|40 ATP + 40 H2O + N2 + 12 reduced [2Fe-2S]-[ferredoxin] <=> 40 ADP + 26 H(+) + 3 H2 + 2 NH4(+) + 12 oxidized [2Fe-2S]-[ferredoxin] + 40 phosphate|
- This enzyme, originally isolated from the bacterium Azotobacter
vinelandii, is a complex of two components (namely dinitrogen
reductase and dinitrogenase).
- Dinitrogen reductase is a [4Fe-4S] protein, which, in the presence of
ATP, transfers an electron from ferredoxin to the dinitrogenase
- Dinitrogenase is a vanadium-iron protein that reduces dinitrogen to
two molecules of ammonia in three successive two-electron reductions
via diazine and hydrazine.
- Compared with EC 126.96.36.199, this enzyme produces more dihydrogen and
consumes more ATP per dinitrogen molecule being reduced.
- Unlike EC 188.8.131.52, this enzyme can also use CO as substrate,
producing ethylene, ethane and propane.
