Abstract
A previously unknown ferredoxin has been isolated and purifiedfrom anaerobic growth of the photosynthetic bacterium Rps. palustris. Cyclic voltammetric experiment gives clear indication of tworedox steps, one around -120 mV and the other around -550 mVversus NHE. H-1 NMR experiments on the three redox statesprovide a clear-cut identification of a [3Fe-4S] and a [4Fe-4S] clusters
