DESCRIPTION (provided by applicant): We propose to establish a Rocky Mountain Regional NMR Center with a 900 MHz NMR serving a large number of Universities in the Rocky Mountain and Central Regions. The NMR Center will be situated on the new Fitzsimons campus of the University of Colorado Health Sciences Center, and will serve a productive group of NMR structural biologists in the areas of protein, nucleic acid and carbohydrate structure and function. The user group consists of 19 researchers at 8 Institutions. Space in the new Basic Research Building at Fitzsimons has been specifically designed for the unique siting requirements of a 900 MHz NMR and construction of the building is well underway. Recent developments in TROSY-type experiments allow acquisition of extremely high resolution NMR spectra on much larger macromolecules than was previously possible. These TROSY experiments are optimized at ultra-high fields, and the requested state-of-the-art 900 MHz NMR spectrometer and cryoprobe will make it possible for the users to take advantage of these powerful new techniques. The primary goal of the Center will be to provide routine access to the unique capabilities of the 900 MHz NMR in order to accelerate their biological and biomedical research programs. In addition to acquiring their NMR data on-site, experienced users will be able to acquire 900 MHz NMR data over the Internet with the aid of facility staff. A second major goal of the NMR Center will be to establish and maintain a Web-based collaboratorium for sharing information and expertise in a set of six "focus areas." These focus areas are strengths of the user group and the collaboratorium will provide a valuable mechanism for experienced users to share their expertise with other users. The six initial focus areas for the NMR Center and Web collaboratorium are: Improved Resolution and Sensitivity for NMR Studies of Proteins; NMR Studies of Large Macromolecular Complexes; Studies of Protein and Nucleic Acid Dynamics; Improved Methods for NMR Studies of RNA and DNA; NMR Studies of Membrane Proteins; and Improved Spectral Resolution by Employing Reverse Micelles in Low Viscosity Solvents. A well designed organizational plan for administering the facility is presented which is modeled after plans at other established multi-user NMR and synchrotron facilities. Time on the 900 MHz NMR will be allocated based on written proposals which will be reviewed by a proposal review committee. NIH-funded research that requires the high field, high resolution, and unique capabilities of the 900 MHz NMR will be the highest priority for the center.
