Center for Structural Biology
The newly formed Center for Structural Biology (CSB) will serve as the focus for structural biology activities across the CCR. The Center's foundation is built from the merger of the Structural Biophysics Laboratory and the Macromolecular Crystallography Laboratory.
The Center will: 1) plan, develop and conduct research studies on the molecular structure and interactions of biological macromolecules and therapeutics pertinent to human health, with a particular emphasis on cancer and infection; 2) support training of personnel in advanced structural methods; 3) develop and apply new tools for molecular characterization using novel biophysical and biochemical techniques including cryo-electron microscopy, nuclear magnetic resonance (NMR) spectroscopy, x-ray diffraction and scattering methods; 4) lead methods development to enable full understanding of large, multi-component molecular machines; and 5) apply structural and chemical insights to develop mechanistic understanding to inform therapeutics strategies.

The Center for Structural Biology offers several resources to CCR and other NIH intramural investigators.
The Biophysics Resource (BR), operated by the Center, provides CCR investigators with access to both the latest instrumentation and expertise in characterizing the biophysical aspects of systems under structural investigation.
The Biophysics Resource operates as an open, shared-use facility; in general, BR users learn to operate the instruments and conduct their own experients. Our staff members train all first-time users and are also available to consult with investigators on experimental design/analysis or collaborate with them on more complex studies. To learn more, visit the Biophysics Resource.
The mission of the SAXS Core Facility is to provide support to research projects from CCR principal investigators (PIs), NIH intramural PIs and extramural academic research groups and laboratories. The support includes providing routine access to the APS PUP SAXS/WAXS beamline and in-house SAXS instrument, and expertise in experimental design, data collection, processing, analysis and interpretation. Our main focus is to determine the structure of biomacromolecules and their complexes in solution. The research field includes, but is not limited to, structural studies of nucleic acids, proteins, protein assemblies, virus particles, lipid membranes, protein/DNA and protein/RNA complexes.

NMR Facility for Biological Research
Within the Center is a state-of-the-art nuclear magnetic resonance (NMR) facility that researchers use to solve atomic resolution three-dimensional (3D) structures, probe molecular dynamics, and aid in structure-based drug design and molecular targeting. The facility is managed by Dr. Janusz Koscielniak, who is an expert in NMR spectrometer hardware and software. The instruments have been used to study how nucleic acids bind inhibitors, define new functional interaction sites in biomachines, and to reveal structural and dynamic properties critical to biological function.
