CC -!- FUNCTION: Catalyzes the production of nitric oxide.
CC {ECO:0000256|ARBA:ARBA00002642, ECO:0000256|PIRNR:PIRNR037219}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 L-arginine + 4 O2 + 3 reduced [flavodoxin] = 5 H(+) + 4 H2O
CC + 2 L-citrulline + 2 nitric oxide + 3 oxidized [flavodoxin];
CC Xref=Rhea:RHEA:52324, Rhea:RHEA-COMP:10622, Rhea:RHEA-COMP:10623,

CC ChEBI:CHEBI:57743, ChEBI:CHEBI:58210; EC=1.14.14.47;
CC Evidence={ECO:0000256|ARBA:ARBA00000737};
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000256|ARBA:ARBA00001971,
CC ECO:0000256|PIRNR:PIRNR037219, ECO:0000256|PIRSR:PIRSR037219-1};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|PIRNR:PIRNR037219}.
CC -!- MISCELLANEOUS: This protein is similar to the oxygenase domain of
CC eukaryotic nitric oxide synthases but lacks the reductase domain which,
CC in eukaryotes, is responsible for transfer of electrons to the ferric
CC heme during nitric oxide synthesis. {ECO:0000256|PIRNR:PIRNR037219}.
CC -!- SIMILARITY: Belongs to the NOS family. Bacterial NOS oxygenase
CC subfamily. {ECO:0000256|ARBA:ARBA00005411,
CC ECO:0000256|PIRNR:PIRNR037219}.
