As isolated from Rhodospirillum rubrum, the iron protein of nitrogenase has little or no activity. It can be activated by incubating it with a trypsin-sensitive, oxygen-labile component (activating factor) plus adenosine triphosphate and a divalent metal ion. After activation, the iron protein retains its nitrogenase activity when the activating factor is removed.
从深红红螺菌中分离得到的固氮酶铁蛋白几乎没有活性或完全没有活性。将其与一种对胰蛋白酶敏感、对氧不稳定的成分(激活因子)、三磷酸腺苷和二价金属离子一起孵育,可使其激活。激活后,去除激活因子时,铁蛋白仍保留其固氮酶活性。
