Electron Paramagnetic Resonance (EPR) Facility

The primary mission of the electron paramagnetic resonance (EPR) facility is to determine structural details of proteins that contain paramagnetic centers. It is operated in conjunction with the Center for the Study of Early Events in Photosynthesis and directed by Dr. LoBrutto of the School of Life Sciences. It is used to characterize a wide variety of biochemical systems, providing information on an atomic scale in free radicals and in the vicinity of certain paramagnetic metal ions. Changes in structure often occur during the functional cycle of a protein, and tracking these changes by EPR has become a much-used technique for determining mechanism and function from structure.
