enzyme consists of 2 proteins: a molybdenum and iron-containing protein, MoFe protein, component I, dinitrogenase, and an iron containing protein, Fe protein, component II, dinitrogenase reductase, together they form the active nitrogenase complex |

the nitrogenase activity is resolved into two components. The component 1 has a molecular size of approximately 250 kDa, as estimated by gel filtration, and sodium dodecyl sulfate-polyacrylamide gels reveals two predominant bands with molecular sizes near 57000 and 62000 Da, consistent with an alpha2beta2 tetramer as in eubacterial component 1 proteins. For the component 2 a molecular size of approximately 120000 Da is estimated by gel filtration, with a subunit molecular size near 31000 Da, indicating that the component 2 protein is a tetramer |
