  • Title: The strength of EPR and ENDOR techniques in revealing structure-function relationships in metalloproteins.
    Author: Van Doorslaer S, Vinck E.
    Journal: Phys Chem Chem Phys; 2007 Sep 07; 9(33):4620-38. PubMed ID: 17700864.
    Abstract:
    Recent technological and methodological advances have strongly increased the potential of electron paramagnetic resonance (EPR) and electron nuclear double resonance (ENDOR) techniques to characterize the structure and dynamics of metalloproteins. These developments include the introduction of powerful pulsed EPR/ENDOR methodologies and the development of spectrometers operating at very high microwave frequencies and high magnetic fields. This overview focuses on how valuable information about metalloprotein structure-function relations can be obtained using a combination of EPR and ENDOR techniques. After an overview of the historical development and a limited theoretical description of some of the key EPR and ENDOR techniques, their potential will be highlighted using selected examples of applications to iron-, nickel-, cobalt-, and copper-containing proteins. We will end with an outlook of future developments.
