Biophysics & Macromolecular Structures
What are Biophysics & Macromolecular Structures?
Biophysical & Macromolecular Structural research views biological problems through the lens of physics. Biophysicists and macromolecular structural biologists work to decipher how changes to protein or nucleic acid sequence might lead to changes in their 3D architecture and therefore their function in the cell.
What is the impact of our research in Biophysics & Macromolecular Structure?
- Drug development efforts can circumvent problems with drug resistant pathogens using the Substrate Envelope Theory of Drug Resistance that was first put forth by our department. This theory states that compounds that fit into the enzymatically active substrate envelope of the protein, like a key into a lock, leave less wiggle-room for the protein to mutate and become resistant to that drug. This theory was developed through the analysis of hundreds of 3D protein structures bound to different drugs. Find out more here.
- The biophysical basis for how protein folding is coupled to biological activity is actively under investigation in our department. Some proteins only fold upon binding to their cellular substrates, providing new ways to target these proteins with novel therapeutics. Researchers in our department employ nuclear magnetic resonance spectrometry (similar to an MRI you might get at a hospital, but for much smaller macromolecules) to directly visualize how each atom in a protein changes as it binds to its cellular partners. Find out more here.
- Fundamental processes required for viral replication and infection are being elucidated by studying the physical structures of the proteins involved in these processes. Find out more here and here.
