Abstract:
High-frequency electron paramagnetic resonance (HF-EPR) allows
obtaining detailed information on the anisotropy of integer-spin
systems, which are usually silent at conventional EPR frequencies (X-
or Q-bands). However, the studies performed so far on integer-spin
systems have mostly dealt with synthetic complexes. In this paper, we
present first results obtained on a mononuclear high-spin ferrous iron
center of a rubredoxin-type protein. This study shows that the
broadband quasi-optical technique of HF-EPR is a suitable approach
towards the study of biologically relevant metal centers with large
zero-field splittings.
