    GO:0018697    carbonyl sulfide nitrogenase activity    Catalysis of the reaction: carbonyl sulfide + 2 H+ + 2 e- = hydrogen sulfide + carbon monoxide.
    GO:0051536    iron-sulfur cluster binding    Interacting selectively and non-covalently with an iron-sulfur cluster, a combination of iron and sulfur atoms.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0016163    nitrogenase activity    Catalysis of the reaction: 8 reduced ferredoxin + 8 H+ + nitrogen + 16 ATP = 8 oxidized ferredoxin + 2 NH3 + 16 ADP + 16 phosphate.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
biological process
    GO:0009399    nitrogen fixation    The process in which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes, such as ammonia, nitrate and nitrogen dioxide.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
cellular component
    GO:0016612    molybdenum-iron nitrogenase complex    An enzyme complex containing a molybdenum-iron cluster found in many species. It is composed of two proteins, dinitrogenase and nitrogenase reductase; dinitrogenase, the molybdenum-iron protein, is tetrameric with an alpha2-beta2 structure, and nitrogenase reductase is a homodimer.
