Crystallography and Computational Biosciences

Overview

The Crystallography and Computational Biosciences Shared Resource serves as a portal for access to state-of-the-art X-ray crystallographic equipment, technical support, high-performance computing, and scientific consultation for Cancer Center researchers. The Shared Resource exists to meet the growing needs for structure determination and computational analysis of protein and DNA/RNA structure, function and dynamics for a diverse array of projects ranging from basic science questions to drug design.

Mission

Macromolecular X-ray crystallography is an experimental method to determine the three-dimensional structure of proteins, DNA/RNA, their complexes, and the complexes of a variety of ligands including cofactors, substrates, drug candidates, etc. The Computational Bioscience portion of resource provides access to cutting-edge modeling and simulation methods. The information from these complementary approaches can be used to develop novel therapies, as it is essential for assessing and exploiting the biological function of the target protein. The CCB resource provides support for ongoing projects and the development of new projects through the collection of preliminary data for funding applications.

 

About X-ray Crystallography  

Macromolecular X-ray crystallography is an experimental scientific method to determine the three-dimensional structure of proteins, DNA/RNA, their complexes, and the complexes of a variety of ligands including cofactors, substrates, drug candidates, etc. We use this information to develop novel therapies, as it is essential for assessing and exploiting the biological function of the target protein.

About Our X-ray Technology  

The X-ray facility houses Rigaku Saturn 92-Micromax007 and RaxisIV/RUH diffractometer with dual VariMx-HF Confocal Optic Systems and all the necessary ancillary equipment (e.g. microscopes, crystallization cabinets, and cryo-cooling devices). The facility was upgraded in 2012 with funds from the North Carolina Center for Biotechnology, as part its move to Wake Forest Biotech Place.   

A few recent collaborations include: 

  • Development of PI3K-kinase inhibitors
  • Development of fatty acid synthase inhibitors
  • Dissection of the molecular basis for peroxiredoxin inactivation and repair by sulfiredoxin
  • Structure and function of the mammalian TREX1 3' exonuclease and RNase H2 enzymes 

    About Computational Biosciences 

    The Computational Bioscience portion of the Crystallography and Computational Biosciences Shared Resource provides access to cutting-edge modeling and simulation methods through consultation and collaboration with the director, Fred Salsbury, PhD.

    Our main expertise lies in structure-based classical modeling, docking and analysis, but additional expertise exists in computational biology/bioinformatics, and in quantum mechanical calculations. A few recent collaborations include:

    • Molecular simulations of mismatch repair proteins
    • Molecular simulations of redox proteins
    • Analysis of communication within proteins based on molecular simulations
    • Computational modification and docking of drug leads into active sites
    • Quantum mechanical calculations of model systems of  novel DNA-Zn interactions
