CC   -!- FUNCTION: The key enzymatic reactions in nitrogen fixation are
CC       catalyzed by the nitrogenase complex, which has 2 components: the
CC       iron protein and the molybdenum-iron protein.
CC   -!- CATALYTIC ACTIVITY: 3 reduced ferredoxin + 6 H(+) + N(2) + n ATP =
CC       3 oxidized ferredoxin + 2 NH(3) + n ADP + n phosphate.
CC   -!- SUBUNIT: Tetramer of two alpha and two beta chains that binds 30-
CC       32 Fe, 2 Mo, and inorganic sulfur.
CC   -!- SIMILARITY: Belongs to the nifD/nifK/nifE/nifN family.
