Goals / Objectives
Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique that provides atomic level characterization of the solution structure of small and large molecules. As such, it is important in the understanding of life processes at the molecular level. In agriculture, the applications of NMR spectroscopy are as varied as the studies involving molecular structure and conformational analysis. NMR spectroscopy is frequently carried out in solution, but some NMR techniques are used for the characterization of biochemical processes. Standardized NMR instruments have made these techniques easily accessible to non-expert scientists. So, the overall objective is to provide service to faculty so they can incorporate this technique into their research programs here at the University of Minnesota. This service would include consultation and preliminary interpretation for potential NMR users, the training of long-time users, running samples and production of refined NMR spectra for all users. Researchers from 15 different departments on the St Paul campus of the University of Minnesota have previously used the facility. A newly acquired 400MHz NMR has replaced the obsolescent 300 MHz NMR which was retired from the facility in 2009. Projects presently using the instrument include research from Drs. Adrian Hegeman and Jerry Cohen (Horticulture), Dr. Devin Peterson (Food Science and Nutrition), Dr Michael Sadowsky (Soil Science), Drs. Larry Wackett, Romas Kazlauskas and Jack Richman(Biochemistry) and Dr Steve Heilman (BioTechnology Institute).
Project Methods
The NMR facility is located in Gortner Laboratory of Biochemistry with a newly acquired Varian Unity Inova 400MHz spectrometer. The instrument has a 9.46 Tesla shielded magnet and a Nalorac 4 Nuc probe which is tunable to proton, carbon-13, fluorine or phosphorus. The operation of the lab is run in conjunction with the Center for Mass Spectrometry and Proteomics under the supervision of Thomas Krick, Senior Scientist. For those considering NMR projects, staff consultation is given on the feasibility of the project and the preparation of the samples. Samples are then run and spectra with their interpretation given back to the user. For those who have run NMR before or undertake long-term projects, training to operate the instrument would be appropriate and given.

                            Gander Project: Pencicillium species secrete phosphocholine-phoethanamine-containing glycopeptides if the medium is below pH 4 and phosphoglycoenzymes if the pH is above 5. The enzymes are being anayzed by NMR spectroscopy: they are all lytic enzymes which degrade carbohydrates and phosphorylated substances. None are proteases. The pH of the medium increases as carbohydrate is depleted and organic acids are taken up. The function of the phosphocholine-/phosphoethanolamine-containing regions are under investigation. Woodward Project: Buried, labile H atoms of proteins undergo isotopic exchange with solvent H atoms. This indicates that the compact, tightly packed protein structure undergoes internal fluctuations that expose buried sites to solvent. This inherent flexibility of proteins is thought to be a fundamental aspect of the biological activity of proteins. Hydrogen isotope exchange studies can be employed to characterize these motions. We use NMR spectroscopy to determine the hydrogen exchange kinetics of assigned H atoms. Nelsestuen Project: Research has involved the vitamin K-dependent proteins and their unique calcium-binding functions. Lanthanide ions which are paramagenetic and broaden adjacent signals were substituted for calcium ions. Bound lanthanides were measured by monitoring lanthanide-induced changes in buffer signals.

                              The 13C and 31P nuclear magnetic resonance spectroscopy has shown that a new class of fungal extracellular hydrolases are glycoproteins which contain phosphoethanolamine and phosphocholine residues covalently attached to a large galactomannan. These hydrolases degrade polysaccharides and phosphorylated substances in the fungi's environment. The role of the phosphoethanolamine and phosphocholine is being sought. The 13C NMR spectroscopy has shown that the structure of the extracellular polysaccharide secreted by three strains of Yogurt producing bacteria are identical, although the percentage of galactose, glucose and mannose are different in each polymer. These polysaccharides have properties which influence the texture of yogurt. Proton NMR spectroscopy has shown that cooperative metal ion binding occurs in a prothrombin phospholipid system. The role of metal ions in the blood clotting process is under investigation. Proton NMR spectroscopy is being used to measure the rate of exchange of peptide NH protons with those in water. Protons buried in native proteins exchange slowly; the exchange rate increases as the protein unfolds. The rate of exchange of those proteins whose chemical shifts are located under the main aromatic envelope of the spectrum have been investigated as a function of pH and temperature. Proton NMR spectra of oligo- and polysaccharides useful in identifying N-acetylamannosamine and N-acetylmannosaminuronic acid have been found.

                                Nuclear Magnetic Resonance (NMR) spectroscopy is useful in establishing the structure and concentrations of substances found in living systems. This technique is also used to follow the concentrations of metabolites in vivo. An NMR spectroscopy laboratory was established in the Department in August with a 70.5 KGauss superconducting NMR spectrometer with Fourier transform capability attached to a computer with 128 K of memory. A period of 2 to 3 months was required for the operator to become familiar with the operation and capability of the instrument. During the past two months the instrument has been used to determine the structures of samples provided by scientists in the Departments of Biochemistry, Entomology and Plant Pathology. These samples represent substances in the categories of polysaccharides, proteins, toxins, degradation products from bacteria and insecticides. We anticipate an increasing use of this facility as scientists doing agricultural research become more familiar with the wide variety of ways in which an NMR spectrometer may be used in their specific research programs.
