The primary structure of a ferredoxin isolated from D. desulfuricans Norway strain, which we called ferredoxin II (Fd II) has been elucidated. This ferredoxin is a dimer constituted of two identical subunits of molecular weight 6000. In ferredoxin II two (4 Fe-4 S) centers are present per subunit instead of one (Fe-S) center as is the case for the other ferredoxins isolated from Desulfovibrio and for Fd I from the same organism. The comparison of amino-acid sequences shows that ferredoxin II presents more homologies with clostridial type ferredoxin than with the ferredoxins from D. gigas and D. africanus.
我们已经阐明了从脱硫脱硫弧菌挪威菌株中分离出的一种铁氧化还原蛋白的一级结构，我们将其称为铁氧化还原蛋白II（Fd II）。这种铁氧化还原蛋白是一种二聚体，由两个分子量为6000的相同亚基组成。在铁氧化还原蛋白II中，每个亚基存在两个（4Fe-4S）中心，而不是像从脱硫弧菌中分离出的其他铁氧化还原蛋白以及同一生物体中的Fd I那样存在一个（Fe-S）中心。氨基酸序列的比较表明，铁氧化还原蛋白II与梭菌型铁氧化还原蛋白的同源性比与巨大脱硫弧菌和非洲脱硫弧菌的铁氧化还原蛋白的同源性更高。
