Protein Structure Determination
The Protein Structure Determination capability provides insights into the molecular structure of proteins, and how proteins form interactions with other molecules, for example, protein-protein, protein-DNA, protein-drug and protein-lipid complexes.
This capability uses X-ray crystallography and biophysical characterisation tools, such as circular dichroism spectroscopy, to visualise the structures.
This capability is home to a range of instrumentation listed here
Aviv Biomedical Circular Dichroism Spectrometer - used to determine the secondary structure of proteins and peptides in aqueous solution.
Agilent Technologies SuperNova X-ray Diffractometer - provides an in-house X-ray source for measuring diffraction of protein crystals for the subsequent determination of the three-dimensional structure.
Australian Synchrotron – La Trobe has access to the Macromolecular & Micro Crystallography beamline which is an X-ray source used to rapidly create diffraction patterns of protein crystals for the subsequent determination of the three-dimensional structure.
Gryphon crystallisation robot and Memmert crystallisation incubators – used to grow protein crystals for subsequent structural analysis
There is a broad range of applications that this capability can assist you with including:
- Three-dimensional structure determination of biological macromolecules at near atomic resolution
- Understanding structure-function relationship of biological molecules
- Atomic details of biological molecule-ligand interactions
- Structure-based drug design
We provide advice on experimental design and methodology.
