A significant problem in biological X-ray crystallography is the radiation chemistry caused by the incident X-ray beam. This produces both global and site-specific damage. Site-specific damage can misdirect the biological interpretation of the structural models...

Metalloproteins play a key role in the progression of many diseases. Using ion beam analysis through particle-induced X-ray emission (PIXE) and anomalous X-ray analysis we have quantitatively identified the metal atoms in 30 previously structurally...

Xylose isomerase (XI) is an industrially important metalloprotein studied for decades. Its reaction mechanism has been postulated to involve the movement of the catalytic metal cofactor to several different conformations. Here, a dose-dependent approach was used to...

Dissociation of transforming growth factor beta-1 (TGF-β1) from the inhibitory protein latency-associated peptide (LAP) can occur from low doses of X-ray irradiation of the LAP–TGF-β1 complex, resulting in the activation of TGF-β1 and can have health-related...
