J. 293:101-107(1993). CC -!- FUNCTION: The key enzymatic reactions in nitrogen fixation are CC catalyzed by the nitrogenase complex, which has 2 components: the CC iron protein (component 2) and a component 1 which is either a CC molybdenum-iron protein, a vanadium-iron, or an iron-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 -!- COFACTOR: Iron-sulfur. CC -!- SUBUNIT: Hexamer of two alpha, two beta, and two delta chains. CC -------------------------------------------------------------------------- CC This Swiss-Prot entry is copyright.
