Biophysical chemistry

Definition

Biophysical chemistry is the study of the physical properties of biological macromolecules at either a chemical sequence level or a more global structural level. Biophysical chemistry is also used to describe techniques suited to understanding the physical properties of biological molecules at a chemical level, including nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography.

    Water is increasingly recognized as being of paramount importance in biological processes, yet its exact role remains difficult to elucidate. Now, the motion of water molecules within and around a synthetic peptide-amphiphile nanofibre has been precisely determined, showing significant differences between its core and surface.

    Proteolysis-targeting chimera (PROTACs) are synthetic molecules that recruit neo-substrate proteins to a ubiquitin ligase for ubiquitination and subsequent degradation. Structural insight into the VHL–MZ1–BRD4 complex reveals how the rationally designed MZ1–PROTAC molecule mediates degradation of an unnatural protein substrate.
