CC   -!- CATALYTIC ACTIVITY: Ammonia + 3 NAD(+) + 2 H(2)O = nitrite + 3
CC       NADH.
CC   -!- COFACTOR: Binds 1 siroheme per subunit.
CC   -!- COFACTOR: Binds 1 4Fe-4S cluster per subunit.
CC   -!- COFACTOR: FAD.
CC   -!- PATHWAY: Nitrogen metabolism; nitrate reduction (assimilation).
CC   -!- SUBUNIT: Homodimer which associates with NirD.
CC   -!- SIMILARITY: Belongs to the nitrite and sulfite reductase 4Fe-4S
CC       domain family. {ECO:0000305}.
