dc.description.abstract | We describe two new characteristics of the EPR of the seven-iron containing ferrodoxin from Thermus thermophilus. First, the reduced state of the 3Fe center, which has traditionally been considered to be EPR-silent, has been found to exhibit [Delta]m = 4 transition, which is unique for Fe-S centers. This signal is similar to that of high-spin Fe2+-EDTA and supports the suggestion that the ground electronic state of the 3Fe cluster is S = 2. Second, we have recorded the EPR spectrum of the fully reduced protein at 9 and 15 GHz and found that changes occur in the signal which are consistent with a weak electronic spin-spin interaction between the [4Fe-4S]+ (S = 1/2) and the reduced 3Fe center. A theoretical explanation is given for the observation of interaction signals with constant effective g values. | en_US |
