Primary structure of the two (4 Fe-4 S) clusters ferredoxin from Desulfovibrio desulfuricans (strain Norway 4).
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.
