The nitrogenase system of Spirillum lipoferum was separated into three components, the normal Mo-Fe and Fe proteins as well as an activating factor for the Fe protein. The rate of activation is increased by Mn2+ or by an excess of Mg2+, and the process requires ATP.
脂螺菌的固氮酶系统可分为三个组分,即正常的钼铁蛋白和铁蛋白以及铁蛋白的激活因子。锰离子或过量的镁离子可提高激活速率,且该过程需要ATP。
