【 摘 要 】

The oxidizability of a redox couple, [4Fe-4S], in a 7Fe ferredoxin extracted from Pseudomonas ovalis was monitored by ¹H-NMR. The iron-sulfur cluster in the ferredoxin was not only reducible (Nagayama et al., 1983) but also oxidizable in its native form. This result provided the first verification of 3 redox states for a redox center in ferredoxin, 4Fe, in the native form of the protein.
