Structural Biology

structuralbiologybanner

In the structural biology theme, X-ray crystallography and NMR are combined as extremely powerful techniques to explore the structure of macromolecules at the highest level of atomic detail. The dynamic behaviour of proteins in solution and how they assemble into their complex folds is explored, with emphasis on protein mis-folding in disease states such as Alzheimer's. High power electron and atomic force microscopy is used to visualise biological assemblies and processes directly, while complementary fluorescence microcopy is used to visualise complex organisation and localisation in vivo. Such large datasets require expertise in computational biology to analyse and interpret results.

Structural biology research in our department at a glance:

  • X-ray protein crystallographyprotein complexes, especially of toxins and virulence factors, protein/DNA interactions, drug design
  • Nuclear magnetic resonance spectroscopy (NMR)protein structure and dynamics, molecular interactions, ligand binding, high-pressure NMR
  • Complex imaging - fluorescence microscopy, electron microscopy (EM), atomic force microscopy (AFM), cryoelectron tomography
  • Computational biology - protein structure modelling, dynamic system modelling, image analysis
