Abstract

We present iron extended X-ray absorption fine structure (EXAFS) spectra of a photosystem I core preparation containing F_X, the very low potential iron–sulfur cluster in photosystem I. The preparation lacks F_A and F_B. The amplitude of Fe–Fe backscattering in the EXAFS spectrum indicates that F_X may be a [4Fe-4S] cluster and is not a [2Fe-2S] cluster or clusters.
