Desulfovibrio gigas ferredoxin II (FdII) contains a single 3Fe cluster [Huynh, B.H., Moura, J.J.G., Moura, I., Kent, T.A., LeGall, J., Xavier, A.V., and Münck, E. (1980) J. Biol. Chem. 255, 3242-3244]. In the oxidized state the protein exhibits an intense electron paramagnetic resonance (EPR) signal at g = 2.02. Upon one-electron reduction the center becomes EPR silent. In the presence of D. gigas crude cell extracts, devoid of acidic electron carriers and supplemented with pyruvate and FdII, an EPR signal typical of reduced [4Fe-4S] centers is obtained. The appearance of this signal correlates with the beginning of stimulation of the phosphoroclastic reaction as judged by the production of H2. These results, supported by the occurrence of easy chemical conversion of the 3Fe cluster of D. gigas ferredoxin into 4Fe structures [Moura, J.J.G., Moura, I., Kent, T.A., Lipscomb, J.D., Huynh, B.H., LeGall, J., Xavier, A.V., and Münch, E. (1982) J. Biol. Chem. 257, 6259-6267], suggest that cluster conversion takes place in conditions close to the situation in vivo. This cluster interconversion is discussed in the context of some of the relevant metabolic pathways of Desulfovibrio spp.
