EPR of Radical Intermediates in Flavoenzymes

We have surveyed the literature from the past ten years for EPR studies of flavoproteins. We concentrate on characterization of the flavin cofactor, in its anion or neutral radical forms, with both CW and pulsed EPR and ENDOR, but do not completely exclude other paramagnetic species which are also formed in electron-transfer processes. More detailed discussion of experiments on the metal centres can be found elsewhere, including the chapter by Hiittermann and Kappl in this volume. 

We have attempted to divide this chapter into several main categories metal-free flavoproteins, hemoflavoproteins and iron-sulfur-containing flavoproteins, although the reader may And that due to overlap some sections appear where they might not have been expected.
