A novel iron-sulfur protein from the photosynthetic purple bacterium Rhodopseudomonas palustris was purified to homogeneity and identified as a ferredoxin on the basis of its physicochemical properties. Based on the uv/vis spectrum, iron quantitation, cyclic voltammetry, EPR, and 1H NMR data, the ferredoxin is found to contain two iron-sulfur clusters, one [3Fe-4S] and one [4Fe-4S], which places this protein in the class of 7Fe ferredoxins. The voltammetric peak potentials of the two clusters are -0.260 and -0.560 V at pH 8.0. The molecular mass around 19 kDa makes this protein the heaviest known in this class. This paper further demonstrates the diagnostic power of magnetic resonance spectroscopies in recognition of the two types of clusters in iron-sulfur proteins.
