freely accessible to the scientific community in standardized formats for data exchange. The Task Group has reviewed previous formal recommendations and has extended them in the light of more recent developments in the field of biomolecular NMR spectroscopy.
The authors wish it to be known that, in their opinion, the first two authors should be regarded as Joint First Authors. Nuclear magnetic resonance NMR spectroscopy is a method of choice to study the dynamics and determine the atomic structure of macromolecules in solution. To ultimately provide a perfectly transparent and easy to use service, we designed an online user interface to ARIA with additional functionalities. Protein structure determination is crucial for understanding protein function, as it paves the way to the discovery of new drugs and of new approaches to control pathological biological processes. The recent advances in structural biology now allow collecting structural information from a variety of techniques at various resolutions 1.
В какую-то долю секунды сознание Беккера засекло очки в металлической оправе, обратилось к памяти в поисках аналога, нашло его и, подав сигнал тревоги, потребовало принять решение. Он отбросил бесполезный мотоцикл и пустился бежать со всех ног. К несчастью для Беккера, вместо неуклюжего такси Халохот обрел под ногами твердую почву.
