The amino acid sequence of ferredoxin (Fd) I, purified from Desulfovibrio vulgaris Miyazaki, has been established. Fd I is strikingly similar to Fd III of D. africanus Benghazi with 84% homology. Both have the sequence, -Cys-x-x-Asp-x-x-Cys-x-x-x-Cys-Pro- in the N-terminal half, and the sequence, -Cys-x-x-Cys-x-x-Cys-x-x-x-Cys-Glu- in the C-terminal half of the molecule, instead of the common sequences for ligation to the usual [4Fe-4S] clusters. Fd I has 76% homology to Fd II of D. desulfuricans Norway.
已确定从普通脱硫弧菌宫崎株中纯化得到的铁氧化还原蛋白(Fd)I的氨基酸序列。Fd I与非洲脱硫弧菌班加西株的Fd III极为相似,同源性达84%。二者在分子的N端一半均具有-Cys-x-x-Asp-x-x-Cys-x-x-x-Cys-Pro-序列,在C端一半具有-Cys-x-x-Cys-x-x-Cys-x-x-x-Cys-Glu-序列,而非与常见的[4Fe-4S]簇连接的常见序列。Fd I与脱硫脱硫弧菌挪威株的Fd II具有76%的同源性。
