Natural and recombinant prion structure from X-ray fiber diffraction

Work by researchers from Vanderbilt University and the University of California, San Francisco has revealed an unexpected conclusion about prions, the proteins responsible for several infectious diseases of the nervous system in mammals, including bovine spongiform encephaolopathy, or "mad cow" disease. The researchers compared the structure of natural prions with their genetically engineered counterparts and found unexpectedly large differences. These differences may help explain why the recombinant versions, which are used to study such diseases, are not as infectious as natural prions. The work was conducted at BioCARS biosafety level 2 (BSL-2) facilities under an agreement with BioCAT (APS sector 18).

Staff Member Contributes to Fiber Diffraction Workshop

October 2009 - BioCARS beamline scientist Robert Henning participated in a workshop on fiber diffraction hosted by BioCAT (APS beamline 18-ID). The event included a demonstration of fiber crystallography capabilities at BioCARS beamline 14-BM-C.

BioCARS and BioCAT have complementary techniques for this type of study and have made collaborative arrangements under which users may work at both facilities.

BioCARS is a national user facility for synchrotron-based macromolecular crystallography at Sector 14 of the Advanced Photon Source, Argonne National Laboratory. BioCARS is an integral part of the multi-institutional and multi-disciplinary Consortium for Advanced Radiation Sources (CARS), managed by the University of Chicago Center for Advanced Radiation Sources.

The mission of BioCARS is to develop the resources and facilities necessary to foster frontier research in the field of macromolecular crystallography. BioCARS provides state-of-the art facilities, scientific and technical support for Laue and time-resolved crystallography, studies of macromolecular assemblies that form crystals with large unit cells, MAD phasing, and ultra-high resolution crystallography. In all cases, the goal is to understand basic biological processes in structural terms, at the atomic resolution level. Scientific problems addressed by BioCARS users and staff are fundamental to basic science, highly relevant to significant biomedical problems and of great practical importance to the pharmaceutical and biotechnology industries.

BioCARS operates two experimental stations, embedded in a Biosafety Level 3 (BSL-3) facility. This BSL-3 synchrotron-based capability is unique in the United States and permits safe studies of biohazardous materials, such as pathogenic human viruses.
