Ferredoxin from Desulfovibrio desulfuricans was isolated, purified and crystallized. It contains four iron atoms and four sulphido or ;acid-labile' sulphur atoms for a molecule of 6000 daltons. The absorption spectrum in the u.v.-visible region and the electron-paramagnetic-resonance signals of the reduced protein are similar to those observed for other four-iron ferredoxins. The amino acid composition is different from that of Desulfovibrio gigas ferredoxin. The redox potential of -0.33V at pH7.0 was determined by dye techniques.
从脱硫脱硫弧菌中分离、纯化并结晶出了铁氧化还原蛋白。它含有四个铁原子和四个硫原子或“酸不稳定”硫原子,分子量为6000道尔顿。还原态蛋白质在紫外 - 可见光区域的吸收光谱和电子顺磁共振信号与其他四铁铁氧化还原蛋白所观察到的相似。其氨基酸组成与巨大脱硫弧菌铁氧化还原蛋白不同。通过染料技术测定在pH7.0时的氧化还原电位为 -0.33V。
